Its innovative design clearly sets itself apart from its closed-structured NM model. This electric sauna 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 \u003cem\u003elöyly\u003c\/em\u003e is of paramount importance. A fact that sets them apart from all other sauna manufacturers. The heaters are only built with the highest grade materials, in Finland, the home of sauna.\u003c\/p\u003e\n\u003cp\u003eThe Narvi NS is manually controlled by dials that can be easily fitted on the left or right sides of the sauna heater unit. The heating elements in the NS 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. This sauna heater comes in two finishes, including black and bright stainless steel (a mirrored stainless steel finish). The NS is also available as a 4.5 kW model, ideal for exceptionally small saunas.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis heater should be fitted by a qualified electrician.
