What Size Do I Need For My Garage? Are 120v Enough?  

120v is a fairly small sized heater, but will absolutely 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 something with a higher voltage to keep it at a comfortable temperature in winter months. A 220 volt is really designed for commercial spaces so, if you are trying to heat a medium-sized space it may be worth investing in two 120v heaters.

120/110 volt power outlets can take on between 15-20 Amps before the power breaker is affected. Check to see if your garage has a single breaker managing all of your lights and outlets or two or more breakers managing different outlets and lights separately.

Review of the Best Ceiling Mounted Garage Heaters

Below you will find in depth reviews of the top ceiling mounted garage heaters. We take a look at the best currently on the market and give you a review on each one.

  • Pull cord makes it easy to use
  • Wall/ceiling mount design saves space
  • Halogen light to illuminate your workspace


  • Control panel is not well designed

Two heat settings (600/1200 watt) provide sun-like heat, as well as a soft light. The heater also contains quartz heating elements, halogen lights, and a pull cord for ease of use. The heater is constructed with a metal housing and bracket for long lasting life and the unit contains overheat protection.

Comfort Zone CZQTV5M Ceiling Mounted Radiant Quartz Heater with Halogen Light Included - 2pk


  • Energy efficient
  • Two power settings
  • Durable metal housing
  • Adjustable angle for the light and heat
  • Ceiling mounted design is both safer and space saving


  • Control panel is confusing and poorly designed

This ceiling mounted heater is controlled with a single pull string, which operates both heat settings, as well as the halogen light. It can be used without having the light on so the heater works independently of the light. It has the necessary safety features to keep you secure in your garage, such as an overheat protection sensor, safety metal grille, and a three-prong grounded plug to protect from electrical risks.

The ceiling mount for this heater gives you extra safety, security, and floor space. Best of all, the adjustable tilting bracket for this heater lets you point the heater in any direction to provide you with targeted warmth wherever you need it.

Bottom Line:

This is a great combined heater and light for your garage, as it lets you heat up any part of the room where you need it, and stay warm while working in cold weather. Being both energy efficient and durable, you’ll find this heater to be a very good value.

  • Consistent heat in its range
  • No need to worry about fan power
  • Provides good output in its limited range
  • Ideal for over a workbench or other area where you work


  • Limited range - it’s not going to heat a room, just a space

Held by a 90 degree vertical tilting arm with a durable metal housing and high-efficiency quartz heating element, this is a great pick for heating your shop or garage. While it is not great for sub-zero or below freezing temperatures, it is excellent for those 32-50 degree days.

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-sized heater for a small garage or a small-sized heater for a large garage are both incorrect. The former would simply be a waste of energy, while the latter would give insufficient heat output. So, make sure you find a heater that is in accordance with your garage size. 


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

Price-to-Feature Ratio 

A better-performing heater with greater features may be a bit more expensive, but it will certainly offer comfort for a longer period with greater consistency and efficiency.

On the other hand, a cheaper heater may cause discomfort by not delivering expectations. However, this can be assessed better with the help of customer feedback 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 heaters function by warming up not only the air but also the objects present around them. This feature enables it to be energy-efficient as the room or garage where this heater is working, remains warm long after it has been turned off. It works by giving out electromagnetic radiation called infrared 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 easy on the budget for most people. They work by passing the air over a heating source and then circulating this heated air in the room. The most obvious disadvantage of such heaters is the noise they make, which is, however, being overcome with the advancing technology.

Electric Underfloor Heating System

Although electric underfloor heating systems have a pretty expensive installation, their long-term working expenses match with those of other types of heaters. They are very efficient and work by turning the whole 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 and requires expert service. Also, it is much more costly than an electric heater, which requires little to no installation efforts.


The maintenance of an electric heater does not require expert knowledge and experience, anyone can do it. But the same is not the case with a gas heater. Their annual maintenance is essential to ensure proper functioning for longer periods and avoid unpleasant accidents such as a gas leak.


The lifespan of an electric heater, which is about 20-30 years, is much longer compared to that of a gas heater, which is around 10-20 years.

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

The value of a heater cannot be determined based only upon its functioning. All other costs, such as installation and maintenance costs, matter a lot as well. However, based on the expenditure of running, a gas heater is cheaper than an electric heater. This is because natural gas is cheaper than electricity.


When it comes to space heaters, a heater can only heat your garage or shop to your desired temperature proportionally to the size and insulation level of the space. It is also important to take into account the outdoor temperature you will be using the space heater to offset.

All in all, these are all great options to accommodate different garage sizes and heating needs for all budgets.

People Also Ask

If you have read all the reviews for the best 120v garage heaters that are available on the market but are still unsure and have a few doubts in your mind, here are a few frequently asked questions by other customers that can clear those uncertainties. 

Where Should I Place My Garage Heater?

The placement of the garage heater depends on the type of heater you own. For a forced-air heater, you should opt for the coldest corner of your garage. If you do not have an idea of where that spot may be, place thermometers to measure the coolest area of the room. Also ensure that your heater is at least 7 feet above the floor and away from combustible items. 

How Many BTU Does it Take to Heat a 2-Car Garage?

If you own a forced-air heater, the rule would be 45,000 BTU to heat up a 2-2.5 car garage. In the case of an infrared heater, it would take about 30,000 BTU to heat a 2-2.5 car garage. 

Are Infrared Heaters Good for Garages?

Infrared heaters are a good option for small spaces, are easily installable, and run on natural gas. An infrared heater gives direct heat and warmth to the person or object and does not have high maintenance. It’s also less noisy and does not have a strong odor.

What is the Safest Heater For a Garage?

Because gas is highly flammable, you have to keep a constant check on it, which is why it’s one of the more dangerous kinds of heaters. However, some gas heaters come with safety sensors, so it’s more about the kind of safety features that come with the heater. However, infrared and forced-air heaters are usually safer. 

Will a 1500-watt Heater Heat a Garage?

The required power of a heater depends on the size of the room it has to be used in. A 1500-Watt heater can comfortably heat a space of up to 150 square feet. Depending on this fact, you can decide whether the heater you are purchasing will fulfill your needs or not.

Are Electric Garage Heaters Expensive to Run?

Electric garage heaters may often be considered expensive to run. However, that is not the actual case. When other factors, including maintenance, lifespan, and installation services, are kept in view, we can easily conclude that an electric heater has a much lower overall cost than most other types.
