Hi - I wonder if anyone can help. Not long moved into a house, new-ish Santon Premier Plus Unvented cylinder fed by a Worcester Bosch boiler.
All has worked fine until recent spring weather means the (thermostat controlled) central heating hasn't been coming on. It turns out that at these times the pump for the hot water is running (it's on a Drayton control) but the boiler doesn't fire.
Turn one of the room thermostats up, boiler fires and hot water starts flowing into the tank again . . .
I'm going to get a qualified engineer in but just wondered if anyone had an idea what it might be?
