#6.) Fahrenheat 240-Volt Garage Heater (FUH54)

Fahrenheat 240-Volt Garage Heater

Check Price Button

2 things stand out w/ the Fahrenheat FUH54.

First, it has a delayed fan operation to avoid blasting cold air when you turn it on, and two, it is electrically powered.

Don’t get me wrong, at 17,065 BTU, it is powerful enough, and while it won’t be able to heat entire halls, it will also not throw harmful emissions in the air while heating your garage workshop. The fan pushes air up to 16 feet in calm conditions.

 ⭐⭐ Best Garage Heater for 1-2 Car Garages ⭐⭐

Fan will only start spinning when the heating element is hot, which is pretty nice touch by the designers – it also keeps on spinning until the element cools off completely – the saved utility costs will help decrease your electricity bill.

You have two modes of operation to choose from: low and high. At ‘low’, the heater has a power output of 2500W, which is excellent for slower but more economical rate of heating, and at ‘high’, the output is 5000W.

  • Size: 11.25 x 14 x 12.5
  • Weight: 24 pounds

  • Rugged, heavy-duty, durable
  • Best heater for basements or smaller garages

#7.) King Electric Single Phase Garage Heater (KBP2406)King Electric Single Phase Garage Heater

Check Price Button

King Electric Phase Heater is designed with a selectable wattage fucntion which allows you to choose the most adequate power for your garage.

While the maximum wattage of this model is 5700 Watt, you can choose a number of other options – 950, 1900, 2850, 3800 and 4750 – by simply re-arranging a few wires during installation. What this does is it allows you to choose how fast you want the air in your garage to heat, and at what economy rate. Lower wattage will heat cubic feet of air slower but will save power in return.

⭐⭐ Best Garage Heater for 2 Car Garages ⭐⭐

Installation is easy. Securely fasten the mounting bracket of the heater to a wall or ceiling and tighten the knobs after selecting the most appropriate air discharge angle.

Heater has 2 channels of operation: ‘Heat’, which will turn the heater on and will spin the fan, and ‘Fan’, which will just spin the fan.
