Description
The Narvi Velvet (Wi-Fi Controlled) is Narvi’s premium floor-standing electric heater, handcrafted in Lapinkylä, Finland, with a slender black column that holds a remarkable 140 kg of stones for long-lasting, deeply soft steam. The two-part outer casing makes loading the stones far easier, and an optional black installation flange lets the heater be recessed into the benching for a clean, built-in finish. The supplied Narvi Flow Wi-Fi controller starts the heater, sets the temperature and schedules heating, with remote operation through the free Narvi Flow app; a door switch and separate temperature sensor are included, and two restricted modes (On/Off and Easy) suit community saunas, rentals, hotels and families with children. The Velvet is available as a 9 kW model for single-phase or three-phase supplies and a 10.5 kW model for three-phase supplies, covering sauna rooms of 8–18 m³. Sauna stones are sold separately, as are the installation flange, heater guard, controller extension cables and humidity sensor.

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 Velvet is floor-standing and can be recessed into the benching with the optional installation flange, or installed in a wall recess, observing the clearances above. The control unit must not be installed in a wall recess.
Sauna stones
The Velvet takes up to 140 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.
