Hoping someone can help.
We have inherited a Halstead boiler. So far so good with it, but I have noticed that the pressure guage reads just below 1 bar when in use, and drops down to 0.5 ish when idle. Shouldn't it be slightly higher than that? I have looked to increase the pressure slightly, but can't actually see any valves to enable me to do this. Can anyone give me some pointers?
Thanks in advance.
