Because the S25 offers a lower radiant heat output than many other natural gas patio heaters, it can be placed in patios with a limited ceiling clearance. When properly integrated into your patio's design, the S25 can increase the comfort level five to ten degrees Fahrenheit outdoors, depending on wind and weather conditions. For easy operation, the Sunpak S25 infrared patio heater also utilizes a fully automatic On/Off control system. Included is a 24 VAC spark ignition system as well as flame monitoring through flame rectification.
Please note that this heater is not designed for indoor residential use and requires a continuous supply of fresh air and proper ventilation. The S25 natural gas infrared heater is also available in stainless steel.
