Heaters

The heater is the heart of the sauna.

SAWO builds more than one hundred models across six series. We help you choose one — for the room, the ritual, and the climate it lives in.

The six series

Six ways to hold the heat.

Across the series, outputs run from 2.3 to 24 kW; commercial models reach 36 kW.

  • STONE PILLAR — TOWER SERIES

    Tower

    Stone-pillar heaters — stainless rings carrying a deep mass of stone, circulating heat and steam evenly around the room.

  • Floor

    Freestanding, movable, high-performance — heat placed wherever the room wants it.

  • Wall-Mounted

    Compact heaters that free the floor. Many wear a cool-to-touch fiber coating to help prevent accidental burns.

  • Stone

    Heaters bodied in Finnish soapstone, a stone prized for how it stores and conducts heat.

  • Combi

    Heater, steamer, and aroma basin in one unit — dry heat and soft steam from the same corner of the room.

  • STEFAN LINDFORS — DRAGONFIRE

    Dragonfire

    The designer series, crafted by Finnish designer Stefan Lindfors — his Junglefire pattern drawn into the fiber coating.

The heater's own science

How löyly works.

Heater, stones, water, löyly — the soft rise of steam when water meets hot stone — and the temperature and humidity zones it creates in the room.

For hotels & resorts

Commercial heat, to 36 kW.

SAWO's Taurus series runs from 9 to 36 kW for commercial duty — spa circuits, wellness floors, and clubs that hold heat all day. Our hospitality track covers planning, equipment, and service.
