Re: [GBlist] radiant heat

Barbara & Chris -

I am looking at hydronic rather than electric radiant floor heating
systems. And yes, I've heard of Radiantec... starting about a week ago
when I began reading the archives for this list :-)  I've recently had a
nice chat with them and now need to send in my house info & plans so we
can take it to the next level.

There are plenty of companies that sell radiant system products. For
instance Slant Fin (of baseboard heat fame) at http://www.slantfin.com
has both wet & dry systems. Like many dry systems, the tubing is
threaded between the joists from below. Some companies like Stadler
Viega at http://www.stadlerviega.com have panel systems where you add
aluminum backed wood strips above the sub floor that form groves that
the tubing snaps into.

Radiantec suggested either working the tubing between the joists or
adding 1x_ sleepers above the sub floor, running the tubing in the air
space, and then flooring over that. This seems like it will use a bit
more wood than the fancy panel systems, but eliminates the aluminum and
costs less.

[these two web sites picked because they were the last two I visited...
I know little about either product!]
