Having a problem with my Halstead boiler. The hot water will not stop firing up. It causes the radiators to get hot throughout the house. The only time it switches off is if you turn the hot tap on for a minute and turn it off. the boiler will temperarily switch off for about 15 seconds and then fire up again. When the central heating is switched on the boiler will switch it off and start the hot water heating again. The pressure also rises dangerously high making me have to switch the whole system off.
Hope this makes sense.
Any Ideas as to causes would be much appreciated.
