Whether you’re tinkering around with tools or getting under a car or truck to take care of serious repair work, a garage heater can help make sure that you’re comfortable if you’re working during the coldest months. Piling on extra layers of clothing such as hats and gloves could restrict your movements or get in the way of your visibility, but a garage heater can ensure that you’re warm enough to work.

With so many different kinds of garage heaters, finding the one that’s right for you requires a good deal of research, but we’ve made it easier for you by compiling customer satisfaction ratings and expert opinions to determine the best garage heaters across a variety of categories. Read on for our recommendations, which we’ll update periodically, as well as tips on how to determine which garage heating solution may best suit your needs.

Electric garage heaters are typically seen as not being as powerful as their fuel-burning counterparts, and while it’s true that a gas heater or liquid fuel can provide stronger heat output, the right electric heater can meet your warming needs as well. Case in point: the Fahrenheat FUH54.

The Fahrenheat FUH54 offers up to 5,000 watts of power, with an adjustable thermostat that goes from 45 degrees to 135 degrees Fahrenheit. The electric garage heater needs to be hardwired (rather than plugged in), which means it requires an experienced electrician to be properly installed, but on the plus side, the relatively small size of this heat unit means it can be installed and mounted in a variety of locations.

If you need an even more powerful shop heater, the FUH724 model provides up to 7,500 watts of heating power, while the FUH1024T heating unit provides up to 10,000. Still, for an average-size garage, the FUH54 should make for a sufficient and reliable heating solution.

Mr. Heater

Like every kind of garage space heater, propane units come with their own safety concerns — in this case, carbon monoxide is generated by the burning of the fuel and must be properly vented outside. When it is, though, propane units are effective and useful heating solutions, and the best one on the market is the Mr. Heater MH60QFAV.

The MH60QFAV is what’s known as a “torpedo heater,” named for its shape. This propane forced air heater generates heat that spreads out from the open end and, at a maximum power output of 60,000 BTUs, can warm a room of up to 1,500 square feet. It’s also a portable propane heater, so as long as you have a propane tank (and an outlet to power the unit itself), you can use this portable heater wherever you please.

The gas garage heater unit is a great value for the amount of heat it generates, and consumers have noticed — it’s the number-four space heater on Amazon. Even more impressively, customers who have purchased it seem to be very happy with their decision, as it currently has 4.6 stars out of 5, based on more than 500 reviews.

Mr. Heater

Mr. Heater is one of the leading names in heating solutions, and for an example of just how heavy-duty their products can get, one needn’t look further than the MHU80 — also known as the “Big Maxx.” Not only is it the best choice when it comes to natural gas heaters, it’s also our top pick for heating large garages.

The Big Maxx natural gas heater generates 80,000 BTUs of heat per hour, making it a great option for heating garages of up to 2,000 square feet. This forced air garage heater works via a fan that pulls in cool air, and then heats it before expelling it, and while it is on the larger side — it weighs more than 85 pounds — all that power has to come from somewhere. Plus, once this natural gas heater is properly mounted, the weight won’t be an issue.

Please note that the Big Maxx air heater needs access to an electrical outlet for the fan and a gas source to enable heating. The kit for hooking the unit up to a gas source is not included with the heater, but you can purchase it for $25. If you choose not to purchase the hookup kit, you’ll have to provide your own natural gas connection or use the heater with a liquid propane tank.

Dr. Infrared

If you have a smaller garage or one that’s well insulated opposed to an uninsulated garage, you won’t need the pure heating power that would otherwise be required. Something a little more modest — and a little less expensive — can get the job done for you, and the Dr. Infrared Portable Space Heater is an ideal choice in those situations.

The 1,500-watt infrared garage heater can be set for temperatures ranging from 50 degrees to 85 degrees Fahrenheit, and has a programmable timer and thermostat that allows users to regulate their surroundings to a desired temperature for up to 12 hours in advance. This portable heater also has built-in safety features, such as overheat protection and an automatic shutoff switch in the event the infrared heater is knocked over.

As the name suggests, the Dr. Infrared Portable Space Heater is a truly portable garage heater, weighing only 19 pounds and drawing electric power from a wall outlet. Anytime you need a quick heating solution — whether it’s in your garage or in your house — the Dr. Infrared Portable Space Heater can get the job done.

Mr. Heater

Portable heater units are typically smaller and less expensive than their stationary counterparts, and the Mr. Heater MH9BX — also known as the “Buddy” — is no exception. What makes it the gold standard for convenience, though, is that it runs on liquid propane, and even holds a small tank. That means you can use it anywhere, indoors or outdoors.

The Buddy also has built-in safety features. Not only does it shut off when tipped over, but it has an oxygen depletion sensor that shuts down the unit if it detects a problem with gas (this should not be taken as a substitute for proper ventilation, though). While the heater does have a relatively low power level, it has the heating capacity for 225 square feet that can service a small garage, or simply keep you warm if it’s placed nearby.

The Buddy’s price, ease of use and reliability have made it incredibly popular. It’s currently the top-selling heater on Amazon, and satisfied customers are raving about it. It has 4.7 stars out of 5 on the site, based on nearly 7,000 ratings.


If you have a large garage to heat — a multi-car garage/workstation, for instance — you’ll need a powerful gas garage heater, and these usually cost more. While there are bargains to be found at any price point, if you’ve decided that you’ll spend anything for the right heater, it’s worth considering the Modine HD45AS0111 — one of the models in the company’s “Hot Dawg” product line.

This particular model runs a hefty $750, but it’s effective and versatile. User reviews on Amazon report how quickly it heats up a room, and while it is designed to be a natural gas heater, it can be converted to be a propane garage heater if you need or prefer it that way. For proper ventilation, it features an exhaust pipe that needs to be vented outside to expel harmful gases.

Finally, it’s worth mentioning that this is just one of the air heater products in the Hot Dawg line, and your needs may vary based on space and price. In all, there are six heaters in the line, ranging in power from 30,000 to 125,000 BTUs of heat output.


If you want a quick and easy heating solution at an incredibly low price for open garages, odds are you won’t be able to do better than the Remington REM-16-TTC-O. A portable propane-powered unit that only costs $45, it generates an amazing 16,000 BTUs.

The REM-16-TTC-O doesn’t require any electricity to run — simply hook it up to the top of your propane tank, and it will put out the heat you need. It has some safety features — such as a shut-off valve and a tip-over switch — but it also gets extremely hot while operating, so it’s important to make sure not to touch anywhere near the heating element while it’s in use.


Kerosene heaters have similar risks to propane-gas garage heaters — namely, they expel toxic fumes and require a ventilation solution. That said, if you can provide adequate ventilation, these heaters can be convenient and affordable alternatives to electric or natural gas garage heater units.

The Sengoku KeroHeat Portable Convection Kerosene Heater is a 23,500-BTU heater that can warm a room of up to 900 square feet. It’s freestanding, so there’s no installation required, and it’s battery operated, so it doesn’t need to be connected to a power cord and then a wall outlet. Simply fill it with kerosene, turn it on and it will be ready to generate 12 hours’ worth of heat.

This kerosene heater is also designed to be as easy and safe to use as possible. It has one-touch shutoff capabilities, as well as an automatic shutoff switch that activates if the workshop heater is knocked over. At only $167, the Sengoku KeroHeat air heater offers a lot of convenience at a very reasonable price.
