Description
The Narvi Ultra Small is a Finnish-made commercial electric sauna heater scaled for small commercial saunas in gyms, spas and hotels, and for domestic saunas in daily use. Like the rest of the Ultra series it is stainless steel inside and out, with some of the highest material thicknesses on the market, and elements of a thickness and grade that welcome generous water over the 30 kg stone mass. It is sold here as the 6 kW model in a painted black finish, suited to sauna rooms of 5–8 m³ and connectable to a single-phase or three-phase supply. Heating and timing are managed from a separate control unit (Narvi Basic N2014E, or the T-2003 daily or B-2003 weekly panel), and the control unit and sauna stones are sold separately. A Wi-Fi controlled version of the Ultra Small, with further output and finish options, is listed 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 Ultra Small is floor-standing and can also be fastened to the wall as shown in the installation manual.
Sauna stones
The Ultra Small takes up to 30 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.
