## 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 p ool h eaters 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 p ool h eaters. 76 FR 63211.10

Description of Issues Addressed in This NOPR Closing Remarks 4

## 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• Replaces outdated references to industry standards with references to six current industry test standards that do not substantively modify test set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 conde nsate from the combustion process is directly collected and measured.

• F or 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 (L L,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?21
