Cold radiators

fatherted1969

Hi folks

Looking for some advice. I live in a former bungalow and upstairs along the back of the house I have 3 radiators, bathroom, hall and bedroom. I'm guessing they are all on the same line. No reason to think not. Bathroom and bedroom are cold with the one in the middle heating fine. There's plenty of water running through them as I've bled them and that's not the problem

Yesterday I turned off all the rads that are heating ok to see if the heating coming from the stove would get them working but other than nearly blowing up the heating system when boiling water started gushing out through the overflow pipe it had no other affect. I checked the small tank in the attic afterwards and it looked like dirty water came from somewhere but the rads remain cold

Any ideas would be appreciated

Have they thermostatic valves fitted ?
Have you checked the lockshield valves are open?
Have they ever heated before?

Cheers for the reply. Yeah they have. The one in the bathroom is one of those towel rads and was working last winter. Never needed it all summer so don't know when they stopped working. Forgot to add it's a dual system I use. Oil hearing plus stove with back boiler in kitchen. Both have no affect on the two rads.

Last year I changed all the downstairs rads to thermostat valves. I'd probably be near the max output for the stove but even using oil burner has no affect either

Pop the TRV head off the rads and make sure the pin in the valve pushes up and down, don't pull the pin, just make sure you can push it down.

I haven't got around to changing the valves upstairs to thermostat. Just normal valves upstairs. Would that make a difference ?

Presumed you ment they have TRVs fitted as thats what i asked.

Have they worked since you replaced the downstairs rad valves for TRVs?
Possibly an airlock.

The ones downstairs all have thermostat valves, I got them fitted last year. Hadn't got around to changing the upstairs ones to thermostat valves yet so they are just the normal valves. I've checked all the bleed screws and there doesn't seem to be air in any of them. They did work alright but not at the moment
