Heated Shop Floor

[RayDiers]

Have a look at this site http://www.hahsa.com . They have an outdoor heating unit the uses 15tons of sand to even out the heat. You also burn at max temp reducing the amout of smoke when hot water is not being called for.

I have wirsbo heat in my garage, my full basement, sidewalk, porch, and my two upper bath rooms. I just love it. I keep my garage at 50 and I can go out there and lay on the floor to work on things in my Tshirt. Attached are some of my pictures.

I also have a friend that built a 40X60 shop. we put wirsbo tubing down and we use a 50 gal hot water heater to heat the shop. the shop has a 16ft ceiling to it and the 48,000 btu's heats it just fine in minnesota.

For those of you that are going to tie it to a wood burner. Please make sure you read all you can about wood burner boilers. Dump zones are very critical. You can destroy your concrete and the tubing with too hot of water. the lower the water temperature the more even the heat is. have the right amount of pumps also.

Murph,
How large was your slap? What about expansion joints? Can you cut them in after pour? I'm still planning my shop and would like floor heat also. The floor plan is 28' by 40' so I know there has to be some expansion joints, just not sure how to design them in.

Dave,

I would have to measure what it actually is. My basement floor is about 2450 square feet, no expansion joints. My garage is a larger than 3 car garage, not as big as 4 car though and there is not expansion joints in there either. I have seen some really large installations where there was expansion joints, however, I am sure they only cut a little ways into the concrete. I am not a concrete guy so I can't be positive about that. I think, six inches of concrete and you must keep the pipe tied down so it won't float and then you should be able to cut the concrete an inch or so.
