The Harvia The Wall SW-80 BLACK is an 8.0 kW wall-mounted electric sauna heater designed for medium-sized residential sauna rooms of up to 423 cubic feet. Designed and made in Finland, its matte black steel housing is 701 mm tall and only 259 mm deep, a slim profile that mounts where a bulkier heater will not fit.
Extra-long stainless steel heating elements maximize contact with the stone load for smooth heat transfer, while air circulated through the stone chamber and back into the room keeps temperatures steady across bench levels. An IPX4 splash rating covers the unit for full sauna and steam use. Its integrated controls sit on an illuminated, top-mounted panel for setting temperature and timer, and the panel installs on either side; flush bench integration allows a fully recessed installation. It runs on a standard 240V single-phase circuit, so no three-phase upgrade is needed. The included Harvia wall rack sets the correct floor safety distance automatically, and the heater is UL Listed for North America.
