> 3. Especially in a humid environment like the uk, you can end up with condensation and damp issues, which you really don’t want in an underfloor slab install

You only end up with condensation issues, if you cool below the dew point.

Here in very humid Singapore our dew point is typically at about 24-26C. If you set your aircon to no less than 26C here, you never have any problems with condensation.

(Any old weather reporting website or app will tell the dew point. Apparently right now as I am writing this comments, it's 12C in London.)
