How To Choose the Right Garage Heater for You

Choosing the right heater depends on your personal needs. Where are you going to put it? Does it need to be portable? What about your budget? Here’s what to pay special attention to.


The best electric heater for garage 120V use is not necessarily the most expensive. However, you’re looking to spend between $80 and $300 depending on power, reach, and other features.

The most expensive unit reviewed is the AirNmore Comfort Deluxe, with a starting price of $277. It can heat up to 600 square feet and has a touchscreen panel. The cheapest is the Aikoper Space Heater, at just $79.99, which has about the same reach and oscillates!

Wattage and Temperature

Wattage is, in effect, raw power. In most cases, the higher the wattage, the higher the potential temperature of your heater. Electric garage space heaters typically range between 900W and 1,500W. You might even be able to set the wattage as an alternative to a temperature thermostat or in conjunction with one - for example, ECO mode.

To know how much hot air you can expect, pay attention to the temperature range and reach. For example, the Broan-NuTone 9815WH reaches 350 square feet.

Room Size

120V allows sufficient power to heat most medium size garages and other spaces. Of course, before making a purchase, you should measure the room’s dimensions and check it against the heater’s advertised reach.

Also, consider your intended use, as it’s not always necessary to warm up an entire room or area. This is often true for outdoor use when it focuses only on a specific space.  While at the same time, make sure you aren’t trying to heat an 800 sq. ft. space with a 150 square foot solution, as the results will be less than satisfactory. 

In short, make sure you right-size the device to its intended location and use. 

Mounting vs. Standing

You can wall-mount heaters, ceiling-mount them, or stand them anywhere on the floor. The best portable electric garage heater with 120v is free-standing and may even have wheels, a carrying handle, or both. 

Mounted ones are for more permanent locations. 

Heat Spread

You must also consider how it spreads the hot air. For example, an oscillating heater spreads the heat evenly in a semi-circle and is excellent for gatherings or warming entire rooms.   

Long wall-mounted devices effectively spread hot air across rooms. 

Some models will even let you change the angle of the fan to focus the direction of the heat.  

The TPI Corporation OCH46 is particularly good, thanks to its 60-degree symmetric pattern.


Whether looking for the best heater for an uninsulated garage, an RV, or anywhere else, safety is paramount. At the least, you want an automatic shut-off if the device gets too hot or falls over. Some models have cold-touch technology, so you don’t feel any heat on the unit. This is important if you have pets or children around who may carelessly touch it.

Other units will switch off if there’s a blockage or lack of oxygen.

Remember to follow the instructions about placement. It should be free from obstructions. 


You want an easy way to control your heater, especially if it's for lounging in a makeshift man-cave. Many devices come with remote control, while others stick to physical controls.

With the advent of smart technology, some even allow remote control via a mobile app rather than a physical remote.

We advise choosing one with actual temperature controls, not just wattage settings or high/low modes. 

Other Power Sources

We focus mainly on 120-volt electric garage heaters, however, other power sources are useful, especially if on the move. For example, Mr. Heater F274830 MH18BRV can also use propane when you’re spending time in the RV. 

Propane is generally more efficient at heating than electricity, which can usually only achieve temperatures below 90F. However, propane devices can reach temperatures up to 140F, ideal for those extra cold nights. You can expect to pay more for a high-quality propane heater. As such, it might not be worth it if excessive heat energy isn’t necessary.   

Build Quality

Many cheap electric devices often stop working after a few months. That’s why we picked only the best options when considering build quality. Look for quality metal builds from aluminum or steel. Also, consider copper instead of regular heating elements. Additionally, take note of durability ratings and weatherproofing if intending to use outdoors.

Energy Efficiency 

Electrical energy efficiency is the power consumption vs. the amount of heat produced. Being efficient is good for the environment and the pocket. Most devices come with an ECO mode and allude to their energy efficiency. Like all electronics, prolonged use will impact your energy bill.  


Most heaters use a fan to distribute hot air more effectively. But what else is a fan good for? Cooling! Believe it or not, some can double up as cooling fans. So be on the lookout for this feature if living in a region with four seasons.  

Wrap Up

We hope you’ve gained more insight into warming your garage and can identify the best electric garage heater at 120V. Whether you want something that’s wall or ceiling mountable, will sit stable on the floor, or oscillate - you should now be able to find the best electric garage heater
