December 8, 2025Dec 8 The heat pump install proceeds at pace, well two steps forward and one back mostly. Todays one back is this filling loop I got from the plumbers merchant. Allegedly it is automatic, you dial up the pressure you want, open the valves and once it has done its business you close the valves. See if you can see anything wrong with the instructions and the parts as supplied.
December 8, 2025Dec 8 Apart from the drawing being wrong - nothing much wrong. I would do - cold water main to PRV, then the check valve, (long bit), flexible, then the short bit. Not sure I would be filling the heating to 3 bar though. Mine currently sits at 0.5 bar.

The drawing is crap, makes you wonder how good this stuff is. Your right I will be running mine at 1.5 bar - enough to meet the spec of the heat meter but no so much as to blow the socks off.
