I'm not sure these two things mix well. I have all-heart American Black Cherry flooring 8" x 12' planks. I want to install it as optimally as possible to protect it. I'd also like radiant floor heat.

I understand wide planks are temperamental. I will be glueing and nailing the cherry to a plywood subfloor. The heating lines would be under this 1" subfloor.

The floor will be quite massive and will resist temperature changes, which is a good thing, and I also would think good for the floor.

Anyone see a risk with in-floor heating this type of floor?

Thanks much!

put a floor over a product called warmboard, the recommended widest was 2 1/4. I was also told to do glue and nail but just chose nail as to not have the glue touch the pex, I think you would be ok.

Thanks. I'm at 7 1/2" width. If I do this, it will be from using something like Warmboard that has aluminum plates for distribution. If I have enough surface area of floor, I can keep it from exceeding 85F. The sun warms the floor more than that...

As long as I avoid the 110-120 temps I suspect I'd be OK.
