Top 10 Best Electric Garage Heaters

6 Best Electric Garage Heaters

1. Heat Storm HS-1500 Wi-Fi Infrared – Best Electric Garage Heater Overall

Heat Storm HS-1500 Wi-Fi Infrared Heater

On the first place on the list is a great electric garage heater from Heat Storm made for both small and larger garages. While smaller space heaters might get the job done in smaller garages if you’re looking to heat up a larger garage, then you’re going to need something with a little more oomph. That’s where the Heat Storm HS-1500 Wi-Fi Infrared Heater really shines.

This space heater provides plenty of power to heat up your garage, and it’s one of the easiest electric space heaters to use. Not only does it have knobs right on the space heater, but it also uses Wi-Fi capabilities so you can change the settings with the click of a button on your phone.

This particular model mounts up to a wall to stay out of your way, but there is an option with feet if you don’t have the wall space. The entire space heater is extremely energy efficient, which means you won’t send your energy bills through the roof when you’re using this heater.

Finally, while this space heater is more expensive than some of the smaller space heaters on our list, compared to other large space heaters, it’s super affordable. In fact, our only complaint about this space heater is the fact that you can’t get both the feet and the wall-mounting capabilities in one unit.

That means if your needs change down the road, you’re stuck with one or the other. It’s not a huge deal for most people, but we would love the extra versatility if they included both capabilities on each model.


  • Affordably priced for a larger heater
  • Wi-Fi capabilities
  • Easy to use
  • It stays out of the way
  • Energy-efficient design


  • You need to have wall space to use it

2. ISILER Space Heater – Best Budget

ISILER Space Heater

If you’re on a tight budget but simply need an electric space heater for your garage, check out this ISILER space heater. Not only is it super affordable, but it quickly warms up rooms and it’s super easy to set up and use.

It features both tip-over and overheat protection to help keep you safe, and it’s one of the easiest space heaters to move around. You get to control the temperature with an adjustable thermostat, which gives you more control than ever.

However, it is a budget heater and nothing highlights this quite like the fact that it really only works well in smaller spaces. The ideal maximum square footage for this space heater is just 108 square feet, which is a bit smaller than most garages.

However, because of how lightweight and portable this space heater is, it’s pretty easy to move it to wherever you’re working in the garage that day. If you don’t need to heat up the entire garage, this space heater can be the perfect fit.

Even better, since you’re not heating up the portion of the room you don’t need, you’re saving yourself a bit of money both in the initial price of the space heater and the electrical cost associated with running it!


  • Very affordable
  • Tip-over and overheat protection
  • Warms up rooms quickly
  • Easy to set up and use
  • Adjustable thermostat control


  • Smaller heater only works for small spaces

3. Broan-NuTone High-Capacity Wall Heater – Premium Choice

Broan-NuTone High-Capacity Wall Heater

If you want the best of the best for your garage, then you really need to check out the Broan-NuTone High-Capacity Wall Heater. It’s a 4,000-wattage space heater that can easily heat up your entire garage.

However, keep in mind that to achieve this maximum wattage you’ll need to use 240-voltage to install it, and that’s not something that every garage has access to. Sure, you can convert it to a 120-voltage, but you’re cutting the maximum wattage in half to 2,000.

That makes the installation process a bit more complicated unless your garage already has those outlets installed. Second, one of the major selling points of this space heater is that it has a natural-looking appearance if you recess it into the wall.

While that’s true, not every garage comes with a setup that’s easy to install a recessed space heater into. You don’t have to recess this heater, but it won’t blend in and look as stylish if you don’t. Still, this is our premium choice, and that’s because it does a lot of things right.

If you take the time to install it properly you get a top-notch space heater with an appearance that other options can only dream of. It runs quietly, and it’ll easily last year after year thanks to its super-durable construction.

It comes with built-in thermal overload protection to keep you and everyone else safe, and it’s also one of the easiest space heaters to use once you finish setting everything up. If you’re looking for the best of the best and don’t care about the more complicated install, this is it and it’s not all that close.


  • Very effective and discreet heater
  • Very easy to use
  • Thermal overload protection built-in
  • Very durable design
  • Quiet design


  • More expensive option
  • Works best with 240-voltage
  • Hard to recess the heater – depending on your garage setup

4. AgiiMan Portable Electric Garage Heater – Best For Small Garages

AgiiMan Portable Electric Garage Heater

Not everyone has a massive garage at home to heat up, and if that’s you, then you don’t need to invest in a larger and more expensive space heater. The AgiiMan Portable Electric Garage Heater is exactly what you need.

It’s powerful enough to heat up a smaller garage with ease, but it’s more affordably priced, so you’re not overspending on features that you don’t need. Another huge perk for you is that it uses an energy-efficient design, and this will keep your electric bills lower than if you used another type of space heater.

While it’s an affordable small space heater, you still get some of the top technologies out there too. You still get the overheat protection to keep you and your family safe, and it uses a built-in thermostat to keep your garage at the perfect temperature.

It’s everything that you could ask for in a space heater at a price that you could only dream of if you needed a larger space heater. If you have a small garage don’t overpay. You can set this space heater up in seconds, and it’ll do everything you want and more.


  • Affordably priced
  • Easy to set up and move
  • Built-in overheat protection
  • Thermostat controlled temperature
  • Energy-efficient design


  • It only works well in smaller spaces

5. Comfort Zone Ceiling Mounted

Comfort Zone Ceiling Mounted Radiant Quartz Heater

If you’re looking for a really good combination of price and performance, then the Comfort Zone Ceiling Mounted Radiant Quartz Heater is the way to go. Not only is it one of the easiest options to install and use, but it does a great job of keeping you warm while you’re working in your garage.

This heater includes an overheating safety sensor to help keep you safe, and even better, it comes with two units! That means you can set up multiple stations to help keep you warm in your garage.

The only real drawback to this electric garage heater is that it only heats things up in its direct path. That means if you’re looking for a garage heater to heat up your entire garage, this probably isn’t what you’re looking for.

But if you’re looking for something to keep you warm out in your garage while you’re working, you won’t find a better choice. The distinction is important, but it does allow this space heater to be available for a lower price, and it’s a more energy-efficient design.


  • A great mix of price and performance
  • Easy to install and use
  • Includes an overheating safety sensor
  • Includes two units
  • Very effective heater


  • Only heats things up in its direct path

6. Briza Infrared Garage Heater – Best Portable Garage Heater

Briza Infrared Garage Heater

If you’re constantly moving around your garage or simply want to have a space heater you can move out to different events, then the Briza Infrared Garage Heater is the way to go. Sure, it’s one of the more expensive options on our list, but considering how easy it is to use and how effective it is, it’s worth every penny.

In fact, this infrared garage heater comes with both wall mounting capabilities and a tripod, which makes it one of the most versatile options on our list. Furthermore, tons of safety features make it one of the safest heaters to use.

Those features include a tip-over protection sensor, an overheat sensor and a built-in timer that ensures you never forget to turn it off. But while it’s a more expensive choice, that’s not our only complaint. We also wish that it controlled the temperature output via a thermostat.

Instead, this electric garage heater simply has three heat levels you can cycle through. While that gives you some versatility and control, it’s not as precise as some of the other garage heaters we highlighted. It’s not a huge deal, but for the price of this heater, it’s something we think it should have.


  • Very easy to use and move
  • Super effective heater
  • You can wall mount if you want
  • Remote control activated
  • Built-in timer
  • Tip-over protection features


  • More expensive option
  • Not controlled by a thermostat (only three heat levels)

7. Dr. Infrared Portable Space Heater

Dr. Infrared Portable Space Heater

If you really dig the appearance of classic hardware and appliances, then you’re going to love the Dr. Infrared Portable Space Heater. It definitely has an old-school appearance that isn’t for everyone, but for others, it matches the décor perfectly.

But while it might have an old-school appearance, it still has all the latest safety features. That includes tip-over protection, overheat protection, and a 12-hour shutoff timer. These features help reduce the risk of an accident, which is a pretty big deal.

This corded electric space heater is also super simple to set up, as it uses standard 120-voltage that you plug into just about any wall outlet. But while there’s plenty to love about this space heater, it didn’t earn one of the top accolades for a reason.

First, it’s a bit more expensive compared to some of the other space heaters on our list. Second, it’s larger than many of the other space heaters. That means it takes up more space, and if you don’t like the classic appearance then there’s nowhere you can really hide it.

But take a look at it, if you like the way it looks and don’t mind spending just a little bit more, it might be the perfect electric space heater for your garage.


  • Energy-efficient design
  • Tip-over and overheat protection
  • 12-hour automatic shutoff timer
  • 120-voltage


  • Slightly more expensive
  • Bulkier setup

8. DIMPLEX Garage and Shop Heater

DIMPLEX Garage and Shop Heater

There are few space heaters that are going to give you as much power as the DIMPLEX Garage and Shop Heater, which is a pretty big deal if you live in a colder climate and have a larger garage. However, while we love the heating capabilities, it’s also a more expensive option, and it needs 240-voltage.

That makes it much more challenging to set up if you don’t already have a 240-voltage outlet in your garage. It’s this and the price that sent it down our list. Still, if you do have those capabilities and you can afford the upfront cost, you’re really getting an outstanding electric space heater.

It’s super easy to use once it’s set up, and its hanging design saves a ton of space in your garage. Furthermore, it has a super durable construction that ensures you can use it year after year with ease.

Once you add in the overheat protection features, you get an outstanding space heater that can transform your garage from an icy retreat to a tropical feeling paradise. It’s all about whether or not you have the capabilities to set it up and can afford it.


  • Very effective heater
  • It has overheat protection
  • Very durable and long-lasting design
  • Easy to use and saves garage space


  • More expensive option
  • Needs 240-voltage

9. Amazon Basics Oscillating Ceramic Heater

Amazon Basics Oscillating Ceramic Heater

The Amazon Basics Oscillating Ceramic Heater is the lowest-priced option on our list, and while it doesn’t quite earn the nod as our budget choice, it’s still a nice little low-priced space heater.

Not only is it super affordable, but it’s also the easiest space heater on our list to set up and use. Because of its smaller size, it fits perfectly on top of a desk or workbench, which means if you’re stationary when you’re working in your garage, it won’t have any problem heating you up.

Meanwhile, if you do move around some the oscillating function will help you feel some of the heat intermittently as it tries to heat up the entire room. But the real issue with this space heater stems from just that – it’ll try to heat up the entire room.

It’s not the most effective space heater, and it only has three output settings. It produces heat, but not enough of it to heat up a garage all on its own. Still, it does come with a 1-year warranty, and they didn’t sacrifice on safety at all.

It has both tip-over and overheat protection features, which is pretty nice for such a low-priced space heater. It’s not the best of the best, but if you’re on a super tight budget or simply need a small space heater, you could do worse than the Amazon Basics Oscillating Ceramic Heater. Heck, at this price you can get a few of them if you have the open outlets!


  • Very affordable
  • Oscillating design
  • Includes a 1-year warranty
  • Easy to move and use
  • Tip-over and overheat protection


  • Not the most effective heater
  • Only three output settings

10. Aikoper Ceramic Tower Heater

Aikoper Ceramic Tower Heater

The Aikoper Ceramic Tower Heater might be the last option on our list, but that doesn’t mean it’s not a great choice. It uses an energy-efficient design to help keep your energy bill low, and it’s both easy to use and move around.

Not only can you control it from the machine itself, but it comes with a remote control that lets you control what’s going on from anywhere in your garage. And while it’s an affordably priced option, it still has essential safety features like tip-over and overheating protection.

But while we’d be more than happy with this space heater in our garage, it did fall to the bottom of our list for a reason. First, it’s not the most effective design. The tower captures a lot of the heat and doesn’t do the best job dispersing it around the room.

Second, while there are only two output settings for you to choose from. We wish that you had a bit more control over how much heat you can push out, and we wish that it took up a little less space.


  • Energy-efficient design
  • Tip-over and overheating protection
  • Affordably priced
  • Includes a remote control
  • Easy to use and move


  • Not the most effective design
  • Only two output settings

Garage Heater Buyer’s Guide

With so many outstanding space heaters out there, it can be a bit of a challenge trying to narrow it down to just one. We completely understand that, and we understand that you might have a few questions you need to answer before you can pick one.

That’s why we came up with this comprehensive buyer’s guide to walk you through everything you need to know and help you pick out the perfect space heater for your garage the first time.

How Powerful of a Space Heater Do You Need?

You don’t want a space heater that pushes out too little heat to make a difference, but you also don’t want to spend more than you need to on a space heater that’s too powerful for your garage.

As a general rule of thumb, you need about ten watts of output you can heat about 1-square foot. So, for a 1,500-watt space heater, you can heat up about 150 square feet. Meanwhile, a 4,000-watt space heater can effectively heat a 400 square foot garage.

However, keep in mind that this is just a general rule of thumb, and the colder the climate the more powerful space heater you’ll need. For super cold climates you need a more powerful space heater, but the 10-watt to 1-square foot rule is fine for most environments.

Voltage Requirements

Before you bring any electric space heater into your home, it’s essential that you take a look at the wattage that it uses. While the most powerful space heaters out there use 240-voltage, not every garage has 240-voltage in it. In fact, most don’t.

That means if you want a 240-voltage space heater in the garage, you’ll need to retrofit the garage to have a 240-voltage outlet. This can be a more expensive process, although it’ll give the capabilities to have a more powerful electric space heater out there.

The other option you have is a 120-voltage space heater. These space heaters use a standard American wall outlet, making them by far the easiest to use. The tradeoff with this lower voltage is typically the power though.

Most 120-voltage space heaters only power between 1,500 and 2,000-watt heaters. It’s enough for most garages, but using the lower voltage certainly limits your maximum power output some. Finally, keep in mind that some 240-volt space heaters let you convert them to 120-volt, but it typically cuts the wattage output in half.

Advantages of an Electric Space Heater

If you’re considering an electric space heater for your garage, it’s probably because they come with a litany of advantages compared to other heating options. We’ll highlight a few of these perks for you here.

First, compared to a traditional HVAC unit space heaters are very cost-effective. Second, electric space heaters are among the simplest options to install. For most electric space heaters, all you need to do is plug them into an open outlet to get them working!

They also tend to heat up very quickly, so they can start working on heating up your garage faster. Since you don’t want to leave the space heater on all the time, having it quickly heat up your working space is a huge advantage.

Finally, most electric space heaters are both small and super portable. Even if they’re on the larger side of things for an electric space heater, that’s still normally far smaller than other heating options. And since all you need to do is plug them in to get them to work, they’re also pretty easy to move around.

Most electric space heaters are light too, so portability is almost never a concern!

Built-In Protective Features

With any space heater you go with, you want to ensure that it has some minimum safety features. Every space heater should have overheat protection, and every heater on our list has it. This feature cuts the power if it gets too hot, and it’s a great way to prevent a fire.

The next feature your space heater should have is tip-over protection. Not every space heater on our list has this feature, but not every space heater can fall over. If it’s a freestanding electric space heater it needs this feature to keep you safe.

Finally, it’s best if your space heater has an automatic shutoff timer. If you forget to turn off your space heater, this ensures that it doesn’t run continuously. Not only does this reduce the risk of a fire, but it also will help keep your energy bills low.

Different Types of Electric Space Heaters

When you’re picking out your next electric space heater, one of the most important decisions you need to make is the type of electric space heater you will go with. We’ve highlighted four of the options you have and the pros and cons of each here.

Keep in mind that with many space heaters they can consist of more than one style, or they can convert from one style to another!


While hanging space heaters aren’t the easiest to set up, they have a few distinct advantages over every other type. The first advantage is the amount of space that they take up. Since they hang from the ceiling, they typically don’t take up any extra space.

Second, it gives you a little more versatility on where you mount it. Most of the time the ceiling space in your garage is already empty, which gives you more options. Just keep in mind that you’ll still need access to an outlet, even if you do mount them to the ceiling.


Wall-mounted space heaters are typically a bit larger than other space heater options, and as such they often have more wattage and power. They can heat up larger spaces because of this, and they’re an excellent choice for larger garages.

However, you need to ensure that you have an area along the wall that’s open for the space heater and that it has enough space to project heat across the rest of the garage. Mounting these space heaters is a bit more challenging compared to other options, but once they’re up, they’re pretty easy to use and work with.

Finally, wall-mounted space heaters take up a bit more space compared to other electric garage heaters. Double-check that you have somewhere to place the new heater before ordering it.


Portable space heaters come in a wide array of shapes and sizes, but they all have one thing in common, they’re pretty easy to move around. Sometimes these smaller portable heaters can fit on top of tables, other times, they sit on top of much larger tripods.

One of the most notable advantages of portable space heaters is that you can easily move them to exactly where you need them. So, even if you get a portable space heater that isn’t quite powerful enough to heat up your entire garage, you can move it to where you’re working in the garage that day.

Furthermore, if you’re heading out somewhere and need a little extra heat, portable space heaters are typically easy to pack up so you can bring it along. As long as you have somewhere to plug in your portable space heater, you’re good to go.


Tower space heaters are exactly what they sound like, a space heater that stands up in a narrow tower design. These towers often oscillate, allowing them to heat up a wider space.

Tower space heaters require somewhere to stand, but if you have a corner where they can stand, then they’re not a bad choice. Just keep in mind that many tower space heaters don’t do the best job projecting heat out across an entire room – even when they use a higher wattage.

The last thing you want to deal with is a cold garage when you’re trying to get something done. With any of these electric space heaters you can start warming up your garage and turn it into a more usable space.

So, what are you waiting for? Pick out the perfect space heater off our list, and you can turn your frigid garage into a much warmer abode in no time!
