Types of Garage Heaters

The first thing every user needs to know is the types of garage heaters that are available in the market. Each of these garage heaters has its own set of advantages and disadvantages and make the choice as to which model you pick is purely based on personal preferences. To ensure that you can pick out the perfect and best garage heater for your home, the following are the most common types of garage heaters:

Fan Forced Garage Heaters:

The fan-forced garage heaters to have an integrated fan to maintain temperature. They are easy to install and hence seem to be the most popular type of garage heaters. It has a very simple mechanism: Electric energy is converted into heat energy. A fan throws out the cold air from inside the garage and blows in warm air heated by the heating elements. These garage heaters can generate a large amount of heat and work quickly.

Infrared or Radiant Garage Heaters:

The infrared or the radiant style garage heaters offer heat via convection, that is, direct heat falls on the items closer to the heater. The mechanism of heat delivery is quite similar to the heat received by the earth from the sun. Thus, compared to fan-forced garage heaters, infrared heaters tend to offer a more comfortable kind of heat. However, at the same time, it is imperative to stand in close vicinity of this heater to fully enjoy the benefits of the garage heater. Hence, they are perfect only for smaller garages since they heat objects rather than heating the air around your garage.

Fuel-based Garage Heaters:

The fuel for powering fuel-based garage heaters could be anything: Diesel, Natural Gas, or Kerosene. Since they do not need an electric supply, they are extremely portable and can easily heat up any garage quickly and easily. They are ideal for large garages as long as proper ventilation is available for the exhaust. Using them in enclosed spaces is can result in a safety hazard.

Power Needed by Electric Garage Heaters

Every garage heater carries a power rating in British Thermal Units (BTU). Thus, you can judge the heating capacity of an electric garage heater by checking the wattage and the BTU of the heater. However, do bear in mind that this rating is the measured output under ideal and controlled environments. Hence, you must purchase a heater having a greater capacity than your requirements as it will make up for any poor insulation or draughts.

Safety Features of Electric Garage Heaters

When a user purchases an item, their primary concern is safety and security. To ensure that you can continue working in your garage without having to worry about the heater, some of them carry safety features to ensure seamless operation without any mishaps. The following are a few safety features of electric garage heaters that you should look for while making your purchase:

Tip-Over Switch:

Accidents can happen at any time. It is very much possible that while working, something may topple over or knocked down while you may be busy tinkering. In some cases, it could be your heater itself! Thus, a tip-over switch is an essential feature that shuts off your garage heater if your heater is accidentally knocked over, thereby preventing a major mishap.

Overheat Protection:

Since heaters operate for long durations, it may be possible that the heater could get overheated. The overheat protection feature ensures that your heater turns off when it reaches really high temperatures so as to avoid any fire hazard or damage to the internal machinery of the heater.

Cool Touch:

Since the primary purpose of a heater is to blow out hot air, the heater and its surroundings such as the floor or the table would also get hot. Quite similarly, even the exterior surface and the body of the garage heater can get too hot to touch. Imagine what would happen if an unsuspecting pet or child (or even adult) would touch such a surface. This situation can really get serious. Hence, for security reasons, a cool touch heater would be ideal.

Adjustable Louvers:

Louvers allow you to control the direction of the warm air. If you get a garage heater with adjustable louvers, you can control in what direction the air should be flowing. Thus, you will not have to keep adjusting the position of the heater and simply fiddle the knobs of the louver to get you sung, warm air in whichever direction.

Length of Power Cord:

The length of the power cord is an important item that you should consider while choosing the best electric garage heaters. A long power cord ensures that you can make your heater portable without having to unplug your appliance and look for new and closer power outlets. While using extension leads may seem like an alluring option, but given that electric heaters are high power devices, it could be an electrical hazard. Therefore, pick a garage heater that has a long enough power cord for you to place the electric heater around your garage comfortably.

Carry Handle:

A carry handle is indispensable when you wish to carry around your heater comfortably. It makes your appliance all the more portable. With a carry handle, you can easily lift your garage heater and place it elsewhere without any issue. While a carry handle may not be a mandatory inclusion, it definitely is a convenient addition.


Once again, wheels enhance the portability of your garage heater. You can easily move around the heater with the help of wheels and it will not require any lifting. Since garage heaters are bulkier and heavier than other heaters (due to the large size of their heating element), lifting and carrying such heaters can put a strain on your back. Thus, a garage heater with a caster or wheels will be extremely convenient.

Tips to Keep Your Garage Warm and Safe

Whether you use your garage as a workshop or an exercise room, keeping it warm and toasty is necessary to stay comfortable in the place even during the cold winters. Following are some tips that you can follow that will boost the efficiency of your electric garage heater and keep your garage warmer for longer durations (while remaining safe):

  • If you are confused about choosing between a fixed and a portable garage heater, opt for a fixed heater since portable garage heaters make use of flammable substances as fuel.
  • If you do happen to pick a portable model due to some reason or personal preference, ensure that it is not placed near items such as gasoline or spray paints, which are a fire hazard since garage heaters can get very hot.
  • For maximum safety, select a garage heater that has electric radiant ceiling panels, is vent-free, and operates on sealed combustion.
  • Position your heater in a way so that it does not directly blow hot air on your workstation or the floor region that you would be using.
  • Avoid using a freestanding garage heater as it has a higher chance of being knocked over, especially when it is kept on surfaces such as tabletops.
  • Point the heater towards the middle of the garage so that the heat dissipates evenly throughout the garage. Through this technique, you can make the most of your garage heater.
  • You can use radiant panels to absorb and reflect the heat so as to keep your garage warmer for longer durations. However, since they take a while to be effective, patience is advised in their case.
  • Insulate your garage so that no heat escapes from there. Insulation also ensures that there is no draught blowing into the garage from external openings.
  • While insulating your garage, it is necessary to ensure that the doors and windows are properly insulated. At the same time, even the ceiling should bear insulation to trap in the heat.
  • If there are cracks and openings in your garage, seal it with caulk or a similar sealant to fill these gaps. This will prevent any droughts.
  • Choose an effective garage heater that compliments the size of your garage. Also, factor in the time that will be taken by the heater to raise the temperature of your garage.
  • Check if your garage heater needs any ventilation and install it accordingly. Create a thorough installation plan and hire a professional, if required.
