What our Experts Think

• Powerful upgrade for larger saunas
  The 9kW output is ideal for medium–large sauna rooms (≈283–460 cu. ft.), delivering stronger, faster heating compared to smaller models—perfect for multi-user or outdoor setups.
• High stone capacity = premium steam quality
  Holds up to ~55 kg (121 lbs) of stones, producing softer, longer-lasting heat and richer steam (löyly) than typical electric heaters.
• Fast, efficient heat-up performance
  Engineered for quick heating to sauna temperatures (~60–100°C) while maintaining energy efficiency—important for frequent use.
• Iconic, design-forward heater
  The signature water-drop shape (Red Dot award-winning) transforms the heater into a centerpiece, not just a utility.
• Wall-mounted, space-saving build
  Compact footprint frees up floor space while still delivering high-output performance, making it flexible for custom sauna layouts.
• Premium materials & engineering
  Built with stainless steel and industrial-grade heating elements, designed for durability and consistent performance.
• Smart control ready (modern convenience)
  Compatible with UKU digital & Wi-Fi controllers, enabling remote preheating and precise temperature control.

Maintenance Tips

• Re-stack & replace sauna stones regularly (6–12 months): Maintain airflow and heat efficiency; cracked stones reduce performance. Large stone capacity (~122 lbs) requires proper spacing.
• Use clean, fresh water only: Avoid oils, salt, or chemicals to protect heating elements and prevent residue buildup.
• Keep stones loosely packed: Proper airflow between stones ensures consistent, soft heat and prevents overheating.
• Inspect heating elements periodically: Ensure no direct stone pressure or damage—this extends heater lifespan and avoids costly repairs.
• Wipe exterior & remove moisture: Prevent corrosion on stainless steel surfaces and maintain a clean look.
• Check ventilation & sauna airflow: Adequate air circulation improves heating efficiency and prevents safety shutdowns.
• Descale in hard water areas: Mineral buildup can affect performance over time—clean periodically if needed.
