Designed to warm outdoor spaces, patio heaters come in two basic types. The first (and usually the cheapest) are electricity-powered options. Whether shaped like a strip and oriented parallel to the ground or in a chameleon-like tower form, they’re odor- and upkeep-free, making them great for semi-enclosed areas like lanais, sunrooms, and pergolas. They will, however, keep you anchored to your nearest outlet and rarely handle inclement weather well longterm. The second (and more powerful) are propane-powered tower units. They’re movable (some easier than others) and work better for heating large areas or customizable layouts. However, they often come with a correspondingly larger price tag and the need for propane tanks, which always seem to run out just when you want to use them most.
