Fahrenheat FUH Electric Garage Heater

Power Source: Hard wired electric
Heating Method: Forced air
Weight: 24 lbs.

The best choice on our list is the Fahrenheat FUH Electric Garage Heater. This unit takes the top spot because it combines some of the best features across the board into one reliable heater. First, it runs on electricity, so you don’t have to deal with propane or natural gas if that is not your thing. Second, it can be installed anywhere. The handy mounting kit and pleasant square design allow you to mount it in a variety of different places to put the heat exactly where it needs to go. Mounting it on the ceiling can keep the heater out of the way, so you don’t lose valuable floor space in a crowded garage. This heater is not fancy, it is not complicated, and it is not low-grade. It does its job well without fuss and can heat a two-car garage with the flip of a switch.

This heater can crank all the way up to 135 F for large spaces, but it is also safe. It has an automatic shut off that kicks in in the event of overheating or electrical issues. It has adjustable louvers and an included thermostat for precision accuracy in the garage.

The only con for this unit is that it requires a solid mount (included) to hold it up. It weighs 24lbs. It also needs to be hard wired into your garage’s electrical system. This unit does not require any fancy wiring, but it does need to be spliced in. The unit can run on 208 or 240-volt circuits. It can really be installed anywhere. You can put it over your car, in the corner, by the door, or over your workbench. Once installed, the unit works well, provides good heat, and won’t be a hassle. The Mr. Heater F232000 MH9BX Buddy 4,000-9,000-BTU Portable Propane Heater has the best combination of functionality, warmth, safety, and affordability.

  • Provides a lot of heat
  • Can be installed anywhere in the garage
  • Provides targeted precision heat
  • Mounting it up high keeps it out of the way
  • Needs to be wired in for best results
  • Can be expensive to run continuously

2. Best Small Garage Heater – Mr. Heater F232000 MH9BX Buddy 4,000-9,000-BTU Portable Propane Heater

Heating Method: Radiant
Weight: 9 lbs.

Not everyone needs an involved garage heater to get the warmth they desire. Some people just need something small, affordable, and easy to take down and put up. The Mr. Heater F232000 MH9BX Buddy 4,000-9,000 BTU Portable Propane Heater is a compact heater that runs off a small propane tank that can output 4,000 to 9,000 BTUs of adjustable heat. The unit is great for short bursts of heat that won’t break the budget.

Running a large heater can be expensive, and not everyone needs 2,000 sq. ft. of heat or wants to pay for it. This heater is perfect for someone who just needs a little bit of warmth for a short amount of time every once in a while. The upfront cost is affordable, and the operating cost is affordable. It can run at full blast for three hours or half heat for six hours. This heater can also work for camping, outdoor sports events, and yard work since it is easily transportable from the garage to your outdoor activity.

The biggest drawback to this unit seems to be the finicky pilot light. Since the unit is so small, the pilot light tends to go out rather easily, which can be frustrating in windy or drafty situations. The pilot light problems can make the heater hard to light and have caused some people to think the whole unit is defective. Pilot lights can be tricky in general and having a weak pilot light could be an issue for some casual users.

It is also a bulky 63 pounds. Installation is not that complicated, but it does need to be installed on a natural gas line and mounted.

7. Best Natural Gas Garage Heater – Dyna-Glo 30,000 BTU Blue Flame Thermostatic Garage Vent Free Wall Heater

Dyna-Glo 30,000 BTU Blue Flame Thermostatic Garage Vent Free Wall Heater

Heating Method: Convection
Weight: 28 lbs.

Losing power during a period of extreme cold can be dangerous. In extreme situations, it can take days to get the power back on after an ice storm.

The Dyna-Glo 30,000 BTU Blue Flame Thermostatic Garage Heater is a great choice for a natural gas heater because it runs completely without electricity.

It also has a smart electric pilot light, a wrong fuel detection system, and an automatic shutoff in the case that any of these sensors are tripped. This keeps your garage warm without worrying about the safety of a gas heater.

The downside to this heater is that since it runs off of a natural gas line (or 100-gallon propane tank), it will require professional installation in order to get it right. The heater will have to meet natural gas building codes for your area to ensure its safety.

  • No electricity required
  • Can use natural gas OR propane
  • Great for emergency situations
  • Plenty of safety features
  • Requires professional installation

Buyer’s Guide: Picking the Best Garage Heater

Typical Usage

Perhaps the most important thing to consider before buying a garage heater is the typical usage. Some people work in their garage every day and need to keep the space warm constantly. Other people only need to heat their garage maybe once or twice a month. The amount of heat you need, and the frequency of the heat are critical factors to keep in mind. People who do not need to heat their garage regularly might be fine with a small portable heater, while someone who wants a consistently heated garage might want to opt for a permanent fixture. The usage will often dictate the budget as well. Small portable heaters are often more affordable than beefy heaters designed to heat the garage all day.

Garage Features

Is your garage insulated? Is your garage finished? Is your garage attached or unattached? These are questions that you need to ask yourself before deciding on a heater. Unfinished and uninsulated garages will require more heat to keep them warm in the winter. The attached garages can exchange heat with the connected house. You might not want to use an open flame or super-hot heater in an attached garage in case the unthinkable happens, and a fire breaks out. A finished and well-insulated garage will probably require less heat to get it up to temperature and keep it warm longer, so you can probably afford to go with a smaller and safer heater. Not all garages are created equal, and it is important to know what features your garage has before making a purchase.

Power / Fuel Source

There are a variety of different fuel sources for garage heaters, including outlets, hardwired cords, natural gas, or propane. Your familiarity with these fuel sources will influence your decision. Some people use propane regularly, while others have never touched a propane tank. Natural gas heaters are super-efficient and safe, but they require professional installation and more money on your monthly gas bill. Be sure to check what kind of power source the garage heaters use before settling on a final option.


Not all garage heaters are safe for children and pets. Any heaters that use an open flame or exposed electric coils can be a burn risk or a fire risk. Some heaters are hot to the touch and can cause burns to unsuspecting people. These are risks inherent to any number of heaters, so it is important to know the safety features and the safety risks of any heater you are considering. If you have children or a dog that likes to spend time in the garage, you must consider the heating method to avoid accidents.


Some garage heaters require no installation. Portable units can be plugged in or loaded with propane and simply turned on. Other heaters require mounting, hard wiring, or pipe fitting to get up and running. Some installations are complicated and might require the use of a professional to meet building codes and ensure the safety of the unit. If you do not want to deal with an advanced installation, make sure you are getting a portable unit that does not require much work. However, well-built heaters that are installed properly are often out of the way and permanent and require little maintenance after they are installed.

Overall Costs

Cost is a big factor in any purchasing decision. In the case of a garage heater, there are two main sources of cost that need to be considered. First is the upfront cost of the unit. Some garage heaters are expensive on the front end, but they provide a lot of reliable heat for years at a time. The second cost is the cost it takes to run the unit.

This is just as important as the upfront cost. Some garage heaters are extremely expensive to run consistently, whether that is additional money on your electricity bill or frequent trips to the hardware store to get refills on propane. The amount of time you need to run your heater, the size of the heater, and the power source will all factor into how much it will take on a monthly basis to keep your garage at a comfortable temperature during the day.

You could feel like you are getting a good deal on the front end only to find out that the monthly costs are way higher than you expected. You have to consider the running costs in addition to the purchasing cost before making a final decision.
