Thanks Guys for your replies...
Hope the plumber will fix the issue tomorrow...and will not try to tell me that this is a correct configuration!
I am also worried that the pump is damaging itself or the 2 automated valves (when valves closed and Pump in overrunning)...I have seen a leak right...
Hello All,
First message here. I had a new boiler and unvented hot water cylinder replaced yesterday. Same system as the previous.
I have an S plan system with 2 valves (2 way each) for the HW and CH. I attach a diagram.
The guy fitted also an automatic bypass which goes from the Flow...
