Consumer Furnaces
As defined in the Code of Federal Regulations (CFR),”furnace” means a product which utilizes only single-phase electric current, or single-phase electric current or DC current in conjunction with natural gas, propane, or home heating oil, and which (1) Is designed to be the principal heating source for the living space of a residence; (2) Is not contained within the same cabinet with a central air conditioner whose rated cooling capacity is above 65,000 Btu per hour; (3) Is an electric central furnace, electric boiler, forced-air central furnace, gravity central furnace, or low-pressure steam or hot water boiler; and (4) Has a heat input rate of less than 300,000 Btu per hour for electric boilers and low-pressure steam or hot water boilers and less than 225,000 Btu per hour for forced-air central furnaces, gravity central furnaces, and electric central furnaces. 10 CFR 430.2 Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for residential mobile home gas furnaces since 1990 and for all other residential furnaces since 1992.

Recent and Ongoing Activities
DOE has published a Federal Register notice pertaining to energy conservation standards for consumer furnaces. The Energy Policy and Conservation Act (EPCA) requires DOE to determine periodically whether more stringent standards would be technologically feasible and economically justified, and would result in significant energy savings. In this final rule, DOE is adopting amended standards for consumer furnaces, specifically non-weatherized gas furnaces and mobile home gas furnaces. DOE has determined that the amended standards for the subject products would result in significant conservation of energy, and are technologically feasible and economically justified.
- The effective date of this rule is February 16, 2024.
- Compliance with the amended standards established for the subject consumer furnaces in this final rule is required on and after December 18, 2028.

Current Standard
Residential furnaces manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations at 10 CFR 430.32.
To determine that residential furnaces that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at 10 CFR 430.23.
