The best propane patio heater for your space: our guide

There are two types of gas-powered heaters: propane and natural gas. Propane heaters are generally more portable and versatile since the fuel is stored in refillable propane tanks. These tanks are tucked away within the heater, and tank refills are readily available at gas stations, convenience stores, supermarkets, and hardware stores. Natural gas heaters, on the other hand, require a permanent gas line connection, limiting their placement. Natural gas heaters are often used in commercial spaces.

Natural gas is typically cheaper than propane per BTU, but the installation cost of running a gas line can be significant. Propane heaters have lower upfront costs since you only need to purchase the heater and fuel tanks.

Patio heaters are rated by their British Thermal Unit (BTU) output, which determines the area they can effectively heat. Generally, a 5,000 BTU heater will warm up to 150 square feet, while a 2,000 square foot area requires around 34,000 BTUs. However, several factors influence the actual heat coverage. Lower ambient temperatures require higher BTU output to achieve comfortable conditions. Covered patios also retain heat better than open spaces.

As a rule of thumb, one freestanding patio heater can warm a 20-foot diameter circle in an open area but only around 10 feet in windy conditions. For more information on heater coverage, consult our Patio Heater Buying Guide.

When heating larger outdoor spaces, it's important to calculate the total BTU output needed and determine the optimal placement of multiple heaters for even heat distribution. A general rule of thumb is to have 20 BTUs of heat output per square foot of space.

Angling heaters towards the desired heating area can also improve heat distribution. For very large spaces over 1,500 square feet, plan to have one freestanding heater per 1,500 square foot section.

Mounted patio heaters are ideal for locations without overhead structures or coverings, as they can provide heat without taking up any floor space. They are a great choice if you want to maximize space and have a permanent heating solution.

Freestanding heaters offer more flexibility, as they can be easily moved to accommodate different setups as needed. Freestanding heaters are a great choice for outdoor spaces of all sizes and can provide heat at lower levels.

To ensure your patio heater will work properly and last for years to come, it’s important to purchase a patio heater made by a reputable and trusted brand. AuthenTEAK only carries patio heaters from reliable outdoor brands that prioritize high-quality materials and manufacturing processes. Some of the best propane patio heater brands—all of which produce efficient infrared heat— include:

• Bromic - Bromic Heating offers premium infrared patio heaters for commercial and residential applications. All Bromic patio heaters are designed and engineered in-house with patented Smart-Heat™ technology. By emitting a form of electromagnetic radiation, Bromic’s infrared radiant heaters warm objects directly rather than the air, similar to the experience of the sun warming your skin. This offers superior heating performance and higher resistance to wind, making them ideal for outdoor spaces or areas with increased airflow. This heating type is also considered more sustainable, as these energy-efficient infrared heaters heat up quickly and maintain warmth without excessive energy consumption.
• Patio Comfort - Patio Comfort’s outdoor infrared patio heaters are designed to provide clean and efficient infrared radiant heat. Patio Comfort heaters are available in a wide variety of colors and mounting options. A match-free ignition, durable aluminum frame, and 100% safety control make these heaters an ideal solution for a variety of outdoor applications.
• Sunglo - The original Sun-Glo patio heater was designed in 1961 by Edwin J. Cowan, a leading U.S. infrared heating appliance engineer. Since then, the Sun-Glo heater’s design has been modified for a wide variety of uses. The Sun-Glo heater is now found in fine restaurants, covered and outdoor pools, spas, greenhouses, dining areas, and residential patios. Sun-Glo’s durable stainless steel patio heaters feature modern silhouettes and are available in black and silver finishes.
