Any idea what caused this to wooden floor

Purely guesswork at the moment. Yes, of course it could be any of these things.

But until someone lifts these boards, I fear guesswork is all you have.

I'd have thought that 'waste' water would have caused an odour as well?

Yes, if it's part of the communal system, it should be covered by the building management's insurance. But, I'm pretty sure the making good of the floor would still come down to your contents' insurance - that's usually the way it works.

I think I'd still go at this by making an insurance claim, because they will almost certainly be needed to sort the effects of the leak in any case. Should they find it's been caused by part of the 'communal' plumbing system, then they will pass that part of the repair to them.

Pretty sure that's how it works, but you should have a good read of your policy.

On the 'pressure' issue, is it that high all of the time, or only when the system is hot and running? Has it required pressure 'top-ups' over the past while?

Thanks. 

The heating interface is checked annually by a company from the building, passed just last July. So I don’t really touch it or mess with it. 

Pressure is usually at 2.3 bars

I don't know much about the technicalities of UFH, so cannot comment whether 2.3bar is 'normal'. It seems high, tho' - it would be high for a radiator system. And the red pointer - usually the one to act as the setting guide - is at 1 bar.

Who tops it up? And why to 2.3 (or higher)?

Does it fluctuate?
