An outdoor heater, also known as a patio heater, is a device designed to provide warmth and comfort in outdoor spaces, such as patios, decks, gardens, or outdoor dining areas. These heaters are particularly useful during cooler evenings or colder seasons, allowing people to enjoy the outdoors while staying warm. Outdoor heaters come in various types, including propane, natural gas, electric, and infrared heaters. Propane and natural gas heaters typically have a fuel tank and a burner that radiates heat, while electric heaters use infrared technology to produce heat. Some outdoor heaters are freestanding, while others can be mounted on walls or ceilings. They are a popular addition to outdoor seating areas in restaurants, bars, hotels, and residential settings, providing a cozy and inviting atmosphere for guests to relax and socialize outdoors.
