heating problem

[skiprat]

Any help would be appreciated.

We have 7 radiators on our system 4 upstairs and 3 down. The problem is that if we have all the radiators on upstairs (red hot) the downstairs ones go stone cold, it all seems to be linked to one bedroom radiator because if I turn this particular one off, all radiators work properly up and down. but when you turn it on (it does become hot too) all downstairs rads go back off, but all upstairs remain hot.

Any ideas will be appreciated.

What happens if you have it half on?

If the bedroom rad is half on, the kitchen rad goes stone cold the other 2 go luke warm slowly but eventually go cold. Strangely to get the kitchen one back on you have to turn all upstairs rads off first, but as soon as it is hot you can turn all rads upstairs back on except the bedroom one.

It could just be a simple balancing matter.

A drawing of the heating side showing how the radiators are piped together and with the rads labelled would help.

try opening it as little as poss, just enough to get heat in the rad.

try that.

sounds like the rads need balancing, but that may work.
