10 Best Portable Propane Heater 2025 in the United States

The Mr. Heater MH540T is a strong choice if you're looking for a portable propane heater to keep outdoor spaces warm. It offers three heat levels ranging from 30,000 to 45,000 BTUs, which is powerful enough to warm up an area about 100 square feet. The unique 540-degree radiant coverage with a 360° burner and adjustable tilt means it spreads heat evenly around you, not just in one direction. Its design is compact and lightweight at 5.5 pounds, making it easy to place on top of a propane tank and move around as needed. Safety is well-covered with a tip-over shut-off that stops the heater if it falls, reducing risk of accidents. Ignition is simple with a push-button starter, but you can also light it manually if needed. The connection to the propane tank is secure and leak-free thanks to the soft nose POL fitting.

This heater is meant strictly for outdoor use, so it’s not suitable for indoor spaces. While it is fairly quiet and easy to operate, it does require a standard propane tank to work, so you’ll need to have that ready. Its size and polished finish make it a practical and decent-looking option for activities like camping, tailgating, or porch heating. The heater balances good heat output, safety, and portability for outdoor use, though it’s limited to spaces where propane tanks are allowed and outdoor conditions.

The Mr. Heater F242010 MH4GC 4000 BTU Golf Cart Heater is designed to keep you warm during chilly golf outings. With a BTU rating of 4,000, it provides sufficient heat for a small space like a golf cart, and it can run for up to 5.5 hours on a single 1 lb. propane cylinder, which is efficient for extended use. The heater is highly portable, featuring an ergonomic handle and a cup holder adapter to fit most golf carts, making it easy to transport and set up.

Safety is a priority with this heater, incorporating an oxygen depletion sensor (ODS) and a tip-over safety switch to prevent accidents, even on bumpy paths. The wind-resistant burner ensures that the heater remains effective even in windy conditions, and the one-button Piezo igniter simplifies startup without needing matches or electricity. However, it should be noted that this heater is designed specifically for outdoor use and is tailored to fit golf carts, which may limit its versatility for other applications.

Its design is compact and user-friendly, but it connects directly to a 1 lb. propane cylinder, which is not included, so users need to purchase fuel separately. This heater is ideal for golfers wanting a reliable, easy-to-use source of warmth during their game, but those looking for a more general-purpose heater might need to consider other options.

The Mr. Heater MH9BX is a versatile portable propane heater ideal for small spaces up to 225 square feet, making it suited for outdoor activities like camping or patio heating. Its BTU rating ranges from 4,000 to 9,000, offering flexibility in heat output to match varying needs. The heater’s clean-burning efficiency and nearly 100-percent energy utilization are excellent, providing warmth without unnecessary fuel waste. Portability is a notable strength, as it's lightweight at 9.5 pounds and features a fold-down handle for easy transport. The design, with a swivel-out regulator for easy propane tank connection, adds to its user-friendly nature.

Safety is a highlight, with automatic shut-off features for tip-overs, extinguished pilot lights, or when low oxygen levels are detected, enhancing peace of mind during use. However, it’s important to note that the heater may shut off at altitudes over 7,000 feet, which could be a limitation for high-altitude camping.

Ignition is straightforward and does not require batteries, contributing to ease of use. Fuel consumption is reasonable with a runtime of 5.6 hours at minimum BTU, though users should be mindful to bring sufficient propane for extended use, as the tank is not included.

While its robust safety features and portability are appealing, users should avoid unauthorized accessories to maintain warranty coverage and ensure safety. The heater is designed for both indoor and outdoor use, but the official recommendation is for outdoor use, likely due to ventilation requirements. This heater is an excellent choice for those needing a portable, efficient, and safe heating solution for outdoor spaces, though care should be taken when using it at high altitudes.
