9 Best Electric Garage Heaters 240v

A 240v garage heater is going to be great for larger spaces.

The best 240v electric garage heater I could find was the Fahrenheat FUH Electric Heater. It’s capable of heating a 400-square-foot garage and can even be used outdoors.

If you’re on a budget, you can go for the Comfort Zone 5000W. It’ll save you cash while still outputting tons of heat (and comes with all the safety features you’d expect).

Below you’ll find all the reviews and even some alternative options.

Best Electric Garage Heater 240v

Fahrenheat Electric Heater for Garage

Key Features:

  • Adjustable louvers
  • Heats up to 400 square feet
  • Built-in thermostat 

This electric garage heater can heat up to a 400-square-foot garage, making it perfect for most standard 2-car garages.

The better insulated your garage is, the more capable this heater will become.

The adjustable thermostat can be set from 45 to 135 degrees Fahrenheit, giving you full control.

You’ll be able to use this even in outdoor areas like on your patio, giving it extra use cases for any scenario.

The adjustable louvers will also give you the capability of directing the hot air right where you need it.

This electric heater also comes with a high level cutout, preventing any overheating. It’ll even sense when the temperature is back to normal and turn the heater back on.

You can decide to use it on 5000 or 2500w, allowing you to save money should you only need half the heat output.

If you are bothered by some noise, this unit won’t be silent, so keep that in mind.

If you aren’t aware already, you will have to wire this to your electrical system (if you don’t have a 240v outlet). This will add to the price.

For most standard 2 car garages, and considering the rule of 10 watts per square foot, this heater at 5000 watts is going to be more than suitable to keep you warm.

If you need more power for larger spaces like a workshop, you can look into the Dyna-Glo Electric Garage Heater which is capable of heating around 750 square feet.

My biggest gripe with this heater is that it’s a bit plain looking.

Regardless, it has every feature you’d want from a 240v garage heater and doesn’t cost an arm and a leg.

  • Ideal for indoors and outdoors
  • Overheating protection
  • Includes a ceiling mounting bracket
  • Little noisy
  • Lack of a real thermostat

Best Runner Up Garage Heater 240v

Dyna-Glo Electric Garage Heater

Key Features:

  • Heats up to 750 square feet
  • Fully enclosed motor
  • Adjustable angles

Need to heat areas to 750 square feet(or larger insulated areas?)? You can’t go wrong with this 7500w heater.

With its dual power settings, you can choose from 5000 or 7500w depending on how hot you want it to go.

The included fan can be used by itself, making this heater useable during the summer.

What I like about this heater over the others on this list is the LED display.

It has a touch screen as well, making it easy to use. It also comes with a remote control that other units I’ve reviewed lack.

While it may not be important to some, this electric heater is also aesthetic with its black and slick appearance. This heater will make your workshop shine if you don’t fancy dull colors.

The adjustable louvers will let you point the heat right at you so you can stay comfortable while you work.

As long as you or someone you know is capable of wiring this heater to your electrical system, then you’ll love the convenience of the remote control and LED display.

Be careful though as if you have a one-car garage, this heater will be far too powerful. An overly sized heater can cause your heater to lose efficiency as well as make your garage an uncomfortable place to be!

I love the look of this heater, and while it did come in 2nd place, it’s only because of the price tag.

It’s also not for everyone, as only people with a larger workshop (above 500 square feet) should look into purchasing this heater.

  • LED touch screen display
  • Remote control
  • Overheat auto shut-off protection
  • Can be noisy
  • Needs to be wired by an electrician

Best Budget Electric Garage Heater 240v

Comfort Zone Ceiling Mount Heater

Key Features:

  • Crafted from heavy-gauge steel
  • Dual knob thermostat
  • 3 heat settings

Want to feel warm, enjoy a 240v heater and not spend a ton? You can still get away with 5000w of power if you’re willing to compromise on some additional features.

The body of this electric heater was designed to withstand constant temperature fluctuations, making it a great garage heater in extreme climates.

For the price, it still comes with an adjustable thermostat, allowing you to turn off the unit.

Some cheaper units I’ve reviewed don’t let you turn off the unit without an additional thermostat, costing you less money.

You’ll be able to rely on the included overheating protection as well as the power indicator light letting you know if the unit is on.

When installing this electric heater, you can install it in 3 different orientations making it customizable for any workshop.

One downside is that this unit doesn’t come with remote control. The thermostat is analog as well, so you won’t be able to fully dial it into your specifications.

While this electric heater does have some downsides, it’s still great for 2 car garages.

This budget heater will save you a ton of money compared to other 240v electrical heaters that I’ve reviewed.

It is quite plain looking like the Fahrenheat Electric Heater for Garage in first, but it is a killer deal at around $100.

This 240v heater is perfect for anyone who doesn’t want to spend a ton but still be able to spend time in your garage this winter.

  • Built-in overheat sensor
  • Power indicator light

  • Consumes a large amount of energy
  • Thermostat is analog

Runner Up Budget Electric Garage Heater 240v

Dr. Heater DR966 Garage Commercial Heater

Key Features:

  • Adjustable thermostat
  • 5 Adjustable louvers
  • Totally enclosed

Another great budget 240v heater for your garage is the Dr.Heater DR966.

It comes with a whopping 6000w, which is plenty for around 600 square feet.

You can also opt to turn it on to the 3000w setting if you have a 300-square-foot garage.

You can also take advantage of the 5 adjustable louvers that will let you aim the forced heat right where you need it. You can even adjust each one independently which is neat.

The front panel has an adjustable thermostat as well to give you extra control.

Be aware that while the manual says to use 10 gauge wire, it’s better to go with 8 gauge considering the wattage that this electric garage heater uses.

One downside compared to other electric heaters is that the unit won’t turn off unless you have it hooked up to an external thermostat or switch.

As long as you are aware of the type of wire gauge you should use and can get someone to help you wire this (or do it yourself if you’re an electrician), this budget garage heater is another great option.

It costs more than the Comfort Zone Ceiling Mount Heater by a fair bit, but also has the ability to go up to 6000 watts which allows for 100 square feet of more heat coverage.

If you have a larger space and want to save a few bucks this winter, this is the 240 electric garage heater to get.

  • Thermally protected
  • Heavy duty ball bearing motor
  • Ceiling and wall mounting bracket are included
  • Little noisy
  • Power cord not included

Best Wall Electric Garage Heater 240v

Stiebel Eltron Wall-Mounted Electric Heater

Key Features:

  • Heating down-draft design
  • Built-in thermostat
  • Heats up to 215 square feet

A wall electric garage heater is another great option if you’re running low on space.

This wall heater is quiet, running at only 49dB.

You can utilize the built in thermostat that’s built right into the top of the unit.

Coming in at 2000w, it’s perfect for around 200 square feet.

It works by bringing in cold air to the top and warming it, then directing the hot air out of the bottom. This way, your garage has circulating heat that spreads evenly.

What I like about this unit is that you can also opt to use the frost protection setting. This can come in handy if you want to keep your garage above freezing but not run it on full blast.

You can also buy an additional thermostat and control this garage heater right on your wall without any issue.

Like all other heaters on this list, it will need to be professionally installed if you don’t have any experience connecting electric garage heaters.

Overall, if you want a space-saving heater for your garage that is a bit more powerful than a 120v heater, hard to go wrong with this option.

The compact size of this heater makes it great for a one car garage. While it’s made for only 215 square feet, it’s also space saving making it fit in tight spaces.

I wouldn’t go with this option if you have a 2 car garage. For that, I would suggest going with the Fahrenheat Electric Heater for Garage,

  • Quiet fan
  • Frost protection setting
  • On/off switch
  • Not easy to install 
  • Takes time to warm up

Also Great Wall Electric Garage Heater 240v

Broan-NuTone Wall Heater

Key Features:

  • 18-gauge steel white grille
  • Downflow louvers
  • Adjustable thermostat

If you have a larger garage, you can rely on this thin electric garage heater to disappear right where you install it.

It’s capable of 4000w/2000w, which is going to be enough for 300-400 square feet depending on how well insulated your garage is.

You can also opt to choose the 3000/1500W version if you want to use this heater in a 1 car garage.

The front has a thermostat that gives you full control and is super simple to adjust.

It’s easy to install, and can even be wall mounted if you’d like instead of in a recessed space. This way, you won’t need to cut a hole in your garage walls.

The downflow louvers also work to spread the heat around your garage easily.

This garage heater is a fan-forced heater, which means it uses a fan to spread heat instead of being an infrared heater.

One downside of this unit is that you’ll need to have it wired to a shut-off switch, otherwise it will continue running nonstop.

This wall heater is also quite a bit more expensive than the Comfort Zone 5000W budget option which has more heat output.

You’ll be able to heat up a larger space than the Stiebel Eltron Wall-Mounted Electric Heater but the price tag does reflect it.

Compared to other traditional 240v heaters, you do get the benefit of in-wall installation which is great for packed garages.

If you’re ok spending a bit more and don’t have space on your ceiling or floor in your garage, then this wall heater is going to do you right.

  • Permanently lubricated motor
  • High efficiency blower wheel
  • Easy installation
  • Can be noisy

Best Electric Portable 240V Garage Heater

NewAir 2-in-1 Garage Heater

Key Features:

  • 2-in-1 portable or wall mount design
  • Rugged shell
  • Heats up to 500 square feet

You don’t see many portable 240g garage heaters on the market, but this right here is just that.

It’s got a handle on the top to make it easy to maneuver, and you can place it wherever you’d like.

The front has an easy-to-read display, and push buttons for the thermostat.

You can also opt to use it on your wall should you wish to use this as a permanent heater.

It comes with remote control, which not many other 240v electric heaters on this list offer.

If you’re wanting it to turn off while you’re away, you can use the 9-hour timer to do just that.

With 17,000 BTUs of heating power, it’s going to be enough for around 4-600 square feet depending on the insulation in your garage.

One downside is that you won’t be able to hardwire this unit and it will require a 240v outlet.

The fan can get quite loud compared to other heaters as well.

With it coming with remote control and can be used as a portable heater, anyone that is on the go will find great use and be able to keep warm this winter.

It’s hard to find a 240v heater that’s also portable. The biggest downside is that not every place you go has a 240v outlet, which may make this unit a bit less appealing.

If however you’re on the go and have a 240v generator that you bring with you, then suddenly this portable 240v heater starts becoming a much better deal.

  • Automatic shut-off function
  • Mounting bracket and hardware included
  • Remote control
  • Power outlet required
  • Can be quite loud

Alternative Option

Heat Storm HS-1500-OTR Infrared Heater

Key Features:

  • Weatherproof
  • Corded electric
  • Wall mountable

A great alternative to 240v heaters is infrared heaters.

What’s great about them is not only the price, but you also won’t need to use a ton of electricity to use them either.

This unit is going to be great for 150-square-foot garages.

You can buy three of these and it’ll still be cheaper than the cheapest 240v electric garage heater on this list!

You can mount it on a tripod or the ceiling, but it will cost a bit extra depending on your choice.

It’s safer to use than propane heaters and is weatherproof, making it a viable option if you want to use it on your patio as well.

This electric garage heater also has a tip over safety features and won’t turn on unless it’s mounted in a vertical position.

Sadly, there is no thermostat for this unit, so whatever heat output is there is what you get.

You also don’t have an on/off switch to use, so you’ll have to unplug the heater if you wish to use it.

For the price, it’s a great deal as long as your garage is around 150 square feet. You can opt to buy several for your garage if you want to save a bit of cash.

If you aren’t wanting to pay an electrician to hook up a 240v heater, then a 120v one can get the job done in the right circumstances.

You won’t however be able to heat up uninsulated spaces with a 120v heater. If you have an uninsualted space, I recommend looking into cheap insulation options.

  • Easy to set up
  • No ventilation needed
  • Includes 6.5ft cord
  • Doesn’t have a thermostat
  • There is no on/off switch

Alternative Option #2

Dreo Portable Space Heater

Key Features:

  • 12H auto-off timer
  • Adjustable digital thermostat
  • 4 mode settings

Another option for your garage is a standalone space heater. While it isn’t going to heat a large workshop, it’ll be great as supplementary heat.

It comes with an adjustable thermostat and even has a 12-hour timer.

The front has an awesome LED display with touch controls. It’s super quiet as well running at only 40dB.

Fear not with this little space heater as it comes with tip-over protection as well as overheat protection.

You can also opt to use the 3 heating modes that can turn this heater into a low wattage space heater.

What’s also cool is that it has 70-degree oscillation, allowing for the heat output to spread around the room.

The biggest downside to a heater like this is that it won’t be able to heat larger garages.

The biggest benefit is that you can get it right near you, making it great as a hand warmer while you’re tinkering away at your workbench.

While it isn’t going to be a replacement for a large garage heater, this little space heater is going to do well in smaller garages of around 150 square feet.

Make no mistake, this is no replacement for a 240v heater. If you don’t want to spend a ton of money and only stay a little warm this winter, then I’d recommend to go for this option.

If however you want your entire garage to be warm and toasty, I’d recommend the budget option: Comfort Zone Ceiling Mount Heater.

  • Cold-to-touch housing
  • Energy saving
  • Space saving
  • Noisy
  • Thermometer seems a bit off

What to Look for in a 240v Electric Garage Heater?


By following the 10 watts per square foot rule, you’ll need to get around a 4000W heater for a 400 square foot garage.

Keep in mind that a 1500W heater is only going to be suitable for around 150 square feet, or a one-car garage.

If you have a larger than 400 square foot garage or your garage is uninsulated, you’ll need more power to keep your garage warm.

Many 240 electric garage heaters can use lower wattages if you prefer, giving you flexibility with how hot they can get.

What’s important is that you purchase the heater that is sized correctly for your garage.

Too large and it will cause high energy bills as well as overheat your garage, too small and it won’t be able to keep up.


Most 240v heaters should be able to be wired directly to a thermostat on your wall.

This way, you can easily control your 240v garage heater without having to get on a ladder.

Not all heaters can be turned off (unless wired to a switch), so be mindful that you may need to wire your 240v heater to an on/off switch as well.

Look for a 240v heater that has an on/off switch if you don’t plan to purchase an additional thermostat.

Safety features

Safety features like tip-over protection and overheat protection are important to consider.

You never know what may happen while you step away for a second, so it’s vital that your heater can shut itself off if anything goes wrong.

If you have children around and are using a floor 240v heater, it’s even more important to get one that can turn itself off if tipped over.


You’ll be able to find 240v heaters from $100 into the thousands. The more expensive options are capable of heating larger spaces and come with extra features.

Products like the Comfort Zone 5000W are capable of heating 500sq.ft insulated spaces all while staying within the budget price range.

You’ll miss a few features from the lower price point, (like how the heater looks), but if it doesn’t bother you, then you won’t need to break the bank to get a decent heater.


If you’re on the go, you can opt to use a portable 240v heater like the NewAir 240v Heater.

You can take it with you, the only downside is that you’ll need to use it on a 240v outlet.

Most 240v heaters are going to be standalone, so you’ll need to hardwire them to your electrical system. But you can still benefit from the heat output of a 240 heater over 120v and enjoy the portable factor.

Are 240-volt heaters more efficient?

240v heaters are no less efficient than 120v heating. 240v is a better option to heat larger garages because of the amperage capabilities.

How many Watts for a 2 Car Garage?

The rule is for every 10 square feet, you’ll need 10 watts. So for 400 square feet, you’ll need a 400 square foot heater.

Is a 240v Heater Enough for a Garage?

A 240v heater should be more than enough for a garage (unless the space is uninsulated).

With the ability to output far more wattage than a 120v heater, you should be able to find the right size heater for your workshop.

How many Square Feet can 5000W Heat?

5000 watts should be enough for 500-square foot space.

Final Thoughts

Looking for the best 240v electric garage heater?

The best I could find was the Fahrenheat FUH Electric Heater. With its ability to heat up to 400 square feet (or more if insulated well), price and safety features, it’s hard to beat.

A budget option to consider is the Comfort Zone 5000W. It’s capable of outputting 5000W and it’s still affordable as heck.

Don’t sleep on 120v garage heaters or torpedo heaters. They’re both viable options to keep you warm this winter in your garage.
