What a brilliantly helpful bunch! Thanks for that. It's an open vented system and there are actually 3 tanks in the loft. I might be wrong, but from my limited research is one perhaps an overflow tank? It is empty, but does appear to have held water in it fairly recently (see pic).

Hi folks
Wonder if anyone can give me any pointers. I'm very much a novice and have no real understanding of heating but am trying to make sense of what I have in my house.
