Hi,
My CH radiators dont warm up...
I have a Boulter Boiler which has two flow and two return pipes.
One flow/return is used to heat the HW cylinder and a bathroom radiator.
The other flow/return is for the CH. The HW and CH pipework is completely separate outside of the boiler.
I have recently removed/cleaned/decorated/refitted all radiators including new TRVs (apart from one rad). All valves on all rads are open, all rads bled.
When I turn on the boiler it runs for about 6 min then switches off. The HW pipework does get hot (cylinder and rad). The CH flow from boiler is hot (for about 1m) but rest of CH pipework (inc rads) is cold.
The CH pump (ikon) has electricity but I cannot hear/feel it working. Pump does get hot but the pipes into/outof pump are NOT hot.
Have tried to bleed the pump but when I undo screw no water comes out.
The bleed screw does not come out.
Have also tried giving the pump a little nudge.
Cannot see where to manually turn pump (using screwdriver).
As far as I can tell the gate valves around the pump are all open.
Any thoughts most welcome,
Andy
