Hope you can help.
We have had a problem with our UFH which was ultimately traced to an electrical issue. We have had a new electrical control unit installed and all seemed okay (we had heat!) although we haven't been able to control the heat. The rooms that the pipes run through from the boiler to the manifold are pumping heat out uncontrollably.
I have turned all the thermostats off (a couple of days ago) and all the heads on the valves are down. The pipes to the manifold are all hot but there is no heat going to each room (as the valves are shut and the pump is dormant).
I'm struggling to get my head around why the boiler is pumping heat to the manifold if there is no demand? Could this be a fault with the UFH valve at the boiler (which is open despite there being no demand)? I say open as the pipe is hot both before and after the valve.
Hope you can help.
