If you are upgrading the residential boiler in your home, U.S. Boiler Company’s high efficiency home heating systems can provide substantial savings and deliver better comfort.
Many older non-condensing boilers have efficiencies ranging from 70% AFUE to 80% AFUE, and boilers older than 25 years could be at 65% or even lower. New condensing boilers have efficiencies of 90% AFUE and better. Replacing an old non-condensing boiler with a condensing boiler provides as much as 30% more efficiency.
A reliable indicator of efficiency is the ENERGY STAR® label. For a boiler to qualify for ENERGY STAR® certification, the product must meet or exceed the EPA’s minimum efficiency ratings. Look for the ENERGY STAR® label to be sure that the boiler you choose uses less energy than other products in its category.
When you purchase an oil or gas boiler manufactured by U.S. Boiler, you know you’re getting the best in comfort, durability and safety. With three models meeting the ENERGY STAR® efficiency standards, we have the most efficient boiler for your home.
