Garage space heaters

[T.G]

Mark,

Going to something much more powerful than a 1500W might not be doable unless you have a 20-amp circuit in your garage. 15A breakers are standard for residential construction and that maxes just shy of 1800W @ 120V, but by NEC, you aren't supposed to load to 100% so you are stuck around 1500.

I've had decent luck with "milk house" style heaters. They don't oscillate at all, but they are compact, more durable than the plastic towers and IMO safer than the dish heaters. The dish heaters are probably the most efficient for single direction heating, but I personally am not crazy about them due to the often chinsy construction and safety issues with an exposed coil.

I had one of those big electric oil radiators in my garage. Worked well when the door is closed, not so much when the rollup was open. :/
