HUUM Cliff Sauna Heaters

What is the main advantage of the Cliff heater?

Its biggest advantage is its incredibly space-efficient design. The Cliff requires significantly smaller safety distances from wooden surfaces than almost any other heater. This allows you to maximize your bench space and create a more open, comfortable feeling, making it the ideal choice for compact or narrow sauna rooms.

How does it compare to the HUUM Steel model?

Both are fantastic space-savers. Think of the HUUM Steel as the versatile engineer, available in multiple sizes for wall or floor mounting. The Cliff is the minimalist specialist—designed exclusively for wall-mounting to be as slim and unobtrusive as possible. If maximizing floor space is your absolute top priority, the Cliff is the winner.

What size sauna is it designed for?

The Cliff series is perfect for small to medium-sized home saunas. It's available in a compact 3.5kW version for intimate spaces, as well as more powerful 6kW and 9kW options for larger rooms. To get a precise recommendation, our official heater size calculator is the best tool for the job.

Is it compatible with UKU controllers?

Absolutely. The Cliff heater is designed to work seamlessly with the full range of sleek HUUM UKU controllers, including the WiFi-enabled models that allow you to preheat your sauna from anywhere. You get the full, premium tech experience.
