Energy Star Certified: Boilers

Keeping your customer’s home at a comfortable temperature can be expensive. A typical household’s energy bill is around $1,900 annually, and almost half of that goes to heating and cooling! So making smart decisions about a home’s heating, ventilating, and air conditioning system can have a big effect on utility bills — and comfort.

Replacing your old heating and cooling equipment with new, energy-efficient models is a great start. But to make sure that you get the best performance, the new equipment must be properly installed. In fact, improper installation can reduce system efficiency by up to 30 percent – costing you more on your utility bills and possibly shortening the equipment’s life.


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.
