There are generally 5 different types of electric heater to choose from:

Electric Infrared Heaters

Infrared heaters are a popular choice for garages. Even after you’ve turned the heater off, the garage will remain heated for some time. For those concerned about energy efficiency, infrared heaters are one of the most efficient types available today. This type of heater is also known as a radiative space heater and heats people and objects in front of the unit.

Electric Fan Heaters

For those concerned about affordability and performance, electric fan heaters offer a great solution. Also known as blow heaters, these heaters use a fan to move air across the heating element. Generally, fan heaters are energy efficient. However, more noise will be generated by fan-based heaters. If you’re using power tools in your garage, this may not bother you!

Electric Ceramic Heaters

Ceramic heaters are another type of electric heater. With a heating element made from ceramic material, these heaters are safer than other types. You’ll be able to find ceramic heaters that utilize fans or infrared technology, as discussed above. Ceramic heaters are popular due to their fast heat-up times. This type of heater will often remain cool on the outside.

Electric Smart Heaters

Like ceramic heaters, smart heaters will utilize either fan or infrared technology. However, the distinction lies in the added smart functionality. With smart heaters, your electric heater will be able to connect to your home’s Wi-Fi. Of course, this will allow you to control the heater from your smartphone, which adds a new level of convenience to classic electric heaters.

Electric Under-Floor Heaters

Electric under-floor heaters are the most expensive type available today. This type of heater utilizes power lines to heat the floor of a room. However, this requires a complex and costly installation process. While these under-floor heaters can provide efficient performance, the complex installation makes this heater hard to implement in garages.

Here’s a quick summary table of the different types along with their main features:

Factors To Consider When Choosing A 120v Electric Garage Heater

In this section, we’re going to break down the factors you need to consider when purchasing an electric garage heater. By keeping these aspects in mind when shopping, you can ensure that you choose the best electric heater for your garage!

Which Electric Heater Type is Best for You?

There are many different types of electric heater available today.

There are many types of electric heaters available today, many of which are outlined above. This should be a primary consideration when shopping for a heater, as you’ll be able to narrow down your selection by type. For instance, if you want to avoid having a noisy heater, you should rather browse heaters with infrared technology.

Use the summary table above to help you choose which type of electric heater is best for you.

Where Do You Want to Place your Electric Heater?

When shopping for an electric garage heater, you need to consider where you want to place the heater. To save space, you might prefer a heater that is wall- or ceiling-mounted.

However, if you’re looking for a portable electric heater, you might prefer a tabletop model that can stand on your workbench.

Essentially, you need to consider whether you prefer a mounted or portable electric heater:

  • With a mounted heater, you will not be able to move it around.
  • While a portable heater that stands on the floor or table can be moved around, but it will take up more space than a mounted heater.

What Size Electric Heater is Best for You?

Size is another crucial factor. As we mentioned above, portable/standing electric heaters will take up more space than wall-mounted heaters. However, you’ll be able to find portable and mounted heaters of varying sizes. This will also correlate to the heating range, which we’ll discuss in a moment.

Depending on the size of your garage, you need to choose a heater that is appropriately sized. If you opt for a mounted heater, you need to ensure you have sufficient wall or ceiling space available to mount it. If you’re opting for a portable heater, you want to ensure you have enough space for it to stand.

The size of your heater is also linked to energy efficiency, which we’ll discuss next. By choosing a large heater for a small garage, you will be wasting energy. A small heater in a large garage will result in insufficient heat generation. Ultimately, the size of your heater needs to be proportional to the size of your garage.

Is Efficiency Important to You?

With electric heaters, energy efficiency is a crucial consideration! When shopping for heaters, you can use customer feedback to ensure the product meets their indicated heat output claims. As we mentioned above, the efficiency of a heater will be optimized when the heater’s size is proportional to that of the room.

But it’s also always a good choice to go with one that is designed to work efficiently too.

Which Features are Important to You?

If you’re looking for the best value heater, you may be limited in terms of available features. However, there are many features you may want in a heater.

For instance, oscillating heaters can distribute heat more evenly. You may want a heater with an adjustable thermostat. Many heaters will also have numerous heating modes, including Eco modes. When browsing heaters, it’s important to consider which features are offered, and decide how important each feature is to you.

What Range Does you Electric Heater Need to Cover?

When shopping for electric heaters, you need to consider the range of the heater. With fixed or mounted electric heaters, you may find the heat is more direct and has less range. And with portable ones, you are able to move it around to direct the heat where you want it.

Many heaters will specify their range. By comparing this range to the size of your garage, you can ensure the heater is able to properly warm up your garage.

Consider Electric Heater Safety

Finally, you need to consider the safety of a heater. For instance, does the portable heater have a tip-over switch? Many heaters also do not heat up on the outside, which can be an important safety feature for those with children and pets.

As we discussed earlier, the safety of a heater is also linked to the type of heater you choose. Some types, like ceramic heaters, are safer to use.

With all this to bear in mind, here are 6 of the Best Electric Heaters that we believe are available on the market today, depending on what you’re looking for. We’ve also listed out their individual features, along with their pros and cons…
