What's the Best Way to Heat a 30' X 30' Shop With 10' Walls?

I am going to build a new shop and I’m hoping that I can build it 30’ x 30’ x 10’ walls. I was wondering what would be the best way to heat it. We live 40 miles north of Atlanta. Our winters are not harsh but at times we have moderately low temperatures and it certainly dips down in the 20’s and 30’s at night frequently. I would like to keep the shop 60 degrees in the winter if it’s practical. We do have a 1000 gallon underground propane tank. However, I’m not sure at all about having an open flame heating source.

Thanks in advance for whatever advice you can give.

Seal up any air holes if you got them and try one of those radiator type electric heaters. I use on in my shop and it never gets below 60. I live in Kansas City.

If wood for burning is easy to get, I would definitely add a wood burning stove, you would not have to use
it when spraying finish or having combustible materials in the air, but it could be used a lot of the time for not
too much cost. A friend has a shop about the same size, and he used pex hose inbeded in sand, then poured
the concrete over that. A local plumbing shop was able to help him set it up with the required planning and
setup. The heat for it is produce by a large hotwater heater with a thermostat controlling the heater and a
pump system. You have to fill the unit with a special antifreeze mixture, but it is economical to use and that
floor heat makes it a great shop to work in, so much so that I have to be sure that I am not a pest about
getting over there.

What about one of these. I think The Wood Whisperer installed something similar in his new shop.

Russell, is it the type that heats oil or does it heat water? I don’t know much about them. At the plant we had one outside wood burning heater that heated water and it had a pump that circulated the water to a radiator with a fan but it heated a bigger size room than 30×30. It was pretty expensive but cheap to operate if you had wood to burn.

I would suggest a wall-mounted or ceiling-hung propane heater. They are ventless and come in various sizes. You could also get an Eden-pure or similar electric heater. Both would do the job and come in various sizes but since you have propane, that’s what I would go with.
I live in NW Virginia and I have a 16×24 with 10’ ceiling and I use a basic propane heater and it does me fine. The temps here easily get in the teens.

PS—-I generate a LOT of dust and have never had any problems at all with the propane heater element I use.

wood stove is still the best i have found
one with a little fan to push the heat around
and sealed doors

some ceiling fans to set on low
to bring the heat down

with a decent dust filter system
air born dust is not a real problem
just have a sealed spray booth apart
if you do spraying (like lacquer’s)

my last shop was twice that size
with a wood stove and had a ceiling propane heater
on a thermostat
would come on from time to time
to hold the temp at a reasonable setting
but not used to much as gas is costly
and electric is too
for 24/7 use

and nothing help’s our aging bodies
like wood heat
it actually gets rid of the moisture
whereas propane makes moisture
as it burns

It’s oil filled. A lot of heat comes off it so I try and use that heat more efficiently than just letting it fly off into the air. I have a 4×4 bench I keep it under so it heats the surface of the bench and that helps heat the room. I do have one heater vent in the room but it only seems to serve as something to move air around. I have leaky garage doors.

I built my 25’x50’ shop a few years ago and I put in infloor heating. Best thing ever. I heat it with a propane boiler which pulls air from outside to burn so there is no open flame inside.It is 60 degrees in my shop all winter and I’m in Ontario Canada with much colder winter than you have.You can do this yourself. I did mine and it’s not difficult at all. You could use a hot water tank to heat the water.That works very well. I find it’s a lot easier on your legs to work on the warm cement floor all day.

Number one Charles is insulation, after that the guys have given a wack of great heat source soultions.
It’s suprizing how long a warm shop will stay that way if there’s proper insuation and venting..even from a days solar.

David, if I set up a spray room I will use only water based because of insurance. The insurance might be a killer on an inside wood burning stove – I’m not sure where that stands. At the plant we actually had a large wood burning stove that had a fan inside the air compartment that heated a 7000 sq ft room inside the plant. There was no woodworking equipment in that room.

Gus, one of those outside wood burning furnaces that heat and circulates water might work for that.

botanist, I saw that video of a tour of his shop. Now I remember that unit. Thanks, I’ll check on it.

I grew up in a home that used propane. It produces a lot of moisture. Is there no problem with that? Some of you guys that use propane out there….....no moisture??

Jay and sandblast guy, the propane tank will be less than 50 feet from the shop.

”The insurance might be a killer on an inside wood burning stove ”

I dont get it… If the insurance companies dont have issues with a wood-burning fireplace in your home, why woud they have an issue with a wood-burning stove in a shop? A lot of fireplaces in homes have nothing more than a mesh screen in front of an open flame. A wood burning stove (like a buckstove) is usually an enclosed box with the fire inside, radiating the heat

It’s not like you’re going to build a little teepee of logs and light ‘em on fire in the middle of your shop floor :-)
