Drained 2 rads to remove whilst painting walls. Rads were in kitchen and living room.
System is a combi, sealed CH system. Drained 2 rads and pressure gauge went to 0 (from 1.5 bar) Was this normal to drop this much for just 2 rads??
Anyhow, on re-fill, the gauge hardly moved, so i left it for a bit not wanting to overfill, then about 20 mins later, the boiler suddenly read 1.2 bar!!
So i tried filling again to get it to 1.5 bar, and no movement seen on the needle.
Another 30 mins or more later, it read just under 2 bar!!
Why is this?? Is the needle or gauge on the combi faulty? Anyway i drained some water from a rad and the gauge is now at just over 1.5 bar again. Hot water works fine
My concern was why the needle was acting this way? Anyone had experience of this before? I believe Worcester are good boilers....
