9 Best Heaters For Garage Gym Of 2025! (Tested & Ranked!)

Garage gyms are extremely handy and convenient but can get cold at times. I discovered that with a convenient and intuitive interface, the Dr Infrared Space Heater makes the perfect warming addition.

The first and most impressive thing I must mention about the Dr Infrared heater is the three-year warranty.

This warranty alone is one of the main reasons Dr Infrared comes in as the top pick.

This tells you that the company believes in what they are selling and is willing to stand behind it.

Dr Infrared also offers big heating at 1500 watts. Heating like the sun, heating up objects rather than warming the air offers the utmost efficiency.

In fact, this heater uses 100 percent of the heat it produces.

The compact and portable design with rolling wheels and 72-inch, 120-volt power cord offer complete flexibility and ease of installation.

Plug the heat in, set the temp, and let it go to work warming. There is a remote for quick and convenient controlling as well as programmable heating timers.

The KEY TEK Wall-Mounted Heater might not actually be the cheapest buy on the list, but it is certainly the best buy for the money.

One of the reasons for this is its instantaneous heat. A lot of electric heaters on the market claim they can deliver instant heat, but there aren’t many that deliver on those promising.

The KEY TEK Wall-Mounted Heater is one. In addition to the quick heat, this heater is absolutely beautiful with a futuristic tube design.

You don’t have to worry about wheeling it around the floor or storing it in the summer either.

The wall-mounted design allows you to place the heater up high out of the way of a nearby wall.

Although the KEY TEK was designed for patios, it can be used safely indoors.

In fact, the outdoor weather-resistant design only adds to the overall durability of this impressively made heater.

Installation and operation couldn’t be any easier with the included mounting hardware and ability to rotate the heater a full 90 degrees once it’s installed.

Huge power with extreme portability is what the Sunnydaze Heater should be noted for. Unfortunately, the heater will need to be connected to a 20-pound propane tank.

However, it will be able to offer 125,000 BTUs of heat. Due to the fact that it is heated with propane, it will need to be used in a well-ventilated area.

That said, this heater will go right to work when fired up.

It won’t be long before the entire space is comfy and warm, giving you the ability to work out in your garage in the most extreme of conditions.

Do not be fooled by the big power. The Sunnydaze Heater does an excellent job of offering convenience and portability.

With the built-in handle and lightweight design of only 14 pounds, you can easily maneuver the propane heater to wherever you want.

This also makes it convenient to store when winter is over. The regulator is included so there is no need to purchase that additionally.

Add that with the 10-foot propane hose and 4.5-inch power cord and you won’t have a problem getting this bad boy installed and up and running in a matter of minutes.

With 5000 watts of power, you’ll be able to heat a 500 square foot room quickly and efficiently. The built-in thermostat offers the utmost control.

Some downsides to the heater are that it’ll need to be wired to 240-volts and there is no remote control.

There is a built-in thermostat, but remote operations are non-existent. Other than that, you cannot be the huge power this convenient little package offers.

The included mounting hardware only adds to the convenience of the device.

What Has to Be Considered When Picking a Heater for a Garage Gym?

Going into a scenario where you are buying a heater for your home gym helps narrow the playing field a bit.

Unfortunately, I found that it doesn’t narrow the playing field all that much.

Even with this information, there are still loads of essential considerations.

The price and heating area are no doubt the two most important, so once you know those, you’ll have narrowed your field even more.

With the heating technologies available in today’s market, you’ll still have a lot to factor in.

Small or space heaters are no longer just manually controlled. As you can see from above, there are a variety of remote controlling options.

If this is important to you factor it into the equation, although it’ll certainly raise the price.

There are also variable fan speeds to consider, the design, weight, warranty, and type of heating you want.

I found it essential to understand the heat that specific heaters produce.

For instance, infrared and radiant heaters offer a heating technology similar to the sun.

Some models offer forced convection heating. It honestly comes down to personal preference.

All the options above are no doubt impressive and most come from reputable heating manufacturers.

However, if you want to venture out on your own, you can pick some of the most important features from above and apply those to your search parameters.

Going with a reputable name is always a good option.
