Best 240v Electric Garage Heater [2021 Reviews]

When the temperature drops, it might become difficult to work in your garage. To alleviate the cold weather, what you’ll need is a good heater.

We recommend electric heaters because they’re safer than gas heaters. That’s especially important in a garage containing gasoline, paint, and other highly-flammable substances.

Another benefit of electric heaters is they don’t require you to refill gas bottles every week. Depending on how strong you are, these bottles can get extremely heavy – although, maybe the team here at Garage Spot needs to hit the gym more often. You be the judge.

Most people assume electric heaters are expensive, but that’s not always the case. The great thing about electric heaters is they only heat the room they’re in. If you decide to use standard heating, it would automatically heat the whole house, costing you more in electricity.

That being said, trying to find the best 240v electric garage heater online can be a rather unpleasant experience, especially if you don’t know what you’re looking for. Don’t worry though, our team of experts has put together a list of the top 5 heaters for your garage in 2020.

How to Choose a 240V Electric Garage Heater

How to Choose a 240V Electric Garage Heater

When choosing a heater for your garage, there are certain things you should look for.

  • Mounting – You want to ensure the unit you purchase comes with mounting brackets that can be easily installed on either the wall or ceiling – or both. Luckily, all the heaters listed above come with mounting brackets.
  • Remote Control – If you’re going to mount your heater on the ceiling of your garage, then you’ll need a remote control to adjust the settings. The last thing you’ll want is to have to use a ladder to change the temperature.
  • Overheat Protection – If your heater overheats regularly, you may begin to experience technical issues and could end up with a heater that just doesn’t work. Hence, it’s essential to ensure the heater you purchase comes with an auto-off feature if it becomes too hot.
  • Design – Making sure your heater looks good is also something to keep in mind. However, this is not always necessary if you don’t care how your garage looks – Garages are not usually the most aesthetically pleasing rooms anyway.

Electric Heaters vs. Other Heater Types

Electric Heaters vs. Other Heater Types

Let’s look at some of the most popular heater types available and compare them to an electric heater.

  • Combination Heater – A combination heater is usually attached to the wall in your house. These heaters are great for keeping your home warm in the winter months but cannot generate the power necessary to keep a whole garage warm. Garages are typically colder than standard rooms and require a fan and more power.
  • Infrared Heater – These types of heaters aren’t designed to heat your entire home. They typically focus on keeping areas of a room warm that tend to get cold more often. Therefore, you most commonly find these heaters in large warehouses and airplane hangers with large doors that continually open. These heaters can be used in garages but won’t provide the same level of heat as the electric heaters listed above.
  • Gas Heaters – Gas heaters are an excellent heat source and even work well in garages – They’re also more cost-effective than electric heaters. The negatives of a gas heater are they cannot be mounted to the ceiling or wall. You also have the inconvenience of refilling and changing gas bottles.


How Much Power Do You Need?

It really depends on how big your garage is, what’s stored in it, and also the ambient temperature of the room. Even with all these factors considered, it’s still hard to determine how many watts your heater will need. A good rule of thumb is to stick with 10 watts per square foot of space you’re trying to heat.

Are Garage Heaters Safe?

Safety is a common concern among people who are looking to install a heater in their garage. While there’s always a safety risk, electric heaters are generally considered safe.

However, there are precautions you should take when installing an electric heater in your garage. Specifically, you need to make sure there aren’t any items directly in front of the heater, as this could be a fire hazard.

Another concern is garages contain highly flammable liquids such as gas, which questions the safety of heaters being present. It is something to be especially wary of with gas heaters. Electric heaters, on the other hand, are considered safe to use around these substances.

We also recommend turning your heater off when leaving the room. If you follow these precautions and stick with high-quality heaters, you should be fine.

Where Should I Put My Heater In The Garage?

For a garage, we recommend placing your heater in the coldest corner of the room and direct the heat to the center, ensuring that the whole garage remains heated as opposed to only certain areas.

What Size Electric Heater Do I Need For My Garage?

It depends on how big your garage is. If your garage is small, then a smaller heater will be fine. If your garage is quite large, then you should stick with a bigger heater.

One thing to keep in mind is the smaller the heater, the less power it provides.

Should I heat My Garage In The Winter?

Absolutely. A heated garage will help keep your whole house warm because a lot of cold air escapes from your garage in the winter months, which can affect the temperature of your entire house.

With Winter being so cold, you’re not going to be working outside. The most common alternative is working from your garage – however, most garages can be just as cold! That’s why it’s crucial to have a heat source – Not only will you feel more comfortable, you’ll also work efficiently.

Can I Use Electric Heaters In Other Rooms?

You can, but we don’t recommend using the ones from this list. The heaters on this list are commercial and designed for garages.

If you’re looking to get an electric heater for a different room in your house, we recommend the Trusttech Space Heater. This heater can be adjusted between 50-95° F and heats up in as little as 3 seconds! It also comes with remote control and an ultra-long distance sensor, which is great for adjusting the setting while watching TV.

If that wasn’t enough, this heater also works on a set timer, meaning you can have it turn off after a certain number of hours. It also comes with safety features in places such as tip-over and overheating protection.

In Brief…

Choosing a high-quality electric heater can make all the difference in the Winter. While selecting a heater for your home is a walk in the park, a heater for your garage takes more in-depth research since your garage needs a more powerful heater than other rooms in your home.

If you take away one thing from this article, it’s to ensure that you understand some of the heaters will require basic electrical knowledge to install. You can hire an electrician if you prefer.

You’ll also want to be aware of the power output your heater can provide. The bigger the garage, the higher the wattage required. A more powerful heater will prevent half your garage from being hot while the other half is freezing cold.

All heaters in this article are carefully selected by our team of experts and are of excellent quality. If we had to choose the best heater on this list, we would go for the Fahrenheat Electric Heater.
