Best Natural Gas & Propane Garage Heater

Gas heaters would be a good choice if you have a larger garage or work space. Electric heaters won’t produce enough heat to warm larger garages. Natural gas garage heaters, or if natural gas utility is not available, propane gas heaters can heat your whole garage.

Many natural gas heaters offer a propane conversion kit. Either way, you’ll likely need professional installation to run the natural gas lines (or propane), vent for carbon monoxide, and install a propane tank.

Natural gas and propane heaters can heat two-car garages and three-car garages with one ceiling or wall mount heater. Most gas or propane heating systems will heat 2000SF or more, so even a huge garage can be warm.

Types of Garage Heaters

Three main types of electric heaters are considered the best for use in your garage. Each type ranges in size and functionality to produce a comfortable environment in your garage. Let us go over all the heaters that fall under these categories:

infrared heater

Infrared Heaters

Radiant or quartz heaters are other names for infrared garage heaters. They produce radiant infrared heat, which you can use in small and large garage spaces. These small heaters pack a punch.

Instead of fan-forced or ceramic electric garage heaters, they start running as soon as you turn them on and have a very high heat output.

On the other hand, the heat generated by infrared heaters does not warm the air inside the garage. In other words, infrared heating warms the actual structures in which the infrared waves come into contact, such as with humans or cars. This means the ambient air temperature has not increased when the heating is running.

When the heater has been turned off, the temperature of the things and people in the garage drops rapidly. This also implies that the more things and people you have in your garage, the less powerful the infrared heater will be because the beams will be scattered around the space due to the objects and people.

ceramic heater

Ceramic Heaters

Ceramic electric garage heaters work in the same way as fan-forced heaters.

Still, these radiators have one significant difference. They use a ceramic heating element instead of the metal part used in fan-forced heaters. Because of the material difference, ceramic heaters are much more efficient than a fan-forced heater at heating an expansive room.

Ceramic heaters are a decent choice for more significant areas where you increase the indoor air temperature rather than only heating physical artifacts, as in an infrared heater. On the other hand, Ceramic garage heaters can take some time to heat up until the fan can begin blowing warm air.

electric fan heater

Fan-forced Heater

Fan-forced heaters heat the air surrounding them using an electric heating device inside the heater. A fan in the heater’s back drives this hot air out into the garage or workshop, warming the surrounding air and raising the temperature in the building.

This electric heater takes longer to warm up and is not as efficient as a ceramic heater. So, a fan-forced heater would suffice if you have a smaller workshop and do not mind waiting a little longer for heat. Otherwise, an infrared or ceramic electric garage heater may be better.

What to Look for When Choosing the Best Electric Garage Heater?

Before choosing an electric garage heater for your garage or workspace, take a few minutes to educate yourself on the most crucial shopping considerations to keep in mind.

radiator heater

1. Adjustable Thermostat 

If you want an electric garage heater that will control the room’s ambient temperature and switch on when it is too cold and off when it is too hot, you will need one with a built-in adjustable thermostat. 

This function allows you to set the optimum temperature for the garage, and the heater will begin heating automatically until the ambient air in the room exceeds that temperature.

This role is perfect in colder climates where 24-hour heating is needed, as the auto on and off functionality can keep your garage at the proper temperature without wasting excessive electricity.

large open garage space

2. Garage Size

When choosing an electric garage heater, the size of your garage is a significant factor to remember. If you purchase an insufficiently efficient heater for the room you want to heat, it will leave you working in the cold and the money you wasted on the faulty heater.

A reasonable rule of thumb to remember when selecting an appropriate garage heater is that for every 10 watts of production, you can heat 1 square foot of room. For example, a 1500-watt electric garage heater can heat a 150-square-foot garage or store.

Also, consider how much physical space you have. If you only use a third of your garage and the remainder is used for your car or storage, you might be able to get a smaller heater that will provide enough space for you while not wasting electricity by heating the rest of the unused area.

wall mounted garage heater

3. Portable or Mounted

Electric garage heaters are classified into two groups based on their installation: mounted and portable.

Mounted Electric Garage Heaters 

It is possible to install it on the wall or the ceiling. They can either be hardwired into the building’s electrical grid for a more efficient heat output or plugged into a standard power socket, a less complex form of installed heater to install than the hardwired kind.

If you want a semi-permanent heater that you only have to set up once, mounted heaters are a perfect choice. These larger units can be too strong for a small room if you do not have a huge garage or studio.

Portable Electric Garage Heaters 

These heaters can be placed on the floor or on a table. Portable electric garage heaters can also be moved whenever and wherever you choose to get the room’s best heat.

These heaters do not need much assembly or configuration and usually require an available outlet to start working right away. These heaters take up room on the floor and tables, and their cord can be a tripping threat.

garage heater maintenance

4. Maintenance

Any heating or cooling appliance will take some maintenance to function correctly over time, and an electric garage heater is no exception.

Lightweight heaters are less costly than heavier-duty models, but they will not last as long. So, if you do not mind repairing a heater every couple of years, you should get by without much maintenance.

Electric garage heaters that are more reliable can last longer. Still, it would be best to disinfect them daily, check the power inlets for breaks, and monitor the heat outputs to ensure they are working correctly.

If you do this daily, the more costly heaters will cost less in the long run than replacing many lightweight heaters.

5. Safety Features

Electric garage heaters can be unsafe if not built, set up, and used correctly. Fortunately, many manufacturers have started to include protective features such as a tip-over system, overheating protection, and a cool-touch feature to make the product as accident-proof as practicable.

Overheating Protection

Almost all electric heaters would have this helpful feature. It is intended for days of continuous use where the air temperature will vary by many degrees, allowing the heater to overheat.

When this occurs, the overheating safety detects the rising temperature and turns off the heater to prevent exterior damage to the garage and internal damage to the heater.

Cool-touch Case

Since wall-mounted and portable garage heaters are frequently set up or placed in places where passing children or adults come into contact with the heater’s sides, this function is mainly used for them.

Heaters without this protection option will cause severe burns, but the cool-touch feature allows you to touch or grab the heater’s exterior without hurting yourself.

Tip-over Shut Off Switch

This feature is convenient when you wish to use it for any room in your home for heaters. The tip-over safety switch on your heaters will automatically shut off the heater if it is well tipped over.

The tip-over protection will prevent the appliance from overheating due to having less than optimal airflow while lowering the chance of causing a fire.

Fortunately, it is rare not to find this feature in a space heater. With this, you can rest assured that nothing will happen if an accident happens, whether you, your kids, or your pets accidentally knock your heater over and you do not notice it immediately.

6. Other Features to Consider

Electric garage heaters have evolved with the times and now provide many extra features that may help your garage stay warm. Evaluate the features mentioned below to see if any are necessary for you to keep warm when working in your garage.

  • A handle: Having a Handle will allow you to move your heater of choice easily, so if the heater does not have a cool-touch case, you can adjust the heater without turning it off and letting it cool.
  • Louvers: These are a type of shutter with horizontal slats angled to allow air to flow in a specific direction of your choice.
  • Extended cords: Using a heater with one of these would allow you to position the garage heater anywhere within reach of an outlet, thus extending the possible areas to set up and keep warm.
  • Wheels: Getting a heater with wheels will allow you to move your heater around with ease without having to pick it up. If you plan on getting a heavier heater, look for one with wheels to save you some hassle.
  • Wi-Fi Feature: Some heaters come with a Wi-Fi function that will allow you to adjust the said heater’s temperature via an app on your phone, thus giving you a makeshift remote control for your heater.

Final Thoughts

Overall, we know finding a heater for your garage can get a bit upsetting at times, but we hope you have found this article helpful!

We also wish to help you find the heater of your choice from the list of highly-rated heaters and provide you with enough information to help you look for that perfect heater you need to keep you comfortable and warm for your work.
