Space Heater Buyer’s Guide: How to Choose the Best One

Before making your decision on the best space heater for your garage, there are a few things to think about.


The size of your space heater is crucial to your garage space. If you have a small garage, you don’t want a heater that takes up a lot of space. So, your best option is to look for something skinny, small, or wall-mounted. The less space your heater takes up, the less likely you are to knock it over or feel crowded.


You’ll find many different space heater types, with infrared and convection ones being the most common. Convection heaters usually use fans to heat and push air out. Infrared heaters act as heat lamps and radiate heat. Keep in mind that fan space heaters usually have more controls, allowing you more adjustability.

Heating Range

Garages are typically considered medium or large-sized rooms. So, you need to account for that when looking for a space heater. If you get one that has a small heating range, you won’t even feel the heat. That defeats the purpose of buying one. You’ll need to compare the square footage of your garage to the heating range of the space heater.

Safety Features

Your and your family’s safety should always be your top priority when picking the best space heater for your garage. The United States Fire Administration says that 3% of fires are from heating, with 41% being fatal! That’s why picking a space heater with automatic safety features is vital. Look for things like tipping protection, overheating protection, and automatic on/off features in case something goes wrong.

Why Should You Get A Space Heater for Your Garage?

If you find yourself questioning your space heater purchase, there are some great reasons to get one.

Your Temperature Sensitive Items Will Stay Safe

Most people use their garages as extra storage space. You may store furniture, books, old TVs, and much more in this space. But low temperatures can damage and break down many things. A space heater could keep your garage’s temperature regulated, preventing damage.

It Can Extend Your Car’s Lifespan

Cold temperatures can severely damage your car over time. The extreme temperature changes can affect the air levels in your tires, causing flats. Your battery may have issues, and your oil may thicken. Other things may happen as well, but these are just some of the possibilities.

Nobody wants to pay for expensive fixes or have to buy a new car without warning. Simply adding one of the best space heaters for garages can extend your car’s lifespan. It’ll keep your garage temperature higher than the outside air temperature and prevent the effects of the cold.

You can Work in Your Garage Without Freezing

Do you have a workshop in your garage? Or do you like to work on cars? It’s usually challenging to enjoy your time in the garage if you feel like you’re freezing. Chattering teeth and shivering won’t let you get much done. That’s where a space heater can help you and keep you comfortable while you work.

Frequently Asked Questions

Are space heaters safe in garages?

Space heaters are safe in garages as long as you follow the directions. Many of the best space heaters for garages have safety features to prevent danger. But it’s a good idea to only operate the heater in intervals instead of constantly. And you should only operate it when someone is home.

What size space heater do you need for a garage?

The size of the space heater doesn’t exactly matter. It’s the heating range that matters. You’ll usually want one that heats about 300 square feet. Most garages are around this size. This will ensure you get adequate heat throughout your entire garage.

Where is the best place to put a space heater in your garage?

You’ll usually want to put your heater in a corner of your garage. Ceiling or floor placement will depend on what type of heater you get. Mounted heaters will need to be off the floor and attached to a wall. Standing heaters can be on the floor or another flat surface. But always check the instruction manual to see what the manufacturer says.
