Ideal for homes in northern regions, Lennox® boilers integrate easily with existing radiator or under-floor heating systems for energy-efficient comfort, all winter long. With efficiency ratings of up to 95% AFUE, Lennox boilers can help you save hundreds of dollars each year in utility bills, compared to older and standard- efficiency boilers.
While forced air heat is most common, those who generate heat with boilers -- also known as hydronic heating -- love having that home heating option. Like furnaces (covered in our discussion of gas and oil furnaces ), boilers can be powered by oil, gas or electricity.
With a standard boiler, some of the energy that is used to heat the boiler, whether it is a fossil fuel or natural gas, is lost in the process of conducting. A high-efficiency boiler is designed to trap the escaping heat and direct it back into heating the home.
