I had just taken taken a radiator of the wall to do some decorating. After refitting radiator and filling system I am finding that when I turn the central heating on, the pressure rises from 1.0 Bar to about 3 Bar within seconds it then climbs at about 0.1 bar every second. I then switch it off. The pressure then returns to 1.0 Bar. During this time the radiators are starting to heat up. There is no problem with the DHW side of things.
The boiler is under 2 years old and I have 6 radiators connected to it with 10mm microbore through a manifold system.
I've tried cleaning the filter at the heating return (not very dirty) and made sure the cap on the automatic air vent on top of the pump was undone.
Still the same.
Any help would be greatly appreciated.
