Retrofit UFH for Suspended Floor

[n30_mkii]

So the property we are buying has suspended floors for every room downstairs other than the kitchen, which is a solid floor. The house is having some renovation work done so a full rewire and new plumbing. We've decided to stay with radiators upstairs but want to install wet under floor heating downstairs.

So the initial plan was to lift the suspended floor floorboards and then insulate between the joists with either celotex or possibly a natural wool (still to decide). I was then planning on perhaps installing something like omnie torfloor which becomes the structural floor, but then we would need to use an overlay system in the kitchen leading to a height difference between the kitchen and other rooms. The alternative I'm exploring is to use an overlay system which can be overlaid over both solid and floorboards instead to give a consistent level.

I'm just wondering if anyone else has undergone a similar piece of work and which approach and type of system you used. Ceilings are fairly high downstairs, and ill be replacing all internal doors, so a small build up isn't the end of the world.

Thanks for any responses

I'll start a different thread potentially around best approach to insulation

Take a look at Prowarm I'm pretty sure their 20mm/16mm overlay boards can be put on suspended floor.

What finish are you putting on the floors? Over boarding can take Laminate/timber directly on top.

Likely laminate or LVT I think. The wife would've liked carpet in the living room, but I think a hard finish will be easier option

Did you decide on what to do?

Still working through it, but I've dug out the solid kitchen floor and going for UFH buried in the screed layer with 150mm insulation under it. For the other rooms (suspended) i'm going with 100mm insualtion and the omnie TorBoard 2 system. Going to a pita to fit it, but hopefully will be good once it's done. I'm just finishing up the design with them before ordering. The system isn't cheap though!

I'm potentially going for a TorBoard 2 system upstairs in my house and a screed system in the new concrete base.
I had a long chat with the Omnie people today and should have a quote in the next few days, also had another from Nu-Heat as well
