Because the S25 S ffers 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 S can increase the comfort level five to ten degrees Fahrenheit outdoors, depending on wind and weather conditions. For easy operation, the Sunpak S25 S 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.
