10 Best Garage Heaters Propane 2025 in the United States

The Mr. Heater Portable Buddy Heater MH9BX is a solid choice for anyone needing a propane heater, whether for a garage, workshop, or outdoor space. With a versatile BTU rating of 4,000 to 9,000, it effectively warms areas up to 225 square feet, making it suitable for small to medium-sized spaces. Its radiant heating technology offers a cozy warmth that feels similar to natural sunlight, directly heating objects and people instead of just the air, which can be a significant advantage in chilly environments.

Portability is one of its strong suits, featuring a fold-down handle and the ability to connect to both 1 lb. and larger 20 lb. propane tanks. This flexibility means you can easily move it around or set it up wherever you need heat. Additionally, the Piezo igniter allows for quick, reliable starting without the need for matches, which is convenient for users who prefer a straightforward operation.

Safety is another highlight; the heater is equipped with a tip-over switch that ensures it turns off if accidentally knocked over, and it also includes a low-oxygen safety shut-off system. This makes it a safer option for indoor use, although it’s crucial to maintain proper ventilation when using propane heaters indoors. Despite its strengths, there are a few limitations. While it’s designed for indoor use, users should be aware of the need for ventilation to avoid carbon monoxide buildup. It also has a relatively short burn time, with only 6 hours on the low setting, which may require frequent refueling if used extensively. Additionally, the unit's design is fairly basic, which might not appeal to those looking for a more aesthetically pleasing option.

The Mr. Heater Portable Buddy Heater MH9BX serves as an efficient, reliable, and portable heating solution that emphasizes safety and ease of use, making it ideal for garage enthusiasts, campers, or anyone in need of reliable warmth in smaller spaces.

The Mr. Heater MH540T is a portable propane heater designed for outdoor use, making it ideal for sporting events, camping, and other outdoor activities. With a BTU rating of up to 45,000, it offers adjustable heating options at high, medium, and low settings, allowing users to customize warmth based on their needs. The 540° radiant coverage ensures that heat is distributed widely, effectively warming both people and objects nearby.

One of the standout features is its safety protection; the tip-over shut-off mechanism is crucial for preventing accidents, especially in outdoor environments where stability can be an issue. Additionally, the secure connection to the propane tank helps prevent leaks, adding an extra layer of safety.

Portability is another major advantage, with a lightweight design (weighing only 5.5 pounds) making it easy to transport. The heater also offers dual ignition options, including a push-button TE valve and a manual lighting option, which enhances usability. This heater is designed exclusively for outdoor use, which limits its applicability in enclosed spaces like garages unless they have proper ventilation. The heating coverage is capped at approximately 100 square feet, which may not be sufficient for larger areas. While it heats effectively, it may struggle in very cold conditions or in drafty spaces.

The CAMPLUX Propane Heater offers a versatile heating solution for both indoor and outdoor spaces, with a BTU rating adjustable between 6,000, 12,000, and 18,000 BTUs. This makes it suitable for warming areas up to 450 sq. ft., which is ideal for garages, patios, and small workshops. One of its strongest features is the dual safety mechanism with an oxygen depletion sensor (ODS) and tip-over protection, ensuring safe operation even in enclosed spaces or if accidentally knocked over.

The heater is quite portable, featuring five durable casters with brakes and a convenient carry handle, making it easy to move around different locations. The windproof design also adds to its portability and usability outdoors as it keeps the gas tank secure within the cabinet. However, it does require a 20lb propane tank and the fuel consumption will vary based on the heat setting, lasting up to 69 hours on the lowest setting, but considerably less on higher settings. Ignition is straightforward with its single control knob and piezo mechanism, which is user-friendly but does need manual operation.

The heater operates quietly, under 30dB, creating a peaceful environment for work or relaxation. While it eliminates the need for electricity, which is a plus during power outages, it does mean that it relies entirely on propane, so ensuring you have a sufficient fuel supply is critical. In terms of weaknesses, the reliance on propane can be seen as a drawback due to the need for regular fuel purchase and handling. Additionally, although portable, its compact size may not be sufficient for larger spaces beyond its specified coverage area. The CAMPLUX Propane Heater is a reliable option for those needing a portable, safe, and efficient heating solution for medium-sized areas, particularly where electricity may not be available or desirable.
