Electric Sauna Heaters — Frequently Asked Questions

How do I size an electric sauna heater?
A common rule of thumb is about 1 kW per ~45–50 ft³ (1.3–1.4 m³) of room volume. Add capacity for large glass areas, uninsulated walls, or very high ceilings. Always confirm with the manufacturer chart.
What power do I need—120V or 240V?
Most full-size heaters use a dedicated 240V circuit (amperage varies by kW). Small, boutique units may use 120V. Follow the product manual and use a licensed electrician.
Built-in vs. external controls?
Built-in controls live on the heater; external controllers mount outside the hot room and often add Wi-Fi/app, presets, child lock, and remote start (where permitted).
Why does rock capacity matter?
More stones = more thermal mass for stable heat and better steam pours. If you love löyly, prioritize a heater with a larger stone basket.
Wall-mount or floor-mount?
Wall-mount saves space and suits small/medium rooms. Floor-mount units handle higher outputs, larger baskets, and heavy use.
Can I use an electric heater outdoors?
Use outdoor-rated rooms and follow all electrical and weatherproofing requirements. Heaters themselves are typically installed inside the enclosure.
Do I need ventilation in an electric sauna?
Yes. Proper intake and exhaust improve comfort, air quality, and heater performance. Follow the room manufacturer’s vent layout.
Are essential oils safe on stones?
Never pour oils directly on stones. Add a few drops to a ladle of water (if permitted by the heater manual) or use accessories designed for aromas.
How long to heat up?
Typically 30–45 minutes depending on room size, insulation, stone mass, and starting temperature.
Any code or safety notes?
Use a licensed electrician, correct wire gauge/breaker, proper clearances, and follow local codes and the product manual. Mount guards where required.

Buying Guide: Choosing an Electric Sauna Heater

Step 1 — Size by Room Volume

  • Volume: (Width × Depth × Height). Rule of thumb: ~1 kW per 45–50 ft³.
  • Adjustments: Add capacity for glass doors/walls, stone/brick, or poor insulation.

Step 2 — Pick Mount & Controls

  • Mounting: Wall-mount (compact) vs floor-mount (heavier baskets/higher kW).
  • Controls: Built-in simplicity or external controller with Wi-Fi/app & presets.

Step 3 — Steam Feel (Rock Basket)

  • Stone Mass: Larger baskets store heat for richer, longer steam pours (löyly).
  • Pouring: Use clean water only; follow the manual.

Tip: If you love frequent steam pours, choose a heater with higher stone capacity and plan ventilation accordingly.
