Best Electric Garage Heater 120v - Buyers’ Guide

If you are reading this, it means you have already read our review of some of the best garage heaters in the market. If you haven’t, it is not that much of a big deal because, in this section, we will be covering a vital topic.

1. What types of Electric Garage Heaters? 

Here, we will be looking at the various things to look out for when buying a 120v Garage heater. Before we go on, you have to understand that garage heaters can be categorized in two ways.  The first one being in terms of portability and the other in the mode of heating.

1.1. Categories of Electric Garage Heaters: Portability

In terms of portability, we have two types of garage heaters; Portable heaters and Fixed electric heaters.

  • Portable heaters

Portable garage heaters can be lightweight units that are easily moved around. To a large extent, these heaters are the easiest ones to use. This is mainly because no wiring is needed for the heaters to run. In fact, in most cases, assembly isn’t even required.

All you have to do is find an excellent spot for it in the garage. Plug it into the proper outlet. Then, turn it on.

  • Fixed electric heaters

Fixed electric garage heaters are mounted to either the sides of the garage or ceiling with fasteners. They are also often needed to be connected to the electrical system of the house. In other words, professional help might be needed.

1.2. Categories of Electric Garage Heaters: Style of heating

In this category, we have three main types of heaters; radiant, convective, and micathermic type of heaters.

  • Radiant Garage Heaters

This is by far the most used type of heating mode for electric heaters. They work by using electro-magnetic waves in transferring heat energy into objects in the room.
This style of heating is great for warming up large spaces. They also generate quick heat.

  • Convective Garage Heaters

Convective heaters use a current passed through an element. When the element reaches a high temperature, some of the heat is released to the air. This air is passed through the heating unit. Warm air is released from the unit. Then, cool air enters it to be warmed.

  • Micathermic (Mica) Heaters

The Micathermic heater uses a heating element that is surrounded by a heat-conducting stone called mica.

The mica plays an essential role in helping the heater pass heat waves from the heating element to other parts of the room. Mica also produces electro-magnetic waves on heating. Just like with the radiant heater, these waves also warm up the room even further.

2. What should I look for When You Choose an Electric Garage Heater 120v?

As you may have seen, the 120-volt electric garage heaters are in different options. Making a choice may be a bit of a hassle. This is why we prepared a buying guide that will help you make the right decision. Before buying a 120v electric garage heater, here are some things to look out for

2.1 Wattage/BTU

Not all 120volt heaters come in the same size. While most of them are rated at 1500 watts, you may come across other models rated as low as 1200 watts and even as high as 2500 and 4000 watts. If you see the term ‘BTU’ instead of watts, do not be confused. BTU is another way to calculate how much heat the heater can generate. One watt = 3.41 BTU.

2.2 Size of the garage

This is very important. The standard 120v electric garage heaters are rated at 1500 watts. This is only ideal for spaces less than 150 square feet. The great thing is electric garage heaters display recommended coverage areas to help you in making the best choice.

2.3 Safety Feature

Generally, electric garage heaters are safer options than garage heaters that are powered using combustible energy. However, it is important to note that some electric garage heaters are safer than others.

The garage heaters listed in the review have some inbuilt safety features that prevent the risk of fire outbreak. However, some other things should be taken note of. For instance, having a ceiling mounted heater is a great choice if your children or pets play a lot in the garage.

Also, models that keep users’ hands away from heat are not a bad choice. These models will help reduce the risk of skin burns.

2.4 Ease of installation

Garage heaters that are fixed are a lot harder to install than portable heaters. You may need to employ the services of an electrician to install the heater. If you do not intend to spend more money and valuable time on installation, the portable model is an ideal option.

2.5 Ease Of Maintenance

Maintenance is another thing that you should consider when you want to purchase an electric garage heater. No one wants to bear the extra costs of a repairman if the heater needs maintenance. The easier it is to maintain, the better for you.

Opt for models that can easily be opened up. One way to know if a model is easy to maintain is if it comes with a mini set of tools designed specially for fixing simple maintenance problems.

2.6 Cost

Another thing that you should consider when you want to buy an electric garage heater is the cost. The cost of having a garage heater does not end over the counter. There are adiitional costs like cost of installation and electrical bills that you have to factor into the equation.

2.7 Overheat Protection

Also, look for units that offer Overheat Protection. For most units, this feature turns off the machine when it starts to overheat. This will prevent your machine from getting damaged early.


The clear winner for this roundup is the Dr. Infrared Heater Portable Space Heater, 1500-Watt. It is the better choice when compared to the other electric garage heaters in the review. No other heater provides the level of quality this product produces. It is conducive for both large and small garage spaces. It produces radiant heat. In other words, objects instead of air are heated. The heat quantity produced by the heater can be toggled with using the inbuilt thermostat and the remote control that comes with the heater.

The only other product that comes close is the ‘Value for Money pick”. The Lasko Pro-Performance High-Velocity Utility Fan is one hell of a product that offers the same positives that our editor’s pick provides (and more). It would have been our editor’s pick, if not for how expensive it is.

However, you will be getting value for your money if you purchase it. It is a high-velocity blower that does more than heat up a room. For something so small, it works with so much power.

The Multi Fun Electric Portable Ceramic Space Heater is cheap and high for small spaces. However, if you want something that is not that expensive but still packs a punch, our budget pick ( the ISiLER Space Heater 1500W) is a great choice. It is the relatively cheapest of the bunch. However, it is excellent for large garages.

All in all, the electric garage heater is an excellent purchase for anyone who spends most of their time in the garage. This probably being due to their intense love for their automobiles or other hobbies that require the use of the garage. Also, the garage heater can be used in different spaces (particularly the portables) during .the cold winter months.
