Hello,
Winter approaches and I need to sort out this long-standing problem...downstairs rads are piping hot, upstairs cold. Baxi back boiler works fine, pump is good. Ive tried turning off the rads upstairs and on again one at a time. Ive tried bleeding them all, and get cold water which appears to be under some pressure; it spurts rather than dribbles if I completely remove the valve. I've checked the tank in the loft too. The system is about 30 years old, but some new rads were added before I bought the house. It all worked ok for a couple of years.
Any advice would be greatly appreciated.
Thank you very much
Norman
