The HUUM CORE Sauna Heater is built to reflect the personality of its owner while providing exceptional performance and luxurious steam with a modern, refined look.
Crafted in Estonia where sauna is a way of life, the HUUM CORE BK/ST is constructed from stainless steel with different inlay finishes to choose from. The unit arrives without a casing for easy customization with ceramic tiles, stone, glass or wood to personalize the heater and make it your own. Available in a variety of power ratings to suit a wide array of sauna sizes, the CORE thrives in tight spaces where users can benefit from the heater’s small footprint and minimal safety distances. This clever design allows endless choices for placement, including the option to embed the heater within the sauna bench.
The CORE will swiftly heat the sauna room while you confidently ladle water upon the sauna stone surface to generate an abundance of steam. Pair the unit with a UKU Control for total command of your powerful sauna heater system.
Backed by a 3-year warranty for private use, the HUUM CORE BK/ST Sauna Heater is an embodiment of pure Nordic design, showcasing versatile functionality and durability while providing long-lasting relaxation.
The HUUM CORE Sauna Heater offers flexibility and style with its contemporary black metal exterior design. This sleek and powerful unit is engineered for sauna rooms up to 566 cubic feet (CF).
- 6.5kW - For sauna rooms from 177 to 318 cubic feet
- 9kW - For sauna rooms from 283 to 460 cubic feet
- 10.5kW - For sauna rooms from 354 to 566 cubic feet
Heater For Modern Home Saunas
![]() STEEL electric sauna heater has been developed for contemporary apartment saunas. Its small dimensions and powerful construction provide a stylish supplement to the interior. The sauna heater is compatible with the UKU sauna control system, which enables you to heat the sauna irrespective of where you are. The optimized construction of the STEEL sauna heater means small safety distances. Its internal air tunnel ensures effective air flow and expedites sauna heating by 25%. In addition, it prolongs the useful life of the heating elements. According to the experts, you’ll need 50 kg of sauna stones for mild steam. STEEL electric sauna heater holds as much as 150 kg of stones, and the wall-mountable STEEL Mini fits 60 kg of sauna stones. ![]() |
CORE sauna heater was born to offer alternatives
![]() Development of CORE sauna heater was centered on freedom of choice. Discussions with sauna fans and collaboration partners across the world revealed the desire for a sauna heater that would convey the personality of its owner. We played around with the thought, and switched to product development. We created an efficient sauna heater that does not require massive safety distances. It is therefore also suitable for small apartment saunas. In addition, the CORE electric sauna heater can be completely embedded into the sauna bench. Each sauna has its own character, and this applies to CORE sauna heaters as well. Its finishing touch may be based on wood, stone, ceramics or even glass. However, we did not allow any cut-downs on the steam – it is still pleasantly mild. |
