How We Picked the Best Electric Garage Heaters

Choosing a list of the best electric heaters was quite a task. We wanted to ensure that whatever models we chose for their respective awards were truly up for the job. We had to consider all our experience with electric heaters, garage heaters, and specific models to determine which features and functions the average garage or workshop would need. This was a good starting place.

Once we knew which features we needed, we performed extensive product research to compile a list of models we thought would hit the marks. We considered our personal experiences (with most of the models on the list), customer feedback on the best-rated electric garage heaters, pricing, and functionality to ensure that each model we chose provided enough value. The electric garage heaters that didn’t provide enough value were removed, while those that did were given awards based on their best uses or specific functions.

Best Electric Garage Heaters Buying Guide

The only thing you’ve decided on is that you’re turning to an electric heater to warm your garage. But beyond that, there are a lot of points to consider when choosing the best electric heaters for garages. 

Size and Heating Capacity

Calculating the right wattage for your space

There is a consensus that you can calculate the amount of wattage needed from an electric garage heater with a simple formula. Measure the length and width of the garage space to find the square footage. Then, multiply that number by 10 to find the required wattage.

So, for a 24 by 24 garage:

  • 24 x 24 = 576 feet
  • 576 x 10 = 5,760 watts

In this case, a 6,000-watt electric heater will do the job. However, keep in mind that if a garage has high ceilings or very little insulation, it can be difficult to nail down the required wattage. This is just a rough estimate, and smaller heaters can help raise the temperature in these spaces quite a bit, they just might need to work harder and more often to keep up. 

Understanding BTU ratings and their significance

BTUs, or British Thermal Units, are equal to the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit. However, when it comes to electric garage heaters, we can use BTU as the unit of measurement that describes the heater’s output. The larger the number, the higher the heater’s output. 

Generally speaking, even the best electric heaters for garage spaces don’t produce as many BTUs as those that use combustible gasses. However, an extremely high-output electric heater can produce more than 35,000 BTUs, while smaller heaters might only produce around 5,000 BTUs.  

Heat Type

Forced Air vs. Infrared vs. Convection

There are three main heat sources for electric garage heaters: forced air, infrared, and convection. Each works very differently, but it’s worth understanding them before choosing a model.

Type Description
Forced Air Forced air heaters feature powerful built-in fans and electrical coils. As the coil heats up, the fan draws cool air in from the space and blows it past the coil, heating the air and pushing it into the room. These units are typically loud but can heat a space quickly.
Infrared Infrared heat works by emitting infrared rays and heating the objects and people within the space, rather than the air. Once the objects in the space are warm, they can start to emit heat as well. These models work well in localized spaces and they’re quiet, but they can take a while to heat an entire garage.
Convection Convection heaters work by emitting heat upward. The warm air produced by the heater rises, pushing colder air down. The heater then warms the colder air, pushing it upward, and pushing colder air back down in a cycle. These models are silent and heat evenly, but they may struggle to heat a cold garage quickly.

Energy Considerations

Efficiency

electric meter

Inefficient electric garage heaters can really spin the electric meter when the temperatures drop. Rather than letting that heater put you in the poorhouse, look for one that’s relatively efficient. Keep in mind that Energy Star, the leading authority of efficiency, doesn’t qualify any space heaters, so it’s best to look for a model with energy-saving features.

Features that boost efficiency

When energy efficiency is a priority, look for electric garage heaters that offer:

  • Timers
  • Apps 
  • Thermostat compatibility

These features allow the user to choose how often or how hard they want their electric garage heater to work. They can turn the heater off when they’re not in the garage, set it to a temperature that simply keeps the garage space from freezing, or even program schedules to turn the unit on and off at specific times. 

Understanding Voltages 

Electric space heaters are available in a few different voltage ratings, including 110, 120, 208, 220, and 240 volts. The higher the voltage, the potentially more powerful the heater. 

Standard household outlets produce 110v or 120v power. Generally speaking, differentiating between the two isn’t a big deal. A 120v device will work in a 100v outlet, and vice versa.

However, large appliances like air conditioners, dryers, and electric ovens require more voltage (208v, 220v, or 240v). The same applies to powerful tools like welders, as these devices also require more voltage.

When it comes to electric heaters, smaller models can typically plug into a 120v outlet. The best 120v garage heaters are ideal for smaller garages or regions where the temperatures don’t drop extremely low. However, large heaters often need to be hardwired into the home’s electrical system on a dedicated 30-amp circuit. They can also be fitted with appliance cords and plugged into specific 30-amp outlets. 

Installation and Portability

Wall- or ceiling-mounted vs. freestanding options

garage heater installation

When it comes to electric garage heaters, there are two options: mounted or freestanding. Mounted units attach to the wall or ceiling, and they stay up and out of the way. This is a big help in a busy workshop. However, freestanding units are portable and able to move about the garage, allowing users to put the heater right where they need it most.

Portability features

To help make these freestanding models a bit easier to shuffle around, the best portable electric garage heaters include carrying handles. Users can lift these heaters by their handles, often while they’re still hot (be sure to check the owner’s manual). 

Some electric heaters made for garages might also feature wheels that allow them to roll across the garage floor. These options may be the best electric space heaters for garage spaces owned by older folks or those with physical disabilities.

Thermostat and Control Features

Built-in thermostats like the one on the Vornado VMHi600 enable you to customize the temperature and increase the unit’s efficiency in the process.

Importance of an adjustable thermostat

Thermostats are incredibly important when it comes to electric garage heaters. These devices tell the heater how warm to make the space, preventing the user from overheating the space unnecessarily. But, thermostats also allow the heater to turn on when the temperature starts to drop and turn off when the set temperature is satisfied, saving energy over the unit running continuously. 

Remote controls and smart features

Aside from a standard thermostat, some electric heaters have remote controls for easy setting and turning on or off. Even more advanced are those with Bluetooth or WiFi compatibility, which users can turn to for controlling and monitoring their garage heater. These apps can often set schedules, as well. 

Maintaining Comfort in Cold Seasons

Keeping a garage space warm in the winter allows DIYers to take on projects that might otherwise have to wait until spring. For example, any project involving paints, adhesives, plastics, and other materials that don’t respond well to the cold doesn’t have to wait until the warmer months.

Also, cold weather tends to affect coordination and motor skills, making smaller projects very difficult to handle. With a warm garage space, there’s no reason why the user can’t fire up the electric garage heater and get to work.

Protecting Equipment and Supplies

Some items that people typically keep in a garage shouldn’t freeze, and a garage heater can prevent it. Glues, paints, jarred foods, and other items could become damaged or useless if they freeze, so it’s a smart move to have an electric garage heater that can keep the space above freezing.  

Safety Considerations When Using Electric Garage Heaters

Overheat Protection and Auto Shut-off

Electric space heaters don’t produce dangerous gasses like combustible fuel heaters, but there are still certain safety devices they should include. 

Many of the best-rated electric garage heaters feature overheat protection, which shuts the unit off if the temperature gets too high. Others include tip-over switches, so the unit will shut off if the heater falls over. Other safety features might include cool-touch handles or exteriors, or timers that ensure the unit shuts off even if the user forgets. 

Proper Clearance

Electric space heaters need to have enough space around them for airflow (particularly forced air models). Otherwise, they’ll heat the air in their direct vicinity, never allowing convection to take place and shutting down when the thermostat setting is satisfied. 

Also, keep these heaters far from flammable items. The general rule is to keep space heaters at least 3 feet  (5 is better) from flammable items like paints, solvents, fabrics, paper and cardboard, and similarly flammable items. 

Regular Maintenance and Inspection

Checking for wear and tear

Be sure to check your heater for wear and tear. While electric heaters don’t require as much maintenance as fuel-burning heaters, they should still be inspected for frays in the power cord, dents, broken switches, and other items that could create a hazard.

The risks of using a faulty heater

It’s important to fix or replace a faulty heater right away. Damaged electrical devices can behave irregularly, potentially causing fires or electrocution. 

Frequently Asked Questions About Electric Garage Heaters

How much does it cost to run an electric garage heater?

The cost to run an electric garage heater depends on the heater itself, the volume of the space being heated, the temperature outside, the garage’s insulation value, as well as the desired temperature inside. However, most real-world data provided by garage heater owners suggest between $0.75 and $1.40 per hour. 

Are electric garage heaters safe to leave on overnight?

Most modern electric garage heaters are safe enough to leave on overnight. Just be sure that there isn’t any potential for the unit to fall or for something to fall on it. Also, be sure to use the thermostat. 

How can I maximize the efficiency of my electric heater?

Efficiency and consumption are two different things. Electric garage heaters, or all garage heaters for that matter, aren’t extremely efficient. However, using a built-in timer to turn it on and off as needed, lowering the thermostat, and making sure the space is as insulated and well-sealed as possible will help the most. 

Can I install an electric garage heater myself?

It depends on the model. Many electric garage heaters use 208 to 240v electricity and need to be hardwired into the home’s electrical panel. For these projects, most jurisdictions require an electrician’s license. However, the act of assembling and installing an electric garage heater’s brackets is well within the capabilities of a DIYer.

What’s the difference between radiant and forced-air garage heaters?

Radiant heat is emitted into the space, heating the air around the unit. The warm air rises, pushing the cold air downward where it is heated and the cycle continues naturally and evenly. This is called convection. Forced air heaters have powerful fans that draw cold into the fan and push it across a heated coil, forcing hot air to disperse throughout the garage.
