8 Garage Heaters That Actually Keep Your Garage Warm [2021 Review]

A garage is known to be a utility space of the home, and that’s true. They’re a safe place for the cars and storage, and they’re a sanctuary of sorts for craftsmen and craftswomen to get away from everyday distractions of the house in a space made for utility.

It’s not uncommon for a garage to lack central air, heat, and insulation. But there’s real value in temperature controlling this valuable space, especially in the winter, to keep equipment from freezing and make working in the garage comfortable.

Keep reading to learn how to choose the right garage heating solution for your space.

Things to consider before looking at heaters for your garage:

  • Consider your garage size. A 4 car garage will require a lot more power to heat than a one-car garage. Know the dimensions (or at least the number of square feet) of your garage.
  • Pay attention to specs. Each heater has its own list of specifications. Pay attention to those so you’re sure the one you choose meets your needs.
  • Know your goal. Some garage heaters are better suited for maximum heat in a short amount of time, others are more energy-efficient and suitable for long heating sessions. 
  • Choose your energy source. Whether you need an electrical or propane heater – or something else – will depend on your energy source. For example, choose an electric heater if you want to plug it into a wall, or a propane radiant heater if you want it to be self-reliant.

Heating a garage requires a lot of energy. With high ceilings, concrete floors, and less insulation, a garage isn’t just a matter of throwing in a small space heater and calling it a day. A small space heater would be lost to a space that size, even if it’s just a one-car garage.

What to Look for When Choosing a Garage Heater:

#1: Does the unit have good reviews?

It’s important when spending a few hundred dollars (which most garage heaters cost) to make sure others are satisfied with the product, because this is a great indication for how it will work for you. Take note of negative reviews and determine whether their issues apply to your situation and whether it’s worth the risk in your case.

#2: Is the unit energy efficient?

This is where you need to be very aware of your purpose in a heater. Are you interested in heating your garage during the winter, all winter? Or are you looking for something to keep you warm while you work on a project? Make sure if you’re trying to heat for long periods of time the unit you choose is cost efficient while running, or else you might end up with a huge power bill in a couple of months. Make sure your garage door is insulated for maximum heat efficiency.

#3: Can your space accommodate?

It would be terrible to have an expensive heating unit shipped to your house only to find that you don’t have the required setup for it. For example, a ceiling-mount propane-powered heater that requires 12 foot clearance wouldn’t make sense in a fully-finished garage without ventilation and a 10 foot ceiling. Likewise, if you have a large, open garage with no insulation, a portable space heater isn’t going to do much for you. Know what energy source is appropriate for your space and pay special attention to every specification of a heater before you purchase it.

#4: Does the unit provide enough power?

The most common customer complaint when it comes to garage heaters is that they don’t heat the garage effectively, and avoiding this problem is a matter of becoming an aware consumer. Know how much power you need to heat your space, and unless the unit you receive is defective you’ll achieve your goal. Here’s a helpful chart to reference:

Medium2-32500 watts
