central heating

i have several radiators that are cold in the middle, no air in the system bleed.balanced any ideas ? cheers

gas is pretty much dangerous! might be best to get an expert to work on it!

thank you but I never said it was gas !!!!!!

Could be a build up of sludge - if you can shut off the valves at either end of the radiator you should be able to disconnect the valves from the radiator. You'll get a lot of very black (very staining) water coming out so use loads of absorbent stuff to catch it. Ideally take the radiator outside and thoroughly flush through with garden hose.
Hope this helps. Andy

Make sure your central heating pump is working.

not sure where muffinman got the gas bit from, its only water in radiators not gas, lol
