Hi all.

I noticed this winter my living room rad only get hot in the top half.
Radiator is 1600mm(DP SC) double panel single convector.
System was flushed just last year.
Both flow and return values are fully open and don't stick.
Boiler is serviced each year.
Baxi combi boiler about 8 ton9 years old.
Pressure is 1.5bar.
All rads(7) have been vented in the house.

I've tried turning all other radiators off which did heat the rad up, but once others are back on, same again.

My bolier is in the loft with the living room rad and kitchen rad(1800mm DP DC) being the furthest from the boiler. Kitchen rad get hot with no issue.

Any advise to trybfix this issue.

Many thanks.
Mickey.

Hello, We had an extension built seven years ago. Initially the builders' plumber connected the heating to the house system but this didn't work. The builder got him out again and he created a separate heating circuit from the boiler (ie one circuit for the house, the other for the extension)...
