10 Best Portable Gas Heater 2026 in the United States

The Mr. Heater MH540T is a powerful portable propane heater designed for outdoor activities like camping, hunting, and tailgating. One of its key strengths is its impressive heating capacity, offering up to 45,000 BTUs with three adjustable heat settings (high, medium, and low). This allows users to customize the warmth to their preference, making it versatile for different weather conditions. The 540-degree radiant coverage is another standout feature, providing wide-reaching heat by combining a 360-degree burner and a 180-degree swivel bracket, effectively warming both people and objects directly around it.

Safety is a priority with this heater, featuring a tip-over safety shut-off that automatically turns the heater off if it’s knocked over, preventing accidents. Additionally, the secure, leak-free connection ensures dependable and safe operation. In terms of ease of use, it boasts a push-button TE valve for quick ignition and also offers a manual match-lit ignition as a backup. However, it’s important to note that this heater is for outdoor use only, which limits its versatility.

Portability is a major plus, as it’s lightweight at just 5.5 pounds and doesn't require any assembly, making it easy to move and set up. On the downside, because it uses propane, it may not be the most energy-efficient option compared to electric heaters. The Mr. Heater MH540T is an excellent choice for those needing a reliable and powerful source of outdoor heat, particularly for active outdoor enthusiasts.

The ProCom ML100TBA-B is a portable gas heater designed for home and office use. It offers a heating capacity of 10,000 BTU, which is sufficient to warm up to 500 square feet, making it ideal for bedrooms, living rooms, and home offices. The heater operates on liquid propane, which is a common and readily available fuel type. One of its significant advantages is the inclusion of a thermostat control with High, Medium, and Low settings, allowing you to adjust the heat output according to your needs. Safety is a priority with this model, featuring a built-in oxygen depletion sensor that shuts down the heater if carbon monoxide levels are too high or if there is a lack of oxygen, giving you peace of mind.

The heater also boasts push-button ignition for easy start-up and does not require electricity, making it reliable during power outages. Its portability is enhanced by its compact design and the inclusion of wall mount hardware and base feet, allowing you to place it on the floor or mount it on the wall. However, it weighs nearly 16 pounds, so it might be a bit heavy for frequent relocation. Another downside could be the lack of advanced features like timers or remote controls found in some other models.

Despite these minor drawbacks, its modern and stylish design ensures it fits seamlessly into most room decor. Energy efficiency may not be as high as some electric heaters, but it balances this with the benefit of not relying on the electrical grid.

With a substantial heating capacity of 30,000 BTU, it can comfortably warm larger spaces. The use of propane as a fuel type means it’s quite efficient and convenient for areas where electricity might not be reliably available.

This adds to its portability, making it easy to move and set up in different areas as needed. Safety is a priority with this model, which includes a built-in low oxygen sensor to prevent hazardous conditions. However, it's worth noting that while the heater operates without electricity, the blower requires power. This means that during a power outage, the heater will still work, but without the blower's enhanced heat distribution.

The unit is relatively lightweight at 1 pound, so transporting it should be hassle-free. The black color and compact design ensure it blends well with most interiors. On the downside, some users might find that the need for an AA battery for ignition and power for the blower adds a layer of maintenance. Nevertheless, the Heatstar 30000 Btu Vent Free Radiant Propane Heater is an efficient, safe, and portable option that suits various heating needs, especially in areas prone to power outages.
