All radiators in the house not heating up at the bottom

[anilmakwana1]

hi, i have read many similar problems on the forums, and still have a puzzling query.

Firstly i removed and cleaned all the radiators in the house, with a hose pipe. i added a sludge remover chemical in the system, and ran this for one week. i then flushed the system and balanced all the radiators.
Also from the vent pipe from my attic, hot water flows out when i put the pump speed to number 3, i reduce the speed of the pump to number 2 and the problem is still the same.

if anyone could be of any help, i would be very grateful.
Thanks

Anil

sounds like you have a restriction/blockage around the vent/cold feed to the system.

Thanks for your reply.
if theres a blockage in the infeed, the system would take a long time to refill. but this is not the case with me. is this correct in sayin this?

It seems that you have a serious sludge/blockage problem.

Any pumping over will sludge up a system in hours!

It will probably need serious attention and possibly power flushing.
