Red Dot-Awarded Electric Sauna Heater

The drop electric sauna heater is inspired by the purest element of nature - water. The single-water-drop design gave the unit its organic, minimalist form. It comes in a curved stainless-steel casing, a recessed stone bed, and a compact wall-mounted profile that holds its own without overpowering the room. This design approach earned the Drop unit the prestigious Red Dot design award.

The 6kW model carries approximately 55kg of olivine diabase sauna stones to give you the perfect löyly — the burst of steam produced when water meets the surface. For those fitting larger sauna rooms, go for the Drop 9kW to deliver higher output.

UKU Control Unit — From Basic Panel to Wi-Fi App Control

Every HUUM Drop heater pairs with the UKU control unit. The base version can manage temperature, timer, and steam output from a clean wall panel. But the UKU Wi-Fi steps this up! It can connect to the HUUM mobile app, so you can control almost everything from your smartphone. All you need to do is set the heat remotely, arrive at a ready room, and adjust the temperature without leaving your seat.

For multi-heater setups or rooms requiring extended power distribution, the HUUM extension box handles the additional load without compromising the control system.

Why HUUM Heaters Stand Apart from Wood-Burning and Standard Electric Options

HUUM sauna heaters were designed to overcome the limitations of both traditional wood-burning heaters and generic electric stoves. While wood-burning heaters require time, fuel, and chimney infrastructure, HUUM heaters deliver authentic Finnish sauna heat with far less friction. The Drop 6kW in particular suits homeowners who want the authenticity of high stone capacity and soft steam without the complexity of a wood-burning stove.

Frequently Asked Questions

What size sauna room does the HUUM Drop 6kW suit?
The Drop 6kW is built for sauna rooms of approximately 8–10 m³. For larger volumes, the Drop 9kW handles greater cubic capacity. Room insulation and ceiling height also influence the required output.
Which controller works with the HUUM Drop 6kW?
The Drop 6kW pairs with the UKU control unit, either the standard or the Wi-Fi model. The UKU Wi-Fi version connects to the HUUM mobile app, allowing you to heat your sauna and manage settings directly from your smartphone.
What stones does the HUUM Drop use, and why does it matter?
HUUM Drop heaters use olivine diabase sauna stones, selected for heat retention and steam quality. A higher stone capacity means slower, softer, and more even heat release.
Does the Drop 6kW need a professional electrician for fitting?
Yes. A qualified electrician must install the Drop heater. The 1N electrical connection is analogous to a 3-phase setup, so correct circuit assessment is required before the unit goes in.
Is the HUUM Drop 6kW strong enough for my sauna?
The Drop 6kW is rated for saunas up to roughly 265 cubic feet. If your room runs larger, or if you're dealing with poor insulation or a glass-wall door, stepping up to the 9kW or 10.5kW version will give you more reliable heat recovery after pouring water on the stones.
