Heating switched off but upstairs rads still warm

diydoo · 8 May 2009

Hi

I have a Britony Combi boiler, I have just realised that the upstairs rads have got warm even though the heating isn't switched on. I noticed this after running a bath. Each rad has a thermostaic valve on them so i have turned them all off.

Please could someone tell me what the problem is!!!

Cheers

Could be as simple as the boiler doing it's occasional pump through to prevent pipework clogging up when heating is switched off.

If that's the case do I need to do anything?

is the heating pipe getting hot when you run the water

Are you referring to that "CG question" thread I posted a week ago?

Op, it may therefore be related to this thread - that's why I'm dredging it up. But probably not since it relates to a conventional system and not a sealed one you have with your combi!

To look like an idiot, or not, that is the question. Or is it

Op - since the heating pipe didn't get hot when you turned the tap, I'll stick by my original guess, er, diagnosis. In which case you need to do nothing.
