  • The Narvi NM is our entry level electric heater. It is an excellent choice when no ‘bell and whistles’ are required but the user still seeks Narvi’s renowned material and build quality, durability, and large stone capacity. This electric heater may be small but every consideration is made during design and manufacture to ensure the largest possible stone capacity as Narvi are true believers that great löyly is of paramount importance, a fact that sets them apart from all other sauna manufacturers. The heaters are only built with the finest quality materials in Finland, the home of sauna.

    The NM is manually control by dials that can be easily fitted on the left or right sides of the heater unit. The heating elements in the NM are Narvi’s own large diameter (8.5 mm) coils that reduce the overheating risk significantly and provide reliable performance throughout their long lifespan. The heater come in a number of finishes including matte grey, black, ground stainless steel (a brushed stainless steel finish) and bright stainless steel (a mirror finish). The NM is also available as a 4.5 kW model, ideal for exceptionally small saunas.

    This heater can be easily installed on both single phase and three phase power supplies by a qualified electrician. To learn more about installing electrical heaters on domestic power supplies, see our "How to choose the right electric sauna heater" page.
