eco 7 boiler/heater.. the light comes on (a) the correct time but its not heat up the water? - the primary setting is still working & heats up the hose fine?
Answers: If the boilers main burner doesn't buoyant up when you run the hot water, afterwards it could be any of many fault. I would suspect the Domestic flow valve is malfunctioning myself. This is the valve that allows the hot hose down to run out of your hot tap.
it is probably because the lantern means its on, but the furnace might be broken even with the power on
