Abstract
The ancillary heat pump apparatus of the present invention for producing domestic hot water generally includes a domestic hot water heat pump having refrigerant and water circuits which are operatively disposed at the proximal ends thereof into close array at the heat exchanger of the domestic hot water heat pump. The refrigerant circuit of the domestic hot water heat pump hereof has a heat exchanger coil disposed at the distal end thereof, and the water circuit is connected at the distal end thereof to a hot water heater. In the apparatus of the present invention, the distal refrigerant circuit heat exchanger coil is disposed into operative heat exchanging position, directly or indirectly, with a return fluid stream of a heat source. In preferred embodiments of the present invention, the heat source may be selected from the group consisting of (a) a space conditioning air stream heat pump, (b) a heating and air conditioning system, and (c) a hydronic distribution HVAC system. Other forms of a heat source may likewise be utilized.
