Abstract
A heat pump system is disclosed that utilizes a variable speed hydronics pump to selectively divert heat energy from a forced air heating system to a hydronics radiant heating system. By actively controlling the speed of the withdrawal of heat, the temperature of the forced air output may be maintained while maximizing the amount of heat delivered by the efficient hydronics system. The heat pump system also actively controls the blower of the forced air system. To reduce the frequency of the compressors cycling on and off, a tank may be used to store and dispense heat if the hydronics system is not of sufficient size.
