Narvi Peak Big Commercial Electric Sauna Heater

About this Narvi Electric Sauna Heater 

*Stones, thermo pine heater guard & controller to be purchased separately* 

This heater requires up to 180kg of sauna stones. We recommend using a mix of the 5-10cm (60kg) and 10-15cm (120kg) Olivine Diabase or Vulcanite Sauna Stones for optimal performance.

The Narvi Peak Big offers a top-class spa experience for large commercial settings. Narvi Peak Big commercial electric sauna heater is Finnish- made with a captivating appearance and large capacity for stones. Thanks to its oval shape and feet, the heater can be easily placed into the sauna to complement different designs.  

The heater is designed to last in demanding conditions, making it an excellent choice for health clubs, spas and gyms.  

A thermo-pine heater guard has been specifically designed for the Narvi Peak Big, which can be purchased separately here.

The heating and timing are controlled by a separate control panel. Additionally, there is a separate power and thermostat unit, which make sure that the desired temperature is achieved and maintained over a continuous time period.  

Required control and power units: 

• Control unit C-2003, suitable for heaters between 18kW-33kW
