1 Radiator Feed Not Hot Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

my bathroom radiator is stone cold & the feed pipe is also cold - Not hot coming through

All others good

I added some water last night as pressure was slightly low


Yesterday feed pipe was hot but radiator wasnt - I bled it & didnt fix it
I turned all others off & it worked problem out

I have a similar problem. All my radiators work brilliantly, except for one. I have bled it and that's not the answer. It is full of water, only the water is cold. The feed is hot, and the valve is open, but for some reason hot water doesn't seem to be going into the cold radiator. It was switched off for many years, and since I turned it back on has never got hot. Grateful for any suggestions.

Hi,

Do you have a TRV on that rad?

Is the lock shield valve open?

Cheers

the lockshield valve was indeed the problem - turned out it was turned off. So recommend looking at that for the other person who was having a similar problem - I just needed to unscrew the plastic cap and give the valve a couple of turns open with a wrench / pliers, and problem sorted! Many thanks to the person who suggested this.

hi, sounds like the radiator valve is blocked not allowing a flow through that rad sometimes jus tunrning the valve off then on again works do both sides just incase.
