Hi guys wonder if someone could help.
Hot water on a gravity fed system (y plan) is far too hot. Tried swapping cylinder stat but is the same. With hot water on the boiler fires up even when cylinder stat is set at 50c. If I turn the stat down lower the pump and boiler go off.
Customer has hot water on constant all day.
Thinking maybe 3 port valve?
