Between Living · Sauna Heaters · The Heart of the Sauna

Heat begins here. The ritual follows.

The sauna room creates the setting. The heater creates the experience. Its output, stone volume, airflow and response shape how warmth moves through the room, how water becomes löyly, and how the body ultimately encounters the heat.

Choose the heater first. Let the sauna form around the heat you want to feel.

Begin with the maker. Each approaches heat differently through stone volume, airflow, material, control and the architecture of the sauna itself.

Where the Heater Becomes Löyly

Heat Needs Stones.

A sauna heater creates the heat, but the stones determine how that heat is held, softened and released. They receive the water, transform it into löyly, and help shape the warmth that moves through the room. Complete your heater with stones chosen for the sauna experience you intend to create.

Intelligent control, wherever you are

Prepare It From Anywhere.
Fenix Learns the Rest.

Harvia Fenix makes everyday sauna use remarkably simple. Through the MyHarvia app, you can begin preparing your sauna while you are away from home, check its status, and return to a room that is ready when you are. Its built-in intelligence learns how your particular heater and sauna room warm over time, then adapts its preparation for a more consistent experience. Instead of repeatedly managing every detail, you choose how you want the sauna to feel and Fenix helps take care of the journey there.
