Lochinvar & A.O. Smith 100093972 Natural Gas Thermopile Assembly

The Lochinvar & A.O. Smith 100093972 Natural Gas Thermopile Assembly is an essential part of gas-fired water heaters and heating systems. The thermopile shown here extracts heat energy from the pilot light and converts it to electrical energy to provide the correct voltage needed to safely regulate the gas valve. As a result, it adds safety to the heating system and increases the robustness of the rod by providing a consistent and reliable power source other than the gas. Due to its durability, it is widely used in HVAC equipment and increases its service life.
