Why ENERGY STAR?
ENERGY STAR certified boilers have annual fuel utilization efficiency (AFUE) ratings of 87% or greater for oil boilers and 90% or greater for gas boilers. AFUE is the measure of heating equipment efficiency. They achieve greater efficiency with features, including:
- electronic 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 drafts and improving safety
An ENERGY STAR certified gas boiler can save about $780 over the lifetime of the product, while an ENERGY STAR certified oil boiler can save $420 over its lifetime.
ENERGY STAR products are certified to save energy.
Our partners sponsor rebates on certified products.
