We have updated two of our most popular sauna heater models, Teno and Kalla, to better meet the needs of modern sauna users. Sauna heaters are playing an increasingly important role as interior design elements, and alongside energy efficiency and control options, appearance and space utilization have become key considerations.
Teno 2.0 and Kalla 2.0 bring clean-lined design, energy efficiency, and intelligent control solutions to any sauna, making sauna bathing easier, safer, and more enjoyable.
Style and efficiency for your sauna
The renewed, modern appearance and carefully considered details make the heaters a natural part of the sauna interior. The air guide has been moved inside the heater, the outer casing perforation has been redesigned, and the logo on the front panel has been updated. The result is a more minimal and refined overall look that blends beautifully into the sauna. Thanks to improved technical solutions, heating is faster and electricity consumption remains under control, making everyday use more comfortable and cost-efficient.
Teno 2.0 – an efficient wall-mounted heater
Teno 2.0 is a wall-mounted heater that heats up quickly and uses electricity efficiently. Spiral heating elements enhance heat transfer and shorten heating time, while the large 40 kg stone capacity ensures that the steam is evenly distributed from floor level to ceiling.
Teno is available with three control options: traditional mechanical switches, the intelligent E2 controller, and the E2W WiFi solution, which enables remote control via a mobile device.

Kalla 2.0 – a compact option for smaller saunas
Kalla 2.0 is a space-saving floor-standing heater designed especially for smaller saunas. It stands on its own legs, so it does not put any load on the wall structures, and thanks to its small safety distances it can be installed directly against a panelled wall or integrated into the benches. Kalla’s clean and minimalist design makes it a natural, elegant addition to the sauna space.
Control options include E2 and E2W WiFi.

Smart control systems make going to sauna easy and safe
The perforated outer casing of the renewed heaters adds versatility to the sauna experience. The character of the steam can be adjusted by throwing water on different parts of the heater: water thrown on the sides creates softer steam, while pouring water on top produces a more intense result.
Mondex E2 models learn your sauna’s heating needs and automatically regulate temperature to prevent unnecessary overheating. The E2W WiFi solution takes convenience further: you can control the heater remotely, monitor electricity consumption, and receive notifications, for example when it is time to replace the stones. The included door sensor enhances safety by preventing remote start if the door is opened when the sauna is set to standby mode.
A well-functioning, stylish sauna heater is more than just a heat source. The renewed Teno 2.0 and Kalla 2.0 make the sauna more comfortable, simplify everyday life, and add a touch of luxury to an ordinary sauna evening. And with remote control, you can switch the heater on while heading home, so the sauna is ready when you arrive.
