My experience working with different types of heaters allows me to share my expert reviews of a selection of the best garage heaters in this post. I have also shared a practical buyer’s guide that will help you identify the different heaters you can find and the most important features to look for during your search.

Best Garage Heater Buying Guide

Garage heaters can prove to be crucial to homeowners since they provide warmth and a comfortable environment to a part of the house that is usually overlooked but can be great for various activities.

Installing a garage heater will allow you to create a favorable environment so you can continue doing projects throughout the year. When buying a heater for your garage, you first have to understand the different types available in the market, which will allow you to indent the correct model for your needs.

Types Of Garage HeatersTypes Of Garage Heaters

A quick hunt online will reveal to you that there are different types, brands, and models of garage heaters that you can buy, each variant comes with a set of features, as well as specific advantages and disadvantages.

Infrared Heaters

Regarded as one of the best types of heaters for a garage – low-intensity infrared heaters are highly effective in making you feel warm. The infrared technology allows the heater to radiate heat throughout the space by heating the objects that the infrared rays hit as opposed to warming up the surrounding air. With an infrared heater, you’ll feel the warmth more quickly since it will heat the objects and people first. Whereas the heating the entire area will take time.

Radiant Heaters

The design of radiant heaters also works similarly to infrared heaters, which heats objects and items first, rather than blowing out hot air. Anything in the radiator’s direct line-of-sight will get heated and start radiating heat, thus warming you up more effectively.

The constant heat supply is the greatest advantage of radiant heaters, making them more suitable for commercial spaces and workshops. You can find radiant heaters that are powered by electricity, natural gas, or propane.

Fan Heaters / Space Heaters

Based on the principles of conventional heaters, fan or space heaters use a fan to distribute and speed up the heating. Although they provide gradual warming that makes the environment comfortable, fan heaters can be noisy.

Even though their quick heating process is faster, the lack of a thermostat means that you will not be able to easily control or monitor the heat supply.

More user-friendly variants are equipped with an in-built electric ignition spark that turns the heater on while the fan distributes heat. You can find industrial and domestic versions of fan heaters.


Ceramic heaters are fundamentally the same as conventional fan heaters, with a ceramic heating element that is heated using electricity, which emits better heat, which is then distributed by a fan.

Their improved efficiency of heating makes them more suitable for heating large rooms.

Quartz Halogen

Quartz halogen heating technology combines infrared radiation and metal reflector sheets to provide better heat radiation than infrared heaters to give off heat in a specific direction.

It is most efficient in quickly heating objects and people but not the surrounding air.  The heating of a Quartz Halogen heater is comparable to the sun’s heat, which makes them ideal for a large room and outdoor spaces.

Propane / Natural Gas

As you may have guessed by the name of these heaters, they are powered by natural fossil fuels rather than electricity, which makes than ma more affordable option. These are one of the most prevalent heater types used in garages because they are portable and work based on a controlled flame. Their ability to provide a high amount of heat for an extended period also makes them suitable for industrial use.

In terms of safety, you have to be extra cautious when using Propane / Natural Gas heaters because leakage of gas can be extremely dangerous. Therefore, these heaters should only be used in well-ventilated areas to avoid potential hazards.


Portable or freestanding heaters have a compact design that makes them easy to move around in any space and around the house. Their easy movability allows you to place them exactly where you need then for better heating. However, freestanding units can be a tripping hazard, especially if you move around too much during work.

Wall Mounted

As the name suggested, these heaters are secured to a wall that keeps the wiring and fuel tanks away from walk paths. They come in a variety of energy options, sizes, and prices. However, it is important not to keep the cords of wall-mounted heaters because they too can be a tripping hazard.

Safety Features to Consider in a Garage HeaterImportant Safety Features to Consider in a Garage Heater

Given how these heaters constantly produce heat, potential electric faults or fire hazards are likely outcomes, thus the necessity of safety features just in case. Select models equipped with:

Overheat Protection

It is typical for heaters to run for extended periods while you work, especially during winter, so the probability of overheating is high. Considering, a heater with overheat protection features will be critical to detecting when the heater is giving too much heat and automatically switching it off to prevent damage.

Tip-Over Mechanism

With an appliance like a heater, you can never be too careful because accidents sometimes happen, such as the heater tipping over, which can be a dangerous fire hazard.

The tip-over mechanism in a heater is a useful feature that allows the unit to sense when the model has been knocked over and is immediately switched off.
