Whether you need to heat your warehouse, garage, or other hard-to-heat spaces, the SunStar SIS Series infrared heaters provide both the fuel efficiency of radiant heat and the installation flexibility you need.

SunStar infrared tube heaters are ideal for complete building heat or spot heating needs. The best applications are those where doors open and close frequently and in buildings where ceiling heights are above ten feet. The flexible SunStar infrared heating system can be designed to meet any commercial or industrial heating needs.

The minimum mounting heights are shown for human comfort and uniform energy distribution for complete building applications. Mount heaters as high as possible. CSA certified. This product has 5 year limited warranty on tubes and 1 year limited warranty on unit. This product is made in USA.

Note: Since straight tubes are always hotter at the burner end than at the exhaust end, always observe the minimum recommended mounting heights shown on the specification sheet for greatest human comfort. Use SIU series instead of SIS series for spot heating applications.
