Hi there the highest radiator in my central heating system was cold so i knew it needed bleeding. The system is powered by a Valiant Combi boiler and the pressure was low (0.5), so i topped it up as recommendedon several posts, to about 1.4, whilst bleeding the radiator. Now when the boiler runs the pressure increases to above 2.2 (not too sure how high it would go as i'm switching it off when it gets to 2.2). After reading several other posts i'm now not so sure that i've used the correct "taps" for topping up the pressure.
I intend to let the system cool down and then release the pressure back to where it was and run the system again. Any advice on what could have gone wrong? is the increase in pressure normal? am i worrying unduly?
