Harvia The Wall SW80 8kW Electric Sauna Heater — Black

Wall-Mounted Electric Sauna Heater for Rooms 177–431 cu ft | ETL Listed | Built-In Controls | Made in Finland

The Harvia The Wall SW80 is an 8kW wall-mounted electric sauna heater designed for sauna rooms from 177 to 431 cubic feet. Its sleek black steel exterior, illuminated built-in top-mounted controls, and compact Scandinavian profile make it an excellent choice for modern sauna installations where appearance and space efficiency both matter.

Engineered for improved air circulation and steady warmth, the SW80 delivers a consistent, comfortable sauna environment. The control panel can be installed on either the left or right side of the heater to suit your layout, and the heater can optionally be integrated into the sauna bench for a seamless built-in look.

Important: Sauna stones and a dedicated 240V electrical connection are required and sold/arranged separately.

Who This Is For

The SW80 is ideal for homeowners and sauna builders who want a premium wall-mounted electric heater with built-in controls and a clean black aesthetic for a small to mid-sized sauna room. It steps up from the 6kW SWS60 when your room size or material load requires more output, while keeping the same compact Wall Series footprint.
