Buyer’s Guide

What is a Garage Heater?

A garage heater helps you create a comfortable space as the winter months creep in. You can power a 120v garage heater using natural gas or electricity. They come in two different categories: forced-air and infrared. Read on to find out more about each type.

Forced-Air Heater

Wikipedia defines forced-air heating as a system where heaters use air as the heat transfer medium. What happens is that a heating pump is used to warm up the air, and then a fan blows it across the room. These types of heaters are ideal for large spaces, and they can heat up a garage quickly.

Moreover, they are less expensive than other types of garage heaters. If you want to save up on money for a garage heater that you only need for a few months, forced-air heaters are a great choice.

On the other-hand, forced-air heaters can be loud and noisy. If you require a quiet space, this can be a problem. They are hotter near the ceiling and colder near the floor. That’s another reason why people may not prefer fan-forced heaters. This isn’t noticeable with tiny garages, but if you have a garage with high-ceilings, it’ll be a problem.

Steer clear from buying forced-air heaters if you use your garage for hobbies like woodwork or painting. They will blow air all over the place, so you’ll get dust over everything.

Infrared Heater

Infrared garage heaters use radiated heat. They work slower than the forced-air heaters, but they can help warm up the air near the ceiling.

Unlike a forced-air heater, an infrared heater is noiseless. It has a shorter recovery time. Moreover, infrared heaters can warm up the air near the floor.

Another great thing about the infrared heater is the low cost. Some people complain that it is pricier than other types. If you look at the long-term operating cost, you will be saving more money.

Remember to find the perfect spot for infrared garage heaters. Avoid placing them near any objects and maintain a safe distance of at least 3 feet.  

Features to Consider

Since 120-volt garage heaters come in a wide array of styles and options, you must make choices wisely. We recommend that you prioritize the following factors:

  1. Wattage/BTU

You’ll find that 120-volt heaters come in several different sizes. Most garage heaters are rated at 1,500 watts, but you’ll also come across models rated at 1,200 watts, 2,500 watts, and 4,000 watts. Some heaters are also rated in British Thermal Units (BTU) and one (1) watt = 3.41 BTU. The higher the wattage or BTU value, the more heat the model delivers.

  1. Size of the garage

How much of the garage space are you looking to heat? Is it 250 square feet, 500 square feet, or more? A standard 120-volt garage heater rated at 1,500 watts (5,200 BTU) is suitable for spaces between 400 and 600 square feet. The coverage depends on other factors, such as insulation or ceiling height. The good news is that garage heaters display the recommended coverage area on the label to help you make the ideal choice.

  1. Ease of installation

You get to choose from fixed (wall or ceiling mounted) and portable installation options. Fixed garage heaters are difficult to install. Moreover, they’re hardwired, so you might need to hire a professional, which is an additional cost. If you aren’t prepared to spend your time and money on installation, a portable model would be a better choice.

  1. Convenience controls

Features such as remote control and digital displays and make it extremely convenient to control the temperature in the garage. An adjustable thermostat is another feature to consider. Also, check if the unit has a timer function. Timers let you program the heating for the desired time. Once the set period ends, the heater goes off automatically.

  1. Safety features

Make sure that the heater is built for safe use. One of the hallmarks of a safe garage heater is listing or certification by a recognized organization such as the UL, ETL, or CSA. Aside from certifications, check for important safety features such as overheating protection, anti-tip-protection, and a cool-to-touch exterior.

Garage Heater Gas vs. Electric – Comparison Overview

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


The installation of a gas heater can be a time-consuming process and requires professional service. Also, it is costlier than an electric heater, which requires no installation efforts.


The maintenance and upkeep of an electric heater do not require professional knowledge and experience. But gas heaters require annual maintenance to ensure proper functioning for extended periods. It’s essential to avoid unpleasant incidents such as a gas leak.


The lifespan of an electric heater is about 20-30 years, and it is much longer than a gas heater, which is about 10-20 years.

Reasons for Getting a Garage Heater

If you live in a place with sub-zero temperatures during winter, an electric garage heater is a must-have. The battery of your cannot withstand that temperature. Without a garage heater, it will have trouble starting every morning. If you store home-appliances inside your garage, the cold may cause some damage to them.

Another reason to buy a garage heater is to prevent pipes from freezing. Moreover, mold and mildew can grow in your garage due to damp settings. It can be dangerous to the health of the people living inside your home. But if you heat up your garage properly, there will be no danger of mold and mildew in the garage.

Lastly, if you are working on a project inside the garage, there will be no need to stop your work during the cold months. An electric garage heater will make the space warm and cozy. Some people use garages to work on interesting hobbies, like making a painting. When it gets too cold, it’ll become difficult to continue with your hobbies. But with a garage heater, you can make the space comfortable during winters.

What Electric Garage Size Heater Should I Get?

There are different types of garage heaters, and you need to choose the right one for your garage. There are several factors affecting your decision. One of the most critical considerations is the size of your garage.

When talking about size, you should consider the whole area, including the height of the ceiling. If you have a small garage, like 30×30 feet, a 120v garage heater is perfect for making the space warm. If you want to heat up a larger space, you may want to buy two 120v heaters. For commercial spaces, it’s best to invest in 220v garage heaters.

Moreover, you can use simple ways to estimate the exact size that you will need. Most people decide on 10 watts per square foot of garage space. So if your garage has 300 square feet of space, you will require 3000 watts to heat it. This method is for electric heaters.

If you are using a gas garage heater, you’ll have to try different units of measurement. Instead of watts, you will be calculating BTUs. You can do a simple calculation and multiply the wattage by 3.41.

What Type of Garage Heater Should I Get?

Now that you know the size of the garage heater you need, the next step is to decide the type of electric or gas heater you want to buy. You can choose a free-standing heater or a ceiling-mounted heater instead.

Both options have their advantages and disadvantages. A free-standing garage heater is great because it offers portability. If you have a bigger space and want specific areas to have heat, you can just move the heater there. You can even move a free-standing heater to other areas in the house, like your patio.

The downside of portable heaters is that they can take up space. If you are want to place a free-standing unit in a small area, there is a risk of bumping into the heater while moving around. Some models don’t have any safety features, making this even more dangerous. However, you can find some heaters with an automatic shut-off feature.

A ceiling-mounted garage heater is ideal for saving space as they don’t take up floor space. It’s perfect for garages that are small or have plenty of stuff in them.

The problem with the ceiling-mounted garage heaters is that you can’t move them to another location. Once you attach it to your wall or ceiling, it’ll stay there. Therefore, you need to choose the right size for the garage.

Electric Garage Heater Maintenance

After you buy an electric Heater, the next step is keeping it working optimally for a long time. To ensure the longevity of any device, maintenance is imperative. Follow these tips to keep your heater in top shape.


Dust particles tend to settle on heaters during use. Therefore, you should dust it once a week and remove any foreign particles.

Remove grime

Pour a dishwashing liquid on a damp microfiber towel and wipe away grime.


For heaters with vents or grilles, vacuuming regularly will help clear airflow. The same applies to models with fans.

Wipe heat reflectors

Electric heaters use a reflecting surface to reflect heat. This surface can often become dusty. Unscrew the grill protecting the reflector plate, and use a dry towel to dust off the plate.

Remove rust

The reflector surface can catch rust if not dusted regularly. Use a rust remover spray or scrub the surface to remove the rust.

Remember to turn off the electric heater and allow it to cool down before you start cleaning it.
