Abstract
What is disclosed is a water heating system characterized by a remote hot water storage tank having water interconnections with a heat pump unit and a remote, timed water circulating pump and water circuit incorporating temperature sensor and thermostat. The heat pump unit is adapted to be employed at a location near a kitchen or laundry room and includes conventional constituents such as compressor, condenser, expansion device, and evaporator connected in a closed refrigerant circuit; blower for circulating air from conditioned space across the evaporator; and pump for circulating water past the hot refrigerant gas in the condenser. The condenser comprises a double-walled heat exchanger for preventing contamination between the respective fluids. The heat pump unit comprises a cabinet housing the same and having a warm air inlet adjacent its bottom and cool air outlet adjacent its top. The control means enables periodically circulating water to sense its temperature and turning on the heat pump to add heat as needed.
