Central Heating Issue

[skr8]

Hi,

I have absolutely no clue about boilers whatsoever so I'm looking for some advice in case its a simple issue. Basically none of the radiators are heating up but they are all slightly warm to the touch. It doesn't matter what temp I select on the thermostat. The status on the boiler says C and the burner light is flashing. The water heats up fine, although a littler slower than it usually would. I noticed the pressure gauge is on about 8 PSI but have no clue if that's anything to be concerned about. Any help appreciated. Its an Ideal HE35 boiler if that makes a difference.

Thanks.

Might be the diverter valve sticking

Model ? Icos, isar etc.

Sorry, thought I had. It's the isar. It's started working as normal again today, not sure how long that will last though...

Have you checked the batteries in the remote ? (Thats if it is wireless). Or as already said, it could be a sticking diverter as the boilers seeing the demand.
