Can I use thermal evacuated tubing with your radiant AIR system in a raft slab?
The project is in Thornbury Ontario which is Georgian Bay. I am an architect, interested in combining the Legalett system with either a thermal solar panel or thermal tubing. I need advice and a better idea of what your services are. I watched a video with Mike Reynolds from your company. I have a few structural questions about the raft slab as well.
Legalett is an independent company, we just feature it here as we do other systems that we like, and so far we have not found any other company that does infloor heating with air tubes such as this. But there are a lot of advantages, you can see here on our page comparing the advantages of air heated radiant floors to liquid.
The air heated floors provided by Legalett circulate air in a closed loop system rather than liquid, but the coil that heats the air can be water or electric. So you can power it the same way you would power a hydronic system, and what you suggesting would work fine. The liquid coils in the heater box need to be fed by a boiler, and just like hydronic floors, and you could feed that with thermal solar collectors, an air-to-water heat pump, or a geothermal system.
