Tulikivi’s new electric sauna heater collection meets U.S. ETL requirements

Tulikivi Corporation’s new-generation electric sauna heater collection meets the ETL requirements for the US market. Compliance with the requirements covers Tulikivi’s Kaarna, Pyry and Usva electric sauna heaters as well as the WiFi control system.

The products have been tested in accordance with the new UL 60335-2-53:2025 safety standard for sauna heaters, published in summer 2025. Meeting the ETL requirements enables the commercial launch of the collection in the United States and supports Tulikivi’s growth targets for its international sauna business.

Tulikivi’s electric sauna heater collection combines Finnish sauna tradition, modern design and Tulikivi’s extensive experience in heat-retaining materials. Key features of the collection include safe surface temperatures, short safety distances and the opportunity to create an individual sauna experience. The collection uses soapstone, a material characteristic of Tulikivi, which enhances ease of use and supports a high-quality sauna experience.

“Meeting the ETL requirements and the requirements of the new UL standard for sauna heaters represents a significant milestone in the international growth of Tulikivi’s sauna business. It gives us access to the world’s largest sauna and wellness market and strengthens our opportunities to grow our business in North America,” says Heikki Vauhkonen, CEO of Tulikivi Corporation.

Tulikivi has begun marketing and distributing the collection in the United States in cooperation with local dealers and partners.
