All the words: radiant floor heat

8100 hits

I tried all variety of "radiant" "heat" etc... if you'll notice the
group names are posted too. That's how I found "sci.energy" however
none of the listings seem to be focused on one particular group or
list. Everything from "misc.consumers.house" to "rec.woodworking" is
showing activity. I was hoping to narrow it down given the specific
nature of my questions.
Cheers! Ian.
