Product description

Product Description

AK stands for Aito Kiuas, which is Finnish for ‘Genuine Stove’. The sauna heater bears this name, because these traditional heat storing sauna stoves are based on the original sauna heaters used throughout the last century in Finland. Naturally the design has come a long way, being perfected by decades of Finnish ingenuity. Unlike the other constantly burning heaters, these legendary heat storing stoves require only a single heating to provide excellent sauna until the following morning. The huge stone capacity delivers exactly the right kind of high oxygen heat for the truest löyly which is easily regulated, even by a sauna novice.

The enamelled steel finish is the perfect choice for a durable heater, ensuring rust resistance and making is a pleasure to clean. This heater comes with extremely durable, fast-heating stones that extend their usage life and decrease the required heating time. The AK stoves are the top class heaters for the true sauna connoisseur. A fact that has lead the Finnish president, Sauli Niinistö, to choose this heater for his personal sauna. Needless to say, their constant heat supply is an excellent bonus when fitting sauna around his busy schedule.

The heat storing heater works by combining the high specific heat capacity of the large volume of olivine or ceramic stones with an insulated casing. In line with our Endurance ethos, the heater is protected with enamelled rustproof steel, the stone compartment is lined with fireproof bricks and the firebox made from cast elements and fireproof mass. Furthermore, the inner lid, fire-grate and hatch are made from high quality cast iron. The AK-47 and 57 heaters are also available as tunnel model heaters, which is truly the ideal option for the user who insists on a tranquil sauna experience. The AK-57 is also available with a white enamel coating.

The heaters require durable ceramic stones sauna stones due the high heats within the heaters. Both the AK57 and AK57 are available with heater tunnels that allow the heater to be fueled from the outside of the sauna room through the wall. These can be purchased separately here. The AK57 is also available with a extension piece that makes the heater taller (AK57K modification), which is particularly useful where the sauna or banya has raised or mezzanine benching. The AK57K also considerably increases the heaters stone capacity for a further improved löyly. The AK57K extension piece can be purchased here along with the additional ceramic stones required.
