Forced Air Furnaces (gas, electric, propane, oil) with an ECM (Electronically Commutated Motor) have lower annual operating costs (25–75% less) depending on your use of the furnace fan. Furnaces with an ECM operate very efficiently with as low as 80 watts of electricity.
ECM (Electronically Commutated Motor) is a brushless DC motor with conveniently built-in speed and torque controls. This allows the motor to adjust its speed to ensure optimal airflow at all times. ECMs are quieter and less expensive to operate than conventional furnace fans.
ECMs use less electricity to deliver warm air from the furnace and cool air from the Central Air Conditioner (CAC) for your home.
