I have an Ideal mini combi boiler, having not used the heating all summer, when I switched it on the other day I noticed the pressure was going way too high
Usually it's at just over one when cold, adds about half a bar when heating /hot water is on
It is now just climbing until over 3 bar, at which point I switched heating off.
I turned the radiator water heat dial down (the boiler has one dial for tap water heat and one for rads) which still gives me nice hot rads to be honest, and the pressure only climbs to just over two and stops climbing
But obviously something is amiss... any ideas ?
