Heating Options to Keep Your Garage Warm

The good news is there are TONS of options if you are interested in ways to heat up your garage gym during the winter. The upcoming sections of this article breakdown these options, including the pros and cons of each option.

Electric Space Heaters

You’ve probably already seen electric space heaters in use. They look like little square boxes and they plug a power outlet and produce heat using electrical coils.

Most people use them in bathrooms that get too cold while others bring them to their office to warm up their workspace.

The great thing about electric space heaters is that they are pretty inexpensive and easy to use.

You only need to find an outlet and you’re good to go. Even the most expensive electric space heaters usually don’t cost more than $100.

The downside of electric space heaters is that even the most powerful space heaters may not have enough juice to heat the garage up when it gets really freezing cold.

Their effectiveness will largely depend on how cold it is outside (in the garage), how large the garage is, and how well insulated the garage is.

We generally recommend trying an electric space heater as your first option, since they’re inexpensive and only when it fails to meet your heating needs should you look for something more powerful.

Radiant Heaters

Radiant heaters are usually propane based, and you’ll find that they look a lot like the space heaters but work differently.

Radiant heaters use an actual flame that’s fueled by propane to create heat and disburse it with an onboard fan.

The main advantage of radiant heaters is that they are small-sized, also easy to use, and fairly inexpensive. However, not everyone will love using a propane tank.

Just like the electric space heaters, radiant heaters may not be sufficient to heat your cold garage fully to a comfortable temperature. You may be forced to get a more powerful heater.

Forced Air and Torpedo Heaters

Now we have officially crossed over to the big guns.

Torpedo heaters come in many different shapes and sizes, but they usually look like high-tech ray guns or telescopes.

They use an electrical outlet and a fuel source (mostly kerosene or propane) to generate heat and then circulate it with blasts of air.

Forced air heaters can pack a massive amount of heating power which will be enough to heat up your garage under any conditions.

If your budget allows it, we recommend that you also invest in a proper ventilation system in the garage to go with the torpedo heater.

Infrared Heaters

You may have seen one of those giant tower heaters commonly found on restaurant patios to keep them warm.

These are infrared heaters and they typically use electrical power and propane to create tons of heating power which can then be directed precisely at a specific area.

Infrared heaters are probably not ideal for your garage gym, especially since they are so powerful.

However, there are certain types of infrared heaters that can work for your garage, but we recommend getting an expert’s opinion before installing them.

Best Budget Garage Gym Heater: Pro Breeze 1500W Mini Ceramic Space Heater

Overview: If you’re looking for a simple, cheap solution, this inexpensive electric space heater will likely meet your needs.

Yes, it’s inexpensive, but that doesn’t mean that it’s low quality. It packs quite a punch for a 1500W heater; as it cranks out approximately 5,000 BTUs of heat.

The thing you’ll love most about this heater is its simplicity and compact size that allows you to move it around whenever you want.

Not to mention, you won’t have to deal with propane or kerosene. In my opinion, it is definitely worth giving it a try.

Best Mid-Range Garage Gym Heater: Mr. Heater Buddy Indoor-Safe Portable Propane Radiant Heater

Overview: If you’re looking for something a bit more powerful, but still portable like an electric space heater, this is another option to consider.

Mr. Heater Buddy can cook up between 4,000- 9,000 BTUs, which is stronger than most electrical space heaters.

However, it runs on a propane tank housed in the container’s side. Do not let the propane discourage you from buying this heater; yes, it can be a little intense, but the heater includes several safety features to keep you safe.

Pro Tip: Depending on the size of your garage, using two of these propane radiant heaters together in your garage, with one on either side of the workout area creates more even heating.


  • Compact-sized, lightweight and portable.
  • It is twice as powerful as most electric space heaters.
  • It has safety features that ensure it’s not a fire hazard.


  • You regularly need to refill the propane tanks.

Overview: If you’re looking for the best-in-class option, this is it. This forced air heater runs on a standard propane tank that cranks out 60,000 BTUs of heat for up to 11 hours.

This immense power is enough to heat up a 1,500 sq foot enclosed area, which is much more than most people need for their garage gym.

In fact, unless the other heaters work for your gym, you should not use this heater, especially in small gyms.


  • It uses propane which is easier to work with and cleaner than kerosene.
  • It is strong enough for any heating needs you have at your garage gym.
  • It doesn’t require a hook-up to the gas line.

Additional Tips for Cold Winter Workouts

The following tips are some things you should keep in mind when working out in your garage during the cold season.

If you have a powerful torpedo heater, you may not need these tips but they sure do go a long way in making things warmer:

a) Wear Layers of Clothing

The winter is not the time to work out in your cute yoga pants that show off your great body. You need to dress for the occasion, and this means wearing warm but light clothing.

You don’t have to wear warm clothing the entire time. Just keep it on until your body warms up and you no longer feel cold.

b) Warm-Up Properly

A warm-up is a vital part of your exercise routine, particularly during the winter.

Warming-up promotes proper blood flow throughout the body which distributes heat all over making you feel warmer. A good warm-up prevents injuries and also helps you to perform better in your workout.

c) Store Your Barbells and Other Metallic Equipment Inside

Your heater may create the perfect warm environment for you to exercise in, but your barbells and other metal gym equipment will be freezing if you leave them in the cold garage the entire night.

There’s nothing worse than grabbing a barbell only to realize that it’s absolutely frigid. Obviously, you won’t be able to move everything inside, but the barbells are a good place to start.

Some Final Considerations

Please don’t use the cold winter as an excuse to stop working out in your garage gym. Grab a heater ASAP and turn your garage gym into a warm place that you’ll love to work out in.

You can start with an inexpensive electric space heater, but if your budget allows it, we recommend using a powerful forced air heater to solve your heating problems once and for all.
