 Top #1 Pick: Mr. Heater Maxx Natural Gas Garage Heater

Mr. Heater Maxx Natural Gas Garage Heater

For its price, the Mr. Heater Maxx is the king among natural-gas-fed heaters.

High output heater, it is powerful enough to heat most large garages, barns and shops without being too overwhelming.

The cabinet is built to last and offers easy outside access to the thermostat, gas connection and A/C terminals — uses only 115V AC to run the fan which pulls cool air from the back and pumps it out the front.

 ⭐⭐ Best Garage Heater for 2-3 Car Garages ⭐⭐

At 50,000 BTU, it will heat spaces up to 1250 square feet relatively quickly. I do, however, recommend buying Mr. Heater’s thermostat which is sold separately.

You can also use w/ propane cylinder thanks to a gas-to-propane conversion kit.

While MH60NG is a specialized heater, designed for large-sized areas, the Maxx Heater gives a wider breath of options and is more economical.

Modine’s Hot Dawg heater runs on natural gas – although you can convert it to propane if needed.

Certified for commercial + residential, it’s ideal for quick and efficient heating of 3 car garages, barns or warehouses even during the coldest winter days.

Very quick heating — Just turn it on and in 15-20 minutes you’ll feel the different in temp.

 ⭐⭐ Best Garage Heater for Large Garages ⭐⭐

Hot Dawg Heater gets rid of the harmful byproduct of the gas-burning via a small pipe-vent which can either go through the wall or ceiling, depending on where you have installed the heater.

Modine Hot Dawg Gas Heater is also a very quiet garage heater. Being one of the quietest heaters on the market means it is a little expensive

Installing can be a bit tricky, though — Firstly, it’s not the lightest heater, making it kind of difficult to lift up and secure to the wall or ceiling. You’ll need to make sure the gas inlet and exhaust pipes are securely connected.

Very durable heater which should last multiple years.

Heating distribution is optimized thanks to a Spiral Steel Fin Heating element positioned in front of the fan. It’s copper brazed with spiral steel fins making the heater ideal for open spaces such as a warehouse or barn.

The Fahrenheat FUH724 is an electrical heater — it’s a significant upgrade from its predecessor, the Fahrenheat FUH54.

Plenty of power at 7,500 Watts it can provide up to 26,250 BTU of heating power — enough to heat a 2-car garage, medium-sized shop or a barn relatively quickly.

In terms of mechanical build, this heater has quite a lot of perks.

 ⭐⭐ Best Electric Garage Heater ⭐⭐

Firstly, its mounting bracket is adjustable, which means you can choose to install on your garage wall or ceiling.

Additionally, the cabinet is treated with an epoxy coating which gives it excellent corrosion resistance. So, once you have it installed, get used to seeing it on that spot for the next several years at least.

If you want, you have the option to downgrade power to 5000W by re-wiring (provided in the instruction manual). This could be handy if you find your workshop or garage becoming unbearably hot despite selecting a low setting.

You can wire it yourself using a 12 gauge wire fused at 20 Amps or 8 gauge wire fused at 40 Amps.

#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.


  • Brand: Fehrenheat

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

#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.
