Hello, my name is***** be patient whilst awaiting any responses as I'm not constantly available.When you put your heating on the water heats up and causes pressure to build.. when you turn it off, eventually the water cools and therefore the pressure decreases
if i leave the heating for 5 minutes the pressure keeps rising into the danger zone so i have to knock it off
what pressure does the gauge fall to when it is switched off?
it falls slowly to 1 half bar after about 4 minutes
How high is the pressure going up when you turn the boiler on? There is a pressure relief valve on all modern boilers that should kick in at some point
it is going up to just over 3bar then i knock it ff
the pressure only rises when the central heating is put on.the pressure is ok when you are just running the hot water
