Bosch/Buderus DHW temperature sensor failure
I have a Bosch Greenstar boiler with a TT Smart indirect DHW tank. The Bosch/ Buderus boilers use their own cylinder temperature sensor so you have to take out the Smart tank aquastat and insert the sensor in its place. Supply water is treated for hardness and iron. My boiler is only 3 years old and I have had two of those temperature sensors go bad. I called Bosh customer support and they say they have not had any trouble with those sensors. Anybody else run across this issue or have any ideas for a cause?
