Harvia Stone Requirements

HARVIA 3020

Genuine Harvia sauna stones are selected according to old traditions and convey a genuine sauna atmosphere. Harvia sauna stones provide good and soft heat. Split-face sauna stones are the only correct stones for electric heaters and woodburning stoves because they can store lots of heat and the water evaporates efficiently from the wide surface of the fracture. Angular split-face stones also allow for loose placement of the stones, which is the most important requirement, particularly in electric heaters in order to make it possible for the heat to be conveyed to the sauna room between the hot stones and heating elements. Good air circulation in the stone space makes the electric heating elements last for as long as possible.

The AC3020 stones work for the following Harvia Sauna Heaters-

Virta Series
AF (Forte) Series
M Series
Pro Series
Legend Series

CAUTION: Light (ceramic), soft (soapstone), and smooth (rounded) sauna stones do not produce the desired results and they may cause problems in electric heaters in particular.
