Best Garage Heater Reviews (Top 8 List)

1. Best Electric Garage Heater: Fahrenheat FUH54

Fahrenheat FUH54 Electric Garage Heater

This is one of the best electric garage heaters you can choose if you have a medium-sized garage that fits 2-3 cars (about 500 square feet).

It’s a surprisingly small garage heater with almost industrial-strength power that it offers, which makes it perfect for individuals who don’t want to sacrifice too much of their precious garage space.

Even better, it has a relatively rare feature for such a unit, as it can also be mounted on a wall or ceiling with its emitted heat directed where you want it with an adjustable louver. This surely provides flexibility much-needed for manual work.

This FUH54 garage heater is definitely an excellent choice for your garage, workshop, or basement, with its max BTU of 25,000 and a wattage range from low to high of 2,500 to 5,000.

It’s an electric heater, so you won’t have to worry about connecting it to your gas installation or providing a gas cylinder.

It’s a small heating unit that, once mounted on a ceiling or wall, won’t disrupt your range of movement or routine. It’s quite heavy (25 lbs), but since it’s not a portable heater, it shouldn’t really concern you.

Thanks to its thermostat, you can adjust the power to your needs and preferences (from 45°F to 135°F).

However, you need to bear in mind that you can’t simply plug in this heater for it to work. As it has to be hardwired, you will need an electrician or another specialist who will be able to do this safely.

If you buy this garage heater through Amazon, though, you can additionally book installation upon delivery. This is another reason why we consider it to be the overall best space heater for garages.

Mr. Heater F274800 is incredibly safe, having the necessary safety features already built-in.

Thanks to the auto-shutoff system, the unit can turn itself off when it’s tipped over, the pilot light stops working, or the oxygen levels drop too low.

Besides, its shock-absorbing insulation provides durability and easy replacement of the ceramic burner tile.

You only need to remember not to place it too close to any flammable materials, as it still gets quite hot at times.

You can move it to different locations with a comfortable handle, which is also foldable so that the unit doesn’t take up unnecessary space.

Moreover, it’s possible to buy an additional connecting kit that will allow you to power this garage heater with a propane tank – it’s an excellent option for longer projects.

3. Best Propane Garage Heater: Mr. Heater MH60QFAV

Mr. Heater MH60QFAV Propane Garage Heater

It’s high-quality, designed and produced with great care, equipped with a high limit switch, thermoelectric safety valves, a 10-foot hose, and the propane tank regulator.

Its standard tank can last up to 14 hours if it’s on the low settings.

Both options offer much more power than a regular garage needs to be adequately heated, so it’s recommended not to use this heater in smaller areas, especially those with relatively low ceilings.

The Big Maxx garage heater has a powered exhaust system built in to enable horizontal and vertical venting. It has controls on its exterior if you want to be the thermostat (as it’s sold separately) or gas connections.

It originally comes as a natural gas garage heater but can easily be converted to run on propane liquid – all you need is a conversion kit that can also be provided by Mr. Heater.

Dr. Infrared Garage Heater DR-238 Electric Garage Heater

Not everyone has warmed to the idea of a device hanging from the ceiling, and when such a person doesn’t have too much space on the floor, the range of products to choose from significantly narrows.

Luckily, it’s not the end – Dr. Infrared Heater DR-238 is probably the best electric garage heater that was designed to be safely mounted on the wall.

The infrared heating system ensures fast but even warmth distribution both indoors and outdoors.

King KBP1230 Compact Electric Garage Heater

8. Best Kerosene Garage Heater: Mr. Heater Corporation MH70KFR

Mr. Heater Corporation MH70KFR Kerosene Garage Heater

With a tank capable of holding almost 3 gallons of fuel and producing 70,000 BTUs of heat, this garage heater can provide heat for about 6 hours straight.

Garage Heater Buying Guide

From the type of heater you prefer, to the space it can cover, when it comes to buying a garage heater, there are a few things you’ll need to consider. 

Below, we’ll take you through everything you need to know about garage heaters. This information can help you make a better-informed decision when it comes to purchasing one of these units, and ultimately, will help you find the best garage heater for your needs. 

Types of Garage Heaters

Gas Powered Garage Heaters

Propane or natural gas garage heaters don’t need electricity at all, which makes them more cost-effective as well as portable (unless there’s an issue with your installation and it’s a device connected to your natural gas line).

They run or gas or fuel, thanks to an extremely controlled flame located inside the unit that heats the air, which is later pushed into the room by a fan.

As discussed on our gas heater vs electric heater page, gas-powered garage heaters can heat up space quite quickly and maintain the temperature for extended periods without disruptions.

Whether it’s natural gas or propane, even the best space heater for garage of this type needs some regular maintenance to keep them working safely. Some people even opt to use this type of heater inside their homes.

If you want to see what’s available, check out our list of the best indoor propane heaters here.

Infrared or Radiant Garage Heaters

Most types of heaters produce heat by heating the air, while a radiant or infrared heater warms the object you direct it at – this may be your work surface, you, a wall, or floor.

They can heat it up quite fast directly but, logically, will need much more time to cover larger areas.

The top rated infrared heaters available are best for projects involving woods and other messy materials, as because they don’t have fans, they won’t stir up dust particles and other waste products.

Fan-Forced Garage Heaters

A fan-forced garage heater draws the air through a fan, warms it with its heating elements, and blows it back into the room.

A quality device of this type can efficiently warm up enclosed spaces of almost all sizes and is able to do it in a relatively short period of time.

However, because it blows the air around the room, this garage heater can make quite a mess if you work with wood or paint.

Garage Heater Power Sources


In general, electric garage heaters tend to be more expensive to maintain than other space heater types that run on fossil fuels such as natural gas.

Still, they are commonly chosen for both commercial and residential purposes, mostly because of their ease of use; apart from that, electric devices have become way more powerful recently, making them the best option for larger areas.

Moreover, the best electric garage heater units reviewed on this page are also safer to use, as they come with a variety of modern safety features.

Natural Gas

Natural gas heaters are incredibly cost-effective, especially if your house is already connected to a natural gas line.

Cost-effectiveness is especially important for heating larger areas and using the heater for longer periods of time. These units are usually quick to warm up and relatively stable in the long run; plus, they cool off quickly, so you don’t need to worry about leaving them suddenly.


Propane garage heaters are a popular alternative for those who can’t or won’t use an electric garage heater but aren’t connected to a gas line.

The main disadvantage is that they need to be refilled often if you run them for hours on end, and you should always think ahead to avoid a situation when you would be left without heat in the cold.

If you’re looking for a heater for recreational purposes (e.g. your patio) then this is good option to consider. Take a look at our best patio heaters list for the top recommendations.


A kerosene-powered garage heater is usually portable and reliable.

You can find two types of kerosene heaters: the radiant or convection one.

The former is best for smaller areas, as it uses a reflector or a fan to direct the heat at the desired object.

The latter, on the other hand, is designed for larger spaces, as it is cylindrical and can distribute heat evenly outwards and upwards.

What to Consider Before Buying a Garage Heater

How Big Is Your Space?

There’s really no need to look for the most powerful device if you only need a heater for your medium-sized garage.

On the contrary – if you buy a garage heater with too much power, you may create an excessively hot environment or even a safety threat.

Not to mention that it would simply be a waste of money. So, measure your space carefully to make the right decision.

Apart from the size of your garage, you also have to think about the shape of the space you need to heat, as logically, a square room will be much easier to heat up than a room of the same size with more walls and corners.

What Do You Want to Heat?

If you only want to warm yourself up when you work in your garage or workshop, it may be enough to buy a small, portable heater – it won’t cost you much even in the long run, and you will be 100% satisfied.

However, if you have a larger space or work with other people, you will have to consider where you will need the heat.

Can You Power It?

Consider available or desired power source to choose the most suitable solution.

For example, if you are connected to a gas line, a natural gas garage heater would be the best option, being the cheapest to maintain.

However, if you need a device to often provide you with heat for considerable periods of time, you probably wouldn’t like a propane garage heater that needs to be refilled way too often for such frequency of use.

Do You Need It to Be Portable?

If you need a device for different projects that you will carry out in various locations, then you definitely need to focus on finding a portable device.

The best portable garage heater units on the market can be powered by both propane and electric. So just choose the type prefer.

However, if you have a workshop and want to heat the whole space evenly, then a fixed garage heater would be the better choice. The best wall heaters reviewed on this page would be a better option in this situation.

How Much Can You Spend?

The average price of a garage heater is around $200, but you can find small units for as little as $25 and large and powerful ones up to $1,000, so be sure to choose according to your needs.

Is a garage heater worth it?

A garage heater is worth it if you use your garage for anything other than parking your car or using it as a storage space. If you spend time working in your garage, then heaters are worth it to keep the space from being too cold to spend time in.

Best Garage Heaters Safety Features

Best Garage Heater

No matter the power source of your garage heater, you should always pay attention to built-in safety features or those that can be added independently.

Different types of heaters may involve completely different potential threats, but some properties worth looking for in these devices include:

  • Guards and other safety nets are essential for you not to burn yourself by accident. You probably know better than to touch heaters, but accidents happen, and you should limit all the risks.
  • The overheat protection system makes sure that the device shuts itself off when any heating element gets too hot.
  • The tip-over protection system allows the heater to turn off in case it’s tipped over.

Using a Garage Heater – Safety Tips

The Electrical Safety Foundation International (EFSI) says to always “make sure your space heater has the label showing that it is listed by a recognized testing laboratory.” And before using the space heater, “read the manufacturer’s instructions and warning labels carefully.”

Additional tips on using a garage heater safely include:

  • Plug directly into an outlet. Make sure your outlet provides enough power for the amount recommended for your heater. Then, if it’s possible, plug it directly into an outlet, as all additional cords increase risks.
  • Don’t leave your garage heater running unattended. You never know what will happen, so it’s better to turn it off every time you leave, even if it’s for a relatively short period of time. Even the safest and the best garage heater can malfunction.
  • Make sure it’s stable. It will reduce the risk of the unit tipping over.
  • Always have a certified technician to repair it.
  • Don’t cover it. It’s not a regular radiator, so don’t put anything on a garage heater to dry off.
  • Keep an eye on children and pets, if you have any. 
  • Keep flammable materials away from your garage heater. Yes, you can find a large or small garage heater with special added protection, but whenever there’s heat involved, you’d better not take any risks.
