Outdoor heaters are heating appliances designed to provide warmth and comfort to outdoor spaces. They come in a variety of types, sizes, and styles, and are typically powered by propane or natural gas, although some models may also be electrically powered.

Outdoor heaters can be freestanding, mounted on a wall or ceiling, or tabletop models. Some models may also include features like wheels for easy portability, adjustable heat settings, and safety shut-off switches.

One common type of outdoor heater is the patio heater, which is typically freestanding and features a tall pole with a heating element at the top. Patio heaters can come in various sizes and styles, and can provide heat to a large area, making them ideal for outdoor dining or seating areas.

Other types of outdoor heaters include infrared heaters, which provide heat by radiating infrared light, and outdoor fireplaces or fire pits, which provide both warmth and ambiance.

When using outdoor heaters, it's important to follow all safety precautions, including ensuring that the heater is stable and secure, keeping it away from flammable materials, and never leaving it unattended while in use. It's also important to make sure the heater is designed for outdoor use and is properly ventilated to avoid the risk of carbon monoxide poisoning.
