Hello,
We have a heat only boiler that provides central heating and also heats the water in the unvented cylinder.
Tge pressure gauge in the airing cupboard has a red line marker at 1.5 bar. Is this the maximum recommended pressure when the system is hot or cold? I have no idea what temperate our system is supposed to be filled too, but it currently operates fine at 0.8 bar cold, 1.3 bar hot.
Thanks
