Accessories and Add-ons

The following options should be considered with your heater purchase.

Sauna Stones 

Required for Operation. Sold Separately.

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 Harvia AC3020 stones are 4-6 in (10-15cm) in size and designed for use with Harvia sauna heaters and stoves. Each natural stone is unique in shape and size so we recommend purchasing an additional box of sauna stones to allow you to choose the highest quality of stone for fit, form, and function.

The AC3020 stones work for the following Harvia Sauna Heaters:

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

HARVIA 20 PRO Sauna Stove requires approximately: 88lbs sauna stones with a diameter of 4-6 in (10-15 cm). 2 boxes x 44lbs

HARVIA Declaration of Performance

For Simple Sauna Sizing, please follow the link HARVIA - Sizing Your Heater. Choose the heater with power adequate to the cubage of the sauna room.  However, for non-insulated walls (brick, glass block, glass, concrete, etc.) a more powerful heater is needed. Add 1,2 m³ to the cubage of the steam room per each square meter of uninsulated wall. For example, a 10 m³ sauna room with a glass door corresponds to the power requirement of a 11.5 m³ sauna room.
