I have a gas powerd central heating and hot water system. It is not a combi boiler, but a seperate heating system and hot water tank. It is all controled from one point, where I can set a programme for the ho water and a programme for the heating didgitally. This contole point was only replaced last year, but the boiler itself is arround 9 years old. Util the beginning of the summer it all worked perfectly. We turned it off through the summer and now when trying to use it again, find it's not right! Neither will turn on when they are set to, the control panel says they are on, i.e the light is on, but the boiler does not fire up. When trying to 'boost' either system this does not work properly either. The only way I can get the boiler to fire up is by boosting one, say the heating, and going through the cycles with the other. I.e I want the heating on for an hour so, I set the heating system to 'boost' then with the hot water button move the hot water from timed to boost, to advance, to constant, to off, when the boiler will then fire up! This is the same for both hot water and central heating.
Any ideas as to what may be wrong? If you need any more info, I will do my best!
