Experience comfort and efficiency with the Harvia Pro 20 LS 24.1kW Wood-Burning Sauna Stove with Water Tank — a dual-function heater designed to deliver authentic Finnish warmth to your sauna while creating a cozy fireplace atmosphere in the adjoining room.

Harvia Pro 20 LS is a popular choice for cottage settings because of its practicality. On the left side of the heater is a fixed and easy-to-use 30-litre water tank, which heats the water at the same time as the heater heats up.

The Harvia Pro model has a graphite black exterior and a stainless-steel front. The heater's impressive glass hatch creates an atmosphere in the sauna and the large stone space ensures excellent sauna experience for rooms from 283 to 706 cubic feet.
