Electric Garage Heaters

Our Products: Room Heaters > Electric Garage Heaters
Electric garage heaters   Electric garage heaters are larger and more powerful than a standard plug in space heater. An electric heater is designed to heat a large space quickly. Because your garage has large overhead doors, you have two problems to deal with. The door opening and all the heat is lost in a few moments, and the other is the large door are so poorly insulated. The average garage has two to three outside walls and higher than average ceiling heights, and these walls may or may not be well insulated.
   We designed this page for an easier shopping experience; we pre-selected the correct electric heater by size of your room / garage. We started with average 1 car garage or a 400 to 500 square foot space. This garage is well insulated with an 8 foot insulated ceiling. If the outside air is 10°F this heater should be able to raise the indoor room temperature by 60°F. This will give us an indoor temperature of 70°F, if your garage larger than this example please visit our 1 car garage sizing chart page. If you have a 2, 3 or even a 4 car garage please scroll down for your heaters that fit your garage size.
    Our electric garage heaters are large residential / commercial grade unit heaters. A unit heater is an oversize heating element with a power fan that only runs on 240 volts. We didn’t select any 120 volt models because as a rule 1,500 watts isn’t enough heat for most garages.

What you need to start:

  • Enough power on your circuit breaker to handle the larger amperages that this type is heater requires.
  • A requires a dedicated wire from the circuit breaker to this garage heater, by code it shouldn’t share power with another device.
  • Do you want a unit mounted thermostat or wall mounted thermostat, wall thermostat take more time to wire but in the long run they are easy to access.
  • Mounting options: Wall Ceiling or floor / table top
