Hi, I have a Baxi system 100he plus which keeps cutting out on overheat. Could any one explain what the flow stat and thermistor does. I am guessing that the stat is a safety cut out ? and the thermistor controls the boiler power relative to the water temp ?
I have accepted the fact that I need a proper boiler guy in but ask the above question purely out of interest.
Cheers.
