Buying Guide: Key Purchase Considerations

  • Space and heater type: True sauna heaters (9KW, 6KW) are best for dedicated sauna rooms, while plug-in space heaters can supplement warmth in adjacent spaces. Match heater capacity to room volume (cu ft) and insulation quality.
  • Electrical requirements: High-wikth sauna heaters require dedicated circuits and proper circuit protection. Check home electrical capacity and local codes before installation. Smaller plug-in heaters are generally 120V outlets but may still trip circuits if used with heavy loads.
  • Safety features: Look for overheat protection, flame-retardant materials, ETL/CSA certifications, and cool-touch housings for spaces used by children or pets. External controllers can reduce the need to enter hot spaces during cycles.
  • Control and scheduling: Timers and programmable thermostats help optimize energy use and comfort. External digital controllers with easy-to-read displays improve usability in spas and dressing areas.
  • Heat distribution and stone requirements: Traditional sauna heaters rely on sauna stones for radiant heat and humidity. Stones are typically not included, so factor in additional components and safety clearance for installation.
  • Noise and vibration: For a relaxing spa environment, select models designed for quiet operation, especially if the heater is near living spaces or bedrooms.
  • Portability and installation: Portable plug-in heaters provide flexibility for interim setups but may be less efficient for larger sauna rooms. Built-in sauna heaters require professional installation and proper ventilation.
  • Energy efficiency: ECO modes and variable wattage help reduce energy costs. Compare outputs in relation to the room size and desired heat level for optimal efficiency.
