Whether gas or oil, ENERGY STAR qualified boilers use about 10% less energy than a standard boil
Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of Energy.
- ENERGY STAR qualified boilers have an annual fuel utilization efficiency (AFUE) rating of 85% or greater.
- They achieve greater efficiency with improved features, including:
- electric ignition, which eliminates the need to have the pilot light burning all the time
- new combustion technologies that extract more heat from the same amount of fuel
- sealed combustion that uses outside air to fuel the burner, reducing draft and improving safety
Remember, saving energy prevents pollution.
By choosing ENERGY STAR and taking steps to optimize the performance of your heating equipment, you are helping to prevent global warming and promoting cleaner air while enhancing the comfort of your home.
You may also be interested to know:
- Though these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills.
- When buying new equipment, sizing and installation are as important as product quality. See our recommendations for finding a good contractor.
- You can get better heating and cooling performance at home with ENERGY STAR home sealing (insulation and air sealing) and duct sealing.
- Consider regular maintenance to maintain your heating and cooling system performance.
Boilers Information Resources
Residential vs. Non-Residential Boilers
Residential: models with energy input less than 300,000 Btuh, and that use a single-phase electric supply. Minimum efficiency levels for this equipment are established by the National Appliance Energy Conservation Act (NAECA). The energy-efficiency metric for residential models is: Annual Fuel Utilization Efficiency (AFUE).
Non-residential: models with energy input equal to or greater than 300,000 Btuh that use a single-phase electric supply, and all models that require a three-phase electric supply. Minimum efficiency levels for this equipment are established by the Energy Policy Act of 1992 (EPAct). The energy-efficiency metric for non-residential models is: Thermal Efficiency (TE).

Scope: File includes both residential and non-residential-type models, and contains data on over 2,000 residential-type models from more than 25 manufacturers (available in DBF, comma-delimited, or ASCII format).
Includes steam and hot water boilers for space heating, and boilers that can be used for either space heating or to heat domestic hot water.
Includes boilers ranging in input from 30,000 85,000,000 Btuh.
Includes natural gas, liquefied petroleum gas, electric, and combination-fired boilers. (Oil-fired boilers are not required to be certified to the Commission but data may be submitted voluntarily by manufacturers.)
Scope:
Two lists cover both types of gas boilers:
- 88 hot water models from 10 manufacturers with Annual Fuel Utilization Efficiencies (AFUE) > 83.0 %; Capacities from 43,000 139,000 Btuh.
- 41 steam models from among 10 brands with Thermal Efficiencies >= 81.0 %; Capacities from 81,000 173,000 Btuh.
Two lists cover both types of oil boilers:
- 94 hot water models from among 20 brands with AFUEs >= 86.0 %; Capacities from 62,000 147,000 Btuh.
- 31 steam models from among 11 manufacturers with AFUEs >= 86.0 %; Capacities from 78,000 151,000 Btuh.
Models are grouped by size (capacity), and listed in order of descending AFUE.
