HUUM CORE BK Aspen Electric Sauna Heater
The HUUM CORE BK Aspen Electric Sauna Heater is designed to complement a wide range of sauna interiors while delivering consistent heating performance in a refined, natural aesthetic. Crafted in Estonia, the CORE BK Aspen model features a stainless-steel structure with Aspen side panels and assorted inlay finishes to help it blend seamlessly with surrounding materials.
Offered in multiple power ratings to suit various room sizes, the CORE is engineered for compact spaces, benefiting from its small footprint and minimal safety distance requirements. Its adaptable form allows flexible placement, including the option to embed the heater within the sauna bench for an integrated look.
The stone housing is designed to circulate heat evenly, and users may pour water over the stones to generate steam as desired. When paired with a UKU Control (sold separately), the heater provides convenient operation and precise control settings.
Supported by a 3-year warranty for private use, the HUUM CORE BK Aspen Electric Sauna Heater combines Nordic design, customizable detailing, and durable construction for a clean, cohesive addition to your sauna.
