HI, thanks by flow & return valves do you mean on the ch system?
If so do you know where they are - the things i thought were islolation valves are drains (which was a shock).
Currently it's pressuraing about 1bar more than the cold temp.
I was thinking that if 1 put 1.5bar back in (0.5bar more than now) it should stay about 2bar but if it goes above 2 then it points to the vessel.
What cols pressure? do you mean cold pressure?
Thanks
Dan
