Can also be found there, Ed. I hope you find what you need. 750,000 people per year, go there for advice on radiant heating. To find the closest, qualified radiant contractor, to you, check out the new section at www.heatinghelp.com. It's called "Find a contractor" & is at the top of the list, at left of the home page. Good luck, Ed, and anyone else needing "Heatinghelp". Regards, Brian.
