After some problems with a 3 way valve I have now discovered that the central heating only works (by this I mean the radiators get hot) when there is demand for hot water. To be exact the boiler only starts when the hot water is switched on and requires heating.
Any suggestions for solving this...
I am having problems with this valve buzzing which I assume is going to mean replacing the valve head. Any advice on this (mainly the electrics) would be appreciated. Thanks
