Gas fireplace thermocouple vs thermopile. If you have a water heater that has an electronic gas control you have a thermopile. A thermocouple produces a temperature dependent voltage as a result of the thermoelectric effect and this voltage can be interpreted to measure temperature. The thermocouple lasts for 10 years or more and when it fails the pilot wont stay lit and the fireplace wont work.
Understanding the differences between a thermopile and a thermocouple fireplace requires an understanding of the differences between these two devices. This video is part of the heating and cooling series of training videos made to. I test both of them show the difference.
This product was the perfect replacement for the honeywell thermopile in a circa 1975 gas fireplace unit. Thermopile vs thermocouple. For water heaters with a standard gas control before 2010 you will have a.
A thermocouple consists of two dissimilar metals that create a small electrical voltage when subjected to heat. Luckily despite the scientific complexity of thermopiles and thermocouples you can understand their basic purpose through a brief description. This one covers the thermopile and how it differs from the thermocouple.
A thermopile is a series of thermocouples electricly connected in series to get an increased amount of voltage.
