I have a ferroli boiler and the pressure has slowly climbed from one upto four and when it is on now stands at 6 which is max so I have turned it off. I have called out the plumber but have to wait and its freezing. Is there anything simple that needs to be done?? Thanks

If its really at 6 bar you may have a serious problem that requires the attention of a repair engineer.
Oilski could be spot on in what he says but if someone has been stupid enough to cap off your pressure release pipe what other dangers are lurking?
A dangerous Steam incident could be on the cards and you did right to turn it off.Steam incidents with combis are one in a million but dont be THE ONE.
If you are tempted as he suggests to let some pressure out then watch that guage like a hawk if you want to risk running the boiler.
Lets see if we can put the risk into perspective.
Water under only 3 bar pressure can reach 143.5ºC if one or more certain other faults occur in your boiler.
If a part of your system burst under this heat and pressure just 1 of the many litres of water in your system would turn into 1600 litres of steam in a flash turning you into a dizzyb555 steamy roast!
