Description
Kaarna Electric Sauna Heater - Tulikivi Kevo Collection
*stones, contactor box & controller to be purchased separately*
This heater requires up to 35kg sauna stones. We recommend using 2 x 20kg boxes of 5-10cm Olivine Diabase or Vulcanite Sauna Stones for optimal performance. The L version (12.8kW and 15.3kW) requires 50kg of sauna stones.
Kaarna Electric Sauna Heater is compatible with the Tulikivi Complete Wi-Fi Control System and can also be used HUUM UKU Local Controller or HUUM UKU Wi-Fi Controller.
The timeless Kaarna electric sauna heater from Tulikivi Kevo Collection combines top-notch design, natural Finnish soapstone and advanced technology. The soapstone encasing efficiently retains heat and releases it evenly, creating a long-lasting and pleasant steam in the sauna. The Kaarna heater features unique height adjustment and small safety distances. The model is available in two soapstone finishes: A lighter-coloured Classic and the darker Nobile.
Kaarna electric heater is the perfect choice for a modern-day home sauna or a public sauna.
