It was 0.4, so we opened up the valve to put more water in, but it went up too high (to 2.5). Trying to beled radiators and close the value just sent it even higher to 3.0. I dont want to put the heating on for fear it'll explode, so any ideas on how I can get it back down to a normal level ? Thanks.
Steve, the pressure relief valve built into the boiler automatically releases the pressure when it goes to 3bar, so you don't have to worry about the boiler blowing up. It will go down to a normal level by itself, also check that the filling valve is shut off.
