We've just bought a new place in Cornwall. Whilst looking in the roof above the bathroom I found the bits in the pic below. There's an expansion tank, a water tank, a pressure vessel and a disconnected expansion tank in the pic.
Any ideas what the red pressure vessel is and what it's for? Pressure reads just under 1bar not sure if it should be higher?
