Method for raising the efficiency of a heating system has thermoelectric converters outside a building and in the heating system to provide electrical energy

摘要

One thermoelectric converter (1) is positioned outside the room or building (10) and the other (2) on the heating system flow pipe (8) generating a direct voltage through control unit (3) which is converted to a sinusoidal waveform (4) connected through a switch (6) for use (a) or to the mains (b).
