Buying advice: space heaters

  1. Ceramic suits quick heat in small rooms. Oil-filled suits bedrooms and all-day heat. Infrared suits warming a person at a desk.
  2. A 1,500 W heater typically warms around 150 square feet as primary heat. Insulation and ceilings change that.
  3. A digital thermostat cycles the heater to hold a temperature and avoids overheating the room.
  4. Look for tip-over and overheat shutoff, cool-touch housing and a UL or ETL listing.
  5. Plug directly into a wall outlet, not an extension cord or power strip, and keep at least 3 feet clear around the heater.

Is it safe to run an electric space heater in a garage?

Yes, with a few precautions. Keep the heater at least 3 feet from anything flammable including gas cans, paper, and stored fuel. Never run a heater on an extension cord rated below the heater's amperage, and never leave it running unattended overnight in a garage where flammable materials are stored. Standard 1500W electric heaters are safe for garage use when placed on a stable, level surface with clear space around them.

Do space heaters work well in an unheated garage below 50°F?

A 1500W electric heater can noticeably warm the immediate area around a workbench in a cold garage, but it won't raise the temperature of an entire two-car garage the way it would a small bedroom. Insulation, garage door seals, and ceiling height all affect performance. Expect a space heater to make a workspace tolerable to work in, not to bring a whole garage up to living-room temperature.
