Types of Electric Garage Heaters

Garage heaters use different methods to deliver heat efficiently throughout the space. These heaters also use different power sources, but mainly electricity or gas. Depending on the size and insulation of your garage, and especially, the availability and cost of these resources, one may be more ideal than the alternative. Generally, natural gas heaters or propane garage heaters are best for extremely cold, large spaces. 

If you simply need zone heating in an average one to two-car garage and workshop, then one of the electric garage heaters above may be suitable for you. Most electric garage heaters are simple and standalone, so you don’t need to install additional ducting from your home’s central heating and air conditioning if you have one.

Electric garage heaters typically fall under one of the following types:

Fan-Forced Heater

Fan-forced electric heaters use some kind of heating element inside the unit to rapidly heat the surrounding air. A fan inside the heater pushes the hot air out to warm up the surrounding air within the garage, raising the temperature in the process. 

They don’t require venting but they may suck up moisture and dry up the air. These heaters are best for garages that are insulated because they use a fan to spread the heated air and are able to heat an enclosed space quickly. They also work well to add heat instantly and move hot air across larger distances. Although, as these heaters need a fan for heating, they are usually on the noisier side and may draw more energy when running. They can be portable or mounted on a wall or ceiling for permanent installation.

Infrared Heater

Infrared garage heaters are sometimes also called quartz heaters or radiant heaters. They generate radiant heat that works just like the sun heats up the Earth. They do not warm up the air, but rather emit waves that transfer heat to physical objects around it. This means the air temperature will not change drastically, but you will feel warm in your garage or workshop with the heater close by. 

Because of this, infrared heaters are typically used in smaller garages or other residential spaces. Some homeowners may also use multiple units in one room. Depending on the size of the garage and the number of items inside, infrared heating may help retain heat longer.

Ceramic Heater

Ceramic electric garage heaters also use a heating element like fan-forced heaters. However, the difference is that the element heats up ceramic plates instead of directly distributing the heated  air to the room. In some models, the ceramic plate radiates heat into the room. In the case of convection ceramic heaters, they utilize a fan for quicker heat distribution. This type of heater is best suited for small garages or for personal use in tight spaces. 

How to Choose the Best Electric Garage Heater

Before you choose an electric heater for your garage or workshop space, the following factors are some important considerations to bear in mind.

Garage Size

The size of your garage or workshop is a critical factor to consider when choosing a heater. If you get an undersized heater for your garage, then it may not be effective at all and you’ll end up wasting a lot of money buying and running the heater. 

The heat output of a heater determines the amount of space it can efficiently cover. For electric heaters, this is often measured in Watts, which also refers to the total power consumption per hour. As a rule of thumb, 10 watts of output can heat one square foot of space. So as an example, a 150-square-foot area can usually be warmed by a 1,500-watt electric garage heater. However, there are other factors that can affect how much space your heater can effectively cover. 

A tightly insulated garage keeps the cold air out and helps the heater work more efficiently. Electric heaters with fans are great in this case because they can disperse the heated air evenly. Meanwhile, radiant heaters are ideal for basements with poor insulation because they heat up the objects around them instead of the air.

Also, keep in mind the total amount of space you actually use. If you only use a portion of your garage while part of the space is used for storage or vehicles, then a smaller heater may be good enough for the area where you’ll actually spend time. You can get a portable heater that will provide the heat you need but won’t waste energy heating up the unoccupied space in your garage.

Portable vs. Mounted

Portable vs. Mounted Garage Heater

Electric garage heaters can be further classified into two types depending on the installation: portable and mounted.

Portable electric garage heaters can stand alone on the ground or on a table. You can easily move them and place them anywhere you want to get the best heat you need for the space. These heaters do not involve a lot of complicated steps for installation and setup. They generally only require a compatible power outlet to start working right out of the box. However, these portable heaters do take up more floor and table space and the power cords can be a tripping hazard, so you need to keep a distance from them when working.

On the other hand, mounted electric garage heaters can be installed on the wall or ceiling with included hardware and tools. They can also be hardwired into your home’s electrical system for more powerful heat output, or they may be plugged into a standard power outlet for easier installation. Mounted electric heaters are your best option for a semi-permanent heating solution in a large garage or workshop space. However, if you don’t have a large space, these bigger units may be too powerful and consume too much electricity.

Adjustable Thermostat

Adjustable Thermostat

Electric heaters offer more precise control over the unit’s operation to make it more effective and efficient according to your needs. If you want a heater that can monitor the ambient temperature of your garage and turn on automatically when the temperature drops and turn off when the temperature is too high, then look for an electric garage heater with a built-in adjustable thermostat. This feature allows you to set your preferred temperature for the garage (or select a pre-set condition) and the heater will automatically begin heating until the ambient temperature reaches your setting. This is an extremely beneficial function during colder seasons when you may need 24/7 heating in your garage. The automatic on and off features will keep your garage at your preferred temperature at all times without wasting energy. Most electric heaters come with a remote control that allows you to do all the changes from anywhere in the room. This is especially useful for ceiling-mounted units.

Maintenance

Almost any appliance will require some maintenance from time to time to keep it functioning properly over the years. Your electric garage heater is no different. While portable heaters are less expensive than larger, more durable units, they aren’t built to last as long. If you don’t mind replacing a heater every couple of years, then these heaters may be good enough for you without a lot of maintenance requirements.

Heavy-duty electric garage heaters are built to last longer in larger spaces with harsher conditions, but they require more meticulous maintenance. You’ll need to clean them regularly, inspect the power inlets, and check each component to ensure they are functioning properly. While it may seem like a lot of effort and time, regular proper maintenance can help these more expensive heaters work for longer and cost you less in the long run.

Safety Features

Like any heating or cooling appliance, electric garage heaters can be dangerous if they are not properly installed, set up, and used.  To ensure the safety of electric heaters, look for certifications from recognized organizations that test them. If the heater has been tested and approved, there will be a label on the unit. Look for this label to make sure the unit has passed safety standards. Also, look for the following safety features:

Overheating protection is a useful feature when you need to use the heater for long periods. The ambient temperature in your garage can fluctuate by several degrees throughout the day, which can cause the heater to overheat when left to operate. The overheating protection monitors temperature and automatically shuts off the heater to prevent any damage to your heater’s components or accidents in your garage.

Tip-over protection must be included in electric garage heaters because they are easy to knock over, especially portable units placed in a busy workshop or a small garage. This feature automatically activates when the heater is knocked over, shutting down the unit to prevent damage or accidents.

Cool-touch housing is especially needed for wall-mounted and portable garage heaters. While the internal components heat up, the exterior can also get too hot to touch, which can be dangerous in the case of heaters installed in locations where you can come into contact with the heater. Without this safety feature, the sides of the heater can cause burns when you accidentally touch them. 

The Advantages of Owning an Electric Garage Heater

Space heaters are beneficial for many homes. It can also be useful in less-used spaces like the garage. The most important advantage of using an electric garage heater is providing a warm and comfortable garage and workspace year-round.

Compared to central heating, electric garage heaters give you the ability to choose how and where to use them, providing the right power source. You can install a heater on your garage wall or ceiling if you don’t want to have to set it up every time you need it. If you want more flexibility, then you can get a portable unit that you can take anywhere and simply plug in.

Electric garage heaters also offer simple installation and environmentally-friendly operation as advantages over gas heaters. Electric heaters are typically more affordable, providing just the right level of heat output for most residential spaces. Although, keep in mind that extra large rooms may require a more powerful heating solution you can only get from a gas heater.

Using an electric garage heater allows you to control the temperature so you can work effectively in your garage in cold weather. Electric garage heaters can be mounted on your ceiling or wall, or they can be portable. Wherever you choose to place them, these heaters give you the freedom to adjust the settings according to your needs. Lastly, an electric heater is inexpensive and easy to use and install compared to gas heaters.

Space Heater Safety Tips

While space heaters are incredibly useful in cold garages, they pose some safety risks if not used properly. The following are some tips to prevent your heater from turning into a hazard.

Firstly, make sure to use the right size and type of space heater for your garage or workshop space. To ensure safe and efficient usage, always check all its safety certifications and built-in features. These heaters don’t require ventilation and may even work more efficiently with more insulation to enclose the garage tightly and prevent cold air from seeping inside.

Once you get the right type and size of the heater, find a good location for the heater before installing and operating. If you have a small garage, then a portable unit may be enough. If you have a large space but don’t want to sacrifice any floor or table space for a bigger unit, then opt for a mounted installation. Place it on a hard and flat surface and keep it away from other items that may cause it to overheat and flammable materials that can start fires. For units with fans, maintain a distance from your workspace so the warm air does not blow directly on you.

When running the heater, occasionally check if it’s working normally to prevent any problems and find solutions right away. Do not touch the unit itself while running or immediately after turning it off. If you notice anything unusual, turn it off and have the unit checked by a professional.
