I had an outlet installed in my new garage just for that reason. MD has deregulated so our rates are just nuts. Last year I went with a 30k BTU propone heater. It heated up pretty quick and only used less than 2 tanks, costing me $40 for the whole winter. I am rarely out there for more than 5 hours at a time and it doesn't run continously so I have never noticed any problems.

I bought an electric heater from Grainger (18000) BTU, only catch was, (and I was avoiding)I had to install a 240v/30 outlet plus a 30 amp breaker. Now the garage stays at about 55 degrees while I'm not working out there and I can turn the thermostat up and get it to stay at 65 degrees while working. It only took 30 minutes to move from 45 to 60 degrees. Just wanted to follow-up to anyone who is still having problems.
I need to do something like this. My garage is 24x40 and insulted so I'm wondering what size I would need to heat it kind of like yours. 18000 BTU's enough? Thanks.
Gas appliances are generally rated in BTU"s per Hour, but electric heaters are usually rated in Kilowatts. 18,000 BTUH is approx. 5kw.
My garage is also 24'x 40' (with 12.5' ceilings) and it well insulated with two insulated OH doors, one man door and 6 double pane windows.
I am currently using a 5kw construction heater (similar to that described by the OP) and it has no problem keeping my shop at the desired 55 deg F with an outdoor ambient of 5 deg F.
That having been said, 5kw is too small and my permanent heater is 10kw. Check this out;

Look up BTU (British thermal units) and figure out how many square feet of space You have. Then You can figure out how big of a heater or what btu You need. BTU= the amount of energy it takes to change 1 square foot of space 1 degree. IIRC ? anyway, there are btu calculators available, just do a search.

Got a HOT DAWG and have no regrets.
Not a good thing for a dusty shop though as the fan REALYY moves air !!!
Those Hot Dawg's are nice, very compact and can be mounted what 1" from the ceiling?
But I do some painting in my shop that's why I like radiant gas heat. It's silent and sturs no dust up when I fire it up to help dry my paint. And when I open the garage door to move trucks around the heat stays in the shop.

Actually, it's the amount of energy required to raise one lb of water 1 degree Fahrenheit.
There are many variables to take into account to do a proper heat loss calculation, but I posted a link to a simple calculator above that will work for this.

Actually, all three electric heaters I purchased were rated in BTU'S not kwatts. Its good to compare BTUS's when comparing propane with electric. The It dosent matter what it stands for as long as you know that 18000 BTU's is rated to heat a 500 square foot space. I leaned this the hard way by going cheap at first with the 5000 BTU heaters. It wasnt until I purchased the 18000 BTU propane heater that I realized the difference in heating potential. My garage is only a 20 x 20 = 400 square feet but I oversized the heater slightly so it wouldn't run as often. Like I said I went to three different stores, and returned three heaters until I got the right match. this heater is only 16" by 12" by 12". My garage is insulated as well. However your garage is 960 square feet. Its easy to figure out what heater size you need just go to the grainger web site and read the descriptions. They will tell how many BTU's the heaters are and what size garage they will heat. You might want to get two smaller units and heat from opposite directions.

I have a Hot Dawg propane in my shop, it is very nice and heats my 30' x 48' shop quickly. I beleive my unit is either 60K or 80K.

When I lived in Michigan, I used a 150,00 BTU kerosene heater (torpedo type). It warmed the shop up nicely, but there was always that smell and quite a bit of noise. It also required a fresh air supply, so you couldn't close up the shop tightly or there would be carbon monoxide dangers. I am seriously considering one of the 99.9% propane units that are now available.

Im building this  Waste Oil Heater Plans Transform a 55 gallon drum & 100# propane tank into Free Heat from a Zero Smoke Waste Oil Heater you can build in about 2 weeks. * NO PANS TO CLEAN OUT * NO FILTERS TO CHANGE * NO FUEL NOZZLES TO PLUG * NO EXPENSIVE PARTS OR MAINTENANCE How is this heater different than other waste oil heaters? Most waste oil heaters on the market today are engineered to be either a Spray Gun type or a Pot Burner. Pot burners are just what they sound like. It's basically an oil fire contained within a pan or pot. These are very dirty devices and create lots of soot and smoke. Spray gun types are a more efficient design because atomizing the fuel before igniting it results in a much cleaner burn and more heat output. The problem is the high pressure fuel pumps and tiny fuel spray nozzles that plug up due to the particles and contaminants present in waste oils. Our heater atomizes the fuel before igniting it but does not use a high pressure pump or fuel nozzle, there is nothing to plug up and the design eleminates the need for expensive filter changes. · Heating Capacity: 70,000 Btu’s - 200,000 Btu’s (with adjustable fuel feed) · Fuel Consumption: 0.6 to 2 gallons per hour · Fuels: -Waste Motor Oil -Waste Vegetable Oil -Transmission and Hydraulic Oils -Mineral Spirits -Machine Cutting Oils -Synthetic Oils -Gear Oils. -BioDiesel or Fuel Oil at any ratio together or separately. · Dimensions: 30” Diameter x 68" Tall + Fuel Tank of your choice. · Weight: ~250 Lbs. (Without Fuel Tank). · Electrical: 110 VAC / 15 Amp Circuit. · Compressed Air: Less than 0.5 CFM @ 80psi · Controls: Manual Ignition and Shutdown · Construction: Commonly available materials

http://www.ultimategarageheater.com/garage-heater-calculator.php
you will note that your 400sq ft. garage (insulated) needs about 4.4kw (approximately 15,000 BTUH) for a 60 deg F temperature change.
2) All commercial electric heaters are rated in KW, but no matter as long as you realize that 3414 BTUH = 1kw it's simple math to go back and forth.
3) ratings per square foot are pretty rudimentary (even more so than the simple calculator I linked above) and doesn't take into account ceiling height, insulation, # and type of doors and windows, exposure, etc, etc.
Just my  as I do this for a living.

My dad insulated his single car garage and didn't have much money left over to spend on a heater so he bought a 230v 18,000BTU portable contstruction heater. These past few days have been about the coldest it ever gets here and that heater gets the garage up to 50-55F so it's not bad at all, not super hot but very workable in a sweater and an extra pair of pants. He said some guru calculated the cost of that thing to be about 23 cents an hour. And you're only heating it while you're working in there so I don't think he'd ever spend more than 15 bucks a month heating that garage.
This is exactly what I am using,230V/30A 18000 BTU portable and it does seem to be working well. I dont have any propane to buy, no poisonous gases,no kerosene to buy or smell. I just set the thermostat, and it works by itself. With the propane heater that I already returned, the propane canisters cost me 6 dollars for 2 one lb cans, which last for 6 hours total. So I dont think the electric will be that much more to operate. The biggest obstacle was installing the breaker, 10ga wire, and 30A receptacle. Thankfully I have some electrical experience and was able to install this stuff myself in about 2.5 hours. Still a pain though, crawling in the garage attic in 35 degrees.
