10 Best Propane Heaters 2025 in the United States

The Hykolity Pyramid Patio Heater is designed for outdoor use, offering a stylish and functional option for heating your patio, backyard, or garden. With a heating capacity of 48,000 BTU, it effectively warms up an outdoor space, making it ideal for gatherings on cool evenings. The heater runs for about 8-10 hours on a standard 20 lb propane tank, providing long-lasting warmth that enhances your outdoor experience. Its modern design, featuring a clear glass tube that showcases the flame, adds a decorative touch to your outdoor area.

Portability is a strong point of this heater, as it comes with detachable wheels that allow for easy movement to different locations, which is perfect for those who may want to reposition it based on their needs. Additionally, the built-in control valve enables you to adjust the heat output to match your comfort level.

Safety is also prioritized with features like an anti-tilt shut-off device, which automatically turns off the heater if it tilts over 45 degrees, ensuring peace of mind during use. The included waterproof cover protects the unit from the elements when not in use, extending its lifespan. However, the heater is designed solely for outdoor use, so it won't be suitable for indoor applications. Additionally, the propane tank is not included, which means you'll need to purchase that separately. While the warranty and customer service promise is reassuring, potential buyers should be mindful of maintaining the heater properly to ensure it functions safely and effectively over time.

Its radiant heating design provides 540° coverage, effectively warming both people and objects in its vicinity, which is a significant advantage for larger gatherings or events.

Safety is a strong point with the MH540T, featuring a tip-over safety shut-off that automatically turns the heater off if it gets knocked over.

Furthermore, the soft nose POL connection ensures a secure, leak-free operation with propane tanks, enhancing reliability during use.

On the portability front, weighing just 5.5 pounds, the heater is easy to transport, making it perfect for outdoor enthusiasts. The push-button TE valve allows for quick ignition, and there's also a manual lighting option for added convenience. However, there are some limitations to consider. The heater is designed exclusively for outdoor use, which may not meet the needs of those looking for indoor heating solutions. Additionally, while it effectively covers an area of around 100 square feet, larger spaces may require multiple units or a more powerful model. Users will also need to ensure proper ventilation when using propane outdoors, as with any gas appliance. The Mr. Heater MH540T is a reliable and efficient choice for anyone needing portable outdoor heating, with safety features and ease of use that cater well to recreational activities, though it’s not suitable for indoor applications.

Safety is a significant strength of this model, featuring auto shut-off mechanisms if tipped over, when the pilot light goes out, or if it detects low oxygen levels, providing peace of mind during use. Portability is another advantage, as it’s designed to be easily moved around. However, the heater can shut off when used at altitudes above 7,000 feet, which might be a limitation for users in high-altitude regions.

Additionally, due to recent changes, some models no longer include a fan, which might affect heat distribution for those versions. The heater connects to standard propane tanks, but it’s important to note that unauthorized accessories are prohibited and could void the warranty. This heater is particularly beneficial for users who require a reliable, portable heating solution with strong safety features.
