Hi all...
I'm not completely clueless about CH systems, and I have read up before asking, but my airing cupboard has got me stuck, and was wondering if someone could explain to me...
It's a gravity-fed open vented system (there's no valves, and the programmer is in 'G' position). The pump's flow direction in the diagram is going right.
Does this look like a normal system? I don't understand what a drayton TRV is doing in there? Why does the pump outlet tee and then go into the cylinder?
Cheers
Rab
