Our electric sauna heaters or Sauna Stoves features an improved "heat release system" that allows virtually all of the heat to be circulated into the center of the room, keeping the sauna heater and the elements much cooler, resulting in 20 or 25 year life spans of the elements. The built-in heat deflectors assist in moving the heat to the centre of the sauna room to benefit the bathers and away from the ceiling directly above the sauna heater.
