Radiators getting warm during shower or when taps are in use

[alex889]

Hi guys, I'm having a problem when showering/using hot water on taps where the radiators start to get warm after a few minutes. I believe there is a valve on my boiler that controls the flow of water into the system and it seems to be stuck in my opinion. Normally using shower or taps would not make that radiators warm, but recently it started to happen.

I have an Ideal boiler, and I'm wondering what can I do myself to fix it or if this is a bit more complicated job that I won;t be able to sort myself?

Thanks!

Depends on the actual boiler model/name. Have a look at which model/name your boiler is as they vary.

Im assuming you have a combi boiler so therefore your problem is likely to be due to the diverter valve letting by, is the water less hot also as that is another symptom when the valve is letting by.

it sounds like a divert valve from what I've been reading but it seems a bit of a challenge changing it so I'll get a plumber to check it, thanks!
