Rads ok downstairs, cold upstairs

wazzag · 20 Feb 2008

Hi,

I have a pumped, boiler/cylinder system which I have recently drained and refilled after fitting a new rad. The downstairs rads are ok (although could be hotter) but the upstairs are all cold.

Any ideas anyone?

not enough water
iinadequately bled
air lock

Try closing the working rads and hope for gurgles.
Vent air by the HW cylinder too.
