My wife wanted to have a garage built that attached to the house. I told her not one that I’d be working in. I weld and use cutting torches. It’s one thing to burn the garage down. It’s another to burn the house down. She’d really be pissed if I did that…and she don’t hardly ever get mad at me. We ain’t going down that road.

I already have a concrete pad that will end up being right behind my pole barn so I’m going to make good use of it and build a compressor room on it. Try to keep as much clutter out of the main building as I can.

PICTURES please and thank you.
I’ll have to try and figure that out. I’m extremely electronically challenged as my son says. Every time I ask him for help with the computer or my phone, he tells me it’s just easier to change the subject. To think I gave him my name!

Well I was telling our two German Shepherds and Lab about the project. That their fenced in part of the yard is going to more then double because it’s going to go around most of the pole barn. They seem pleased.
Plus when we’re in it they’ll get to come and go as they please…which means they’ll be in it with us. My big GSD has a car tire he carries around. Guess I’ll have to hang any good tires we’ll have up.
So this really will be fun for the whole family!

Had a buddy in Minnesota who built a shop for his transmission business and used propane radiant heat and loved it. Heats the floor and whatever is in the shop and avoids loosing all the warm air when an overhead door is opened. Just thought I’d throw it out for folks to consider.
We are building a house and I’m dreaming of the day when I can build a shop. Already have a good idea of what I’ll need including a 3/4 bathroom and floor drains.

Hey Buck, my friend has a body shop, his building is huge compared to what I’m building. His paint both alone is probably more then half the size of mine and it only takes up a faction of his floor space. He has radiant heat and it does work really well.
Thanks, NYH1.
Yeh, in Minnesota we pay attention to heating and insulation. In-floor radiant is ideal. When I built my workshop, I put the tubing in the floor, just in case. Finally hooked it up to a natural gas boiler about 5-6 years later. I’m glad I had the option. Wood is, eventually, a pain. I like being able to always keep the shop at 50 degrees and turn it up only when I’m in there. I also like that it doesn’t blow dust around, there’s not soot on the walls, and I especially like that I don’t have to chop wood and keep a furnace stoked. The thermostat is remote…just pull it up on the phone and tell the garage to be at 70 degrees when I get out there.
I appreciate all the replies and suggestions. I’m not going to have the concrete floor poured until the spring. So I have time to think about different heating systems to complement the woodstove. Thanks guys.
Happy Thanksgiving, NYH1.
I had a custom home built this year, which we are now in. My garage is 1500 sqft, nothing fancy but twice the size of our last garage. I had it fully insulated R-15, but declined to add a heater of some kind. I will say this, the garage in these cold Colorado mornings is 20* warmer than the outside. That is very nice, but when it is -10*, 10* isn’t really that nice lol. I wish I had done either a space heater, or radiant floor heating. Too late now as far as the floor goes…
Just last week I got some bids to install heat for our 750 sq ft attached garage. $1900 for a 60,000 btu natural gas ceiling-mounted heater. The garage was insulated R21 when we built the house but never heated. I had the floor finished this past summer using polyurea/polyaspartic and now it’s pretty usable even in the winter. My wife won’t me heat the garage on an ad hoc basis using the salamander because noise and kerosene smell. Natural gas it is.
My point if you install the floor heat tubing it’s there for future use also you can tie it into a wood fired boiler or propane if u desire at a later date. Best of luck on whatever rout you choose.
I was told to insulate under the concrete to do it right, as well. Doing those things now will not add too much to the cost up front, if you do it yourself, and there ain’t much to those parts.
Insulation under the slab is important. Without under slab insulation you are heating a portion of the ground as well. How much really depends on the temperature of the soil. With insulation under it, the heat is used properly radiating from the slab inside the insulated building. I’m a big supporter of insulating under a slab in cold climates regardless of what heating system is used.
