<p>A gas-operated generator heater having a thermoelectric energy converter in a heater housing, in which combustion air can be introduced from the surroundings and a gas-air mixture can be supplied to a burner via a blower having a downstream mixing device, with the blower taking in combustion air out of the heater housing and the gas being capable of being supplied to the mixing device, while the heat produced by the burner can be conducted to the thermoelectric energy converter for conversion into electrical energy and the part of the thermoelectric energy converter to be cooled is also cooled. Expensive water cooling of the thermoelectric energy converter, which is susceptible to breakdown, can thereby be dispensed with in that the part of the thermoelectric energy converter to be cooled is surrounded by a pot-shaped cooling tank to which the combustion air can be supplied in the bottom area from the surroundings and the combustion air heated by this part flows into the heater housing via the open top of the cooling tank.</p> |
