Just on the off chance someone could help:
Over the past week or so I have noticed that if I turn off my heating at the timer box (British Gas EMP2) the radiators still stay warm. It does not actually seem to turn off even if the thermostat is set to 0. If I turn the timer off by the wall socket it seems to switch off, but then obviously the hot water goes off too. This never hapened before until I started using the heating more frequently. I had always just turned the heating off at the switch before.
The house has what I think is an emersion boiler (massive green tank in airing cupboard), and a back boiler behind the fire place (it's an ex-council house) if that has any bearing on the situation.
Am I doing something wrong? Is it because the thermostat is knackered/timer box knackered?
Any help gladly received!
