Hi guys. I have a baxi 105he which was losing pressure regularly. There were no evident leaks but I then noticed the PRV discharge pipework was hot. The Prv was continually open.
As the system had drained on its own I changed the prv.
I recharged the system but still seem to be losing a little pressure. When I repressurise the system to 1 bar the central heating pressure becomes high (3 bar) but when i open hot water tap the system then becomes lower?
Any suggestions?[/quote]
