Gas Furnaces

Coleman  has a full line of makes and models for every application. There are two generic “types” of furnaces, CONDENSING and NON_CONDENSING

Echelon 9S FurnaceCONDENSING gas furnaces:   These are the +90s gas furnaces or 90 percent efficient – also known as High Efficiency. Coleman has a 95% single stage gas furnace, a 96% efficient two stage variable gas furnace and a 98% efficient modulating variable furnace. The gas heat is off or on in a single stage furnace, the gas is 50% on and then 100% on in a two stage, and the modulating furnace has fifty stages of gas up and then 50 stages of gas down as it turns off. these provided better heating comfort and temperatures. on the air blower  a single stage has just one speed of blower, on then off. A variable speed blower has infinite blower speeds used automatically during the heating process. this blower is direct current saving about $100 per year in electricity. And it is very quiet…. twice  as quiet as a single stage blower. All condensing furnaces use a plastic pipe for a flue. This pipe drains the condensing water in the flue pipe back to a drain or condensate pump. We cant use the metal flue pipe like the old furnaces.

NON CONDENSING gas furnaces:   These are the +80s gas furnaces or 80 percent efficient – also known as Mid Efficiency. Coleman has a 80% single stage gas furnace, an 88% efficient modulating variable gas furnace  The gas heat is off or on in a single stage furnace and the modulating furnace has fifty stages of gas up and then 50 stages of gas down as it turns off. these provided better heating comfort and temperatures. on the air blower  a single stage has just one speed of blower, on then off. A variable speed blower has infinite blower speeds used automatically during the heating process. this blower is direct current saving about $100 per year in electricity. And it is very quiet…. twice  as quiet as a single stage blower. We use the metal flue pipe like the old furnaces for flue venting.
