So, a couple of times in TOH magazine, I've seen them mention radiant heating panels hung from a ceiling or mounted to a wall as a good solution for heating a woodworking shop or garage. And while they have mentioned brands and manufacturers, never once have them noted how to actually BUY said items. They are supposedly as easy to install as flourescent lighting (which I have done). I have searched online, and I can find places where people talk about installing them, but again, no one says where to buy them. I have NO idea how much these cost, how to calculate how many or what size I would need, etc, etc. Do I call a contractor and offer to just buy the materials from them? Is there somewhere I can order some? Have any of you used/installed these?
