What Your Body Will Feel After One Week

Experience the difference of professional-grade recovery technology

No Gas Line Needed

Electric installation is simpler than gas — no gas supply line, no combustion, no licensed gas technician. All you need is a dedicated 240V circuit from your licensed electrician.

Precise Temperature Control

Electric heaters deliver consistent, accurate temperature control session after session. Set your preferred heat level and the Ultra maintains it reliably — no combustion variability.

Authentic Löyly Steam

Pour water over fully heated rocks for bursts of authentic Finnish löyly steam. It's the hallmark of a real sauna experience — and the Scandia Ultra's rock cradle is engineered for exactly this.

Frequently Asked Questions

Everything you need to know about the Scandia Electric Ultra Sauna Heater - Large

The Large model (12–18 kW) is designed for saunas up to approximately 600+ cubic feet. A general sizing guideline is 1 kW per 45 cubic feet of sauna space. For rooms with glass walls, exterior-facing surfaces, or ceilings above 7 feet, size toward the higher kW end to ensure adequate heat output.

The Large model requires a dedicated 240V electrical circuit with appropriate breaker size and wire gauge for your selected kW rating. Installation must be performed by a licensed electrician per local building codes. Refer to the installation manual for specific amperage, breaker sizing, and clearance requirements.

Absolutely. The Scandia Electric Ultra includes a rock cradle designed for authentic löyly steam. Once rocks have reached full temperature (typically 25–35 minutes after start), ladle water over them for bursts of invigorating Finnish steam. It's one of the key advantages of this heater over models that don't support rocks.

Both deliver authentic sauna heat and löyly steam. The Electric Ultra is easier to install — just a 240V circuit, no gas line or combustion venting required. It also offers more precise temperature control. Gas heaters typically heat up faster and cost less to operate where gas rates are low. The right choice depends on your property's fuel access and installation setup.

The Large (12–18 kW) is designed for saunas from roughly 350 to 600+ cubic feet. Smaller Scandia Electric Ultra models cover saunas under 350 cubic feet. Choose the Large if your sauna room is spacious, has high ceilings, or includes heat-demanding features like glass walls or exterior-facing construction.
