Education: What You Need to Know Before Buying
With the electrical heater reviews covered, let’s now focus on choosing the best 120v garage heater for your application. The following considerations should help you make an informed decision.
Is 120-Volt Enough?
To be honest, a 120v electric garage heater is a fairly small-sized heater. So only buy this type of heater for small spaces. For garages (or an area) larger than 30 x 30 feet, you’d need something bigger.
You’ll especially need a bigger infrared heater if the area is poorly insulated. A 220-volt electric heater would be ideal in some larger applications.
However, remember that 220-volt electric heaters are designed for commercial applications. They generate a lot of heat. If you’re dealing with a medium-sized garage, a possible solution would be two 120-volt space heaters.
Also important to note is that 120-volt power outlets can take up to 20 amps. Beyond that point, safety becomes an issue.
Therefore, if you’re dealing with a heavy load (more amps), check if the garage or the area you intend to heat has two circuit breakers. If there’s only one breaker, it’s advisable to call an electrician to help with some wiring.
Types of 120v Garage Heater
There are two broad ways to categorize electric garage heaters (no matter the BTU rating) – by mode of heating and by portability. With regards to portability, there are two subcategories; portable and fixed.
Portable heaters are light units that can be moved around with ease. Often, they stand on feet and can be placed in any location as long as there’s sufficient clearance.
These heaters are also some of the easiest to use, mainly because no wiring is required. In many cases, even assembly isn’t required.
Upon purchasing the infrared heater, all you have to do is find the right spot for it, plug it into the proper outlet, and turn it on to begin heating. The majority of electric garage heaters 120v fall in this category.
On the other hand, fixed electric garage heaters are either wall mounted or ceiling mounted. In most cases, the garage heaters are also meant to be hardwired to the home heating system.
As such, professional installation might be required. With regards to the mode of heating, there are three main subcategories, including radiant, convective, and micathermic.
-
Radiant Heaters
The most popular heating mode among electric garage heaters, radiant heating, involves electromagnetic waves to heat objects.
The waves, which carry heat energy, transfer the energy to objects they encounter on their path.
This is different from convective heating, where the heat produced is transferred to the surrounding air such that objects (including you) absorb the heat from the warm air.
Since radiant heat is only transferred to objects and not the surrounding warm air, the heating mode is very efficient, especially in a large garage.
Radiant heaters also generate heat quickly. The only downside is that they are more expensive than comparable convective and conductive models. Infrared garage heaters are the most common type of radiant heaters.
-
Convective Heaters
In convective heating, a current is passed through a high-resistance electric element. As the element heats up, it releases some of the heat to the air passing through the electric heater.
The hot air is then pushed out of the unit and into the entire garage while cold air enters the unit to be warmed.
In some cases, the movement of cold air into the portable garage space heater and warm air out of the electric heater happens naturally through convection (thus convective heaters).
However, to accelerate the process, most of the 120v heaters employ built-in fans to blow air out and distribute it evenly throughout the entire garage.
-
Micathermic (Mica) Heaters
Mica heaters are different in three ways. First, they don’t have a blower. Secondly, the heating element is more powerful than that used in convection heaters.
Lastly, and most importantly, the heating element is surrounded by a special heat-conducting stone known as mica (thus the name micathermic).
Mica plays a vital role in the working of a micathermic heater. It helps the infrared heater to relay heat from the heating element to different areas and keep the room warm.
Additionally, mica produces electromagnetic waves when heated. These waves are used to further heat up the room. In the end, therefore, you end up with both convective and radiant heat.
Factors to Consider When Choosing Garage Heaters
Since 120-volt heater for your garage comes in a wide range of styles and options, you must make your choice wisely. We recommend that you prioritize the following considerations;
1. Wattage/BTU
Just because you’re buying 120v electric garage heaters doesn’t mean that all the units come in one size. On the contrary, 120-volt electric heaters come in many different sizes.
Most are rated at 1,500 watts, but you’ll easily come across models rated at 1,200 watts, 2,500 watts, 4,000 watts, and so forth.
Some are also rated in British Thermal Units (BTU) – one (1) watt = 3.41 BTU. The greater the wattage or BTU value, the more heat output the electric heater delivers.
2. Size of the garage
How much garage floor space are you looking to heat? Is it 300 square feet, 500 square feet, or perhaps more or less?
A standard 120-volt heater for your garage rated at 1,500 watts (approximately 5,200 BTU) is ideal for spaces between 400 and 600 square feet.
The coverage also depends on factors such as insulation, ceiling height, and how much heat needed. The good news is that electric garage heaters display the recommended coverage area on the product label to help you make the right choice.
3. Ease of installation
You get to choose from portable and fixed (ceiling or wall mounted) installation options. Unfortunately, fixed 120v electric garage heaters are more difficult to install.
Moreover, since they’re often hardwired, you might need to hire a professional electrician, which is additional maintenance costs.
A portable model would be ideal if you are not prepared to spend significant time and money on installation.
4. Convenience controls
Features such as digital displays and remote control make it much more convenient to control the climate in the garage space or floor space you’re heating.
An adjustable thermostat is another control to consider. Also, check if the portable space heater has a timer function. Timers allow you to program the heating for the desired period, say a few hours.
Once the set period ends, the electric heater goes off automatically.
5. Safety features
Finally, make sure that the electric heater is built for safe use. One of a safe electric garage heater hallmarks is certification or listing by a recognized laboratory such as the UL, CSA, or ETL.
Aside from certifications, check for safety features such as anti-tip protection, overheating protection, and a cool-to-touch exterior.

Electric Garage Heater 120v Maintenance
After you buy the Heater, the next step is to keep it working optimally for a long time. As such, maintenance is imperative. The following tips should help keep your Heater in top shape.
-
Dusting
A lot of dust and other particles will likely settle on the 120v heater during use. Dust it once a week to remove any foreign particles.
-
Remove grime
Use a damp microfiber towel and a little dishwashing liquid to wipe away the grime.
-
Vacuum
For garage heater 120v with vents or grilles, vacuuming regularly will help clear airflow. The same applies to fan heaters.
-
Wipe heat reflectors
Radiant heaters often use a reflecting surface to direct heat. Unfortunately, these surfaces become dusty too. Periodically, unscrew or unclip the grille protecting the reflector plate and use a towel to dust off the plate.
-
Remove rust
The reflector surface can also catch rust, especially if not dusted regularly. Use rust remover spray or scrub the surface to remove the rust.
Remember to turn off the Heater and allow it to cool down before you begin any maintenance activities.
Final Thoughts
Finding great best electric garage heater 120v shouldn’t be difficult. Just make sure you’re choosing the right type (radiant, convective, or micathermic) while keeping portability in mind.
Also, take into account the wattage (or BTU), convenience controls, and safety. Finally, to keep the Heater in top shape and optimally functioning for a long time, dust, vacuum, and wipe the electric heater regularly.
