Firstly thanks to Chris R for pointing me in the direction of my cold water feed blockage. The next problem may be what caused the water to be pushed into the expansion tank in the first place.
My Boiler is a Myson Apollo 30/50 with a High/Low thermostat switch on it. The boiler will now run smoothly with no kettling and all the radiators get nice and hot but the boiler will not shut down until the over temp stat in the thermocouple shuts it down and the pilot goes out. I have replaced both the High stat and the Low stat today with no difference. The pump appears to be working and runs on if I manually shut the boiler down by turning the thermostat switch to off. The boiler cuts in and out ok if i use the room stat or the tank stat. It just does not want to cut out using the high or low boiler stats. The radiators and hot water are getting a lot hotter than they used to so I don't think its the over temp stat operating to early.
HELP
Cheers
Dave
