ABSTRACT:
An energy efficient heating system is provided for use with a fireplace or like means having a flue which recovers heat which is otherwise exhausted through the flue. The heating system comprises a heat collector in the form of a fluid conduit which is mounted within the flue and a housing positioned outside the fireplace. A holding tank having an open top is contained within the housing while the outlet from the fluid conduit is open to the tank. A drain on the tank forms a fluid outlet which is connected to the inlet of a heat exchanger while the heat exchange outlet is connected via a fluid pump to the inlet of the fluid conductor. Thus, upon activation of the fluid pump, a fluid, preferably water, is continually pumped through the fluid conduit while the exhaust gases passing through the flue heat the fluid. In addition, a fan is provided within the housing which circulates air through the heat exchanger and into the area which is to be heated.
