HUUM Electric Sauna Heaters

What makes the steam from a HUUM electric heater so special?

It all comes down to the stones. HUUM heaters are engineered with a massive stone capacity, far exceeding most standard electric heaters. This large thermal mass allows them to produce an incredibly soft, rich, and prolonged steam—or löyly—that many sauna enthusiasts consider the best in the world. It’s a gentler, more humid heat that deeply envelops you.

What size HUUM electric heater do I need?

Choosing the right size is critical for performance. The power you need (measured in kW) is based on your sauna's volume. To get a precise recommendation for your specific room, our Sauna Heater Size Calculator is the best tool for the job. It will ensure you get a perfectly matched heater for efficient heat-up times.

Do all HUUM electric heaters require a separate controller?

Yes, and that's a key part of their beautiful design. To maintain their sleek, minimalist aesthetic, all HUUM electric models are operated with a separate, wall-mounted controller. The HUUM UKU controller is the most popular choice, offering a stylish interface and WiFi capabilities for remote preheating from your phone.
