Radiant heat placed in between floor joists from the crawlspace?

[rusty quoin]

1. The radiant heating that is run along the joists is heated water in plastic tubes.

It requires a whole system.

If you mean electric, they are layed over the subfloor. I thought of installing it, and still have the option to do it in my dining room which is still subfloor.

A bathroom is a perfect use for electric, in fact I will be redoing 2 baths, and most certainly will use it there... warm feet in the winter...ahhhh.

As far as I know, Frank Lloyd Wright was the first to use such a system. He found out that if you heated objects that people are in contact with, like floors, there is less a need to heat open spaces.

In the early 2000s the guy I worked for along with his plumber, used radiant floor heating a lot. It was a hot water system, superior to forced air, like radiators of the past (forced air dries things out including you).

But I say go for electric floor radiant heat in your bath, if that's the system you are talking about.
