Thermopile vs. Thermocouple Fireplace | Hunker

A thermopile consists of nothing more than a series of interconnected thermocouples. Each additional thermocouple placed in a thermopile increases the device's ability to produce electricity. For instance, if a thermocouple generates two volts of electricity, and a thermopile contains four thermocouples, it generates two volts of electricity per thermocouple for a total of eight volts. In ...
