ABSTRACT:
A method of maximizing available but unused heated air located in the plenum of a furnace which comprises sensing the point at which air within the furnace plenum is sufficiently warm to provide valuable hot air but is still below the activation temperature of the furnace blower and displacing said warmed air into the air flow paths for a room air space, and continuing said displacement after the furnace blower has shut down until the air within the plenum reaches the point at which it no longer has valuable heating capacity. The device is a heat sensitive thermostatically controlled unit which comprises a small horsepower, low energy consumption air displacement motor. Associated therewith is an air deflector for directing displaced air into the air paths for a room air space and also associated therewith is an air temperature sensing switching means for stopping and starting the motor in response to sensed temperatures within the plenum of a furnace.
