ABSTRACT:
An automatically controlled residential heating system based on the heat from a fireplace comprising the normal fireplace, hearth, combustion zone, flue, and damper; the flue being divided into two parallel flue passages one of which is unobstructed and the other of which contains a heat exchanger adapted to absorb the heat from the flue gases into air passing through the heat exchanger and then into space heating elements in the residence; the system including automatic devices for sensing the temperature in the residential spaces to be heated, an automatic control to act upon the temperature sensing means and to move a diverter which serves to pass the flue gases into either or both of the parallel flue passages in any desired proportion and an automatic control for an air blower to circulate the hot air leaving the heat exchanger.
