I have just fitted a towel rail in the bathroom upstairs, drained the system to do that, and now filled system back up after doing so.
as subject the downstairs radiators are all cold and the upstairs are all hot.
I have bled all radiators downstairs till water comes out, and same upstairs till water comes out.
What do i do from here?
pump is operating fine on all 3 of its speeds, but does sound like air in system as it makes a fizzing sound every few seconds, and water isnt constant when i unscrew the screw on front of pump
