Hooked upto a system the other day and it wouldn't circulate???
Sealed system,Yplan, system chb. GLoworm Ultimate 22mm pipe to pump/valve before it goes undergrground into 15mm.
The problem is poor circulation initially. The boiler cycles off before there is any heat to the rads. Heat gets about 8mtrs fro chb when this happens, which is before the pump and motorised valve
.
Had new pump/valves/valve/motor/sensors
After 1 hour all the radiators are roasting, but the boiler shouldn't cut off before there is heat at the rads. I think the return is choked but can't get nder the floor.
Any way of finding out? Was thinking of running a return pipe from furthest rad above the ground into the 22mm return near the chb, this should confirm that the chb HX and flow pipes are ok yeah?
Cheers for any advice
