I know there have been a number of posts regarding this topic, however I thought I may as well ask again.
I'm not very technical but as far as I can see we have the following:
A two storey house
An Ideal boiler on the ground floor
A hot water cylinder on the ground floor with an expansion tank on top of it (a combined cylinder I think)
A further expansion tank in the roof space, I'm not sure what this is for.
A pump of some description adjacent to the hot water cylinder.
A Zone Valve
The house used to be two flats so the plumbing is very messy.
We went on holiday for a week last week, and by Thursday we had a call from the neighbour to say our overflow was leaking warm water from the expansion tank above the hot water cylinder. When we got back and checked, the water level in the expansion tank was very high, and the water was warm. Once we has used some water the level dropped back down to normal and has stayed there since. We left the heating on for a few hours a day whilst we were away.
Does anyone know what might have caused this? The main problem is the cylinder and expansion tank are built into a cupboard so the only way to see in is via a mirror and a torch, which isn't helpful. I would just like an idea as to what it might be, as we will need to remove half the bathroom to get to it and do any major repairs.
