I'm looking to install a radiant heating system on top of the concrete slab of my apartment. I'm not planning to use any insulation. I like the neighbor below me and why should he not benefit from a warm ceiling.
I was looking at SubRay and SmartTrac and can't figure out which one of the two products is better suited of my situation. The Watts website doesn't seem to provide complete information for both. What are the pros and cons of each, and the differences between them? Is SmartTrac replacing SubRay as a newer product?
