Discuss New Worcester 34cdi classic. Hot water ok, Flow hot, return cold, all rads cold in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Have new boiler installed. Central heating and hot water all working before replacement. Flush etc all carried out before replacement. Hot water heats perfectly but no radiators heat and no heat in flow to any radiator. Tried crossing flow and return but no joy. Doesn't seem to be a block in the pipes as checked section where heat is lost. Suspect boiler issue - any thoughts?
Doesnt matter who fitted it, its Worcester that'll come out to check it under the warranty.
Edited. No gas appliance repair advice given on the open forum.

It’s an upstairs bathroom, fed from a tank in the attic. The tank is about 8 Meters away and feeds a bath, sink and toilet. The tank...
