Do i need to bleed the radiators?

amarg

Balancing the radiators is nothing to do with the pressure in the boiler.

With sealed systems if the pressure drops it will require re-pressurising, like this- http://www.ultimatehandyman.org/videos/118/how-to-re-pressurise-a-combi

That video should really be called how to pressurise a sealed system as it does not just apply to combi boilers. But at least is shows how to do it. There are a couple of things that can also be picked up on in the video, but at least someone has gone to the trouble to make a video and it is free, unlike many sites on the net which charge for such info.

For balancing see here- http://www.invensyscontrolseurope.com/NR/rdonlyres/8850B04F-5323-48E3-BD8B-B33ADB04A2E5/7139/D348v2.pdf

Sorry if this isn't where I should post this but I think my problem is similar. My central heating is okish but my problem is that upstairs I have 2 double radiators - one of them works perfectly but the other one doesn't - the back of the radiator works perfectly but the front one is cold - I tried bleeding it but as soon as I turned the key the water came out so I had to close it again so the radiator at the front is still cold. Any suggestions anyone? I would be really grateful because it has been like this for ages and the room is cold all the time. I do not have a combi boiler - oil fired central heating.

Many thanks

Hi
I went to bleed the radiators last night and had the little key thing but where I expected to see the valve to turn is more of a screw - am I looking in the right place (top right of radiator) or are all radiators different?

On my radiator it was top right-a square thread. key fits over top of square thread on mine.All radiators are now er ..radiating nicely.

double radiators have too be bled twice,once on each radiator? The water will come out-thats ok. see post number 8.

use a flat screwdriver, makes ure the head is long enough otherwise you will wreck the head. hope that helps!

For double radiators - front one is inside top left and back one is inside top right - at least that is how it is on all mine.

Might have a white cover on the front of the hole which you need to remove.

While bleading radiators remember to turn off the bolier/ not have the heating on, as this can draw air in to the system.
