Hi
I can currently only get hot water with the CH on.
I have a Potterton Kingfisher on gravity fed hot water system so no motorised valves. When i put the programmer on HW only, the light on the programmer comes on but the boiler does not fire up. Everything is ok when the CH and HW is on. I dont have a tank stat either i dont think. I have searched for answers on the forum but mostly they point to the valves or the tank stat.
Any help would be appreciated.
