Help on cherry strip floor

[modernist]

I am in the mire! the underfloor heating people (water) say you can only have one layer of wood or the response time is too slow and the engineered floor people say you cannot lay it directly over the pipes.

I had put down 17mm flooring chipboard so as to be as thin as possible and intended to go for about 10mm engineered floor with 4mm of cherry on top for damage resistance. The thinnest I can find is 14mm with the 4mm top and I don't fancy 7mm with only 0.5mm of top veneer.

I am between the devil and the db sea! I think 17+14 will be too thick and 0.5 wont last in heavy traffic.

I had thought of quarter sawing cherry in say 65mm x 4mm strips, adding a t & g and gluing and/or stapling through the tongue onto the chipboard. this would give 21mm in total and the glue should allow a decent heat transfer. Any comments and thoughts on the glue would be most welcome.

not sure how helpful this is, but my mate installed ceramic tiles over underfloor heating, and it seems to work ok.

watching mr holmes in canada, he seems to lay the underfloor in a cement base, and then lay the strata over a thin sub.

That's it then, I'll go for it - thanks

surely, the reason for underfloor is just to take the chill off, not provide full heating???

years ago in holland they used to have like warm air ducts by the windows in many houses which were built without very deep foundations because of being alongside a canal. it just reduced the chill rather than being used like "proper" central heating.

I hope not, it's all we will have. I've done the calcs and 15mm pipes at 300mm ctrs at 60 deg C will keep us warm, providing it all pentrates the said multi-layer floor. I intend to run the heating for a couple of weeks to dry everything out before fitting the engineered laminate.

Anyone any thoughts on adhesive - I intend to use normal PVA
