Q: What is the Climate Equalizer system?
A: Saunum’s patented system mixes hot ceiling air with cooler floor air, eliminating heat stratification and creating a uniform, head-to-toe sauna temperature with better breathing comfort.

Q: What makes it different from standard sauna heaters?

Q: Does it include smart or wellness features?
A: Yes. It integrates Himalayan salt spheres and optional aromatherapy capability, enhancing air quality and relaxation experience.

Q: Is a control system included?
A: No. It requires a separate Saunum control unit, which manages temperature, fan speed, and operation settings.

Q: What is it made of?
A: It features a black steel Scandinavian design with Incoloy stainless steel heating elements, built for durability and high-heat use.

Maintenance Tips

• Re-stack sauna stones regularly to maintain airflow and ensure the Climate Equalizer system distributes heat evenly.
• Replace cracked or deteriorated stones to preserve steam quality and protect heating elements.
• Vacuum or gently clean the stone compartment to remove dust, mineral deposits, and debris buildup.
• Keep air intake/exhaust paths for the climate equalizer system clear for proper air mixing performance.
• Do not overpack stones; proper spacing ensures correct airflow and prevents overheating.
• Wipe exterior black steel surfaces after cooling to prevent moisture stains and corrosion.
• Check heating elements during stone maintenance for scaling or damage (ensure power is fully off first).
• Inspect fan and internal airflow channels periodically and remove any loose debris carefully.
• Ensure sauna room ventilation remains unobstructed for stable temperature balance and efficiency.
• Schedule annual professional inspection of electrical connections, sensors, and control system for safe long-term operation
