Got a bit of a strange one. I have the Hive control system which is connected to quite an old Ideal Classic boiler.
When I turn on the central heating via the thermostat the control light indicates the heating should be on but the boiler does not fire up. However if I turn the hot water on the boiler lights for the hot water straight away.
The only way I can get the central heating back on is to turn the boiler off and on fully. It will then work for a while before repeating the situation above.
Any idea why this would happen as if the boiler was faulty surely it would not light?
Many thanks
