We’ve learned over time that heat and air ducts in the floor weren’t really such a good idea.....

I prefer the piping of boiler water thru schedule 80 stainless piping with aluminum fins spaced 10" apart in the slab. It works fantastic.

In the summer, use a chiller to pipe the same water thru the pipes. Just not so cold as to make the floor sweat.
