I use this one - http://www.heater-store.com/HeatStar...ant-heater.htm - in my two car. Works very well.

I just ordered 1 of these for the basement. Hope it doesn't gas me out.

I would go with the electric unit that "tekheavy" posted or something similar. As mentioned earlier, fumes in a garage can get over whelming. It is a garage, and most likely you are going to be playing with Gas, brake clean, carb cleaner, spray paint, solvents, etc. Open flame heaters are not a good idea in those environments. I know that lots of people have, and do use them, including myself in the past, but It only takes 1 time.

my 2 cents

Believe it or not, my uncle heats his house with those units.

As with many garages, the unit that runs on 120v won't do it. I was lucky enough to have the chance to run 220 out to mine and got a nice 220 coil/fan unit left over from a job.
You will need some type of burner/heater, unfortunately. Lots of good suggestions already. I would use a vented unit.

It's hard to beat a used kero salamander. You ca run them on diesel, too.

Last winter I took my dad's ancient Knipco 75k BTU salamander that must be from the 1960s. Hadn't been run in two or more decades. I tore it down, went through everything, put it back together and fired it up. Works like a champ. No hard-to-find or expensive store-bought kero for me. I run diesel. Heats the lower portion of my 24x32 w/R-19 in walls and nothing in downstairs ceiling in a short time. Smell isn't too bad at all. I have a CO detector mounted on the wall and it never registers anything from this unit, which is odd.

Doesn't go through that much fuel, either.

I will often get the temps up with the torpedo, then maintain temps by running my 220 volt USA-made heater...made by King, I think, out of the Pacific Northwest somewhere. I like to avoid Chinese equipment whenever possible.

But Bull the smell is terrible and toxic.

I don't find the smell to be very strong.

Is it more toxic than burning kero?

You can crack a door or window to get fresh air in.

I never would have thought to burn diesel, but when I was going through that heater I read a bunch of stuff online and found that a lot of guys do it. Some of the newer heaters are marketed as being able to run on either kero or diesel.

I'm no expert, just a guy who found a cheap way not to be cold.

Ventilation is key,but I find the nox to much.Also get a co meter.
Insulate to the max.
I used electric years ago.
But I'm an old fart.

[AdamIsAdam]

I checked my panel. I can make room for a new 220 breaker. I'll go that route.

The smell was never anything much at all with my old gas burning ventless wall mounted units, but I didn't run them that much once the garage was warmed up because I did a good job insulating everything.. I even installed an R18 door. Ah, the good ol days.

I do have a CO/explosive gases combo meter plugged into a chest-height outlet. However, my understanding is that might be too high as CO settles down low...?

[Sirrotica]

I use one of these, but you need to have a supply of firewood to use one:

I have one electric radiant heater and 3 propane radiant heaters. The propane radiant heaters are 8,000-28,000 BTUs each and I have a 40,000 BTU Readdy Heater propane forced air heater. I used to have a 2,000 square foot pole barn and these heaters heated it nice. I use the Readdy Heater when working outside. I usually only use the electric radiant heater and one of the propane radiant heaters to make my garage warm. The others I may use if the temps are below zero.

Adam, I see you are on Long Island too. If you decide to go with the 220v model I have, feel free to stop by my house and see how mine works.

If you have windows in the garage, install storm windows over them. Even one of the plastic insulation kits will provide a dead-air space, which will decrease the heat loss.

The heat loss through glass is staggering. Regardless of what form of heat you choose, double (or better, triple) windows will significantly reduce the energy bill.

Just as a point of reference: my shop is 20 by 40 with no windows, 8 foot ceilings, R-18 insulation in the walls, and R-26 insulation in the ceiling. I have three 240v heaters of 3000 watts each. Turn them on at 6 A.M., and by 9 A.M. temperature is acceptable if the ambient is not less than 25 degrees F.

Jon.

Amen to that. My garage was built in 1922. That window does nothing but let light in and let heat out. That stretch plastic works quite well for what it is. The construction of my garage is so basic, that you can see the back of the siding, I staple some 6mil poly on the studs for the winter and it kinda does the same thing as the window treatment.

I'll PM you my contact info. Any guy with a Verdoro Green 68 is ok in my book

Propane can give 1 gallon per hour to your area. When shut off, and cooling, its like parking your car on the grass there is so much extra oxygen. ( FE02 happens...) ( rust)
Kero is better than diesel, but still has fumes, AND a lot of moisture as well, but nothing like Propane. Radiant better than flames on a gas.
The 220 electric unit WILL be THE most efficient unit at 97+% efficiency.
I have a Kero Salamander,and a radiant gas heater 30K BTU..The radiant gas heater worked well, not fast, but the moisture...
Now I heat with 22 MILLION BTU per ton Pennsylvania Anthracite coal.

I probably shouldn't even answer this question as it usually doesn't get very cold here. If you just want to heat a small area where you are working (like under the hood) the Halogen work lights put out quite a bit of heat and you get the added benefit of being able to see what you are working on.

You're right. You probably shouldn't have answered! LOL

I lived in San Antonio for a spell. You're more likely dealing with AC issues than heat in the garage most of the year. And for that we're sometimes jealous.

Seriously, a heat lamp really wouldn't do much when the entire garage is 30*. Plus, when working on the car I tend to be all over the garage (getting tools, going to the workbench, then on the cold cement floor, etc). But thanks for trying. Seriously.
