DR-975 Dr Heater Garage Electric Heater, Wall/Ceiling Mounted with Remote Controlled Thermostat

Review

This is an upgraded version of the previous Dr. Heater DR-966 model. The device features an adjustable thermostat (50-90 degrees) and provides a power output of 4000-7500 Watt with a possibility of remote control. It can be mounted on the wall or ceiling, which adds some flexibility. Five adjustable louvres allow changing the direction of the heat flow.

What we think

This Dr Heater garage heater is sturdy and durable. It will cope with large rooms heating (up to 1000 sq. ft), but it takes time for the heat to be evenly distributed. An adjustable thermostat works nice.

PROS

  • exceptionally well-made & durable;
  • a lot of safety features;
  • adjustable louvres;
  • suits for larger rooms heating.

CONS

  • it is noisy;
  • it takes about 2 hours to heat up a 800-1000 sq. ft. room.

Fahrenheat FUH54 240-volt Garage Heater

Review

Fahrenheat FUH54 is one of the Amazon’s best-sellers. Thanks to its compact design, it is a really space-saving option. It is easy to mount on the ceiling or on the wall, and its adjustable louvres allow heat flows regulating. The device works quietly.

What we think

This is, probably, the best electric garage heater for small and medium-sized rooms. It is compact and powerful enough to raise the temperature to 135 degrees! It lacks settings but does its job well.

PROS

  • a robust construction, heavy-duty materials;
  • compact but powerful;
  • heats up to 500 sq. ft. effectively;
  • easy to mount;
  • produces little noise.

CONS

  • not portable;
  • lacks some essential settings.

Dr. Infrared Heater DR-988

Review

The Dr Infrared garage heater comes with an adjustable thermostat and replaceable power cord. With the maximum power output of 5600 Watt, it is capable of heating up to 600 sq. ft. The device has an adjustable thermostat, which allows an easy regulation of power and temperature. It is easy to use, powerful and well-made.

What we think

This is a small garage heater for medium-sized garages and basements. It’s a pity you can’t hang it on the ceiling, though it does its job very well while standing on the floor. You’ll appreciate it when you’ll need to fix your car in winter.

PROS

  • robust and durable;
  • powerful enough to heat a 600 sq. ft. room;
  • a lot of safety features;
  • an adjustable (low to high) thermostat.

CONS

NewAir G73 Hardwired Electric Garage Heater

Review

This is a heavy-duty heater for severe weather conditions – it will never let you down even in the coldest months of the year. The device is non-portable: it is intended for mounting somewhere on the wall and hardwiring. It is recommended to hire a professional electrician to install it. Despite its compact size, the heater is powerful enough to warm up 500 sq. ft. A built-in thermostat and regulated louvres add it flexibility.

What we think

This Newair garage heater is an excellent option for medium-sized workshops and garages. It is small and surprisingly powerful. If you find an optimal position for it to hardwire, you’ll never experience problems with heating anymore, even in winter. But be prepared to see hefty bills in the end of the month because it consumes a lot.

PROS

  • a very robust all-steel body;
  • consistent operating;
  • basic safety features available;
  • a swivel plus adjustable louvres allow changing heat waves direction.

CONS

  • it is not portable;
  • power-consuming.
