Kaarna
The Tulikivi Kaarna electric sauna heater blends modern style with Finnish craftsmanship. Made with genuine Finnish soapstone, it retains heat beautifully and releases it gradually and evenly, creating a soft, long-lasting steam that makes for a comfortable sauna experience.
The Tulikivi Kaarna is thoughtfully designed with a convenient height adjustment feature and small safety clearances. Its soapstone surface has a relatively low surface temperature, making it comfortable to touch even as the sauna reaches high temperatures. This makes it easy to integrate into a range of sauna spaces while providing a practical choice for family-friendly sauna use.
The Tulikivi Kaarna holds up to 30kg of Tulikivi Sauna Stones, creating a soft and comfortably humid heat. It is designed for use with the Tulikivi Touch Controller, giving you precise control over your sauna experience.

FAQs
Have a question ? We are here to help.
Can I install a sauna in a small space or apartment?
Certainly! We have a number of heaters that are perfect for smaller sauna rooms like the
Core and Drop heaters from Huum, or the Routa heater from Tulikivi.
Probably the most important thing to consider when choosing a heater where space is a premium is the heater’s safety distance, or how far it needs to be kept from the wall.
In order to maximise the space you have for people in a smaller sauna you may wish to install a heat deflector on your heater to which halves the safety distance required on that side of the heater.
How do I choose the right size heater?
The size of the heater should be chosen based on the sauna room size and insulation. Choosing the right size is important. If the heater is too small, it will heat the sauna too slowly, it won’t provide enough steam, and it might burn out quicker. It is better to opt for a slightly too powerful heater with a thermostat. You need 1 kW of power to heat 1 m³ of the sauna room as a rule of thumb. The second important thing to consider is how the sauna room is insulated. If there are any uninsulated brick, tile, glass or log walls in the sauna room. An additional 1.5 m³ for each m² of such wall should be added to the sauna room size calculation. You can use our sauna calculator to find out the volume of your sauna room. If in doubt, please contact our friendly team, and we will help you find the perfect heater for your sauna!
What is the lifespan of the equipment?
With proper care, a good-quality sauna can last you 10–20 years, easy. Heaters and electrical components might need replacing
sooner depending on use, but overall they’re built to go the distance.
