An improvement is provided in a heat extraction device provided in association with a heat exchanger system including a condenser, an evaporator, means for circulating a compressed liquid heat exchange fluid between the condenser and the evaporator and a heat exchanger disposed in the system to heat external water. The improvement resides in the use of conical heat exchanger coils in order to maximize heat exchange, and the provision of control means for sensing pressure, temperature and state of the heat exchange fluid and which regulates the entire operation safely and economically.
