10 Best Outdoor Heaters 2026 in the United States

The Mr. Heater MH9BX is a compact, portable propane heater designed for outdoor spaces up to 225 square feet, making it a good option for patios or camping. With a heat output ranging from 4,000 to 9,000 BTUs, it provides adjustable warmth suitable for small to medium outdoor areas. Its radiant burner efficiently directs heat outward, which helps warm you directly rather than heating the air. The heater runs on a propane tank (sold separately) and can operate for about 5.6 hours at the lowest setting, which is convenient for longer outdoor use.

This model is lightweight at just over 7 pounds and features a fold-down handle for easy transport, enhancing its portability. Safety is a strong point here: it automatically shuts off if tipped over, if the pilot light extinguishes, or if oxygen levels drop too low, helping prevent accidents. The design is practical with a bright red color and sturdy steel construction, though it’s more functional than stylish.

One limitation is that it might shut off at altitudes above 7,000 feet, which could be a concern if you live or camp in mountainous areas. Also, using any unauthorized accessories will void the warranty and could be dangerous. This heater is approved for outdoor use but is not intended as a primary indoor heater. To conclude, the Mr. Heater MH9BX offers a reliable and safe option for those needing a portable, propane-fueled outdoor heater that balances heating power with user-friendly features.

The Dr Infrared Heater DR-238 is an electric infrared heater designed for both indoor and outdoor use, making it a versatile choice if you want one heater for your patio, garage, or even indoor spaces. It runs on standard 120V electricity and offers three heat settings (900W, 1200W, and 1500W), providing quick and clean warmth without any odors. This type of heater uses radiant heat, which warms objects and people directly rather than heating the air, so it can be quite effective in outdoor settings.

One of its strengths is its weatherproof aluminum build and IP55 rating, which means it resists dust and water splashes, suitable for patios or decks. It comes with mounting brackets for wall or ceiling installation, so it’s less portable but great if you want a fixed, stable heat source. The heater is relatively lightweight at 8 pounds and easy to operate with a remote control.

As an electric heater, it requires access to a power outlet, which might limit placement options outdoors compared to fuel-based heaters like propane models. The design is sleek and modern in black, which fits well in many outdoor or restaurant environments. It has standard safety features expected from electric heaters. If you want an efficient, quiet, and clean heater permanently mounted on your patio or deck for moderate outdoor warmth, the Dr Infrared DR-238 is a solid and reliable option.

The Original 540-Degree Tank Top Radiant Propane Heater is a solid choice if you need a portable, efficient outdoor heater. It offers a high heat output of up to 45,000 BTUs, which can comfortably warm an area of about 100 square feet—perfect for small patios or outdoor gatherings. It runs on a 20 lb propane tank, which is convenient since the heater mounts directly on top, making it easy to move around. The heater has three heat settings (high, medium, low), allowing some control over the warmth and fuel use. A useful safety feature is the tip-over shut-off switch, helping prevent accidents if the unit gets knocked over.

The design is compact and practical, with a polished finish that looks good without being flashy. It also has an adjustable tilt head so you can direct the heat where you want it. One downside is that it’s strictly for outdoor use—no indoor heating here. Also, while the heater is lightweight and portable, it relies entirely on propane tanks, so you’ll need to keep spare tanks handy for longer use. If you’re looking for a quiet, effective outdoor heater that’s easy to set up and move, this model delivers well, especially for spaces around 100 square feet.
