Rock heaters are the most traditional way of heating your sauna. Rock heaters have electric heater elements that heat your sauna rocks. The sauna room is heated through transfer of that heat into the air from the sauna rocks. The user can create a huge thermal blast by pouring water onto the sauna rocks.


"Smooth Heat" Ultra efficient Heaters. Our Ultra line 3-stage sauna heaters are extremely efficient. Each heater consists of 3 heating elements. Each element is fed 1/3 of the total wattage of the heater. When your sauna is cold, all 3 heating elements turn on full power. When your sauna begins to reach its set temperature, one of the heating elements is powered down to save energy. When your sauna reaches its set temperature, the second heating element shuts off, but the center coil remains on, so your sauna STAYS at the temperature that you set it at. These heaters come in either digital or analog. Analog heaters have built in controls and a 9 hour delay timer built right into the sauna heater! Digital heaters allow for you to add a deluxe, external digital controller. All Ultra 3 stage heaters are fully constructed of stainless steel inside and out, and come with a polished stainless steel exterior finish.
