Thanks to both 45yearsagasman and Bamba71....And sorry for the very late reply, i thought i'd have a look first at your suggestions and then come back to you...and as the problem disappreared now with the cold i kind of forgot all about it...thanks again
Hi
Even if both heating and hot water controls are off the boiler fires up several times an hour, goes for a while and then off again...
The only way to stop it is to turn the central thermostat -the one on the boiler- to 0. But that means that you cannot program anything as you have to...
