6. Dr. Infrared Heater with Plug

51+hfll8cYL. SL500

For those looking for a budget-friendly but effective garage heater, the Dr. Infrared DR-988 is one of the best available options. From small construction site projects to DIY activities in the basement, this heater serves its users in many ways.


  • Material: Red steel exterior with a front safety grille to help prevent accidental burning.
  • Watts: 5600
  • Thermostat Control: 45-95 degree accurate electronic thermostat with a dial control button.
  • Ease of installation: This unit is one of the easiest ones when it comes to any kind of set-up. Simply plug in the heater and you are all set. It also comes with a handle to add portability.

With the exterior grille, completely enclosed motor and overheat protection, this unit is one of the safest ones to use compared to others in its class. 

While not the most powerful heater on the market, the 5,600 watts it cranks out should be enough to handle most smaller projects. The thermostat is also easy to use and will maintain whatever temperature you set automatically. The overheat protection is a nice feature here as well as that will add longevity to the heater. 

The Dr. Infrared DR-998 heats any room it’s in quickly and evenly, providing fast and consistent warmth through its fan. 

One flaw with this unit, however, is the fact that it cannot be mounted. There is no way to use brackets and attach this thing to a wall or ceiling. Instead, it must be on a flat surface with its box-like design. The portability of the unit helps make up for this, but it would still be nice to be able to mount it for convenience purposes. 


  • Budget-friendly
  • Heats quickly and evenly
  • Easy installation
  • Portable


  • Customer reviews include issues with longevity
  • Louder/noisier than comparable fans
  • Not mountable

This heater certainly is not the best of its kind, but it’s toward the top of the list. It is perfect for those small to medium-sized projects and is very easy to move around a larger worksite if need be. Some of the long-term issues mentioned with this seem to be few and far between. The filter is easy to clean on this, as owners can either use water or a normal vacuum. Plus, the unit does come with a one year warranty. Dr. Infrared is a trusted name in the heater industry and makes quality products. The DR-998 is no exception and should provide great value for any buyer. 

7. NewAir G56 5600 Watt Garage Heater

51rImNZCRzL. SL500

The NewAir G56 5600 Watt Garage Heater is a great option for those looking to stay warm while they work. While not designed for massive construction sites, this unit is perfect for workshops, garages and other small to midsize work areas. 


  • Material: The motor is full enclosed inside a steel exterior with a grille covering the front of the heater to prevent accidental burning. The exterior uses a black powder-coated finish.
  • Watts: 5600
  • Thermostat Control: The thermostat features manual controls with a 45-95 degree range and automatically maintains whatever temperature you set it to.
  • Ease of installation: Setup is as easy as it gets. Set the heater on a flat surface, plug it in, and it will be good to go.

This heater is very similar to the Dr. Infrared DR-998. The design of both heaters is borderline identical. Plus, they feature the same wattage and are best used for the same kind of small project areas. The NewAir G56 can heat up to 800 square feet, however, while the Dr. Infrared unit can only reach up to about 600 square feet. Similar to the DR-998, the NewAir G56 utilizes a safe, portable design that is made to help prevent users from burning themselves. A thermal cut-off system is also in place to ensure the unit does not overheat. Heat is also emitted from an interior fan, which is also enclosed. 

Users must ensure that they have the right outlets for the unit as it features a 3-pronged, 240V plug. As mentioned, it is a portable unit that uses a handle at the top of the unit that allows for easy transfer around a worksite. 


  • Easy set-up and use
  • User-friendly thermostat control
  • Very safe design
  • Covers 800 square feet
  • Portable


  • Long-term quality concerns
  • Non-mountable design
  • Can run up an energy bill 

It’s best to just be reasonable and realistic with your expectations of this heater. This unit works best when used for just trying to bring some warmth into a smaller work area. If users are looking to bring this to a huge construction site or single-handedly power a “man-cave” in the garage, they will be disappointed and staring at a costly electric bill. For those just looking to do some at-home work while trying to stay warm during the colder months, this will work perfectly. 

Final Verdict

Out of all the choices that we have presented today, we could most highly recommend the Fahrenheat FUH724 as the best electric garage heater in this review.

A few of the biggest reasons that we like this model the most is that it has an adjustable thermostat, tons of power, and an automatic shut-off function to keep your garage or workspace balanced at the perfect temperature.
