The heaters provided great warmth and were quiet and odorless, keeping the guests very comfortable throughout the chilly fall night.

  • We have a large drafty fabrication space where we manufacture our steel storage tanks. The Minnesota winters can be very cold and windy. Last winter we replaced our old propane space heaters with the SunFire radiant heaters.  My guys loved them! Quiet, without the odor of the propane heaters and kept the work space very comfortable. We are looking forward to using them again this season.
