The HUUM CORE is a premium electric sauna heater from Estonia — HUUM's signature design that blends industrial-quality stainless steel construction with Alder wood side panels for a heater that is as much a design object as it is a performance appliance. Where most electric heaters are functional hardware installed out of sight, the HUUM CORE is meant to be seen — its wood-panelled exterior complementing the sauna interior while simultaneously protecting users from contact burns on the hot steel surface.

Available in 6.5 kW, 9 kW, and 10.5 kW to cover rooms from 177 to 566 cubic feet, the CORE holds 66 lbs of stones in direct contact with industrial-quality heating elements — delivering consistent, intense heat and powerful steam. The compact 12.2" × 12.2" × 32.7" footprint with minimal safety clearances enables bench-embed installation. Compatible with HUUM's UKU control system. Backed by a 3-year residential warranty — the most comprehensive in the heater range.

Industrial steel. Alder wood. 66 lbs of stone in direct contact with the elements. The HUUM CORE — the heater that belongs in the room, not just in the corner. 🌿

🌲
Alder Wood Exterior — The HUUM CORE's Defining Design Feature
The HUUM CORE's Alder wood pre-fitted side panels do two things simultaneously: they create a seamless aesthetic match with the sauna interior — the heater looks like part of the room rather than an appliance installed in it — and they provide a tactile barrier that prevents accidental contact burns on the hot stainless steel surface beneath. Performance and safety expressed through design, not added as an afterthought. The Alder wood finish is what makes the CORE a centrepiece rather than simply a heat source.

Flexible Installation — Two Configurations

🪑
Bench Embed
The compact 12.2" profile and minimal safety clearances allow direct embedding into sauna bench seating — the cleanest, most integrated installation possible
🧱
Standard Floor/Wall
Flexible freestanding or wall-adjacent installation in corner or sidewall positions — minimal safety distances maximise usable bench space
🌲Alder wood pre-fitted side panels — aesthetic match and burn protection — the CORE's Alder wood panels are not decorative trim — they are a functional design decision that solves two problems simultaneously. The warm wood finish creates a seamless visual match with the sauna interior so the heater reads as part of the room rather than installed hardware. The panels also form a tactile barrier preventing accidental contact burns on the hot stainless steel surface — a practical safety consideration in any active sauna environment
🏗️Industrial-quality stainless steel construction — beneath the Alder exterior, the CORE is built from industrial-quality stainless steel throughout. Engineered for the demanding thermal and humidity cycling of regular sauna use — the construction standard that HUUM's Estonian manufacturing brings to every unit in the range
🪨66 lbs stone capacity — direct element contact — the CORE holds 66 lbs of stones in direct contact with the heating elements, not in a separate compartment above them. Direct thermal contact maximises energy transfer efficiency: stones heat faster, reach higher temperatures, and retain heat longer between pours than stones heated by convective air transfer alone. The result is consistent, intense heat and powerful steam that persists throughout the session
📦Compact frame — 12.2" × 12.2" × 32.7" — minimal safety distances — the CORE's compact 12.2" square footprint requires minimal safety clearances from bench, wall, and ceiling surfaces — a specification that significantly expands installation flexibility compared to larger heaters with greater clearance requirements. The minimal distances allow bench-embed installations and tight-corner positioning without compromising safety compliance
🪑Bench-embed capable — the most integrated installation option — the CORE's compact dimensions and minimal clearance requirements enable direct embedding into sauna bench seating — the cleanest, most architecturally integrated heater installation available. In a bench-embed configuration, the Alder wood exterior blends with the surrounding bench material, making the heater virtually disappear into the sauna interior design
🎛️UKU controls compatible — precise session management — the HUUM CORE pairs seamlessly with HUUM's UKU control system for effortless, precise heat management. The UKU provides intuitive temperature control from inside or outside the sauna. Contact us to discuss UKU control options alongside your CORE order
