HUUM DROP 7.5 (7.5 kW) Electric Sauna Heater

Elevate your sauna with the award-winning HUUM DROP 7.5, a high-performance electric heater inspired by the purest element in nature—a water drop. This sculptural, wall-mounted heater combines modern Estonian design with exceptional engineering, softening the angular lines of a traditional sauna while providing a superior thermal experience. Recognized with a Red Dot Award honorable mention, the DROP 7.5 is as much a piece of art as it is a powerful spa appliance.

Despite its compact, space-saving design, the DROP 7.5 features an extraordinary stone capacity that rival most wood-burning stoves, ensuring soft, long-lasting steam (Loyly).

Sculptural Space-Saving Design

The DROP 7.5 is engineered specifically for wall mounting, freeing up valuable floor space in your sauna. Its unique rounded silhouette is not only aesthetically pleasing but functional, allowing for efficient heat radiation from all sides. This design makes it an ideal choice for custom-built residential saunas where style and performance must coexist.

Superior Thermal Mass & Steam

The HUUM DROP 7.5 holds a massive 132 lbs (60 kg) of stones, providing a thermal mass far exceeding standard wall-mounted heaters. This high stone capacity ensures that the heater maintains a consistent climate and produces a deep, rich steam when water is poured over the rocks. The open cage design allows air to circulate through the stone pile, resulting in a milder and more natural heat.

Durable Stainless Steel Craftsmanship

Each HUUM heater is precision-crafted in Estonia using high-grade stainless steel for maximum durability and corrosion resistance. The elegant cage structure is designed to hold the stones securely while allowing the heating elements to radiate warmth directly into the room.

Easy Operation & Smart Integration

Designed for the modern home, the DROP 7.5 operates on a standard 240V 1-phase connection. It is intended to be paired with an external control system, such as the HUUM UKU series, which allows for precise temperature management. With the UKU Wi-Fi option, you can preheat your sauna directly from your smartphone via the HUUM mobile app, ensuring your sanctuary is ready exactly when you are.
