I got a 3000W electric heater and installed it in the ceiling of my garage. Fortunately, the main electrical panel is along that same wall in the garage. So I have a 30A 220V breaker feeding power to the heater. I decided to do some redneck engineering and used a baseboard heater thermostat to allow me to turn on and off the heater from ground level. It's also nice I can set the temperature and forget it. The heater has a fan to blow the air through the heating elements. It can warm up my 2 car garage in the dead of winter within about 10 to 15 minutes.
