1 Introduction
8

Regulatory History

• The Energy Policy and Conservation Act (EPCA) of 1975 

(Public Law 94-163)

– Established the Energy Conservation Program for 

consumer products other than automobiles, which 

includes direct heating equipment and pool heaters

– Directs DOE to establish test procedures in conjunction 

with energy conservation standards.

– Subsequent amendments to EPCA require the Secretary 

to review periodically all test procedures for possible 

amendment. (42 U.S.C. 6293 (b))

• The Energy Independence and Security Act of 2007 

(EISA 2007) (Public Law 110-140) 

• Directed DOE to develop, if necessary, a test procedure 

amendment to measure and incorporate standby mode 

and off mode energy consumption into all test 

procedures (42 U.S.C. 6295(gg)(2))
9

Regulatory History

• On May 12, 1997, DOE published a final rule in the Federal Register

establishing the current test procedures for direct heating equipment (DHE) 

and pool heaters. 62 FR 26140.

• The current test procedure for vented home heating equipment is found in 

Appendix O to Subpart B of 10 CFR Part 430 and applies to DHE.

• The current test procedure for pool heaters is found in Appendix P to 

Subpart B of 10 CFR Part 430.

• On December 17, 2012, DOE published in the Federal Register a final rule 

establishing a method for measuring the electrical energy use of DHE and 

pool heaters in standby mode and off mode. 75 FR 74559.

• On October 12, 2011, DOE published a request for information (RFI) on the 

need to amend the test procedures for DHE and pool heaters. 76 FR 63211.

1 Introduction
13

Summary of Proposed Updates: Direct Heating Equipment

• Adds provisions for testing vented home heating equipment 

that utilizes condensing technologies;

• Replaces outdated references to industry standards with 

references to six current industry test standards that do not 

substantively modify test set-up or conditions;

• Reduces the test burden for floor furnaces by allowing a default 

assigned value for jacket loss in lieu of testing; and

• Includes clarifications and corrections.
14

Provisions for Condensing Technologies

• Method to determine the efficiency of vented heaters that 

utilize condensing technologies

– Proposes using provisions similar to those found in DOE’s furnace and boiler test 

procedures.

– Would incorporate the method for testing condensing products from ASHRAE 

103-2007 “Method of Testing for Annual Fuel Utilization Efficiency of Residential 

Central Furnaces and Boilers” as stand-alone amendments to DOE’s vented 

heater test procedure.

• A separate test is conducted where condensate from the combustion 

process is directly collected and measured.

• For testing of condensing units that are not designed to collect and dispose 

of condensate in normal use, such means must be provided during testing.

• Using the measured condensate result, a reduction in the latent heat loss 

term (LL,A) is calculated to reflect the deserved efficiency increase. 

• The provisions would apply to all types of direct heating equipment. 
15

Updates of Industry Reference Standards

• Updates to referenced industry test standards

– Current test procedure references various industry standards that have 

been superseded and are no longer current. 

– DOE proposes to adopt six current industry standards. 

• In several cases, the proposed changes reflect the updating of specific 

provisions of the old standards to essentially identical provisions contained 

in the most current version of these standards. 

• In one case, the separate references for gas floor furnaces, gas wall furnaces, 

and gas room heaters are replaced with ANSI Z21.86-2008, which covers all 

three types of vented heaters. 

• ANSI/ASHRAE Standard 103-2007 is proposed for use in lieu of three older 

standards. 
16

Jacket Loss and Clarifications & Corrections

• Jacket loss

− To reduce testing burden, NOPR proposes that an assigned default value 

of 1 percent for jacket loss be optionally used in lieu of jacket loss testing 

for floor furnaces. This value is identical to the allowance for furnaces 

and boilers. 

• Clarifications and corrections

− Proposes that an equation be added to section 4.2.4 to provide a means 

of calculating a weighted-average steady-state efficiency for manually 

controlled vented heaters. 

− Proposes that the tracer gas procedures in section 3.3 be modified to 

make it clear how to test units not employing a thermal stack damper. 

− Proposes to correct typographical errors in section 4.3.6 in an equation 

to compute part-load fuel utilization efficiency. 

 
17

Issues on which DOE seeks comment: Direct Heating Equipment

Item 1: Are the proposed provisions for testing vented heaters that are capable 

of condensing operation appropriate and sufficient?

Item 2: Are the updates to the industry standards incorporated by reference 

into the direct heating equipment test procedure appropriate and sufficient?

 

Item 3: Is the assignment of a 1-percent default jacket loss in lieu of testing for 

vented floor furnaces appropriate? 

Item 4: What are the anticipated impacts of this proposed rule on small 

business manufacturers of direct heating equipment? 
18

Summary of Proposed Updates: Pool Heaters

Proposed expansion to cover electric pool heaters

– Would include both electric heat pump pool heaters and electric 

resistance heaters

Proposed clarification for oil-fired pool heaters

– The proposed amendments clarify that the test procedure also applies to 

oil-fueled pool heaters. 

– No changes to test procedure are required for this clarification. 
19

Coverage of Electric Pool Heaters

• Proposed expansion of test procedure to cover electric pool 

heaters 

– Proposed amendments for heat pump type electric pool heaters would 

reference ANSI/ASHRAE Standard 1160-2009, “Performance Rating of 

Heat Pump Pool Heaters” and ANSI/ASHRAE Standard 146-2011, 

“Method of Testing and Rating Pool Heaters”

– Proposed amendments for electric resistance type pool heaters would 

reference ANSI/ASHRAE Standard 146 -2011, “Method of Testing and 

Rating Pool Heaters”

– Proposed amendments would include additional calculations to 

determine integrated thermal efficiency, expressed in terms of percent, 

for all types of pool heaters.

– DOE is proposing to include a method to determine the integrated 

thermal efficiency based on the COP value for heat pump pool heaters.
20

Issues on which DOE seeks comment: Pool Heaters

Item 5: Are the proposed provisions for testing electric resistance and heat 

pump pool heaters appropriate and sufficient?

Item 6: What are the anticipated impacts of this proposed rule on small 

business manufacturers of pool heaters?
