Why does my heating come on when the timer is off?
If the heating is coming on when it is set to OFF, then the system requires further investigation. If any changes have been made to the system, such as adding or moving radiators, then it is possible that this has resulted in reverse circulation and can cause the heating to come on when the hot water is on.
Why does my boiler pump keep running?
Your boiler has “pump overrun” so the pump is connected directly to the boiler. The pump should run for a few minutes after the call for heat has ended. If the pump runs continuously when the boiler is off the overrun control is faulty. You will need a Gas Safe qualified engineer to repair the boiler.
Why does my boiler make noise when off?
The boiler is ‘whooshing’ or vibrating Whilst there is no immediate danger, allowing the problem to persist can cause further damage so immediate action should be taken. The most frequent cause of a loud whooshing sound is a blockage to the air intake.
Why does my boiler keep turning itself on and off?
If the boiler keeps shutting off, it could be due to closed valves, air caught in the system or a broken pump. If there is enough air in the system to cause your boiler to switch itself off, it should be obvious when you start bleeding your radiators, as plenty of air will gush out of them.
Why does my boiler run even when the timer is off?
The boiler recently started to fire occasionally when the timer was off and the pump runs even though the timer is off. Only resolution is to switch off at power socket. Called a plumber who removed the electric valve to the central heating which I am sure is not the problem as it only controls whether the water goes round the heating circuit.
What should I do if my boiler pump is not working?
Only resolution is to switch off at power socket. Called a plumber who removed the electric valve to the central heating which I am sure is not the problem as it only controls whether the water goes round the heating circuit. I replaced it but think the problem may lie in the frost stat. Any ideas on what the likely problem might be ?
Can a boiler run continuously without CH or hw?
In fact it runs continuously, day and night, even without CH or HW demand, and even with the boiler thermostat control knob turned fully OFF (then the boiler doesn’t run – just the pump).
Why is the Suprima central heating pump running?
Hi, On the suprima the pump is normally weired into the boiler because the boiler has a built in pump overun function. If what captain leaky said is right you will have power on the switch live coming into the boiler but the boiler will also be firing. Get a electric test meter and check see if you have any power on the pump live from the boiler.

Is the boiler still running after a power cut?
Checked the programmer and both heating and hot water were off, the boiler was still running. Radiators cold downstairs and room stat 20C set 21.5C. Had to turn the power to the boiler off to stop it running. We had a short power cut in our street on Fri night 20.00 hrs. and it came back within 5 mins.
In fact it runs continuously, day and night, even without CH or HW demand, and even with the boiler thermostat control knob turned fully OFF (then the boiler doesn’t run – just the pump).
