Description
The Narvi Minex is a compact, wall-mounted electric sauna heater made in Finland for micro saunas and small cabins, with the 3 kW model suiting rooms of 2–3 m³ and the 3.6 kW model rooms of 2–4 m³. Despite its small footprint it carries up to 15 kg of stones, an unusually large capacity for a heater of this size, so water thrown on the stones produces a soft, pleasant löyly rather than harsh radiated heat. Temperature and timing are set with simple dials on the front of the unit, and Narvi’s 8.5 mm heating elements give a long service life with a low risk of overheating. The heater is supplied in a painted black finish and connects to a 230 V single-phase supply on a 16 A fuse; sauna stones are purchased 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.
Sauna stones
This heater requires up to 15 kg of sauna stones, purchased separately. We recommend 5–10 cm olivine diabase or vulcanite stones for the best performance.
