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.
