We have an Intergas xclusive 24 which is now 3 years old. The pressure gauge packed up and so we contacted Intergas and they sent one of their engineers, to do a warranty assessment. My wife, who was home at the time, informed me that the engineer blamed the fault on system sludge. A debatable call perhaps, because the entire plumbing system in the house is only 3 years old, was flushed on install and has a magna clean. However, that’s an aside. The issue and reason for this post is that prior to this engineer’s visit, the system was working and was and remains with sufficient pressure. I hear you ask how do you know this, if the boiler pressure gauge isn’t working? Well that’s because we also had a manual pressure gauge (photo from today) installed by the chap who installed our system, after we alerted him to the pressure gauge fault. The engineer informed my wife that there was insufficient pressure in the system, despite not observing that the manual pressure gauge evidences that it does. The engineer annoyingly appears to have mucked around with the boiler settings, possibly under the incorrect assumption that there was insufficient pressure in the system, with the net result that we now have no hot water or heating. So, my question. Can anyone assist me to figure out what I need to do to activate the boiler again, because it’s turned on? When I spoke with Intergas this morning, the chap I spoke with assured me that someone would call me back immediately, however no such call was received. Disappointing customer service in the cost of living crisis as we’re now immersion heater reliant.
