Electric sauna heater - NARVI ULTRA BIG

NARVI ULTRA BIG is an electric sauna heater designed for large and intensively used saunas. It is available in 18 kW, 24 kW and 30 kW power versions, allowing the heater to be selected according to the size of the sauna room.

The NARVI ULTRA BIG is designed for intensive use. The heater components are made from corrosion- and wear-resistant materials, while the durable heating elements are intended for long-term operation. Thanks to these features, the heater is particularly suitable for hotels, SPA centres, sports clubs, shared saunas in apartment buildings and other intensively used sauna facilities.

All power versions hold up to 120 kg of sauna stones. The large stone capacity allows the heater to store a significant amount of heat and provide even steam in a large sauna room. The recommended sauna stone size is 5–10 cm.
