Patio heaters are devices that provide heat to outdoor spaces, making it pleasant to stay on the terrace even in cooler weather. Examples include electric heaters, which are easy to use and safe, and gas heaters, which provide efficient and fast heating. Patio heaters can have adjustable heat output, a timer and safety features such as fall protection. They are ideal for outdoor spaces such as patios, balconies and garden decks, where users want to extend their time outdoors all year round.
