The Commercial Patio Heaters are in a class by themselves, and are the most powerful patio heaters around. They put out a whopping 46,000 BTU’s, with a heat range of around 18 feet. These are also heavy duty heaters, so they’re durable and will last a very long time under normal use. They come in some beautiful finishes, like the Copper, Stainless Steel, Mocha, and Hammer Tone Bronze finishes.
