Hi,
I wondered if someone might be able to help with a couple of problems we've been experiencing with our combi boiler - a Potterton Gold 24 HE, installed in our loft.
We had a magnaclean filter fitted last year after requiring a replacement heat exchanger due to build up of sludge (the boiler had only been in place for 2 years but we live in a '70s house with original radiators) and everything seemed fine - I checked the filter every few months and cleaned it as advised by our installer, though as there appeared to be a relatively small amount of buildup, they suggested that it could be left for a longer period and I was confident that the system should be fine for a while.
Anyway, over the last couple of weeks, we've started hearing the banging sounds from the boiler again that we had prior to the last heat exchanger being replaced, though as before, it doesn't happen every time the boiler comes on (though it is usually first thing in the morning). In fact, if we turn the heating off when it's making the banging noise and then back on again, there is no noise and the system functions fine. The return of the noise also coincided with the exceptionally cold weather we've had and a pressure drop in the system. Since I've repressurised it, we've had no further noise and I hoped that I might have solved the problem (though it has only been just over a week)!
However, the other day I noticed that the floorboards under the boiler are slightly damp and so I'm now starting to think that we might have a bigger problem. I've left a tray under the boiler in case of drips ever since the leak we had last year (same time as the heat exchanger but apparently it was a seal that had gone from somewhere) and no water is accumulating in that, which makes me wonder if it's something to do with the pipework coming out of the boiler that sits behind the tray. It's difficult for me to tell as the pipes are wrapped in insulation foam and I'm worried about damaging anything further by diving in! Additionally, it doesn't appear to be a lot of water so it's difficult to trace its origin. I'm naively hoping that it might be condensation from the cold weather but I know that's really unlikely and so would appreciate any opinions as to what this is likely to be?
Thanks in advance,
Dan
