Best 120v Garage Heaters for 2021 [Keeping Your Garage Warm]

Are you looking for a heater to keep your garage or shop warm? There are tons of different 120v electric garage heaters out there, and it can be overwhelming to weigh the pros and cons of each one in a sea of options. 120v heaters can be ceiling mounted or are offered in a basic standing design.

Understanding the voltage and heat distribution you need in your specific garage is the key to finding a heater to get the job done right. We’ll take it from there and discuss the pros and cons of quality space garage heaters to help you choose the right heater for your garage.

What Size of Electric Garage Heater Do I Need For My Garage? Is 120v Enough?

120v is a fairly small heater, but it’s going to get the job done for a smaller space. If you have a garage larger than 30 x 30 feet or a garage that is not well insulated, you may need a higher voltage to keep it at a comfortable temperature in the winter months.

A 220 volt is actually designed for commercial spaces, so if you’re trying to heat a medium-sized space, it might be worth investing in two 120v garage heaters. 120/110 volt power outlets can be switched between 15-20 Amps before the power outlet is affected.

Check to see if your garage has a single breaker that manages all of your lights and outlets, or two or more breakers that manage different outlets and lights separately.

How Do I Choose a 120V Electric Garage Heater?

When buying an electric garage heater, keep the following features in mind for the heater:


A large heater for a small garage or a small heater for a large garage are both incorrect. The former would simply be a waste of energy, while the latter would provide insufficient heat output. So, make sure you find a heater that fits the size of your garage.


The thermostat should be in good shape, and heat productivity must be what the company claims, or it will be just a loss of money. This can be assessed by viewing customer feedback on the product you are planning to purchase.

Price-to-Feature Ratio

Better-performing garage heaters with higher features may be a bit more expensive, but they will certainly provide comfort for a longer period of time with greater consistency and efficiency. On the other hand, a cheaper heater may cause discomfort by failing to deliver expectations. However, this can be better assessed with the help of feedback from customers and research.

Types of 120V Electric Garage Heaters

120V electric garage heaters come in a variety of types. Some of the most commonly used include:

Infrared Electric Garage Heaters

These garage heaters work by heating up not only the air, but also the objects around them. This feature enables it to be energy efficient as the room or garage where the heater is working remains warm long after it has been turned off. It works by emitting electromagnetic radiation called infrared heater rays, which are quite similar to the rays coming from the sun.

Electric Fan Heaters

Electric fan heaters are often used in garages as they are budget-friendly for most people. They work by passing the air over a heating source and then circulating the heated air in the room. The most obvious disadvantage of such heaters is the noise they produce, which, however, is being overcome by the advancement of technology.

Electric Underfloor Heating System

Although electrical underfloor heating systems have a very expensive installation, their long-term working costs are consistent with those of other types of heaters. They are very efficient and work by turning the entire floor into a radiator.

Garage Heater Electric vs. Gas – Comparison Overview

Both gas and electric heaters help to battle the cold weather. However, certain distinguishing factors between the two are:


The installation of a gas heater is a time-consuming process that requires expert service. It’s a lot more expensive than an electric heater, which requires little or no installation effort.


Maintenance of an electric heater requires no expert knowledge and experience, no one can do that. However, the same is not the case with a gas heater. Their annual maintenance is essential to ensure that they operate properly for longer periods of time and avoid unpleasant accidents such as gas leakage.


The lifespan of the electric heater, which is about 20-30 years, is much longer than that of the gas heater, which is about 10-20 years.

Which is Cheaper to Run, a Gas or Electric Garage Heater?

The value of the heater cannot be determined solely on the basis of its operation. All other costs, such as installation and maintenance, matter a lot as well. However, on the basis of running costs, the gas heater is cheaper than the electric heater. That’s because natural gas is cheaper than electricity.

120v vs. 240v Electric Garage Heaters

Are you going to buy a 120v or 240v heater? This is a question that most people keep asking, and while there are many good-meaning answers on online forums, most of them are misleading.

If you have two heaters, one 240v and the other 120v, both of which have the same watts per sq. ft. (12w/sf is the industry standard), both products will use the same amount of power and watts.

The reason is that the 120v system draws twice the amp/sq.ft of the 240v system, while the 240v system draws half the amp/sq.ft of the 120v system. According to Ohm’s law, power is equal to the product between voltage and current (amps).

For example, if you want to heat a 100 sq. ft room, both systems will use 1200 watts, and since we know the voltage, we can determine the current or amp for each unit.

Amps for the 240v heater = 1200 watts/240v = 5.0 amps.

Amps for the 120v heater = 1200 watts/120v = 10 amps.

Thus, while the 240v may appear to have twice the power, it produces the same amount of heat per sq. ft as the 120v heater, heats up at just about the same rate and can cost approximately the same amount per sq. ft to heat your space.

It is recommended that you use 120v electric garage heaters in spaces below 150 sq. ft. and 240v heaters for spaces above 150 sq. ft. This is because a single thermostat is capable of controlling 15 amps.

Going with our previous example, 120v can draw at least 15 amps across a 150 sq. ft space, and so manufacturers can supply 240v heaters for larger spaces.

More importantly, you want to ensure that the voltage of your garage space heater matches the voltage of your power supply. This is particularly important if you want to replace the current heater.

If you misalign the voltages, you will only receive 25% of the heat, and it could be unsafe as well. For example, connecting a 240v heater to a 120v power supply will only give you 25 percent of the heat that is not efficient.

(120v/240v)2 = 25%

Connecting a 120v electric garage heater to a 240v power source, on the other hand, is likely to overload the system, damaging the heater and its thermostat. It will also result in costly reinstallation.

(240v/120v)2 = 400%

In some cases, however, you may be forced to misalign the voltages between your heater and the power source. Standard power supplies are 120v and 240v, but some people’s indoor supplies are rated 208v. In this case, you can connect a 240V heater to a 208 power supply. Note, however, that the heat produced will be lower by 25%. In other words, the unit will run at 75% power.

(208/240)2 = 75%.
