Hi John and Angela,
That looks fully professional.
The warm up time sounds equivalent to the hydronic floor heating in the house I used to live in.
In another thread someone suggested "magic carpet" which is a material that can be custom ordered in different sizes. They are even willing to cut holes for the dual pedestals for the dinette table. I believe they have an "under floor" product as well.
I've asked for a quote on some Magic Carpet for the (freezing) floor in my Class C. There is, alas, no basement to heat.
