Product description

Wall Mountable Narvi Minex Electric Sauna Heater.

The Narvi Minex domestic electric sauna heater is specially designed to fit in small or micro saunas and sauna cabins. It is ideally suited to fit in small spaces within saunas that have a smaller internal capacity. Whilst the heater itself is small, as with all Narvi heaters, it boasts the largest stone capacity for it's size on the market. At 3kW and 3.6kW variants, this sauna heater is also perfect for homes with not much available power capacity - ideal for fitting a shower-sized micro sauna in apartments, small homes or "tiny-houses".

This electric sauna heater may be Narvi's smallest but every consideration is made during design and manufacture to ensure the largest possible stone capacity. A large stone capacity is what creates a pleasant relaxing heat (not a harsh radiated heat characteristic of heaters without stones) and onto these sauna stones, water can be thrown creating the löyly (or sauna steam). Their drive to produce highly durable, authentic Finnish sauna heaters with large stone capacities is what sets Narvi apart from all other sauna heater manufacturers. The sauna heaters are only built with the highest grade materials, in Finland, the home of sauna.

The Narvi Minex is manually controlled by dials on the front of the sauna heater unit. The heating elements in the Minex are Narvi’s own large diameter (8.5 mm) coils that reduce the overheating risk significantly and provide reliable performance throughout their notoriously long lifespan. The heater comes in two finishes: black & stainless steel. 

This heater must be installed by a qualified electrician.
