The air does not leak from the tank but it slowly dissolves into the water going through the tank reducing the expansion volume until there is too little to take up the pressure increase caused by heating the cold which comes into the tank. The pressure is then relieved by the relief valve...

Well for anyone wants to know, we eventually sorted the problem after the BG guy had been here for a couple of hours. We put the old ignition board (only replaced 'cos it had come free - I wonder why?) back in. Bingo, it runs. Must have had a problem of some kind. Cheerio.

I have searched the forum for information but do not find anything helpful. I have a 10 year old Barcelona system boiler installed on a system with underfloor heating, radiators and DHW cylinder. There is no heat store, there is a primary circuit from which fluid is drawn for radiators UFH...

I checked out the condensation dripping from the boiler. I found that the bottom cover of the combustion box was loose once again. The condensate trap was full so I emptied that and checked there is no blockage out of the combustion box. That was clear. I refit the combustion box...

Apparently a comment on your (?) choice of boiler. Have you determined whether or not there is a leakage path out of your comustion box. Note that the lighting up of the flame will inevitably produce a pressure pulse insde, most of which should escape through the flue. With my Baxi, there...

Thanks Gert, I think it is not the fan. I have listened to it by pressing a screwdriver on and sticking my ear to the handle (without using glue :P ) Was quiet. Also took the fan apart and checked the fit. No rubbing of the impellor or play in bearings. However, the noise now seems to...

If you have a boiler with a combustion chamber made up of parts bolted together, look for loose bolting allowing gas to escape from the chamber on start-up. I had this on my Baxi Barcelona. The top and bottom covers of the combustion box were loose. When the boiler lit up it shook the whole...

Thank you for the response Joshua. I only just got round to checking for it :shock: Thimble? I am not familiar with this term wrt this boiler. Please enlarge on what you are referring to. Sounds like something in the condensed water discharge system. I have not investigated the water...

Baxi Barcelona system boiler, 5 years old. Problem: it produces a loud whistle (even howl) during parts of the firing, usually as it is modulating down. Lasts for maybe 5-10 seconds as the fan slows. I have recently replaced the combustion box door seal and tightened the screws securing...
