that's it basically. Could it be that there's not enough water circulating in the system? I've bled all the upstairs rads and although there's no more air coming out of them the rads still don't heat up fully (only heat up half way, ish) and water doesn't come out - as if there's not enough water in the rad.
Any help, suggestions much appreciated.
Cheers.
