I wonder if anyone can help me with what may be condensation problem in the boiler cupboard.
My mum lives in a 1950's built ground floor flat and has a Worcester-Bosch Combi boiler situated in a cupboard in the kitchen. The boiler is regularly serviced and seems to work properly, it is fixed to an outside wall and has an external flu which works properly.
Unfortunately over the past year there seems to be an increasing condensation problem in the boiler cupboard. Quite a lot of mildew and damp has appeared. There is an external vent to prevent this sort of thing, but it doesn't seem to be particularly effective right now.
In fact there seems to be some kind of brown discharge coming out of the vent and staining the outside wall. The external vent is situated in a little alcove by a balcony, so it looks like it's in a corner. There is also some sort of pipe running to the flat above adjacent to the vent. This pipe also seems to be prone to condensation. I've attached a photo of the external wall.
What could be causing this? Nothing has changed in the flat, is it possible it's a slow leak from the upstairs flat that goes into the wall? Or could it be condensation from the section of ceiling above the vent? Or from the nearby pipe?
Any help would be greatly appreciated.
