Description

The Scandia Ultra Electric Sauna Heater (Large, 12 kW) is a commercial-grade, wall-mounted unit built from brushed stainless steel and sized for sauna rooms up to 980 cu ft. Designed and assembled in the USA, it offers flexible power options—208/240V, single- or three-phase—and straightforward external controls with a 60-minute timer and thermostat. The large rock tray supports authentic löyly while protecting the elements, and the compact chassis (26" L x 18" W x 29" H) tucks neatly behind or beneath upper benching in most layouts.

Engineered for reliability, the Ultra’s solid tray and built-in high-limit thermal cutout help safeguard the heater during frequent steam bursts, while the stainless shell resists corrosion in hot, dry environments. Scandia’s sizing guidance places the 12 kW model at up to 980 cu ft, ideal for generous residential rooms or light-commercial spaces with a standard 7-ft ceiling.

Electrical flexibility is a core advantage. Installers can select 240V single-phase (≈50 A) or 208V single-phase (≈57.7 A) service; three-phase configurations are also available (≈29 A @ 240V 3-ph; ≈33.4 A @ 208V 3-ph). This lets builders match the heater to on-site power without overspecifying service. The included control package mounts on an exterior wall for easy access, and sauna stones ship with the unit to streamline commissioning.

Performance remains consistent across heavy use: the large stone mass buffers temperature swings for a softer, more even heat profile, while the stainless shell and internal components are selected for long life under repeated thermal cycling. Clear installation documentation—covering wiring diagrams, control placement, clearances, and probe/sensor location—helps ensure safe, code-compliant results.

For buyers who want true rock-bed sauna feel with electric simplicity, Scandia’s Ultra 12 kW Large strikes a proven balance: durable materials, flexible power options, inclusive controls and stones, and room coverage up to 980 cu ft—all backed by Scandia’s long-standing warranty support.
