Doesn’t this leave you just heating up the concrete block under the floor though?
I am in the same situation as @Stonehedge - minus the good insulation - storage heaters, vented cylinder, concrete slab.
I assume I will need to dig down, which sounds horrendous, get new cavity wall insulation (mine is ~30+ years old), and in the first place new windows…
Very interested in general on this topic, specially intrigued by @dbr’s boiler scheme plan!
t.o.-
I don’t know about wet underfloor heating to be honest; ours is an electrically heated pad in the bathroom which I guess is like an electric blanket.
I was just making the point that concrete flooring shouldn’t necessarily be a showstopper for wet underfloor heating, particularly if the plan is to gut and redo the place before moving in.
You make a good point though: concrete would be quite the heat sink.

You can easily rout (sp?) channels into a concrete floor, for wet underfloor heating. We relocated a run of heating pipes in the extended bit of our place (concrete floor, pipes in front of the skirting and wiring in trunking, both of which we didn’t like).
Good luck!
