When I did mine Radiantec told me the size of water heater. They gave me the option of the water heater a commercial 75,000btu or the Polaris. Radiantec worked up all of the calulations.
As for the tubing in the floor make sure the stuff that Home Cheapo sells meets code. you may need to have...
I have the Polaris 34 gallon 100,000 btu natual gas. It is heating my 2000 sq.ft. garage. The tag says 96.7% efficent. It will heat the water about 4 times faster that a normal water heater it is very impressive but expensive. I hope the high efficency will make the cost worth it.
I just got my system up and running. I used Radiantec.com and also used a Polaris water heater. All I can say is it is great and they were very helpful. My contact at Radiantec was Don Vance. You can read their web sit and get all of the info you need and if you have questions they will explain...
I have a 200' run going to my garage for my 100,000 btu water heater they used the same stuff that nissantech used. I would have a quaified plumber do it. It is worth the extra money to make sure you don't go boom.

I agree about not sealing out mice, they will find a way in. The bi-fold doors I have use have had a rubber gasket on the bottom tha seals against a asphalt or concrete floor. These are not a type of door that you would install your self. When you get some bids they should be able to tell you...
I have used these for many years in aircraft hangers. They take about a minute to open fully. I have never had a problem with them. What else would like to know?

I purchased my radiant heat from radiantec. They were great to deal with. Very helpful. I would have no problem referring them to anyone. This will be my first winter using it so I can't tell you how well it works. I just followed the directions that are on the web site and the info that they...
Web site works for me. I installed this in the garage I am building. Very nice products. Easy to install. If you are thinking about buying it check out there shipping cost. I told them I was canceling the order because of the shipping cost and they discounted the price.
