Patio heaters help keep outdoor spaces warm, and they can even be used to create a cozy ambiance for parties and gatherings. They’re available in a range of styles, from freestanding to wall-mounted units, and they’re typically powered by natural gas, liquid propane or electricity. The fuel source and power type you choose will play a large role in the installation requirements, maintenance costs and heat output of your patio heater.
If you’re looking for a patio heater that can be easily moved from place to place, a gas model might be the best option for you. Using liquid propane (LP), these models provide ample warmth for an average of 10 hours with a single 20-lb tank.
The heat output of a patio heater is measured in British thermal units (Btu), and it’s an important factor when deciding on the right unit for your space. To estimate the Btu required to heat a given space, multiply its square footage by 20, and then divide that number by 100.
When considering a propane or gas patio heater, look for models that have an oxygen depletion sensor to prevent unsafe conditions such as suffocation or carbon monoxide buildup. You’ll also want to make sure the proper safety clearance is maintained between your heater and any flammable objects or structures.
Finally, check the patio heater’s warranty and safety certifications to ensure it meets your needs for quality, durability and usability. And don’t forget to buy a fire extinguisher and read the manufacturer’s instructions for safe use.
