Description
The Narvi Smooth (Wi-Fi Controlled) is a Finnish-made tower heater that pairs Narvi’s renowned build quality with an understated Nordic column design, supplied complete with the Narvi Flow Wi-Fi controller. Its freestanding black column holds 100 kg of stones, heated by three full-length 8.5 mm elements that bring the sauna up to temperature quickly and create an excellent soft löyly when water is thrown. The upper part of the casing lifts off, so the lower stones can be placed easily during installation and changed without dismantling the heater, while 100 mm side and front clearances allow compact and corner installations. From the Flow controller you can start the heater, set the temperature and schedule heating times, with remote operation through the free Narvi Flow app. The Smooth is offered in 6.8 kW and 9 kW outputs for single-phase or three-phase supplies and a 10.5 kW output for three-phase supplies, covering sauna rooms of 5–18 m³; sauna stones and the optional installation flange are sold separately.

Installation
Installation and maintenance must be carried out by a certified electrician, with the electricity supply isolated at the fuse panel before any work begins. Under IEC 60364-7-703 and BS 7671:2018 an electric sauna heater does not have to be connected through an RCD, and for reliable operation the manufacturer recommends that the heater supply is not run through one; other electrical devices in the sauna room should be RCD protected. A local point of isolation covering all live conductors is recommended. The installation manual in the Downloads tab and local wiring regulations must be followed. The Smooth is floor-standing, and its shape permits a corner installation to save space. The optional installation flange allows the heater to be fixed within the sauna benching.
Sauna stones
The Smooth takes up to 100 kg of 5–10 cm stones, and we recommend Olivine Diabase or Vulcanite sauna stones, sold separately. The stones must cover the heating elements completely and should be replaced every six months.
Brand
Narvi is a Finnish maker of sauna heaters, and every Narvi heater is CE tested and carries the Finnish Key Flag, awarded to products designed and made in Finland.
Warranty
The warranty on this heater is 2 years in private use, with a 12-month warranty on the heating elements.
