guess you got to go hunting

is there one on the hot water? its not a 3 port valve is it?

Nope not any valves in sight only two pumps one comes on when hot water is switched on and other pump comes on when central switched on but boiler only fires up for hot water only.

In cupboard there is a electrical connector strip with am sure 4 grey power cables coming from wall into connector strip then the two pumps are wired in separately also the cylinder stat f

sounds like the prog is controlling the boiler and pumps, so could be a problem with the heating side of that

but system could do with updating

Also forgot to say opened the centre screw on pump for central heating when it was running but never seen any water coming out is that because motorised could be stick on hot water?
