effort to determine whether to amend the current energy conservation
standards for direct heating equipment. Under the Energy Policy and
Conservation Act of 1975, as amended (``EPCA''), DOE must periodically
review these standards and publish either a notice of proposed
rulemaking (``NOPR'') to propose new standards for direct heating
equipment or a notice of determination that the existing standards do
not need to be amended. This request for information (``RFI'') solicits
information from the public to help DOE determine whether amended
standards for direct heating equipment would result in significant
energy savings and whether such standards would be technologically
feasible and economically justified. DOE welcomes written comments from
the public on any subject within the scope of this document (including
topics not raised in this RFI).

I. Introduction
A. Authority and Background
The Energy Policy and Conservation Act of 1975, as amended
(``EPCA'' or ``the Act''),\1\ Public Law 94-163 (42 U.S.C. 6291-6317,
as codified), among other things, authorizes DOE to regulate the energy
efficiency of a number of consumer products and industrial equipment.
(42 U.S.C. 6291-6317, as codified) Title III, Part B \2\ of EPCA
established the Energy Conservation Program for Consumer Products Other
Than Automobiles, which sets forth a variety of provisions designed to
improve energy efficiency. These products include direct heating
equipment (DHE), the subject of this document. (42 U.S.C. 6292(a)(9))
EPCA prescribed energy conservation standards for these products and
directed DOE to conduct two cycles of rulemakings to determine whether
to amend these standards. (42 U.S.C. 6295(e)(3) and (4))
---------------------------------------------------------------------------
\1\ All references to EPCA in this document refer to the statute
as amended through America's Water Infrastructure Act of 2018,
Public Law 115-270 (Oct. 23, 2018).
\2\ For editorial reasons, upon codification in the U.S. Code,
Part B was redesignated Part A.
---------------------------------------------------------------------------
Under EPCA, DOE's energy conservation program consists essentially
of four parts: (1) Testing, (2) labeling, (3) Federal energy
conservation standards, and (4) certification and enforcement
procedures. Relevant provisions of the Act specifically include
definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293),
labeling provisions (42 U.S.C. 6294), energy conservation standards (42
U.S.C. 6295), and the authority to require information and reports from
manufacturers (42 U.S.C. 6296).
Federal energy efficiency requirements for covered products
established under EPCA generally supersede State laws and regulations
concerning energy conservation testing, labeling, and standards. (42
U.S.C. 6297) DOE may, however, grant waivers of Federal preemption in
limited instances for particular State laws or regulations, in
accordance with the procedures and other provisions of EPCA. (42 U.S.C.
6297(d))
DOE completed the first of the required rulemaking cycles in 2010
by publishing a final rule on April 16, 2010 (``April 2010 final
rule'') that adopted amended performance standards for certain DHE
(i.e., vented home heating equipment) manufactured on or after April
16, 2013. 75 FR 20112. In the April 2010 final rule, DOE did not issue
standards for unvented home heating equipment, a subset of DHE, finding
that such standards would produce insignificant energy savings. Id at
20130. Additionally, DOE completed a second rulemaking cycle for DHE by
issuing a final determination to not amend standards for vented home
heating equipment and to not to adopt standards for unvented home
heating equipment on October 17, 2016 (``October 2016 final
determination''). 81 FR 71325. The current energy conservation
standards for DHE are located in title 10 of the Code of Federal
Regulations (``CFR'') part 430, section 32(i)(2). The currently
applicable DOE test procedures for unvented and vented DHE appear at 10
CFR part 430, subpart B, appendix G and appendix O, respectively.
In the October 2016 final determination, DOE concluded that energy
conservation standards should not be amended for DHE. DOE determined
that the DHE market characteristics at the time were largely similar to
those during the analysis for the April 2010 final rule, and that the
technologies available for improving DHE energy efficiency had not
advanced significantly since the publication of the April 2010 final
rule. In addition, DOE determined that the conclusions reached in the
April 2010 final rule regarding the benefits and burdens of more
stringent standards for DHE were still relevant to the DHE market.
Therefore, DOE concluded that amended energy conservation standards
would not be economically justified. 81 FR 71325, 71325 (Oct. 17,
2016).
EPCA also requires that, not later than 6 years after the issuance
of any final rule establishing or amending a standard, DOE evaluate the
energy conservation standards for each type of covered product,
including those at issue here, and publish either a notice of
determination that standards do not need to be amended, or a NOPR
including new proposed energy conservation standards (proceeding to a
final rule, as appropriate). (42 U.S.C. 6295(m)(1)) EPCA further
provides that, not later than 3 years after the issuance of a final
determination not to amend standards, DOE must publish either a notice
of determination that standards for the product do not need to be
amended, or a NOPR including new proposed energy conservation standards
(proceeding to a final rule, as appropriate). (42 U.S.C. 6295(m)(3)(B))
DOE must make the analysis on which the determination is based publicly
available and provide an opportunity for written comment. (42 U.S.C.
6295(m)(2)) In making a determination, DOE must evaluate whether more-
stringent standards would: (1) Yield a significant savings in energy
use and (2) be both technologically feasible and economically
justified. (42 U.S.C. 6295(m)(1)(A)) DOE is publishing this RFI to
collect data and information to inform its decision consistent with its
obligations under EPCA.
B. Rulemaking Process
DOE must follow specific statutory criteria for prescribing new or
amended standards for covered products. EPCA requires that any new or
amended energy conservation standard be designed to achieve the maximum
improvement in energy or water efficiency that is technologically
feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) To
determine whether a standard is economically justified, EPCA requires
that DOE determine whether the benefits of the standard exceed its
burdens by, to the greatest extent practicable, considering the
following seven factors:
(1) The economic impact of the standard on the manufacturers and
consumers of the affected products;
(2) The savings in operating costs throughout the estimated average
life of the product compared to any increases in the initial cost, or
maintenance expenses;
(3) The total projected amount of energy and water (if applicable)
savings likely to result directly from the standard;
(4) Any lessening of the utility or the performance of the products
likely to result from the standard;
(5) The impact of any lessening of competition, as determined in
writing by the Attorney General, that is likely to result from the
standard;
(6) The need for national energy and water conservation; and
(7) Other factors the Secretary of Energy (Secretary) considers
relevant.
(42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII))
DOE fulfills these and other applicable requirements by conducting
a series of analyses throughout the rulemaking process. Table I.1 shows
the individual analyses that are performed to satisfy each of the
requirements within EPCA.

------------------------------------------------------------------------
As detailed throughout this RFI, DOE is publishing this document
seeking input and data from interested parties to aid in the
development of the technical analyses on which DOE will ultimately rely
to determine whether (and if so, how) to amend the standards for direct
heating equipment.
II. Request for Information and Comments
In the following sections, DOE has identified a variety of issues
on which it seeks input to aid in the development of the technical and
economic analyses regarding whether amended standards for DHE may be
warranted. Additionally, DOE welcomes comments on other issues relevant
to this request for information that may not specifically be identified
in this document. In particular, DOE notes that under Executive Order
13771, ``Reducing Regulation and Controlling Regulatory Costs,''
Executive Branch agencies such as DOE are directed to manage the costs
associated with the imposition of expenditures required to comply with
Federal regulations. See 82 FR 9339 (Feb. 3, 2017). Pursuant to that
Executive Order, DOE encourages the public to provide input on measures
DOE could take to lower the cost of its energy conservation standards
rulemakings, recordkeeping and reporting requirements, and compliance
and certification requirements applicable to DHE while remaining
consistent with the requirements of EPCA.
A. Products Covered by This Process
The definitions for DHE were most recently amended in a test
procedure final rule. 80 FR 792 (Jan. 6, 2015). This RFI covers those
products that meet the definitions of ``direct heating equipment'' and
``home heating equipment,'' \3\ as codified at 10 CFR 430.2 and defined
as follows:
---------------------------------------------------------------------------
\3\ DOE notes that DHE is defined at 10 CFR 430.2 as ``vented
home heating equipment'' and ``unvented home heating equipment'';
however, the existing energy conservation standards apply only to
product classes of vented home heating equipment. There are no
existing energy conservation standards for unvented home heating
equipment.
---------------------------------------------------------------------------
(1) ``Direct heating equipment'' means vented home heating
equipment and unvented home heating equipment.
(2) ``Home heating equipment, not including furnaces'' means vented
home heating equipment and unvented home heating equipment.
1. Unvented Heaters
Unvented heaters are those products that meet the definitions for
``unvented home heating equipment,'' as codified at 10 CFR 430.2. DOE
defines unvented heaters and the various sub-types of unvented heaters
as follows:
(1) ``Unvented home heating equipment'' means a class of home
heating equipment, not including furnaces, used for the purpose of
furnishing heat to a space proximate to such heater directly from the
heater and without duct connections and includes electric heaters and
unvented gas and oil heaters.
(2) ``Electric heater'' means an electric appliance in which heat
is generated from electrical energy and dissipated by convection and
radiation and includes baseboard electric heaters, ceiling electric
heaters, floor electric heaters, portable electric heaters, and wall
electric heaters.
(3) ``Primary heater'' means a heating device that is the principal
source of heat for a structure and includes baseboard electric heaters,
ceiling electric heaters, and wall electric heaters.
(4) ``Supplementary heater'' means a heating device that provides
heat to a space in addition to that which is supplied by a primary
heater. Supplementary heaters include portable electric heaters.
(5) ``Baseboard electric heater'' means an electric heater which is
intended to be recessed in or surface mounted on walls at floor level,
which is characterized by long, low physical dimensions, and which
transfers heat by natural convection and/or radiation.
(6) ``Ceiling electric heater'' means an electric heater which is
intended to be recessed in, surface mounted on, or hung from a ceiling,
and which transfers heat by radiation and/or convection (either natural
or forced).
(7) ``Floor electric heater'' means an electric heater which is
intended to be recessed in a floor, and which transfers by radiation
and/or convection (either natural or forced).
(8) ``Portable electric heater'' means an electric heater which is
intended to stand unsupported, and can be moved from place to place
within a structure.
[[Page 6098]]
It is connected to electric supply by means of a cord and plug, and
transfers heat by radiation and/or convention (either natural or
forced).
(9) ``Wall electric heater'' means an electric heater (excluding
baseboard electric heaters) which is intended to be recessed in or
surface mounted on walls, which transfers heat by radiation and/or
convection (either natural or forced) and which includes forced
convectors, natural convectors, radiant heaters, high wall or valance
heaters.
(10) ``Unvented gas heater'' means an unvented, self-contained,
free-standing, non-recessed gas-burning appliance which furnishes warm
air by gravity or fan circulation.
(11) ``Unvented oil heater'' means an unvented, self-contained,
free-standing, non-recessed oil-burning appliance which furnishes warm
air by gravity or fan circulation.
Issue A.1 DOE requests comment on the definitions currently
applicable to unvented heaters and whether any of the definitions
should be revised, and if so, how. Please provide a rationale for any
suggested change. DOE notes that floor electric heaters are not
currently listed among the other types of heaters included in the
definition of a ``primary heater.'' DOE understands that floor electric
heaters have similar heat output as the types of heaters listed in the
definition of ``primary heater'' and may provide the primary source of
heat in small dwellings. DOE requests comment on whether floor electric
heaters should be specifically defined and also included in the
definition of ``primary heater.''
2. Vented Heaters
Vented heaters are those products that meet the definitions for
``vented home heating equipment,'' as codified at 10 CFR 430.2. DOE
defines vented heaters and the various sub-types of vented heaters as
follows:
(1) ``Vented home heating equipment'' or ``vented heater'' means a
class of home heating equipment, not including furnaces, designed to
furnish warmed air to the living space of a residence, directly from
the device, without duct connections (except that boots not to exceed
10 inches beyond the casing may be permitted) and includes: vented wall
furnace, vented floor furnace, and vented room heater.
(2) ``Vented floor furnace'' means a self-contained vented heater
suspended from the floor of the space being heated, taking air for
combustion from outside this space. The vented floor furnace supplies
heated air circulated by gravity or by a fan directly into the space to
be heated through openings in the casing.
(3) ``Vented room heater'' means a self-contained, free standing,
non-recessed, vented heater for furnishing warmed air to the space in
which it is installed. The vented room heater supplies heated air
circulated by gravity or by a fan directly into the space to be heated
through openings in the casing.
(4) ``Vented wall furnace'' means a self-contained vented heater
complete with grilles or the equivalent, designed for incorporation in,
or permanent attachment to, a wall of a residence and furnishing heated
air circulated by gravity or by a fan directly into the space to be
heated through openings in the casing.
(5) ``Unvented home heating equipment'' means a class of home
heating equipment, not including furnaces, used for the purpose of
furnishing heat to a space proximate to such heater directly from the
heater and without duct connections and includes electric heaters and
unvented gas and oil heaters.
Issue A.2 DOE requests comment on whether the definitions
applicable to DHE require any revisions, and if so, how those
definitions should be revised. Please provide a rationale for any
suggested change. DOE also requests feedback on whether the sub-
category definitions currently in place are appropriate or whether
further modifications are needed. If these sub-category definitions
need modifying, DOE seeks specific input on how to define these terms.
Issue A.3 DOE requests comment on whether additional product
definitions are necessary to close any potential gaps in coverage
between product types. DOE also seeks input on whether such products
currently exist in the market or whether they are being planned for
introduction.
B. Market and Technology Assessment
The market and technology assessment that DOE routinely conducts
when analyzing the impacts of a potential new or amended energy
conservation standard provides information about the DHE industry that
will be used in DOE's analysis throughout the rulemaking process. DOE
uses qualitative and quantitative information to characterize the
structure of the industry and market. DOE identifies manufacturers,
estimates market shares and trends, addresses regulatory and non-
regulatory initiatives intended to improve energy efficiency or reduce
energy consumption, and explores the potential for efficiency
improvements in the design and manufacturing of the subject products.
DOE also reviews product literature, industry publications, and company
websites, as well as information from trade journals, government
agencies, and trade organizations. Additionally, DOE routinely conducts
interviews with manufacturers to improve its assessment of the market
and available technologies for DHE.
1. Product Classes
When evaluating and establishing energy conservation standards, DOE
may divide covered products into product classes by the type of energy
used, or by capacity or other performance-related features that justify
a different standard. (42 U.S.C. 6295(q)) In making a determination
whether capacity or another performance-related feature justifies a
different standard, DOE must consider such factors as the utility of
the feature to the consumer and other factors DOE deems appropriate.
Id.
For DHE, the current energy conservation standards specified in 10
CFR 430.32(i)(2) are based on 11 product classes divided by equipment
type (i.e., wall, floor, or room), heat circulation type (i.e., fan or
gravity), and input capacity. Table II.1 lists the current product
classes for DHE.
Table II.1--Current Direct Heating Equipment Product Classes
------------------------------------------------------------------------

------------------------------------------------------------------------
Wall............... Fan..................... <=42,000.

>20,000 and <=27,000.
>27,000 and <=46,000.
>46,000.
------------------------------------------------------------------------
Issue B.1 DOE requests feedback on the current DHE product classes
and whether changes to these individual product classes and their
descriptions should be made or whether certain classes should be merged
or separated. DOE further requests feedback on whether combining
certain classes could impact product utility by eliminating any
performance-related features or impact the stringency of the current
energy conservation standard for these products. DOE also requests
comment on separating any of the existing product classes and whether
it would impact product utility by eliminating any performance-related
[[Page 6099]]
features or reduce any compliance burdens.
Issue B.2 DOE seeks information regarding any other new product
classes it should consider for inclusion in its analysis. Specifically,
DOE requests information on the performance-related features (e.g.,
input capacity, equipment type, heater type, etc.) that provide unique
consumer utility and data detailing the corresponding impacts on energy
use that would justify separate product classes (i.e., explanation for
why the presence of these performance-related features would increase
energy consumption).
2. Technology Assessment
In analyzing the feasibility of potential new or amended energy
conservation standards, DOE uses information about existing and past
technology options and prototype designs to help identify technologies
that manufacturers could use to meet and/or exceed a given set of
energy conservation standards under consideration. In consultation with
interested parties, DOE intends to develop a list of technologies to
consider in its analysis. That analysis will likely include a number of
the technology options DOE previously considered during its most recent
rulemaking for DHE. A complete list of those prior options appears in
Table II.2. DOE has conducted a preliminary review and did not identify
any new options.
---------------------------------------------------------------------------
\4\ See chapter 3, section 3.3.2.2 in the April 2010 final rule
technical support document (TSD) published during the rulemaking
process, document #149 on https://regulations.gov in docket ID EERE-
2006-STD-0129.

------------------------------------------------------------------------
Issue B.3 DOE seeks information on the technologies listed in Table
II.2 regarding their applicability to the current market and how these
technologies may impact the efficiency of DHE as measured according to
the DOE test procedure. DOE also seeks information on how these
technologies may have changed since they were considered in the October
2016 Final Determination analysis. Specifically, DOE seeks information
on the range of efficiencies or performance characteristics that are
currently available for each technology option.
Issue B.4 DOE seeks comment on other technology options that it
should consider for inclusion in its analysis. DOE is particularly
interested in information for any potential new technology options
regarding their market adoption, costs, and any concerns with
incorporating them into products (e.g., impacts on consumer utility,
potential safety concerns, manufacturing/production/implementation
issues).
C. Screening Analysis
The purpose of the screening analysis is to evaluate the
technologies that improve equipment efficiency to determine which
technologies will be eliminated from further consideration and which
will be passed to the engineering analysis for further consideration.
DOE determines whether to eliminate certain technology options from
further consideration based on the following criteria:
(1) Technological feasibility. Technologies that are not
incorporated in commercial products or in working prototypes will not
be considered further.
(2) Practicability to manufacture, install, and service. If it is
determined that mass production of a technology in commercial products
and reliable installation and servicing of the technology could not be
achieved on the scale necessary to serve the relevant market at the
time of the compliance date of the standard, then that technology will
not be considered further.
(3) Impacts on equipment utility or equipment availability. If a
technology is determined to have significant adverse impact on the
utility of the equipment for significant subgroups of consumers, or
result in the unavailability of any covered equipment type with
performance characteristics (including reliability), features, sizes,
capacities, and volumes that are substantially the same as equipment
generally available in the United States at the time, it will not be
considered further.
(4) Adverse impacts on health or safety. If it is determined that a
technology will have significant adverse impacts on health or safety,
it will not be considered further.
10 CFR part 430, subpart C, appendix A, sections 4(a)(4) and 5(b).
Technology options identified in the technology assessment are
evaluated against these criteria using DOE analyses and inputs from
interested parties (e.g., manufacturers, trade organizations, and
energy efficiency advocates). Technologies that pass through the
screening analysis are referred to as ``design options'' in the
engineering analysis. Technology options that fail to meet one or more
of the four criteria are eliminated from consideration.
Additionally, DOE notes that the four screening criteria do not
directly address the proprietary status of technology options. DOE only
considers potential efficiency levels achieved through the use of
proprietary designs in the engineering analysis if they are not part of
a unique pathway to achieve the efficiency level (i.e., if there are
other non-proprietary technologies capable of achieving the same
efficiency level).
Table II.3 summarizes the technology options that DOE screened out
in the April 2010 final rule, and the applicable screening criteria.

Issue C.1 DOE requests feedback on what impact, if any, the
screening criteria described in this section would have on each of the
technology options listed in Table II.2 with respect to DHE. Similarly,
DOE seeks information regarding how these same criteria would affect
any other technology options not already identified in this document
with respect to their potential use in DHE.
---------------------------------------------------------------------------
\5\ See chapter 4, section 4.2.2 in the April 2010 final rule
TSD published during the rulemaking process, document #149 on
https://regulations.gov in docket ID EERE-2006-STD-0129.
---------------------------------------------------------------------------
Issue C.2 With respect to the screened out technology options
listed in Table II.3, DOE seeks information on whether these options
should, based on current and projected assessments regarding each of
them, remain screened out under the screening criteria described in
this section. With respect to each of these technology options, what
steps, if any, could be (or have already been) taken to facilitate the
introduction of each option as a means to improve the energy
performance of DHE?
D. Engineering Analysis
The engineering analysis estimates the cost-efficiency relationship
of products at different levels of increased energy efficiency
(``efficiency levels''). This relationship serves as the basis for the
cost-benefit calculations for consumers, manufacturers, and the Nation.
In determining the cost-efficiency relationship, DOE estimates the
change in manufacturer production cost (``MPC'') associated with
increasing the efficiency of products above the baseline, up to the
maximum technologically feasible (``max-tech'') efficiency level for
each product class.
DOE historically has used the following three methodologies to
generate incremental manufacturing costs and establish efficiency
levels (``ELs'') for analysis: (1) The design-option approach, which
provides the incremental costs of adding to a baseline model design
options that will improve its efficiency; (2) the efficiency-level
approach, which provides the relative costs of achieving increases in
energy efficiency levels, without regard to the particular design
options used to achieve such increases; and (3) the cost-assessment (or
reverse engineering) approach, which provides ``bottom-up''
manufacturing cost assessments for achieving various levels of
increased efficiency, based on detailed cost data for parts and
material, labor, shipping/packaging, and investment for models that
operate at particular efficiency levels.
In the analysis for the April 2010 final rule, DOE analyzed four
product classes that were representative of the 11 total classes.
Specifically, for each type of DHE (i.e., wall fan, wall gravity,
floor, room), DOE selected one ``representative'' input range for
analysis and applied that analysis across all other input rate ranges
for the given type of DHE. DOE developed a cost-efficiency relationship
for each of these analyzed representative product classes that were
used as the input for the downstream analyses conducted in support of
that rulemaking. See chapter 5 of the April 2010 final rule TSD for the
cost-efficiency curves developed in that rulemaking.
Issue D.1 DOE requests comment on whether it is necessary to
individually analyze all 11 product classes, or whether the approach of
analyzing a representative sub-set of product classes is appropriate
for any potential future DHE energy conservation standards rulemaking.
For example, analysis on the gas wall fan less than or equal to 42,000
Btu/h product classes may not be necessary if the analysis on the
corresponding gas wall fan greater than 42,000 Btu/h product classes is
applicable to both product classes. Additionally, DOE welcomes comment
on potential approaches to apply the analyzed representative product
class results to the other product classes, including the approach used
for the April 2010 final rule. If it is necessary to individually
analyze each of the 11 product classes (or more than the 11 classes),
please provide information on why aggregating certain products is not
appropriate. If this approach is not appropriate, what alternative
approaches should DOE consider using and why? \6\
---------------------------------------------------------------------------
\6\ See chapter 5, section 5.3 in the April 2010 final rule TSD
published during the rulemaking process, document #149 on https://regulations.gov in docket ID EERE-2006-STD-0129.
---------------------------------------------------------------------------
1. Baseline Efficiency Levels
For each product class that is analyzed, DOE selects a baseline
model as a reference point against which any changes resulting from new
or amended energy conservation standards can be measured. The baseline
model in each product class represents the characteristics of common or
typical products in that class. Typically, a baseline model is one that
just meets the current minimum energy conservation standards and
provides basic consumer utility.
DOE uses baseline models for comparison in several phases of the
analyses, including the engineering analysis, life-cycle cost (``LCC'')
analysis, payback period (``PBP'') analysis, and national impact
analysis (``NIA''). In the engineering analysis, to determine the
changes in price to the consumer that result from amended standards,
DOE compares the price of a baseline model to the price of a model at
each higher efficiency level.
If it determines that a rulemaking is necessary, consistent with
this analytical approach, DOE tentatively plans to consider the current
minimum energy conservations standards (which went into effect April
16, 2013) to establish the baseline efficiency levels for each product
class. The current standards for each product class are based on DHE
type (wall, floor, or room), heat circulation type (fan or gravity),
and input capacity. The current standards for DHE are found at 10 CFR
430.32(i)(2).
Issue D.2 DOE requests feedback on whether using the current
established energy conservation standards for DHE are appropriate
baseline efficiency levels for DOE to apply to each product class in
evaluating whether to amend
[[Page 6101]]
the current energy conservation standards for these products. DOE
requests data and suggestions to evaluate the baseline efficiency
levels in order to better evaluate the potential for amending energy
conservation standards for these products.
Issue D.3 DOE requests feedback on the appropriate baseline
efficiency levels for any newly analyzed product classes that are not
currently in place or for any contemplated combined or separated
product classes, as discussed in section II.B.1 of this document. For
product classes that would be newly analyzed (if any), DOE requests
energy use data to develop a baseline relationship between energy use
and input capacity.
2. Maximum Available and Maximum Technologically Feasible Levels
As part of DOE's analysis when considering potential amended
standards, DOE determines the maximum available efficiency level and
the maximum technologically feasible (``max-tech'') efficiency level
for each product class analyzed. The maximum available efficiency level
is the highest-efficiency model currently available on the market for
that class. The max-tech efficiency level represents the theoretical
maximum possible efficiency if all available design options are
incorporated in a model. In some cases, models at the max-tech
efficiency level are not commercially available because, although the
level is technically achievable, manufacturers have determined that it
is not economically feasible (either for the manufacturer to produce or
for consumers to purchase). However, DOE seeks to determine the max-
tech level for purposes of its analyses. The current maximum available
efficiencies for the 11 existing product classes are included in Table
II.4, along with the maximum available efficiencies from the April 2010
final rule and the October 2016 final determination.

[dagger] Representative product classes analyzed in the April 2010 final rule.
In the April 2010 final rule, DOE determined max-tech efficiency
levels using the technology options available at that time. For gas
wall fan DHE with an input rate over 42,000 Btu/h, DOE identified a
max-tech efficiency level design with induced draft combustion,
resulting in an AFUE of 80 percent. For gas wall gravity DHE with an
input rate over 27,000 Btu/h and up to 46,000 Btu/h, DOE identified 70
percent AFUE as a theoretical max-tech level, which was achievable with
an improved heat exchanger design and electronic ignition. For gas
floor DHE with an input rate over 37,000 Btu/h, DOE identified the max-
tech efficiency level as 58 percent AFUE, which DOE stated could be
reached using an improved heat exchanger design. For gas room DHE with
an input rate over 27,000 Btu/h and up to 46,000 Btu/h, DOE identified
a theoretical max-tech efficiency level of 83 percent AFUE, which
manufacturers could achieve using an electronic ignition and improved
heat exchanger. 75 FR 20112, 20145-20146 (April 16, 2010).
In the October 2016 final determination, DOE noted that condensing
gas wall fan DHE models with input rates at or below 42,000 Btu/h had
become available, and DOE considered this the max-tech level for gas
wall fan DHE. Based on information obtained during manufacturer
interviews and a manufacturer production cost found through a teardown
analysis performed for the proposed determination (81 FR 21276, 21280
(April 11, 2016)), DOE determined that condensing technology was not
economically justified for gas wall fan DHE at that time. 81 FR 71325,
71328 (Oct. 17, 2016). During manufacturer interviews conducted leading
up to the proposed determination, manufacturers indicated that
condensing models are significantly more expensive to produce than non-
condensing models, which DOE confirmed through its teardown analysis,
which showed a 23 percent manufacturing cost increase for condensing
units. Manufacturers also indicated that shipments were so low as to be
negligible, and DOE noted that only one manufacturer produced a
condensing gas wall fan DHE at that time. DOE stated in the final
determination that manufacturers would need to make substantial
investments in order to produce these units on a scale large enough to
support a Federal minimum standard and that severe manufacturer impacts
would be expected if an energy conservation standard were adopted at a
level met through use of condensing technology. Therefore, DOE
concluded the condensing technology option would not be economically
justified at that time when analyzed for the Nation as a whole. Id. In
DOE's preliminary research for this RFI, it found that 2 out of the 4
manufacturers of gas wall fan DHE currently make products incorporating
condensing technology.
Issue D.4 DOE seeks input on whether the maximum available
[[Page 6102]]
efficiency levels are appropriate and technologically feasible for
consideration as possible energy conservation standards for the
products at issue, and if not, why not. DOE also seeks input on whether
other maximum efficiency levels are possible with technologies, or
combinations of technologies, not currently incorporated in available
designs.
Issue D.5 DOE seeks feedback on what design options would be
incorporated at a max-tech efficiency level, and the efficiencies
associated with those levels. As part of this request, DOE also seeks
information as to whether there are limitations on the use of certain
combinations of design options.
3. Manufacturer Production Costs and Manufacturing Selling Price
As described at the beginning of this section, the main outputs of
the engineering analysis are cost-efficiency relationships that
describe the estimated increases in manufacturer production cost (MPC)
associated with higher-efficiency products for the analyzed product
classes. For the April 2010 final rule, DOE developed the cost-
efficiency relationships by estimating the efficiency improvements and
costs associated with incorporating specific design options into the
assumed baseline model for each analyzed product class. 75 FR 20112,
20147-20149 (April 16, 2010).
Issue D.6 DOE requests feedback on how manufacturers would
incorporate the technology options listed in Table II.2 to increase
energy efficiency in DHE beyond the baseline. This includes information
on the order in which manufacturers would incorporate the different
technologies to incrementally improve the efficiencies of products. DOE
also requests feedback on whether the increased energy efficiency would
lead to other design changes that would not occur otherwise. DOE is
also interested in information regarding any potential impact of design
options on a manufacturer's ability to incorporate additional functions
or attributes in response to consumer demand.
Issue D.7 DOE also seeks input on the change in MPC associated with
incorporating each particular design option. Specifically, DOE is
interested in whether and how the costs estimated for design options in
the April 2010 final rule have changed since the time of that analysis.
DOE also requests information on the investments necessary to
incorporate specific design options, including, but not limited to,
costs related to new or modified tooling (if any), materials,
engineering, and development efforts to implement each design option,
and manufacturing/production impacts.
Issue D.8 DOE requests comment on whether certain design options
may not be applicable to (or incompatible with) specific product
classes.
To account for manufacturers' non-production costs and profit
margin, DOE applies a non-production cost multiplier (the manufacturer
mark-up) to the MPC. The resulting manufacturer selling price (``MSP'')
is the price at which the manufacturer distributes a unit into
commerce. For the April 2010 final rule, DOE used a manufacturer mark-
up of 1.35 for all DHE. See chapter 5 of the April 2010 final rule TSD.
Issue D.9 DOE requests feedback on whether a manufacturer mark-up
of 1.35 is appropriate for all DHE.
E. Mark-Up Analysis
The mark-ups analysis develops appropriate mark-ups (e.g., for
wholesalers, mechanical contractors, general contractors) in the
distribution chain (i.e., how the products are distributed from the
manufacturer to the consumer) and sales taxes to convert the
manufacturer sales prices (``MSP'') derived in the engineering analysis
to consumer prices, which are then used in the LCC and PBP analyses and
other analyses. At each step in the distribution channel, companies
mark up the price of the equipment to cover business costs and profit
margin.
1. Distribution Channels
In generating end-user price inputs for the LCC analysis and NIA,
DOE must identify distribution channels (i.e., how the products are
distributed from the manufacturer to the consumer) and estimate
relative sales volumes through each channel. Two different markets
exist for DHE: (1) Replacements and new owners,\7\ and (2) new
construction. DOE intends to use similar distribution channels in its
analysis as found in the April 2010 final rule. DHE is mainly a
replacement product.\8\ For replacement and new owner applications,
most sales go through distributors to contractors, and then to
consumers as follows:
---------------------------------------------------------------------------
\7\ New owners are defined as existing buildings that acquire a
DHE for the first time during the analysis period. An example of new
owner for DHE would be someone with an addition to an existing house
where it would not be feasible to extend the house's primary heating
system to the new space.
\8\ The Air-Conditioning, Heating, and Refrigeration Institute
(AHRI) stated that less than 5 percent of DHE sales are for new
construction projects. AHRI, Comment #7 for RFI for Energy
Conservation Standards for Energy Conservation Standards for Direct
Heating Equipment and Pool Heaters (April 27, 2015) (Available at:

(Last accessed Oct. 2, 2018).
Manufacturer [rarr] Wholesaler [rarr] Mechanical Contractor [rarr]
---------------------------------------------------------------------------
Consumer
In new home applications, most sales go through distributors to
contractors hired by the builder as follows:
Manufacturer [rarr] Wholesaler [rarr] Mechanical Contractor [rarr]
General Contractor [rarr] Consumer
Issue E.1 DOE requests information on the existence of any
distribution channels that are used to distribute the products at issue
into the market. DOE also requests data on the fraction of DHE sales in
the residential sector that go through any identified channels.
2. Mark-Ups
To develop mark-ups for the parties involved in the distribution of
the equipment, DOE plans to primarily utilize: (1) The Heating, Air
Conditioning & Refrigeration Distributors International (``HARDI'')
2013 Profit Report \9\ (for wholesalers) and 3. U.S. Census Bureau 2012
Economic Census data \10\ on the residential building construction
industry (for general contractors and mechanical contractors). DOE also
plans to use the 2005 Air Conditioning Contractors of America's
(``ACCA'') Financial Analysis on the Heating, Ventilation, Air-
Conditioning, and Refrigeration (``HVACR'') contracting industry \11\
to disaggregate the mechanical contractor mark-ups into replacement and
new construction markets. DOE will also consider updates to any of
these materials that may publish during DOE's evaluation.

In addition to the mark-ups, DOE will derive State and local taxes
from data provided by the Sales Tax Clearinghouse.\12\ These data

considered in the analysis.

Issue E.2 DOE requests recent data and recommendations regarding
data sources to establish the mark-ups for the
[[Page 6103]]
parties involved with the distribution of DHE.
F. Energy Use Analysis
DOE conducts an energy use analysis to identify how products are
used by consumers, and thereby determine the energy savings potential
of energy efficiency improvements. DOE uses the annual energy
consumption and energy-savings potential in the LCC and PBP analysis to
establish the operating costs savings at various product efficiency
levels. DOE will estimate the annual energy consumption of direct
heating equipment at specified energy efficiency levels across a range
of applications, household types, and climate zones. The annual energy
consumption includes use of natural gas, liquefied petroleum gas (LPG
(i.e., propane)), and electricity.
1. Sample Development
DOE intends to base the energy use analysis on key characteristics
from the Energy Information Administration's (``EIA'') 2015 Residential
Energy Consumption Survey (``RECS'') \13\ for the subset of residential
buildings that use DHEs. DOE also plans to include in its analysis DHE
used in the commercial sector using EIA's 2012 Commercial Building
Energy Consumption Survey (``CBECS'').\14\

Building Energy Consumption Survey (CBECS) (Available at: http://www.eia.gov/consumption/commercial/) (Last accessed Oct. 2, 2018).
---------------------------------------------------------------------------
RECS and CBECS data include information on the DHE type, physical
characteristics of buildings, fuels used, energy consumption and
expenditures, and other relevant characteristics.\15\ Based on RECS
2015 and CBECS 2012 data, DOE will develop a representative population
of buildings for DHE. In addition, DOE intends to review other data
sets (e.g., data from the 2016 Residential Building Stock Assessment
for the Northwest,\16\ 2014 Commercial Building Stock Assessment for
the Northwest,\17\ 2015 Residential Statewide Baseline Study of New
York State,\18\ 2006 California Commercial End-Use Survey,\19\ and 2009
Residential Appliance Saturation Study \20\) to compare these to the
RECS 2015 and CBECS 2012 data for the corresponding region.
---------------------------------------------------------------------------
\15\ From RECS 2015, DOE intends to use households listed as
using primary gas heating equipment from ``built-in room heater
burning gas, oil, or kerosene'' (138 home sample is estimated to
represent 2.8 million homes in 2015) and ``built-in floor/wall
pipeless furnace'' (41 home sample is estimated to represent 0.8
million homes in 2015) and as secondary gas heating equipment from
``some other equipment'' (221 home sample is estimated to represent
4.2 million homes in 2015).

---------------------------------------------------------------------------
Issue F.1 DOE requests comment on the overall method to determine
the building sample for direct heating equipment and whether other
factors should be considered in developing the building sample. In
addition, DOE requests information on the installation applications of
DHE, including, but not limited to the fraction of DHEs that are
installed in residential and commercial applications, as well as how
many DHE are typically installed per building.
2. Energy Use Calculations
To determine the site energy consumption by the DHEs installed in
the building, DOE intends to use a methodology based on the energy use
equations from the DOE test procedure for DHEs (10 CFR part 430,
subpart B, appendix O, section 4.6). For each household or building in
the sample, DOE plans to use RECS 2015 and CBECS 2012 reported heating
energy consumption to estimate the heating load of the housing unit or
building.\21\ The estimation of heating loads requires data on the
existing DHE characteristics (such as DHE type, fuel type, equipment
size, and efficiency of the DHE). DOE intends to assign DHE
characteristics of existing systems based on the distributions of DHE
provided in historical versions of the AHRI model certification
directory \22\ and any other available historical data. The estimation
of heating loads also requires calculating the electricity consumption
of the blower (when applicable), because heat from the blower
contributes to heating the housing unit. A large fraction of DHE are
used as secondary heating equipment; therefore, DOE intends to adjust
the house heating load for households that use the direct heating
equipment as secondary heating equipment by using the reported fraction
of heating energy consumption attributable to secondary heating
products in RECS 2015. To complete the analysis, DOE plans to calculate
the energy consumption of more energy efficient DHE alternatives
replacing the existing DHE.
---------------------------------------------------------------------------
\21\ The heating load represents the amount of heating required
to keep a housing unit comfortable throughout an average year.

---------------------------------------------------------------------------
Issue F.2 DOE requests comment on the overall method to determine
energy use of direct heating equipment and if other factors should be
considered in developing the energy use methodology.
G. Life-Cycle Cost and Payback Period Analysis
DOE plans to conduct LCC and PBP analyses to evaluate the economic
impacts on residential and commercial consumers of potential standards
for DHEs. The effect of new or amended standards on residential and
commercial consumers usually involves a reduction in operating cost and
an increase in purchase cost.
DOE intends to analyze the potential for variability by performing
the LCC and PBP calculations on a representative sample of residential
and commercial consumers. DOE plans to utilize the sample of buildings
developed for the energy use analysis. DOE plans to model uncertainty
in many of the inputs to the LCC and PBP analysis using Monte Carlo
simulation and probability distributions. As a result, the LCC and PBP
results will be presented as distributions of impacts compared to the
no-new-standards case (i.e., the case without amended standards).
Inputs to the LCC and PBP analysis are categorized as: (1) Inputs
for establishing the purchase expense, otherwise known as the total
installed cost, and (2) inputs for calculating the operating costs.
Each type of input is discussed in the paragraphs that follow.
1. Total Installed Cost
The primary inputs for establishing the total installed cost are
the baseline customer price, incremental customer price increases
resulting from a potential standard, and installation costs. Baseline
prices and standard-level price increases will be determined by
applying mark-ups to manufacturer selling price estimates and sales
tax.
The installation cost is added to the customer price to arrive at a
total
[[Page 6104]]
installed cost. DOE intends to develop installation costs using the
most recent RS Means data available.\23\ DOE also intends to use
regional labor costs to more accurately estimate installation costs by
applying the appropriate regional labor cost from RS Means to each
sampled DHE installation.
---------------------------------------------------------------------------
\23\ RS Means, 2018 Mechanical Cost Data (Available at: https://www.rsmeans.com/products/books.aspx) (Last accessed Oct. 2, 2018).
---------------------------------------------------------------------------
In conducting its analyses, DOE intends to utilize an installation
cost methodology that is customized for each DHE product class. For
DHEs in new owner installations or new construction, DOE plans to
include costs such as adding gas piping, putting the DHE in place, and
additional set-up. For replacement cases, in addition to the costs
considered for new installations, DOE also plans to include the
installation cost associated with disconnecting and removing the old
DHE, as well as removal/disposal and permit fees, if applicable. In
addition, DOE intends to assess whether installation costs vary with
equipment efficiency, including design options that require a new
electrical outlet (many existing DHE installations currently do not
have electrical power input) or condensing DHE units that require new
PVC venting and condensate withdrawal.
Issue G.1 DOE seeks input on any available installation cost data
for DHEs. DOE also seeks input on the approach it intends to use to
develop DHE installation costs, specifically, its intention to use the
most recent RS Means Mechanical Cost Data.
2. Operating Costs
The primary inputs for calculating the operating costs of DHEs are
energy consumption, equipment efficiency, energy prices, maintenance
and repair costs, equipment lifetime, and discount rates. Both
equipment lifetime and discount rates are used to calculate the present
value of future operating costs.
The product energy consumption is the site energy use associated
with providing space heating to the room of a building. DOE intends to
utilize the site energy use calculation methodology described in
section II.F of this document to determine product energy use. DOE also
plans to assess the potential applicability of the ``rebound effect''
in the energy consumption for DHE. A rebound effect occurs when a
product that is made more efficient is used more intensively, so that
the expected energy savings from the efficiency improvement may not
fully materialize. However, at this time, DOE is not aware of any
information about a rebound effect for DHE.
Issue G.2 DOE seeks comments and data on any rebound effect that
may be associated with more-efficient DHE.
The repair cost is the expense to repair or replace components of
the covered product that have failed. The maintenance cost is the
expense of regular scheduled product maintenance to ensure the
continued operation of the covered product over time. These costs cover
all labor and material costs associated with the repair or maintenance.
DOE intends to develop repair and maintenance costs using the most
recent RS Means data available \24\ and manufacturer literature.
---------------------------------------------------------------------------
\24\ RS Means, 2018 Facilities Maintenance & Repair Cost Data
(Available at: https://www.rsmeans.com/products/books.aspx) (Last
accessed Oct. 2, 2018).
---------------------------------------------------------------------------
DOE intends to assess whether repair or maintenance costs vary with
equipment efficiency and product class. In addition, DOE plans to
consider the cases in which the equipment is covered by warranty,
service, and/or maintenance agreements. More specifically, DOE intends
to account for the maintenance cost associated with the manufacturer-
recommended annual maintenance prior to the heating season.
DOE will determine the repair cost using an approach that reflects
the cost and the service life of the components that are likely to
fail. DOE plans to consider component repair costs that might fail
during the lifetime of the product, including the pilot ignition,
electronic ignition, circulating blower, and induced draft fan.
Issue G.3 DOE requests feedback and data on whether maintenance
costs differ in comparison to the baseline maintenance costs for any of
the specific technology options listed in Table II.2 and Table II.3. To
the extent that these costs differ, DOE seeks supporting data and the
reasons for those differences.
Issue G.4 DOE requests information and data on the frequency of
repair and repair costs by product class for the technology options
listed in Table II.2 and Table II.3. DOE is also interested in whether
consumers simply replace the products when they fail as opposed to
repairing them.
Issue G.5 DOE also seeks comment on the extent to which repair or
maintenance costs are covered by warranty, service, and/or maintenance
agreements.
Equipment lifetime is the age at which a unit is retired from
service. DOE intends to conduct a literature review of DHE lifetime
data together with any stakeholder lifetime data to develop a Weibull
probability distribution to characterize DHE lifetime.\25\
---------------------------------------------------------------------------
\25\ A Weibull probability distribution is a continuous
distribution function typically used in reliability engineering and
equipment failure analysis. If the data are available, DOE also
plans to take into account differences in DHE lifetime based on
usage and application.
---------------------------------------------------------------------------
Issue G.6 DOE requests product lifetime data and information on
whether product lifetime varies based on DHE product class,
application, or efficiency.
DOE measures LCC and PBP impacts of potential standard levels
relative to a no-new-standards case that reflects the likely market in
the absence of amended standards. DOE plans to develop efficiency
market shares (i.e., the distribution of product shipments by
efficiency) for DHEs, for the anticipated year in which compliance with
any potential amended standards would be required. DOE is not aware of
any shipment data to estimate the market shares of different DHE energy
efficiency levels in the no-new-standards case. DOE is particularly
interested in receiving such data. If no market share data become
available, DOE intends to use data on the number of DHE models at
different energy efficiency levels, as reported in DOE's compliance
certification database,\26\ historical versions of the AHRI model
certification directory,\27\ and from manufacturer literature.

Issue G.7 DOE requests information on the DHE market, including but
not limited to, the current market share by different efficiency level
and by product class, similar historical data, and information on
expected future trends in the efficiency of DHEs.
H. Shipments Analysis
DOE develops shipments forecasts of DHE to calculate the national
impacts of potential amended energy conservation standards on energy
consumption, net present value (``NPV''), and future manufacturer cash
flows. DOE shipments projections are based on available historical data
broken out by product class, input capacity, and efficiency. Current
sales estimates allow for a more accurate model that captures recent
trends in the market. From the April 2010 final rule, DOE has DHE
historical shipment data from AHRI for
[[Page 6105]]
wall furnaces from 1990 to 1998 and from 2000 to 2006, for floor
furnaces from 1990 to 2007, and for room heaters from 1990 to 2005.\28

I. Manufacturer Impact Analysis
The purpose of the manufacturer impact analysis (``MIA'') is to
estimate the financial impact of new or amended energy conservation
standards on manufacturers of DHE, and to evaluate the potential impact
of such standards on direct employment and manufacturing capacity. The
MIA includes both quantitative and qualitative aspects. The
quantitative part of the MIA primarily relies on the Government
Regulatory Impact Model (``GRIM''), an industry cash-flow model adapted
for each product in this analysis, with the key output being the
industry net present value (``INPV''), which is used to assess the
financial impacts of a potential standard. The qualitative part of the
MIA addresses the potential impacts of energy conservation standards on
manufacturing capacity and industry competition, as well as factors
such as product characteristics, impacts on particular subgroups of
firms, and important market and product trends.
As part of the MIA, DOE intends to analyze impacts of potential
amended energy conservation standards on subgroups of manufacturers of
covered products, including small business manufacturers. DOE uses the
Small Business Administration's (``SBA'') small business size standards
to determine whether manufacturers qualify as small businesses, which
are listed by the applicable North American Industry Classification
System (``NAICS'') code.\31\ Manufacturing of consumer DHE is
classified under NAICS 333414, ``Heating Equipment (except Warm Air
Furnaces) Manufacturing,'' and the SBA sets a threshold of 500
employees or less for a domestic entity to be considered as a small
business. This employee threshold includes all employees in a
business's parent company and any other subsidiaries.
---------------------------------------------------------------------------
\31\ Available online at: http://www.sba.gov/sites/default/files/Size_Standards_Table.pdf.
---------------------------------------------------------------------------
One aspect of assessing manufacturer burden involves examining the
cumulative impact of multiple DOE standards and the product-specific
regulatory actions of other Federal agencies that affect the
manufacturers of a covered product or equipment. While any one
regulation may not impose a significant burden on manufacturers, the
combined effects of several existing or impending regulations may have
serious consequences for some manufacturers, groups of manufacturers,
or an entire industry. Assessing the impact of a single regulation may
overlook this cumulative regulatory burden. In addition to energy
conservation standards, other regulations can significantly affect
manufacturers' financial operations. Multiple regulations affecting the
same manufacturer can strain profits and lead companies to abandon
product lines or markets with lower expected future returns than
competing products. For these reasons, DOE conducts an analysis of
cumulative regulatory burden as part of its rulemakings pertaining to
appliance efficiency.
Issue I.1 To the extent feasible, DOE seeks the names and contact
information of any domestic or foreign-based manufacturers that
distribute DHE in the United States.
Issue I.2 DOE identified small businesses as a subgroup of
manufacturers that could be disproportionally impacted by amended
energy conservation standards. DOE requests the names and contact
information of small business manufacturers, as defined by the SBA's
size threshold, that distribute DHE products in commerce in the United
States. In addition, DOE requests comment on any other manufacturer
subgroups that could be disproportionally impacted by amended energy
conservation standards for DHE. DOE requests feedback on any potential
approaches that could be considered to address impacts on
manufacturers, including small businesses.
[[Page 6106]]
Issue I.3 DOE requests information regarding the cumulative
regulatory burden impacts on manufacturers of DHE associated with: (1)
Other DOE standards applying to different products that these
manufacturers may also make and (2) product-specific regulatory actions
of other Federal agencies. DOE also requests comment on its methodology
for computing cumulative regulatory burden and whether there are any
flexibilities it can consider that would reduce this burden while
remaining consistent with the requirements of EPCA.
J. Other Energy Conservation Standards Topics
1. Market Failures
In the field of economics, a market failure is a situation in which
the market outcome does not maximize societal welfare. Such an outcome
would result in unrealized potential welfare. DOE welcomes comment on
any aspect of market failures, especially those in the context of
amended energy conservation standards for DHE.
2. Market-Based Approaches to Energy Conservation Standards
As part of its regulatory reform efforts, DOE published a request
for information discussing key issues and requesting feedback on
market-based approaches to energy conservation standards. 82 FR 56181
(Nov. 28, 2017). DOE requests comment on how market-based approaches to
energy conservation standards might impact standards for these
products, and specifically seeks comment on any considerations with
respect to DHE.
In addition to the issues identified earlier in this document, DOE
welcomes comment on any other aspect of energy conservation standards
for DHE not already addressed by the specific areas identified in this
document.
