Dr Infrared  Portable Space Heater

Key Features:

  • Dual heating technology
  • Up to 12 hour
  • Electronic thermostat

The Dr. Infrared Heater is not only a good heater for a garage gym but has helped thousands of people in freezing garages over the past few years.

It comes with a remote control, unlike most other space heaters you’ll find.

The bottom has casters, allowing you to move it around with ease to anywhere in your garage gym.

Wheels are important because it works with infrared technology and doesn’t heat the air in between you and the heater. Allowing the heater to get closer to you will help you stay warm.

The thermostat control has a range from 50-85 degrees, giving you the safety features you’ll need.

This heater is a great option if you have kids or pets running around in your garage.

It also has 12-hour automatic shut-off timer if you forget to turn it off while you’re away.

While this unit won’t be able to output as much heat as a propane heater, it’s still going to get the job done in smaller garage gyms of around 150 square feet or larger insulated garages.

If you live in a really cold climate and your garage is large as well as uninsulated, you’ll want to go with a much stronger electric or fuel-based heater for your garage.

Overall though, this is the best space heater for a garage gym on the market and should do you well as long as you’re aware of how much it can actually heat.

  • Control at a distance
  • Soothingly quiet
  • Safe to the touch
  • Menu and buttons are clunky
  • Tiny bit of chemical smell

Dr Infrared Outdoor Heater

Key Features:

  • 3 heating modes
  • Overheat protection

If you’re low on space in your garage gym, a mountable infrared heater is another great choice.

This unit can be mounted not only on the wall, but on a tripod so you can get the heat as close to you as you need.

I love that you also have the option to upgrade to a 240v version which can output 3000W. This is perfect for a large garage gym of around 400 square feet.

Depending on how well your garage is insulated, you may only need one, but prepare to purchase two or three if you have a large garage gym.

You can choose between the 3 power settings of 900,1200 or 1500W depending on how hot you want it to go.

I like that you can also take it with you and double it as a patio heater. You may also want to consider table top heaters for your patio.

It also comes with a remote, which is rare for electric space heaters, giving you control from anywhere in your garage gym.

To top it all off, it’s weatherproof which will prevent any damage if there are any leaks in your garage.

Some downsides it that the instructions it comes with are lacking and the cord is short, and it’s not the safest thing in the world to use a heater like this with an extension cable.

The biggest benefit of this type of space heater is the ability to mount it in 3 different ways.

You can even opt to use it on a tri-pod which would make it super easy to move around. Don’t forget that you can hang these from the ceiling as well!

Overall though, for the price, it comes with a remote and can be installed in many different orientations.

Considering the price, the Dr Infrared Heater is hard to beat. The only downside is that it won’t be mobile and must be installed somehow.

If you’re low on space but still want to be hot this winter in your garage gym, it’s hard to go wrong with this option.

This space heater uses forced air to spread the heat all around your garage gym.

It comes with a 12-hour timer as well as 24-hour automatic shut off if you forget that you left it on.

The cord is 6 feet long which makes it great if you want to bring it near you.

One downside of this unit is that it doesn’t have wheels so it will likely get hot and be difficult to move around when in use.

The temperature gauge on the top isn’t quite as accurate as we’d like either.

You do however get the ability to move this unit inside as its fairly compact, so you can get more usage out of it without having to lug around a huge heater.

Overall though, for the price, it comes with a remote and is going to do the same amount of heat as any other 1500W heater on this list.

With it’s 2 quiet settings, you’ll be able to get your workout in without any distractions.

You can also utilize the adjustable thermostat to get the temperature right to your specifications.

As a garage heater, it’s important that the hot air is moved around your garage with a fan. Otherwise, you may have an uneven distribution of hot air inside of your garage gym.

You’ll be able to use the included remote, which is going to be a lifesaver.

The built in safety features like overheating protection and tip-over protection make it safe to use around pets and children.

Once you’re done in the garage, you can take this with you inside and stay warm all year long.

I love that this heater also comes with a 3 year warranty should anything go wrong.

Unfortunately, the handle on the top is a bit clunky and not easy to carry. Some reviewers of this product also mentioned some smell when using it.

Even considering the downsides, this heater is going to be great for smaller garage gyms and you won’t need to spend a ton of money on it either.

With two quiet settings, you’ll be able to focus on your gym workout without any issue.

It’s hard to find a 120v heater with an adjustable thermostat, and with this unit you get control that you’re after.

Best Propane Space Heater for Garage Gym

Mr. Heater Corporation F299730 Heater

Key Features:

  • Heats up to 750 square feet
  • Electronic ignition
  • Built-in thermostat

If you have a larger garage gym or an uninsulated garage, you’ll need far more heat power than you think.

A 1500W space heater is only capable of heating around 150 square feet (in the best circumstances).

This 30,000 BTU heater is going to be great for garages up to 750 square feet.

You can choose to use this as a wall-mounted heater or use the included legs and keep it nearby.

Like other forced air heaters, this one utilizes a fan to get the heat in every inch of your garage.

It comes with wire guard protects to prevent anyone from touching the burner and it has oxygen depletion sensors as well as tip over protection.

The downside of this unit is that you will need to use a propane tank and even though it’s considered ventless, you should always use proper ventilation when using any fuel based heater.

That means you may need to keep the garage door open a little bit, which may seem counterintuitive, but it’s better to be safe than sorry.

Another downside is that if you have children around, you’ll need to be extra careful as it does use fire to heat, rather than electricity.

I think that for larger gyms or uninsulated spaces, this is going to be better than most electric heaters on the market.

If you’re setup already to use a propane heater, then this option is going to be great.

Larger garage gyms are going to require more heat output, and 120v heaters (or regular space heaters) are not going to cut it at 1500W.

Most people end up being disappointed when they realize that their tiny heater won’t be able to heat their large garage gym.

Don’t make that mistake and buy the right sized heater for your gym this winter.

  • No outdoor venting required
  • Low oxygen safety shut-off
  • Can be wall mounted or freestanding
  • Some smell
  • Little flimsy for floor use

Best 240v Space Heater for Garage Gym

Comfort Zone Ceiling Mount Heater

  • Adjustable mounting bracket

Another option is to go with a 240v heater for your garage.

You won’t have to worry about using space on your garage floor, simply hang up this heater in a corner.

The durable steel construction ensures this heater lasts a lifetime and can withstand garages with poor insulation.

You can choose to maneuver the louvers however you’d like, getting the hot air right where you need it.

The thermostat knob also gives you full control to get the heat to the perfect temperature.

One upside of the knob is that it can turn off the heater, which isn’t true for all 240v heaters. Some of them won’t shut off unless they’re disconnected or hooked up to an external thermostat.

With the safety features like overheat protection and power indicator light, this garage gym heater was built with safety in mind.

The biggest downside of this 240v heater is that you’ll need to hardwire it to your electrical system. This will drive up the cost if you need to hire a professional.

Overall though, if you know how to hardwire this heater yourself or have a friend that can do it, it’s going to be easily able to heat even a larger garage gym without any issue.

While it isn’t the most aesthetic heater on this list, it does allow for much more heat output with its 5000 available watts. That’s enough for a 500 square foot space!

Consider that most 120v heaters can only heat 150 square feet, the extra investment will be well worth it once you’re finally able to workout in the dead of winter.

  • Built-in overheat sensor
  • Power indicator light
  • Targeted heating with direct airflow 
  • Need to balance the fan
  • Noisy

Best Space Heater for Large Garage Gym

Mr. Heater Portable Propane Heater

  • Runs on a 20 lb. propane tank
  • Continuous ignition

Have a large garage gym? This propane heater is suitable for up to 2000 square feet.

You can choose to use it on a 30,000 BTU setting, which will be enough for 1000 square feet.

You’ll get around 14 hours of run time on a 20lb tank on the 30,000 BTU setting.

It’s easy to use with the ignition system and has a handle on the top making it a portable heater.

The biggest downside with this heater is that you will need to ventilate your garage.

This space heater will also be a bit louder than space heaters as it’s using forced air to move the heat around your garage.

The biggest benefit though is that your garage WILL get warm with this bad boy.

You will however need to be mindful of how much propane you’re using as it can add up, fast.

If you don’t mind cracking your garage door a little bit and bringing in some cold air for ventilation, you won’t have any problem staying warm with this garage heater this winter.

This heater is rated for up to 1500 square feet, and it’s important that you don’t put this heater in a small garage gym.

An oversized heater can cause problems, and will likely cycle constantly which will be a waste of resources.

If you do have a larger space and need extra heat and have ventilation this is a perfect fit.

  • High temperature limit switch
  • Quick assembly
  • 10′ hose and regulator included
  • Can be noisy
  • Some smell

Final Thoughts

If your garage is on the smaller side, then the Dr Infrared Heater Portable Space Heater is going to be a great tool to keep you warm while you workout this winter.

For larger gyms, you should need a more powerful unit like the Mr. Heater Corporation F299730.

Always be mindful if you’re using fuel based heaters in your garage, as it can be dangerous if you don’t use the proper ventilation.

You can also look into 120v garage heaters or torpedo heaters as well as propane wall heaters to consider the best options for your garage gym.
