10 Best Propane Heaters 2026 in the United States

The Mr. Heater MH9BX is a portable propane heater that offers a BTU rating ranging from 4,000 to 9,000, making it suitable for heating spaces up to 225 square feet. This makes it a good choice for small outdoor areas. One of its key strengths is its portability, featuring a fold-down handle and swivel-out regulator, which makes it easy to transport and set up.

It runs on propane tanks (not included) and can operate for up to 5.6 hours on the minimum BTU setting, which allows for extended use without frequent refueling. Safety is a notable feature of this heater, with an auto shut-off function that activates if the unit is tipped over, if the pilot light goes out, or if low oxygen levels are detected. This makes it a safer option for outdoor use.

However, it's important to note that the heater may shut off if used at altitudes over 7,000 feet, which could be a limitation for users in high-altitude locations. Additionally, the use of unauthorized accessories or attachments is prohibited and can void the warranty, which is something users should be mindful of. This heater does not require batteries and comes with a 1-year limited warranty. The construction of the heater includes steel, plastic, and nickel, enhancing its durability. Despite its strengths, it is designed for outdoor use only, limiting its versatility.

In summary, the Mr. Heater MH9BX is a reliable and efficient option for those seeking a portable heater for outdoor spaces, with strong safety features and good fuel efficiency, but it may not be suitable for high-altitude use or indoor applications.

The ProCom ML100TPA-B propane heater is a solid choice for heating small to medium indoor spaces like bedrooms, home offices, or living rooms. With a maximum output of 10,000 BTUs, it can comfortably warm areas up to 500 square feet, which is enough for typical rooms in most homes. Its infrared radiant burner provides a steady and direct heat source, making the warmth feel pleasant and efficient.

One advantage is its versatility in placement: it can be mounted on a wall or simply set on the floor using the included base feet. This slim and modern design fits well in many room styles without being bulky. Since it doesn’t require electricity to run, it’s useful during power outages or emergencies, adding to its convenience. Safety is addressed with an oxygen depletion sensor that immediately shuts off the heater if the air quality drops, and it has overheat protection to prevent accidents. The push-button ignition is simple to use and eliminates the need for matches or complicated setups.

The heater weighs about 15.5 pounds, making it somewhat portable though not extremely lightweight for frequent carrying. Because it’s ventless, it’s important to use it in well-ventilated areas to avoid indoor air quality issues. If you're looking for a reliable, easy-to-use propane heater for indoor spaces up to 500 sq. ft., especially where electricity may be limited, this model offers a good balance of safety, heat control, and design. For those needing more portability or detailed fuel efficiency information, exploring other options might be beneficial.

Safety is a strong point here, with features like an anti-tilt automatic shut-off and a burner screen guard that help prevent accidents while you enjoy the warmth.

The heat output is adjustable via a simple dial knob, letting you control how much heat you want, from low to high settings. It uses a standard 1-pound propane tank but can be connected to a larger 20-pound tank for longer use, though the extra regulator for this is not included. Its heating area is limited to about 30 square feet, so it’s best suited for smaller gatherings rather than large groups.

This heater is ideal if you want a safe, portable, and easy-to-use propane heater for modest outdoor spaces, but it might not be powerful enough for bigger areas or extended heating without additional accessories.
