Radiator problems

johnnyfaddo

Hi all!
Hoping you can help. So I moved into my new home in the summer but a couple of radiators were not working. I have got a couple working now, but I am down to 2. So the one in the living room is not working and the pipes arnt getting warm, the pin isn't stuck and the valve is open all the way. The one in the hall which is next go the livingroom is also not working, it has a lockshield valve on both ends (previous owner said that's normal), so I opened up one end and that was fine, but when I tried to open the other end, water started to come out, so I tightened it again, but the radiator still isn't getting warm, the pipe going to the valve that had water coming out is warm, but still not getting to the radiator.
Hope to hear back soon.

Have you tried bleeding the non working radiators?

If so what was the result

I know this is the Energy section of the forum but I think you might get more replies if you post this on the 'In My Home (Includes DIY) MoneySaving' section.


You could ask the moderators to move your thread.

Most likely there is an airlock somewhere in the heating system which is stopping the water from being pumped through the system.

You'll need a radiator key and possibly a pipe to connect the water supply to the heating system which might be somewhere near the heating pump or even on the boiler.

Very simply, you turn off the heating and wait until it turns cold, connect the water supply to the heating system and turn it on and then starting with the radiator closest to where the heating system starts unscrew the bung at the top of the radiator with the radiator key and have a container handy to catch the water that comes through. You might get bubbling and then water coming through and then close the bung and then work progressively through every radiator in the same way.

That's the theory anyway. In my previous property the water level within the system continually dropped and an air lock was then apparent in the pipes connecting each radiator. To clear the air lock I had to bleed each radiator for quite a long time until the air lock in the pipes was cleared.

Hi all,

Thank you for getting back to me. I did try a couple of things people posted, but we thought it would be best to get a heating engineer out.
He found that the pressure in the system was not correct. This was caused because the water was not replaced when I removed a radiator for decorating and there was air in one of the main pipes. Everything is working now, so we got a good result in the end.

Thank you everyone for your help.

Bleeding L looks like this one is fixed!
