  • We used the SunFire radiant heater last winter in -20 degree cold working on harvesting parts from salvaged cars outside in the Wisconsin winter. The heater worked great! Always started and ran with no problems. We pointed the heater at a pile of scrap tires that were frozen in a pile of snow and ice. Within minutes, we could easily remove the tires from the pile and relocate them to another area of the yard. We love the portability of the SunFire, once when our shop heater ran out of fuel, we moved the heater into the shop and we could continue working without a problem. The work space was actually warmer than when we were using our regular heater.

  • 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.
