Gas Fireplace Thermocouple Vs Thermopile

A thermopile generates electricity from the heat of a pilot light.

Gas fireplace thermocouple vs thermopile.

It generates about 750 mv that turns on the main gas valve to the fireplace. Gas fireplaces and fireplace inserts use thermocouples and thermopiles primarily to generate electricity. A thermocouple is a device consisting of two different metals joined together usually by welding or brazing the voltage between the metals is dependent on the temperature. When turned on the pilot in a gas stove generates heat which travels through a thermocouple.

A thermopile is a series of thermocouples and are used typically when the difference in heat is hard to measure. A thermocouple is heated by the pilot light but it.
