I cleared the airblock by connecting the w/m h&c together and forcing cold through the system. I am told there may be an airblock on the primary coil and should change the pump speed to shunt out the block Does this sound correct?

is this easy to replace?

draw off at top of cylinder is hot up to tee

Potterton suprema 40 boiler hortsmann C27 controller immersion heater works when switched locally if cylinder stat temperature increased boiler fires

turn heating on and boiler fires and rads heat up. turn heating off and boost hot water, boiler doesnt fire. Any ideas?

correct cold water under decent pressure from all taps and showers (apart from power shower). Heating pipes to cylinder are hot.

22mm Gate Valve from loft tank serving the base of the cylinder and 22mm pipe coming off top of cylinder to a tee. Only 15mm branch off tee has a gate valve. Which do you think would be the problem valve?

keep thinking it may be the 22mm cylinder feed valve? but would i have any water at all coming through the hot water taps?

no hot water from any taps

gas fired boiler, turned off before starting work. When i put the boiler on to boost hot water it doesnt fire up but working ok for heating rads.

No, seperate hot and cold water taps

Replaced basin taps in bathroom. Drained hot water tank first. Everything back together and now just getting cold water from hot tap. Checked tank is ok and checked for airlock, still no hot water Not sure what to do next, may be one of two valves in airing cupboard?
