Thermocouple for Junkers water heater and boiler.
It's possible your original thermocouple is made of copper and is shorter. Junkers has replaced these with newer, longer, and more robust ones.
Check the list of compatible models below to see if your heater or boiler is listed, or send us a message.
Possible thermocouple failures include the pilot light not staying lit. Sometimes, the thermocouple head can be visibly burned or broken.
Thermocouple, single thermoelement for Junkers W series heaters.
Check below to see if your model is listed. Your original thermocouple may be made of copper, which contained a gas.
Junkers has replaced these with gasless thermocouples that are compatible with all models of their brand. They are long enough to fit all models; if there is too much extra, it can be easily coiled.
The thermocouple, or thermoelement, is an essential component for keeping the water heater lit and the burners running. It is directly connected to a coil that must remain open to allow gas to flow.
