Wet underfloor heating genius needed

[Benway]

Planned extension in yellow, with underfloor heating, no issues.
Existing part of the house in green (but part of the new open plan extension) currently has a beam and block floor with 50mm screed.

What is the best way to incorporate underfloor heating in the green existing bit?

Cheers

Easiest plan would be not to do it surely if the finished floor level is the green bit.

The underfloor heating is planned as the only heat source for the room. Didn't really want to leave 1/3 of it "unheated".

Cheers.

Rdaiator.
Either that or you need a jack hammer genius.

NuHeat LoPro Max. You'll probably need to use this for the whole area though including the extension or you'll end up with it heating and cooling at different rates

Looks interesting, thanks.
I really would like to keep the extension as "standard" underfloor heating that heats up a large thermal mass rather then just the tiles above it..

So you're going to stage baseball games in your extension then?
