Finnleo Sauna Heaters

For special comfort with soft, even heat...
Feel the reviving spirit of Finnleo saunas. Finnleo heaters are the heart and soul of the sauna. With exclusive heater design, Finnleo puts two times more rocks in direct contact with the elements. The result is special comfort: a soft steam and soft, even heat rising from the rocks, not the metal, avoiding the harsh "electric toaster" feel. Open air flow design ensures quick, effective heating with efficient energy use.Sauna Heaters

All Finnleo heaters and controls are tested and listed for secure, trustworthy use and superior quality. The heater's triple-wall structure maintains minimal surface temperatures for safety and increased user pleasure. Stainless steel shell and elements ensure continuing high performance. And the heat shield's baked-on enamel finish complements any sauna (optional stainless steel exterior available). Quality materials and expert engineering make Finnleo a sensational sauna experience above all others.

Finnleo Heat Storing Sauna Heaters

Finnleo's "SaunaTime" and "Saunatonttu" heaters are a combination of a thousand years old tradition and the best of modern technology. These magnificent heat-storing heaters allow the sauna bather to enjoy sauna at any time without preheating. Simply open the lid, sit or lie down, sprinkle water on the preheated rocks...and enjoy.

The secret of the Finnleo heat-storing heaters is in the constant heat retained by the large quantity of rocks (200 lbs.) within the super-insulated heater. Space age insulation technology made this innovation possible--super heated rocks inside and cool surface temperature outside. The temperature of the rocks is maintained by low wattage elements that can be switched to 100 watts, 200 watts or 300 watts depending on the amount of heat and steam desired by the user. If more heat is desired or if multiple users will use the sauna, the booster element can be turned on for extra healing power.


Original EverReady Heater Original Heat Storing SaunaTime Heater
Originally developed and patented by Saunatec/Finnleo in the early 90’s, this heater is considered the most dramatic sauna heater development ever. As the name "SaunaTime" suggests, this sauna heater is ready for use at all times. Developed to recreate the sauna conditions of ancient wood-burning saunas (lower temperatures, huge rock mass, lots of humidity), its most notable benefit is the soft, moist steam, which comes from the depths of the extra large rock compartment.

  • 34" H x 15" W x 19" D
  • Separate handheld control mounted inside the sauna
  • Low wattage range ("lways on" mode): 135 W, 225 W, or 360 W
  • Booster element power range: 4.4 kW and 5.8 kW
