SupremeSchwank Single Stage heater is a sleek and durable infrared gas patio heater with an attractive black finish. Fueled by propane or natural gas and 23,000 and 35,000 BTU output, it is a highly efficient heating solution. Combine all that with wireless control options, you get a heater that is easy to use and is sure to add warmth to any commercial or residential outdoor space.

SupremeSchwank heaters allow you the freedom of mounting your heater the way you want. With a variety of mounting options, this heater is great for any patio setting. Choose a mounting option based on how you want your heaters to be installed.

This heater has one heat setting which can be controlled using the optional wireless receiver and remote. If you wish to control heaters in multiple zones in one place, the patioPanel is a better control option.

Both the 23,000 and 35,000 BTU models can be used for indoor and outdoor commercial use. For residences, it is best to install these gas heaters outdoors.

*Note: "Mounting angles and distances are suggested to ensure comfort and are subject to site and design conditions. Install multiple heaters to keep large outdoor areas warm."
