Underfloor Heating , little different design to normal.

[FloorSkills]

Hi, I run a flooring training centre. We also do a lot of testing for manufacturers , court cases etc. At the moment i have use of test labs for testing. However we would like to bring testing in house at the training centre.

What i require is a (i think) wet underfloor heating system. The reason why i say 'wet' is the same concrete slab will be constantly ground with diamond grinders so i need a heating system to heat the concrete that can be buried deep in the slab. We are thinking at least 3" below surface. I understand that this would not be the most effecient design in the world but it wont be used to heat the room but for testing, we simply need to heat the concrete slab.

So what i need is -

-Heating system to heat slab with pipes deep
-Be able to run temp (surface temp of concrete) above standards, need it to hit 40c +
-We have no gas boiler, Electric boiler maybe? Size of area will be 6sq'm.
-I need to be able to raise or lower the concrete temperature, not by room temp, so controller sender needs to be in concrete.
-It does not matter if it takes 5-10 hours + to heat up, as long as it can reach high temps.

Your thoughts at first ?

Thanks in advance.

Just a fairly standard manifold, pump station, mixer and 16mm pipe buried as deep as needed, make sure there's plenty of insulation under and around the slab to keep the heat where it needs to be.

Control could be as simple as a remote phial stat in a pocket cast into the floor, or any of the remote sensing stats available.

An electric boiler would do it if sized right, but be dear to run.
