Hi
New to the forum and I have a question which is probably pretty basic but I can't find anywhere on net with an answer to it!
It is, are central heating pumps designed to stop when they can't pump water due to the circuit being closed due to water and heating stats closing the motorized valves?
The reason I ask, is that our system is fully pumped with two 2-port motorized valves and the pump runs continusouly (with boiler coming on periodically) event when stats turned down and controller off so I suspect that the motorized valve to the how water cylinder is faulty (since central heating does go off as expected). There is a gate valve at the bottom of the cylinder which I think is the output of the heat exchanger (the existing MV is just above that on a pipe around the middle of the cylinder) so I was wondering if a temporary solution to stop the hot water running all night could be to close this gate valve at night. When the heating valve shuts too, would that stop the pump from running or could it break the pump even?
Any advice most gratefully received !!
