Gas Fireplace Thermocouple Vs Thermopile

The thermocouple on your gas fireplace is a heat sensitive device that keeps the pilot gas tube open while the pilot is lit.

Gas fireplace thermocouple vs thermopile.

A thermopile generates electricity from the heat of a pilot light. It generates about 750 mv that turns on the main gas valve to the fireplace. It is typically more sensitive than a single thermocouple. A thermopile is a series of thermocouples and are used typically when the difference in heat is hard to measure.

When turned on the pilot in a gas stove generates heat which travels through a thermocouple.

The main difference between thermocouple and thermopile is that the thermocouple is a thermoelectric device and thermopile is a device that converts thermal energy into electrical energy. 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.

A thermocouple is heated by the pilot light but it.
