As defined in the Code of Federal Regulations (CFR), “consumer water heater” means a product which utilizes oil, gas, or electricity to heat potable water for use outside the heater upon demand, including — (1) Storage type units which heat and store water at a thermostatically controlled temperature, including gas storage water heaters with an input of 75,000 Btu per hour or less, oil storage water heaters with an input of 105,000 Btu per hour or less, and electric storage water heaters with an input of 12 kilowatts or less; (2) Instantaneous type units that heat water but contain no more than one gallon of water per 4,000 Btu per hour of input, including gas instantaneous water heaters with an input of 200,000 Btu per hour or less, oil instantaneous water heaters with an input of 210,000 Btu per hour or less, and electric instantaneous water heaters with an input of 12 kilowatts or less; and (3) Heat pump type units, with a maximum current rating of 24 amperes at a voltage no greater than 250 volts, which are products designed to transfer thermal energy from one temperature level to a higher temperature level for the purpose of heating water, including all ancillary equipment such as fans, storage tanks, pumps, or controls necessary for the device to perform its function. 10 CFR 430.2 Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for consumer water heaters since 1990.
DOE has issued a pre-publication final rule pertaining to energy conservation standards for consumer water heaters. 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 multiple product classes of consumer water heaters. 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 60 days after the notice has been published in the Federal Register.
- Compliance with the amended standards established in this final rule is required on and after 5 years after the notice has been published in the Federal Register.
For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change.

Consumer water heaters 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(d).
To determine that consumer water heaters that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at Appendix E to Subpart B of Part 430 – Uniform Test Method for Measuring the Energy Consumption of Water Heaters.
Compliance
DOE has established regulations on certification, compliance, and enforcement in the CFR at 10 CFR Part 429.These regulations cover statistical sampling plans, certified ratings, certification reports, record retention, and enforcement. More information on these regulations is available here.
Waivers
For information on current test procedure waivers, see DOE’s Waivers webpage.
For information about obtaining test procedure waivers, see 10 CFR 430.27.
Exceptions
DOE's Office of Hearings and Appeals has not authorized exception relief for consumer water heaters.
For information about obtaining exception relief, see 10 CFR part 1003.
Guidance and Frequently Asked Questions
For information on further guidance and answers to frequently asked questions on all covered products, see DOE’s Further Guidance database.
State Exemptions to Federal Pre-emption
DOE has not exempted any state from this energy conservation standard. States may petition DOE to exempt a state regulation from preemption by the federal energy conservation standard. States may also petition DOE to withdraw such exemptions. For details, see 10 CFR part 430, subpart D.
Small Business Exemptions
Any manufacturer of a covered product with annual gross revenues that do not exceed $8,000,000 from all its operations and meets certain other conditions may apply for an exemption to the energy conservation standard. For details, see 10 CFR part 430, subpart E.
ENERGY STAR®
DOE supports the testing and verification of ENERGY STAR products in close collaboration with the Environmental Protection Agency.
