HUUM CORE Aspen CORE Series Sauna Heater, Aspen Wood Exterior, Up to 10.5kW

The HUUM CORE Aspen Sauna Heater is designed to complement the aesthetic of your sauna room while delivering exceptional performance and luxurious, enveloping steam. Blending natural materials with modern Nordic engineering, the CORE Aspen offers an upscale, contemporary look paired with powerful heating capability.

Crafted in Estonia—where sauna culture is deeply rooted—the CORE Aspen features a durable stainless-steel construction accented with pre-fitted aspen wood side panels and a selection of inlay finishes. The light, elegant tone of aspen wood integrates seamlessly with modern sauna interiors while helping to reduce the risk of accidental burns. With its compact footprint and minimal safety clearances, the CORE thrives in tight spaces and supports versatile installation options, including the ability to be fully embedded into a sauna bench.

Engineered for fast, efficient heating, the CORE Aspen allows direct contact between the stones and heating elements, producing rich, soft steam when water is ladled over the stones. Available in multiple power ratings, it accommodates a wide range of sauna room sizes and pairs effortlessly with HUUM UKU controls (sold separately) for precise, intuitive control.

Backed by a 3-year limited residential warranty, the HUUM CORE Aspen Sauna Heater embodies pure Nordic design—combining durability, versatility, and long-lasting relaxation in a beautifully refined form.
