radiators getting to hot and tripping out. do i need a overheat thermostat replacement. and can i fit it myself. seems easy in the instructions. many thanks

sounds like your themistor has gone out of calibration on the c/h side of you boiler, pressumably you have the electrical testing equipment to check resistances etc on it, probably the overheat stat is doing its job by shutting the boiler down because it is too hot, make sure your pump is running properley and that the water ressure is correct and if you have thermostatic valves fitted make sure one radiator is open as a bypass
