10 Best Garage Heaters Propane 2026 in the United States

The ProCom ML100TBA-B Ventless Propane Gas Blue Flame Space Heater offers a strong 10000 BTU rating, making it capable of heating areas up to 500 square feet. This makes it suitable for small to medium-sized rooms, such as an office, bedroom, or living room. For portability, the heater provides flexibility with included wall mount and base feet options, allowing for both wall-mounted and floor-standing use. Weighing 15.87 pounds, it's relatively easy to move if needed.

Safety is a priority with this heater, featuring a push-button ignition for straightforward use and a built-in oxygen depletion sensor (ODS) that automatically shuts off the heater if oxygen levels drop too low, adding a layer of protection against carbon monoxide. This model boasts thermostat control with high, medium, and low settings, offering customizable comfort levels. Additionally, it operates without the need for electricity, which is convenient during power outages. However, as a ventless heater, it's crucial to ensure proper room ventilation to prevent any potential accumulation of gases.

Despite its practical design, the heater's fuel consumption and running cost can add up, especially if used frequently. In terms of aesthetics, the heater features a modern, slim profile that fits well into various room decors. It is best suited for those who need a reliable heating solution without relying on electrical power.

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.
