Heating pump running most of the time

[nick69]

Hi all,

I have recently moved in to a rented house for the first time and its great apart from one thing, the heating pump runs most of the time.
I was told it was probably a faulty 3 port valve head so just replaced that and as soon as the power was back on the pump started running again. The heating/hw goes off at 9am but the pump is still running when I get home at 6pm, then other days its not.

The landlord has said as long as there is hot water and heating they will not look in to it for a while as they have other places to fix first. The problem is the pump is in the bedroom so some nights its running all night then others its not.

Could anyone shed some light on what might be causing the pump to running intermittently for long periods of time?

There is a room thermostat, and the boiler is a Baxi WM 40/4. The tank stat looks pretty old tbh and has no noticeable click when you turn the dial on it.

Many thanks
Nick

Could be a sticky stat or faulty PCB. This is down to your landlord to fix not you.

Tell your landlord you have other things to spend your money on, other than paying (rent) for the use of a heating system that doesn't work. In the meantime, shut the whole power off to the boiler 30 mins after it is no longer required to fire.
