Hot and Cold rads, upstairs and down.

[Sallyjill]

Help, have 2 rads not working properly. One downstairs, very luke warm, one upstairs just warm, some parts are warmer than others. Have bleed rads and water appears. Boiler pressure is 1-1.5 bar. i do not know how to add any boiler or rad cleaner.. how do you do this? Would this be the first thing to start with.

Boiler pressure is Ok. This is what it should be set to. How old is your system?

My valiant system is about 10 years old. Put in new..

I'm not a plumber but if you read some of the posts on this site you pick up the trends after a while.

If you've got TRVs fitted it would be worth checking that they're not stuck but after that it sounds as though you might have a build up of sludge in the system. This prevents the water circulating round the radiators.

I don't want to give you any duff advice. You can drain the system down and see what comes out, get a plumber to power flush it (varying opinions on this option on this site) or take the offending radiator off and flush it out. That's not quite as bad as it seems as it is possible to isolate it without having to drain the system.

Could it be the pump not pumping the water around ????

I think it could be sludge in the radiator or the system as you say.. however I have never taken a rad off before, and don't even know where to start. I don't mind giving this a go myself as I would like to be more self sufficient... Does anyone know of a good DIY manual I could buy that could tell me, how to, take a rad off and de sludge it, or how to flush the system... and what tools would I need.

thanks for all your help... I do really need to start at the beginning...

Just had a feel of some of the radiators around the house... most of them are not very hot... how do I know if the pump is working or not... they are warm, but not hot.. Thanks
