What To Look Out for When Buying Garage Heater

Before you make a final buying decision, you need to put into consideration various factors. Some of the thugs to look out for when buying a garage heater include;

Consider the Type of Garage Heater

First and foremost, it is important to know the various types of garage heaters so you can choose the most appropriate for your needs. There are three types of garage heaters depending on the purpose that one intends to use them for. They include;

  • Electric/ fan-forced garage heaters– These are the most common type of garage heaters that come with an integrated fan. They convert electrical energy to heat which is then dispersed around using a fan. This type of garage heater is easy to install and produces a lot of heat to warm a room quickly.
  • Radiant or Infrared Garage Heaters– These are types of garage heaters that provide simple and direct heat to objects in a room. So unlike most electric garage heaters, radiant heaters are not powerful enough to heat the entire space; rather they heat specific areas or the objects in question. The drawback, therefore, is that you need to be close to these heaters to enjoy their benefits.
  • Diesel/Kerosene/Natural Gas– Heaters that use kerosene, diesel or natural gas can heat garages very quickly and you do not need to have an electricity supply to use them. Besides, they are a great option for heating larger areas. However, a problem with these heaters is that they can be dangerous when used in enclosed areas. Hence, they may not be very recommendable for garages.

Check the Heater’s Range

Heat range is the measure of the area that your heater can comfortably warm up. Heat range is measured in British Thermal Units (BTUs), which describes how fast temperature for a particular space can be raised. BTU is mostly used for gas heaters while watts are used for electric heaters. The more BTUs and watts a heater has, the more space it can heat.

For this reason, it is important to measure the space of your garage so you can find a heater with the right BTUs. Furthermore, it is recommendable to look for a heater with slightly more power than the suggested space that it can heat. Radiant or infrared garage heaters are great for heating smaller spaces while gas-fuelled heaters do a great job for larger spaces like industrial job sites.

If your garage is large, consider a garage heater with about 4,000 to 5,000 watts. In most cases, a 3-car garage may require 50,000 BTUs. Be sure to use a BTU calculator if you are unsure about the BTU needed to heat your garage space.

Safety Features

It goes without question that the safety of your garage heater is of utmost importance. When shopping for a garage heater, look for safety features like heavy-duty housing, overheating protection, cool-touch housing, adjustable louvers, a tip-over switch and many more.

Fixed or Portable Design

Do you intend to move the garage heater from one place to another? Well, it will be best to pick a portable heater that allows you to focus the heat where you need it most. However, if portability is not imperative to you, then you should consider getting a fixed heater. You can mount them on the ceiling or wall, depending on your preference.

Noise Levels

Before you make your purchase, it is wise to check the specs of the heater including the noise level. Of course, you want a heater with a quiet operation so that you won’t have to worry about noise disturbance when the heater is running. This factor is especially important if you intend to use the garage space for other activities.

Type of Insulation

The other thing to keep in mind is the type of insulation that you want for your garage heater. Do you want a heater that requires to be plugged to an existing power outlet (110V) or one that needs to be hardwired (220V or 240V)? The former model is easy to use as you just need to plug the heater to a power outlet that is near your workspace through a power cord.

On the other hand, a hardwired garage heater will need to be installed by a professional electrician. This way, they can ensure that it is working properly and safely.

Effective Garage Heating Tips

Here are some tips to help you heat your garage more effectively.

Pick the right heater

The heater you choose should be able to heat your garage more effectively. To ensure this, first, measure the size of your garage to know the power that will meet your demand. You should also measure the ceiling height as very high ceiling heights will require a more powerful heater.


Believe it or not, the environment of your garage may affect your heater. This is because garages that have less insulation are likely to affect the temperature that your garage heater is capable of achieving.

Adding insulation will help to prevent the escape of heat from your garage and lower your heating bills significantly. To prevent draught, ensure that you put high-grade insulation on the walls and ceilings. You should also ensure that the windows and doors are well insulated as gaps around them can cause heat to escape. Alternatively, you can seal the gaps using caulk or sealant.

Right Installation

If you have opted for a heater that needs to be hardwired with its circuit and switch, make certain that you hire a certified electrical contractor.


Truth be told, finding the best garage heaters can be overwhelming due to the number of models available. Nonetheless, there are a few models in the market that stand out from the rest. The above garage heaters are capable of heating your garage to ensure optimum condition and functionality.

So if you are in the market for a garage heater, these products are a good place to start.

This includes things like heat range, heat source, safety features, size of the garage, availability of power outlets and many more.
