We have a Baxi 85 Boiler which is just over 18 months old. Yesterday I called a local engineer to come round to give it a routine service. He spent about an hour or so checking the boiler and the upstairs radiators and gave us a clean bill of health. He even commented on how clean the system was and he said that in his opinion, the boiler was in excellent perfect working order.
Anyway, last night when I jumped in the shower I noticed I couldn't get any hot water so I went to look at the boiler.
Both the flame indicator light and the 30degree temperature lights were flashing and the pressure gauge was all the way down to zero.
So I increased the pressure to about 1.5 bar using the feed taps underneath the boiler and everything seemed okay again.
This morning however, the pressure was way back down to just above the zero mark so I called the engineer back out to find out what the problem was. He was dumbfounded and said he really couldn't figure out why it was causing me the problem.
He said that the Pressure Relief Valve might be sticking open but that was unlikely because of how clean the system is. So he gave it a "flick" to test it and has told me to keep a close eye on how things go.
He also got out a foot pump to increase the pressure in the compression chamber which he said was a little bit low.
We have a small 2 bedroomed house with 2 upstairs radiators and 4 downstairs radiators and he did mention that the boiler did appear to be running at a slightly high pressure which seemed a little odd because the house is so small.
Anyway, I've been asked to keep a close eye on the gauge and I've been told that if the pressure keeps dropping then I should "flick" open the pressure release valve to release it (in case it is sticking). He reckins the cost of a new prv is about £3 with half an hours labour.
He has also told me that if the pressure constantly increases then I should give him a call back and he will then need to investigate the cause of the underlying problem.
So I was just wondering if any of plumber types on here might have a clue as to what might be causing my boiler problems? Any Baxi experts out there?
