10 Best Portable Gas Heater 2025 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 Camco Olympian Wave-6 Portable Catalytic Safety Heater is designed for RV use with a heating capacity ranging from 3,200 to 6,000 BTUs, ideal for warming up to 200 sq. ft. Its catalytic heating method ensures efficient and safe operation without the need for an open flame, making it a suitable choice for indoor use. The heater is versatile in placement, offering portability with optional leg stands and the ability to function outdoors.

Weighing 15.2 pounds and with dimensions of 20.6 x 13.6 x 6 inches, it is compact enough for various setups. Safety features include a self-generating piezo starter that lasts for 20,000 starts and a safety shut-off valve, contributing to its reliability and longevity. The heater operates silently without a fan or blower, enhancing the comfort level without noise disruption.

However, it should be noted that this model does not include a fan for forced air distribution, which could limit its heat dispersion somewhat. Also, while it is portable, the weight may be a consideration for some users who need to move it frequently. This heater excels in energy efficiency and safety, making it a dependable choice for RV owners or anyone needing a portable heating solution.

The Heatstar 30000 Btu Vent Free Radiant Propane Heater is a solid choice for those needing a portable heating solution. 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. One standout feature is its top-mounted adjustable thermostat, which allows you to control the heat output with ease. Additionally, the battery-operated electronic ignition makes it simple to start without fumbling for matches or lighters.

The heater is flexible in terms of placement, as it can be wall-mounted or used freestanding, thanks to the included feet kit. 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.
