9 Best Propane Garage Heaters - Reviews

1. Mr. Heater Vent Free Propane Garage Heater: Best Overall

Key Features:

  • Battery-powered electric ignition
  • Multiple burner tiles provide even heating
  • Low oxygen shut off system
  • Comes with a 1-year manufacturer warranty
  • Produces 18,000 BTUs of energy

Mr. Heater is an innovative and trusted supplier of high-quality propane garage heaters, and they’ve delivered again with this excellent unit. We had no trouble getting the heater to start using the battery-powered electric ignition system, and the warmth from the multiple burner tiles hit us immediately.

The radiant convection heating system provided an even warmth throughout the garage, and there were no noticeable cold spots. Since several of us were sitting in multiple locations around the garage, it was nice that we could all remove our coats and hoodies and sit in comfort.

Thankfully we didn’t need it, but it was reassuring to know there is a low oxygen shut-off system. If the garage heater senses the oxygen concentration is below safe levels, the system instantly powers off. The intuitive thermostat is easy to use, and we lowered the heat setting when the garage was sufficiently warm. 

After several hours of testing over numerous days, our team has no hesitation in naming this model the best propane heater for the garage

Pros

  • Heats garage spaces up to 500 ft2 
  • Integrated thermostat for precision temperature control
  • Suitable for wall mounting

Cons

  • One of the more expensive propane garage heaters

Who Should Get This? 

This model is an excellent choice for the garage owner that needs a reliable and robust propane garage heater when warming large and cool spaces.

Key Features:

  • Uses advanced Blue Flame technology
  • Built-in carbon monoxide sensor

This wall heater adds warmth to your garage at an affordable price. You can set it up and turn on the heat as soon as the box arrives, as all the installation hardware and brackets come included. You only need to add the propane tank and connect it to the heater using the long 10’ hose and regulator. 

Choose from low, medium, and high heat using the variable control knob. The range of temperatures is ideal for saving money in the warmer summer months and allows you to crank up the heat when the winter weather brings the colder air. 

Dyna-Glo uses its Blue Flame technology to significant effect, and the heat spreads throughout a garage in the same way as it would if you were using your home heating system. 

For your peace of mind, there is a built-in carbon monoxide alarm. Because you can not see this harmful gas, it is essential to have an operational warning system to alert you if it is present in the air.

  • Quick start ignition system
  • Can add base legs for floor mounting
  • Uses an enormous 100 lb. propane tank

If you have a substantial-sized garage or find it challenging to heat to each side of the room, you need a powerful propane heater that can outperform its rivals. This Dyna-Glo unit can warm a 1,000 ft2 area, and because it burns with 99.9% efficiency, it is also environmentally friendly. 

Although you can WALL MOUNT the unit to help clear the garage floor space, there are optional base legs if you prefer floor mounting. For an enhanced runtime, this model works with a massive 100 lb. propane tank so you can relax in your garage without the need for constant refueling. 

This feature could be crucial in an emergency if your property suffers a power outage for several hours. Because there is no requirement to power the unit with electricity, you can stay warm, whatever the outside weather.

We were delighted with the convenience added by the auto-adjust heating system that senses the garage temperature. The intelligent mechanism regulates the heat to ensure it remains at the preset level, with no need for manual intervention.

4. Mr. Heater Big Buddy Portable Propane Gas Heater: Best for Portability

Key Features:

  • Ideal for indoor and outdoor use
  • Connects to lightweight 1 lb. propane tanks
  • Accidental tip-over shut off function
  • Radiant heat technology
  • Attractive black-and-red color scheme

This propane garage heater uses a reliable Piezo sparking mechanism to light the flames instantly. When you turn the single control start knob, a spring-loaded hammer strikes quartz to produce a spark, making this one of the most reliable lighting methods available. We noticed the radiant heat technology quickly distributed heat around the room. 

Our testing garage was much smaller than the 450 ft2 this heater is capable of warming, so we spent most of the time using the low heat setting. In wintertime, the medium and higher warmth options are also useful. It was easy to move the unit because it connects to a small 1 lb. propane tank, and this is an excellent model for taking to a buddy’s garage or tailgating due to its lightweight design.

The manufacturer includes the functionality to connect this model to a remote gas supply, so there’s no need to run out of fuel during extended use. Powerful yet compact, this is the best portable propane gas heater for garage use.

Pros

  • Integrated fan for improved heat distribution

  • Industrial housing protects internal components
  • Produces a maximum 68,000 BTUs of energy
  • Works with 20-volt Max and Flexvolt batteries
  • Meets CSA safety standards

If you do a lot of work in your garage or store materials or tools in the area, there is the risk of accidental damage to your propane heater. However, DeWalt has encased the internal components in an industrial-strength housing unit, keeping them safe from bumps and scrapes.   

Although this model produces a huge 68,000 BTUs of energy on the maximum setting, you can turn it down as low as 27,000 BTUs when you don’t require as much supplemental heat. 

Despite the incredible power of this heater, it has a LOW OPERATIONAL NOISE LEVEL. Remarkably, it can be as much as 50% quieter than many rival propane heaters, making it ideal for when you have friends in your garage. 

You can talk at a comfortable level while still feeling the benefits of the extra heat. Maintenance is straightforward, as you can easily disassemble the unit. For your peace of mind, this propane heater meets CSA safety standards, so you can be confident it operates safely in an indoor environment.

Key Features:

  • 2 units included in the package
  • Thermoelectric safety valve 
  • Pleasant odorless burning 
  • Efficiently burns 0.176 lbs. of fuel per hour
  • Lightweight at only 3 lbs.

An effective way of ensuring heat reaches every corner of your garage is to use 2 heaters that warm separate sides of the building. This 2-pack propane heater set uses a convection heating system to evenly spread warmth, while the thermoelectric safety valve and standing pilot light add an extra layer of safety.

Although this set requires a vented garage space, we found the unit to produce odorless heat. A single 20 pound. propane tank can provide up to 17 hours worth of fuel, which is an excellent feature if you are likely to be heating your garage for long periods. The 10’ connection hose comes in the package, so you can keep the tank a considerable distance from the heater if you need extra space. 

There is no electricity required, allowing you to position the heater away from plug sockets. As each unit weighs a mere 3 pounds, you can quickly move them to where you need them most, which is useful if you have multiple workstations in your garage.

Pros

  • 1 fuel tank lasts up to 17 hours
  • Convection heating system
  • Hose and regulator included with the heater

Cons

Key Features:

  • Swivel valve tank replacement mechanism
  • Built-in oxygen depletion sensor
  • Variable heat settings

The circular heater on top of a stable base has a safety guard for preventing accidental contact with the structure, and the heat distribution covers a 250 ft2 area. There are variable heat settings, producing between 7,500 and 10,000 BTUs of energy depending on the required heat. 

Because this is the ideal propane garage heater for entertaining guests who can sit around the unit, we were pleased to see an accidental tip-over shut-off function. This feature immediately stops the supply of gas to the heater in the event of it falling over. 

When it was time to return the unit, we found the swivel tank replacement mechanism to be as easy as any system we’ve used when disconnecting the propane bottle.

Pros

  • Safe for indoor use
  • State-of-the-art patent-pending technology
  • Does not require electricity or batteries

Cons

  • Not suitable for heating larger garage spaces

Who Should Get This? 

If there are several people in your garage or you use multiple workstations, it can be challenging to heat the entire space. This model’s intelligent design sends out plenty of heat for your space.

8. Master MH-150V-GFA-A 150,000 BTU Variable Output LP Forced Air Heater: Best for Safety

Producing an incredible 150,000 BTUs of energy, this heater can warm areas as large as 3,800 ft2. There is an adjustable heat angle facility, allowing you to direct heat higher or lower depending on where you are working. 

The forced-air heating system provides a steady stream of warm air, and because this model is CSA-certified for use with 100 lb. propane tanks, you won’t need to replace the fuel too often.

A propane garage heater doesn’t have to take up much space. This model provides plenty of heat but won’t add unnecessary clutter to your garage workspace.

How to Choose the Best Propane Garage Heater?

It can be challenging to choose the most energy-efficient propane garage heater due to the wide range of choices on the market. However, some considerations can help you narrow down your choice and find an environmentally friendly model 

However, the question remains, what exactly should you be on the lookout for when buying one of these units? 

Number of BTUs

If you need to heat a substantial garage space, you may need to purchase a unit that produces a high number of BTUs per hour. However, if you have a smaller space, you can reduce energy use, and the amount of fuel you burn, by choosing a less powerful propane heater. 

Many modern garage heaters burn fuel efficiently, so you can still receive plenty of warmth from less vigorous models.

Ignition System

Portability can have a significant effect on the energy efficiency of your propane garage heater. If you are trying to heat the entire room and leave a heater turned on to propel warmth to the other side of the garage, this can use considerable energy. By purchasing a portable model, you can move it to colder areas when one section is warm. If you prefer, buying 2 smaller units could be more efficient than using one larger heater.

If you are using one part of your garage, you can also move the heater to provide warmth to that specific place. Burning less fuel is a crucial aspect of reducing your carbon footprint

Propane Tank Safety

Propane tank safety is vital for energy efficiency. If a unit continues to produce warm air when it is already overheating, this could damage the internal components. If these harmful effects reduce the operational effectiveness of the heater, it could be less energy-efficient.

If a propane garage heater releases gas into the air when there is no flame, this is inefficient and dangerous. A flameout safety system ensures the system shuts down the supply of propane to the heater if a flame is not present. 

It is essential to follow a maintenance program and ensure your heating equipment is safe for use at all times. If you notice any issues, call for repairs by a professional to keep the components in good condition.

Auto-Adjust Temperature Function

It can be challenging to measure the temperature in your garage accurately. If there are drafts that cool down areas that your heater has warmed, it becomes even more challenging to judge the temperature. 

However, you can purchase a propane garage heater that has an automatic heat adjustment feature. This function monitors the room temperature and reduces the heat level if it is above a preset position.

An auto temperature adjustment feature also allows you to leave it at a low setting, so you are only heating the air to a required temperature rather than inadvertently making the room too hot. 

Final Verdict: Our Top Choice

A propane garage heater is ideal for use in the colder winter months, but it is also useful for adding extra heat to your garage in the fall and spring changes. Mr. Heater has produced an outstanding model that excels in every aspect, and it is suitable for small and large garages alike. 

The safety features are impressive, the convenient start-up mechanism is smooth, and the easy wall and floor mounting systems make this a popular choice for many customers. 

Although we enjoyed the warmth provided by numerous superb propane garage heaters, our undisputed favorite is the Mr. Heater Vent Free Propane Garage Heater.
