OK, this one's difficult... why not see 'baffled... hot water not reaching radiators' Thank you for taking the time to look. :wink:

Thank you for the gen on air separators... I've got one that looks like a tuba... ... the air separator. :D :) :) :)

Case solved! A dose of DS helped a lot. One of the radiators is very slow to bleed, but perseverance and juggling of valves paid off in the end. Thank you for all your helpful suggestions. The greyhound is an experience... just nip along to your local dog track. :D :lol:

Where can I get an 'air separator'? It sounds as if it might be the solution to my problem, or at least a help... :o

Thanks for your help. The cold feed tank was fine. The pump is fine. I tried shuting down all rads and bleeding back either way through one thaht I thought was near(est?) the pump/cylinder/valves to try to shift what I think is an airlock. Not fixed. I shut off all upstairs rads and...

Another update... There seems to be a fairly regular (every few seconds) gurgling noise, rather like a greyhound farting, that I can hear if I put my ear on the lagging on the pipe to the HW cylinder. I presume that it is actually some air returning fom somewhere on the CH circuit as the HW...

Have tried turning HW off and CH on. Removed motors and turned valves into position manually. Boiler working, pump working, circuit selected. Some air is gradually reaching the bleed above the pump (1/2" per day?). The boiler is noisy sometimes, but not each time that it fires up. None of...

HW fine. Boiler fine. CH not! Two separate valves; both motorised and working. There is no balancer valve... Stats working and controller working. Forced system to pump hot water around CH; removed motors from valves, manually selected CH with no H, forced both thermostats to power pump...

I've just replaced the safety valve on my Myson Orion and I think that I now have an air lock. I've bled all of the radiators: most fine, one above the boiler had lots of air. The hot water works fine, but the radiator circuit does not seem to circulate? I've put a thermometer on the spur and...
