All radiators are warm when central heating is off.

gopakumarsukumaran · 7 Feb 2012

I have Potterton Suprema 50L boiler. My central heating is off but all my radiators (upstairs and down stairs) are still warm all the time if any have an idea to sort out this problem.

Thanks kindly

could you take a picture of your airing cupboard?

could be you've got a stuck open zone valve and/or a faulty thermostat that is calling for heat constantly.

is the boiler still firing while the heating is off?
