Types of Electric Garage Heaters

There are several types of electric garage heaters that you can choose from:

  • Forced air heaters: These heaters use a fan to circulate heat throughout the garage. They are usually powered by electricity and are relatively easy to install.
  • Infrared heaters: These heaters use infrared technology to heat objects and surfaces directly, rather than heating the air. They are ideal for smaller garages or for spot heating specific areas.
  • Ceiling-mounted heaters: These heaters are installed on the ceiling and use convection to circulate heat throughout the garage. They are a good choice for larger garages or for those with high ceilings.
  • Wall-mounted heaters: These heaters are installed on the wall and use convection to circulate heat throughout the garage. They are a good choice for smaller garages or for those with limited floor space.
  • Baseboard heaters: These heaters are installed along the baseboard of the wall and use convection to circulate heat throughout the garage. They are a good choice for smaller garages or for those with limited wall space.

What to Consider When Buying the Best Electric Garage Heater

Before choosing an electric garage heater for your garage or work space, take a few minutes to educate yourself on the most important shopping considerations to keep in mind.

Garage Size

It’s critical to know the size of your garage or work space when selecting an electric garage heater. If you get a unit that is not powerful enough for the space you want to heat, then you will be left working in the cold, and you will be out the money you spent on the wrong heater. A good rule to follow for choosing an adequate garage heater is for every 10 watts of output, you can heat 1 square foot of space. For instance, a 150-square-foot garage or shop will be fully heated by a 1,500-watt electric garage heater.

Also, keep in mind the amount of actual space you use. If you use only a third of your garage while the rest is for your vehicle or for storage, then you may be able to get a smaller heater that will provide enough heat for you but won’t waste energy by heating up the rest of the unoccupied room.

Portable vs. Mounted

Electric garage heaters can be separated into two main installation types: portable and mounted.

  • Portable electric garage heaters can stand on the ground or a table, and you can maneuver them wherever and however you want to get the best heat for the room. These heaters don’t require much installation or setup and generally need only an available outlet to begin working right out of the box. These heaters take up floor and table space, and their cord can be a tripping hazard.
  • Mounted electric garage heaters can be wall-mounted or ceiling-mounted. They can also be hardwired into the building’s electrical system for a more powerful heat output, or they may be plugged into a regular power outlet, which is a style of mounted heater that is easier to install than the hardwired type. Mounted heaters are a great option if you are looking for a semipermanent heater that you will have to set up only once. However, if you don’t have a large garage or workshop, these bigger units may be too powerful for a small space.

Adjustable Thermostat

If you want an electric garage heater that can monitor the ambient temperature of the room and turn on when the temperature is too low and off when the temperature is too high, then you need a heater with a built-in adjustable thermostat. This feature allows you to choose your ideal temperature for the garage, and the heater will automatically begin heating until the ambient air in the room reaches that temperature. It’s an ideal function in colder climates that may need 24-hour heating because the auto-on and auto-off features will keep your garage at the right temperature without wasting unnecessary energy.


Any heating or cooling appliance will require some maintenance to continue working effectively over the years, and an electric garage heater is no different. Lightweight heaters are less expensive than more durable units, but they won’t last as long. If you don’t mind replacing a heater every couple of years, you can get sufficient heat without having to do much maintenance.

More durable electric garage heaters will last longer, but you’ll need to clean them regularly, inspect the power inlets for breaks, and test the heat outputs to ensure they are functioning properly. If you do this on a regular basis, these more expensive heaters may end up costing less over time than having to replace several lightweight heaters.

Safety Features

Electric garage heaters can be dangerous if they are not properly installed, set up, and used. Fortunately, many manufacturers have begun adding safety features designed to make the product as accident-proof as possible, including tip-over mechanisms, overheating protection, and cool-touch features.

  • Tip-over mechanisms were designed because electric garage heaters are easy to knock over, especially when they’re in a busy workshop, small garage, or a home with small kids. This mechanism activates when the heater is knocked over, automatically shutting down the heater to prevent damage.
  • Overheating protection is a useful feature that’s designed for days of prolonged use when the ambient temperature can fluctuate by several degrees, causing the heater to begin to overheat. When this happens, the overheating protection senses the rising temperature and shuts off the heater to prevent external damage to your garage and to stop internal damage to the heater.
  • Cool-touch features are primarily used for wall-mounted and portable garage heaters because they are often set up or installed in locations where passing children or adults can come into contact with the sides of the heater. Heaters without this safety feature can cause a significant burn, but the cool-touch feature allows you to touch or grab the outside shell of the heater without injuring yourself.

Additional Features

Electric garage heaters have advanced with the times and now come with a variety of additional beneficial features. Take a look at these features below to see if any are must-haves for your electric garage heater.

  • Extended cords give you the ability to place the garage heater anywhere within reach of the outlet, expanding the available areas to set up and keep warm.
  • A handle on a portable heater makes it easier to pick up and move around the garage so you can find the best place to put it.
  • Wheels can make portable space heaters easier to move.
  • Louvers on your electric garage heater allow you to direct the flow of the heat with a fan-forced or ceramic garage heater.
  • WiFi-enabled electric garage heaters can connect to a website or an app so you can control the heater through your phone.

The Advantages of Owning an Electric Garage Heater

There are many benefits to owning an electric garage heater, but one of the foremost advantages of these useful appliances is being able to have a warm, comfortable garage work space year-round.

Electric garage heaters versus built-in heating systems also give you the ability to choose how and where to use them, so long as you have an available power source. Install a semipermanent heater on your garage wall or ceiling if you prefer a reliable heat source that you don’t have to set up every time you use it. If you want more maneuverability with your electric garage heater, then you can get a portable product that just needs an outlet and somewhere to stand.

Simple installation and eco-friendly operation are two primary advantages that electric garage heaters have over gas heaters. Electric heaters are also more affordable, and their heat output is optimal for most residential garages, though very large spaces may call for a more powerful heating option, such as a gas heater.

  • Using an electric garage heater allows you to work effectively in your garage in cold temperatures.
  • Electric garage heaters can be mounted on your ceiling or wall in a semipermanent position, or they can be portable, giving you the freedom to choose where and how to use them.
  • For residential garages, an electric heater is an inexpensive, effective option that is easy to install compared to natural gas garage heaters.

How We Tested the Best Electric Garage Heaters 120v

Testing the best electric garage heaters 120v required a few days’ worth of work, as the temperatures in the garage needed to be low enough to give these heaters a fair shake. Over the course of three mornings, the temperatures were in the high 30s or low 40s here, which gave us the perfect opportunity to test them out.

We tested the setup. We attached and hung brackets, wired heaters, and installed apps to see how easy it was to go from in the box to heating the garage. Then, we cranked these heaters up to see how well they’d heat the garage. We also performed a test where we let the heater regulate the temperature in the space by itself (which is why we could only test a few a day).

We tested the best electric garage heaters’ safety functions. While we weren’t able to get any to overheat, we did tip them all over to ensure they worked as they should. If they didn’t (one didn’t), we noted it in the guide.

electric garage heater 120v suitable for crowd

If you’re looking for an electric garage heater that is suitable for a crowd and runs on 120V power, you may want to consider a forced air heater or a ceiling-mounted heater.

A forced air heater is a popular option for heating large spaces, like garages, because they use a fan to circulate heat throughout the space quickly and efficiently. Many models are available that can run on 120V power and are suitable for heating a crowd.

Ceiling-mounted heaters are also suitable for heating a crowd in a garage. These heaters are installed on the ceiling and use convection to circulate heat throughout the space. They are a good choice for larger garages or for those with high ceilings.

When choosing a heater, you should also consider the size of the garage and the amount of heat you need to generate in order to make the space comfortable for a crowd. It’s usually recommended to consult with a professional to check for the most suitable solution for your specific needs and local regulations

Also, it’s important to remember that any electric heater, no matter the size, should be placed in an area where it won’t be a tripping hazard, and that has proper ventilation.


How much power do electric garage heaters use?

The power consumption of an electric garage heater can vary depending on the size and type of the heater. A small portable heater may use as little as 1,500 watts, while a larger industrial heater can use up to 15,000 watts.[1]Electric Garage Heater Power Consumption Calculator

Can electric garage heaters be used in damp or wet conditions?

Many electric garage heaters are not suitable for use in damp or wet conditions. However, there are some models that are specifically designed to be used in damp or wet environments, such as radiant heaters. It is important to consult with the manufacturer or a professional before installing a heater in a damp or wet location.

Can electric garage heaters be used as primary heat source?

It depends on the size and power of the electric garage heater, as well as the size of the garage.

This includes regularly cleaning the heater and its filters, keeping it free of debris, and making sure that the wiring and connections are tight and secure. It’s also important to follow the manufacturer’s recommendations for maintenance and to hire a professional for any repairs or service needs.

Where should I place my garage heater?

You can place portable electric garage heaters anywhere you want. If they aren’t giving you the heat and results you want, just move them. Fixed or mounted electric garage heaters that have a forced-air or ceramic-heating function should be installed in the coldest corner of the garage with the air directed toward the center of the room.

Fixed or mounted electric garage heaters that use infrared or radiant heating need to be positioned at least 24 inches from the walls of the garage to ensure that they do not cause a fire. Measure and mark out this safety zone, then select an area within the zone that is close to your usual work space so you can benefit the most from the heater when it is installed.[3]Places You Can Hang Your Garage Heater

How many watts do I need to heat my garage?

The type of heater, the layout of your garage, the contents of your garage, and the ambient temperature are all factors that can make this a difficult measurement to pinpoint, but a basic rule to follow is approximately 10 watts for every square foot of space that you want to heat.

How much does it cost to run an electric garage heater?

This depends heavily on your local electrical costs, the wattage of the electric heater, and how long the heater has been used. However, on average, a 1,500-watt electric space heater will cost between $0.18 and $0.25 per hour to use.[4]How Much Does a Garage Heater Cost?
