You can select the stainless steel finish on the page, where a black finish is also available.
The box holds the heater and its manual, and it runs on a 240 volt circuit. The stone guard and illuminated dial for on, off, time, and temperature are built in. You can preset it to start up to 8 hours ahead, and the controls are on the heater, so there is nothing else to wire in. Sauna stones are sold separately, so add the 1 box it needs on the page. A bucket and ladle set is optional. Smaller room? The Harvia The Wall SWS60 sauna heater is the 6 kW version. The Harvia The Wall SWS80 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Does this heater have built-in controls?
Yes – illuminated control switches on the SWS80 handle on/off, time, and temperature, with a preset timer of up to 8 hours, so no separate control unit is needed. Built-in overheat protection and a built-in stone protector are also part of the heater’s stainless steel housing.
What room size is it designed for?
It is an 8kW heater for medium-sized saunas: the specification table lists a range of 176 to 423 cubic feet. The wall-mounted design was also shaped for superior air circulation, which the description credits with keeping the sauna room’s temperature more consistent throughout.
Can I choose which side it is installed on?
Yes – the heater may be installed in either a left- or right-handed direction to accommodate your room layout, and it can even be integrated into the sauna bench. A specialized wall-mounting rack is included, and it facilitates the minimum safety distance between the heater and the floor.
Does it need sauna stones?
Yes – the Features tab specifies a minimum of 44 lbs of sauna stones, and stones are not listed in the box contents, so plan on ordering Harvia sauna stones along with the heater. Harvia also recommends an additional box so you can choose the highest quality stones for fit, form, and function.
What electrical service does it require?
The specification table lists 240V single-phase power. Installation must be performed by a licensed electrician in accordance with the installation and operation manual linked on this page and your local electrical codes, which govern the wiring and breaker sizing for a heater of this rating.
What is included, and where is it made?
The box includes the sauna heater and its installation and operation manual, backed by a 2-year full consumer warranty plus a 5-year service warranty. Like Harvia’s other wall-mounted and floor-standing electric sauna heaters, it is designed, engineered, and made in Finland.
