Harvia AC3000 Split-Face Sauna Stones
The Harvia AC3000 5-10 cm sauna stones are suitable for all-electric and wood-burning Harvia sauna heaters.
Only available with the purchase of a Harvia sauna heater or stove.
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.
