Upstairs rads hot, very hot, down stairs rads cool, 6 rads upstairs, 5 down stairs. Removed and flushed all rads, verified that valves are fully functional.
The system is a sealed pressured system operating at 2bar.
Pump fully functional, even bled the pump.
Down stairs rads are hotter at top of rads, bled all rads...no air in system.
Pump in use is a myson with 3 settings 1900rpm thru 2500rpm. doesn't matter what setting pump is set at the rads down stairs remain cool.
Any advice would be appreciated.
