About Hybrid Heating

A Hybrid heat system reacts to changing temperatures and automatically adjusts to the most efficient energy saving method available to heat or cool a home. It is a fuel-saving alternative to traditional heating and cooling systems in that it combines a furnace with a heat pump, rather than an air conditioner. With hybrid heating, a heat pump works as an air conditioner in hot weather, but can also reverse the process and heat the home when cold weather arrives. Rather than burning fuel to generate heat, the heat pump moves heat without a flame, making it a more efficient method of heating a home. Hybrid Heating is adaptable for gas or electric systems and by using a variable speed fan hot or cool air is distributed consistently and evenly throughout a home.
