I've had this infrared lamp setup for a few years now, and I was just out working on the plane thinking about how much having heat in the garage in the winter has done for my project. My build used to slow down a lot in the winter. It was just hard to get up the motivation to go out to an unheated garage where it was 30 degrees and handle cold metal with bare hands (don't get all snarky - I grew up on a ranch at 9000 feet up in the Rockies and spent most of my winters laying in the snow fixing equipment in sub zero temperatures. I already have that badge, so now I like a little comfort! 
).
I first tried a propane heater, but it would take a looong time to heat the garage up to the point where the metal wasn't absolutely ice cold. My dad heard my cry and bought me this infrared heater for Christmas one year. I put in a new 220v outlet and made a super fancy mobile mount out of my old wing stands. Man oh man, does this thing make a difference! Since it's infrared and it just heats up the objects it hits, there's no need to wait hours for the garage to heat up. Once I plug it in, the carpet on the workbench under it is warm to the touch in less than a minute. Any metal in a fairly wide swath of the beam heats up as well - not hot, but warm enough that it's easy to handle. The one downside is that the infrared mostly just bounces off the shiny aluminum, although if there's primer or paint on a surface, the heat is absorbed. This particular unit has a fairly large effective area and heats up most of the work area.
I rarely keep the unit running the entire time I'm working because it gets warm enough that I have to lose layers of clothes. If you don't have a heated garage, or like me have two big uninsulated doors that make heating the air in the garage a losing proposition, I'd highly recommend getting an infrared heater. This has been a game changer for me.
