Do I have enough power?

Do I have enough power to add a G73 Electric heater (30A 240V)?

I have 2AWG feeding my Garage Panel (100A). I also have the following circuits:

4-15A wall mounted outlet circuits
1-15A Lighting circuit (8x 2 bulb 4ft)(600W on 4 switches)
1-15A Garage door opener circuit
1-15A attic/hoist outlet circuit
1-20A 240V compressor circuit
1-20A 240V welder circuit (technically 40A as an intermittant load)
1-20A 240V AC (future) circuit for a a split AC system.

My garage is 28x24 (672sqft), with R13 walls and a combination of R6 (under attic floor) and R18 blown in on the roof), and is in KY with an avg winter temp of 25F(sometimes it will hit 0).

Realistically I can see the largest draw being the compressor, lights, and a plasma cutter (20A) at any single time.

Do I have enough power to realistically power a G73 electric heater based on the above loads (30A 240V). Is the G73 a good option?

I would bring the temp up in the garage quickly with a Kerosene heater, but the goal would be once its up to a decent temp (say 55-60) to only use the electric.

Thoughts?

I don't see a problem. Just how often will you be welding continuously, runnning the air compressor continuously, and running the heater at the same time? And, if you did, you still are drawing only 70 amps on your 100amp box.

I think you'll be fine.

8 out the 10 voices in my head are telling me that you should go for it....

You can use that heater and still have power to spare,should be no problem.

I have less feed and more circuits than you and run a G73 with no problems.

Thanks for the validation guys.......I really didn't want to buy a LPG tank and a gas heater if I could avoid it.

EVEN if there WASNT enough power on a 100A service, I always run my heater at a minimum when not out there then when I want to work, I turn it up to the heat I want it at, and go back in for a coffee. 15-20 min is good to go, lights not flickerin etc. and the heater runs at its minimal to maintain heat.

Oh so much how do I want infloor heat!
