Natural Gas Garage Heater Reviews

1. Modine Hot Dawg

When it comes to installing a natural gas heater in your garage or other non-insulated space, you want something that won’t take up too much space or make too much noise.

Specifications:

  • Material: Aluminum and steel
  • Heater power: 45,000 BTU
  • Thermostat Control: No
  • Easy installation: Yes
  • Safety issues: No oxygen depletion sensor

Fortunately, the Hot Dawg model from Modine shines in both areas, making it a top choice for anyone looking for a safe and reliable heat source. In fact, this machine is so good at what it does that it works well for commercial, industrial, or residential purposes.

EDITOR'S RATING:

One of the best reasons to get the Hot Dawg is its size. It’s more compact than most other models, meaning that you can keep it out of the way relatively easily.

Also, because it doesn’t require much clearance (one inch on all sides) and it can work in practically any direction, installation is much simpler than with most other heaters.

As far as heat is concerned, this one is in the middle of the road. While it’s not as hot as some other ones out there, it does provide enough warmth to work in a space up to 1200 square feet.

Overall, it should be perfect for most garages or work areas, as long as you don’t want it to get too hot.

Thankfully, though, the motor is permanently lubricated, so it requires much less maintenance, and it is certified to be 80% energy efficient so that you won’t add too much in the way of utility bills.

This is one of my favorite garage heaters overall, and it'll definitely make the list of the very best of the year.

Pros

Cons

2. Mr. Heater Big Maxx

If you have a large garage or storage unit and you want to make sure that you can stay warm all winter long, then you may need something as robust as this model from Mr. Heater.

Specifications:

  • Material: Aluminum and steel
  • Heater power: 80,000 BTU
  • Thermostat Control: Yes
  • Easy installation: Yes
  • Safety issues: No tip-over switch or oxygen depletion sensor

The F260560 produces up to 80,000 BTUs of heat, meaning that it works well for commercial or industrial spaces up to 2000 feet. If there is any insulation in the area, then it can work up to 2500 feet.

EDITOR'S RATING:

One downside to this model is that it doesn’t come with all of the ventilation equipment included.

You have to buy it separately to ensure that you don’t wind up pumping natural gas or propane fumes into the area while it works.

Nonetheless, it’s high output, and simple installation still makes it a worthwhile investment. It even comes with a conversion kit so that you can turn natural gas into liquid propane.

This particular model can connect to a thermostat so that you can control the temperature, and it only needs an inch of clearance on top, making it an ideal choice for mounting to the ceiling.

It does, however, need eight feet below the unit, so if your space has a low roof, you might need to measure it just to be safe.

Overall, if you’re looking for something extra warm, this is a great option.

Pros

Cons

3. Mr. Heater Vent Free

Next, we have a natural gas heater that almost functions as a space heater if you want it to, although we would highly suggest mounting it to the wall.

Specifications:

  • Material: Plastic and metal
  • Heater power: 30,000 BTU
  • Thermostat Control: Yes
  • Easy installation: Yes
  • Safety issues: None

This model from Mr. Heater comes with feet so that you could keep it on the floor if you like, but since it can tip over easily like that, we don’t recommend doing that.

EDITOR'S RATING:

Overall, this unit is designed for smaller spaces as it can only reliably heat up to 1000 square feet.

It uses a blue flame convection heating element and a built-in blower fan to distribute air, although it can only go so far. The BTU rating is lower than the other ones we’ve seen, with just 30,000 max.

Fortunately, it comes with an easy to use thermostat knob on top so that you can control the heat much more easily.

Installation is a snap thanks to the size and weight of this heater, so you should be able to do it yourself as long as you know how to access the natural gas line.

This unit can also work on propane if necessary, although it cannot use a conversion kit if you are planning on utilizing one.

Finally, this heater comes with a couple of extra safety features, including an oxygen depletion sensor that shuts the whole thing off if there is too little ventilation.

Also, if it tips over then it will shut off, and it won’t overheat either. As such, this is one of the safest heaters you can find.

Pros

Cons

4. Mr. Heater Radiant Heater

So far we’ve been looking at natural gas heaters that use a blower to distribute warm air throughout your garage or work space.

Specifications:

  • Material: Metal with chrome plating
  • Heater power: 25,000 BTU
  • Thermostat Control: Yes
  • Easy installation: Yes, with video instruction
  • Safety issues: Burn hazard

However, if you only want to heat a particular area, rather than your whole interior, then you might want something like this model from Mr. Heater.

EDITOR'S RATING:

It uses radiant infrared heat to create more targeted results, which is perfect for keeping a work area or vehicle warm throughout the cold weather.

Even though this unit is limited to just 625 feet, it’s ideal for situations where you want to keep one area hotter than another. For example, if you just want to make sure that your car stays heated then you can save money by using this kind of heater.

What also makes this model so fantastic is that it doesn’t make any noise (no blower) and it uses much less gas to get the job done.

It still requires plenty of ventilation, but installation is a breeze, and you can be up and running in minutes once it’s connected to the gas line.

Best of all, it works without electricity, so you never have to worry during a power outage. Finally, it even comes with a thermostat control for your convenience.

Pros

Cons

5. Dyna-Glo IR12NMDG-1

For the most part, natural gas heaters are designed for garages and other areas that are not considered “indoors” by most practical measurements.

Specifications:

  • Material: Plastic and metal
  • Heater power: 12,000 BTU
  • Thermostat Control: Yes, but limited
  • Easy installation: Yes
  • Safety issues: Burn hazard

In this case, however, the Dyna-Glo Heater is rated for indoor use, provided that you still can ventilate the room somehow.

EDITOR'S RATING:

This means that you cannot mount them inside your home or other insulated area because they require extra ventilation and installation.

Since it still runs on natural gas, this will always be an issue, but it doesn’t produce as much heat, so it’s not as big of an issue with this model.

Overall, this heater is designed to work well for a camper or a single room as a replacement for a standard heating system.

Since it just works with gas or propane (no conversion allowed), you don’t need electricity to operate it.

This also makes installation a breeze as it just uses radiant heat to work. As a result, you can only heat up to 300 feet, but that should be more than enough for a single room.

Unfortunately, this model does not have thermostatic controls, so you have to manage the temperature manually. Also, it just has a high/low setting, so you can’t get an accurate temperature.

Nonetheless, it does come with an oxygen depletion sensor, so it will shut off automatically if there are too many fumes in the area.

Pros

Cons

Final Verdict

If you still have doubts about using a natural gas heater, I suggest you this read, but overall is one of the best possible solutions there is.

If you want high-performance and reliability, then the best option will be to get the Hot Dawg Heater from Modine.

It works well for practically any situation and installation is much easier than you might think. Plus, the lubricated motor requires little to no maintenance, so it will last longer than the competition.

I would confidently call it the best natural gas garage heater available in the market this winter.
