You'll like floor heat. I've got it in my 27X54 shop and it works well. I've got 2 sections runs or sections, each having about 360 feet of 3/4 inch plastic pipe in the concrete. I ran a 4" floor and then laid the pipe and ran 2" concrete over it. Most of the newer systems here have the pipe laid on a sand bed and concrete run over it. My concrete over concrete was hard to work. It was slow to dry and get a good smooth finish. I would reccommend a floor that slopes to a drain. If you ever bring a vehicle in that has snow or ice under it this type of heat will melt it off and make a mess. My pipes are on 24" spacing, and I would reccommend that they be closer, probably 12-16 inch if you want to keep real warm in your area. I've got 2 thirty gallon water heaters and they have to run from Oct. to April continuosly to keep the place waarm. It takes a while to warm up that much cement, but it will stay warm quite a while if the system goes down. I think a small boiler is the best way to heat your water. Insulate well. You could ask around in your area, I would imagine that some of the farm implement shops would have floor heat and would be able to tell you where to get good info.

I,ve got floor heat in my house and love it..if you are in a cold climate I would recommend using 2"styrofoam and then lay down the tubing and pour you cement on that...better check local building codes because some will not allow water heaters as a source of heat..I use a gas boiler(exspensive water heater)..It maybe turns on 2 times a day if it's really cold...look at putting in some circulation pumps that continually pump the water through the floor..that will keep the run time of your heaters down...

Go to
I used to work for this company They build an outdoor woodburning stove that heats water and then pumps it into your home, shop,or both through a thermoplastic tubing. This tubing can be run under your concrete floors to heat them also. This unit is worth checking out.
