I'm using radiant tube heat, like Rogers, in my new shop and ceiling fans to push the heat down.
Bob - any pictures? How'd you vent the ends? That's what is holding me up, whether I want to vent through the sides, or the roof. Mine can run unvented, but with the possibility of fumes, I think I want it vented...
Haven't gotten the heating system in yet, heck, they haven't built the building yet! The developer has promised to have it done on schedule by the end of August, I don't think so. The lot is still just a empty field of scraped dirt. I've signed papers and have earnest money in an escrow account so I'm not too worried, yet. I'm in no hurry, well not too much of hurry, my down payment money for the loan is sitting in the bank earning interest for me, not much, but it's still making a little.
Bob, at work, we use Vantage II radiant tube heat and there's no need for a fan, lol. Once the objects in the room get warm, they all hold the heat in. However, if you plan on moving stuff in and out alot during winter, that might change.
My current garage is about ready to fall down, and may put a kink in my plans this year and the next....atleast until I get the old mobile home torn down and outta here. Meanwhile I still trod on with the bills, gas prices, and Tbird project. In hindsight, I shoulda just tore the old garage down and started over when I bought the place. Then bought all the tools, and then start on the '48. I have moments where I feel I have too many projects in Havi's Truck Disneyland.

I know you guys are a little colder than we are, but probalby not too much, average. We have the radiant on the closed dock at work, trucks opening and closing doors all night long, and one single-tube the length keeps up just fine. As you said, the fan isn't necessary, the object get warm, then keep the air warm. Even if it gets a bit cool, as soon as the doors are closed, it's almost instantly warm again - not like forced air, where you have to re-heat all the air again. I wouldn't go with any other heat!
We are vented through the side wall at work - how's yours vented, Scott? I just really don't like the idea of breaching the roof! If I had had the builder install, then THEY would have been responsible for any leaks, but since it's me....
I'm not sure how they are going to vent mine. The developer hadn't thought about radiant heat until I told him I wanted it. He normally installs forced air which I really don't like. He talked to his heating contractor about the radiant heat and the guy sized the correct system for the size of the building.
Forced air is the only type I have ever had. It does OK but on really cold days it's constantly kicking on and off and tends to dry everything out, including my respiratory system and you have to stand in front of it to get enough heat. Thanks to Roger I never really thought about radiant heat until I stopped by a few months ago. The building I am buying is a cookie cutter package and the ceiling fans come with it, along with the forced air heat. I just figured if the fans don't do much to conserve heat they'd be nice in the summer to keep air moving in the shop and keep it a little cooler feeling.
I have a 70 x 100 x 14 tall metal building at work. There are two 45 ft long tube radiant heaters in it. They are great. They run on natural gas. There is a small blower sucking on the end of the tube, opposite from the burner. It just blows into the building. Have had them for several years and have never smelled anything, nor had any problems. I have another building, where my truck is, that is 40 x 80 x 14 and it has one 40 ft tube in it. Heats the place from 40 to 72 in about 45 min. When you open the doors you don't loose all of the heat because the infrared heats objects not air. Sure makes the floor nice to lay on. They are also much cheaper to run than the forced air I used to have.
Don - how about the intake side? I can put a vent, similar to a dryer vent, and vent inside, plus I can vent from the outside, or the inside, but in paint environments, they highly recommend outside intake. But, I would probably not be painting, at least seriously, in the winter, anyway...
Roger, VANTAGE ® II Infrared Heater
This is similar to the ones I have. Mine are not vented. I have enough air coming into the building to meet the requirements for non vented. You can look at the installation manual, part two, for this heater and see the recommendations on venting.
