Aitokiuas AK47 - AK57K

Aito-sauna heater is the traditional heat storing sauna heater, which lets you enjoy the steam in its most true form. After one heating, this legendary stove guarantees a great sauna until morning. The large amount of rocks allows just the right kind of oxygenous heat, which is easy to regulate. The unique enamelled steel casing makes the stove long-lasting and easy to clean.

The sauna heater is delivered with extremely durable sauna heater stones, which decrease the time of heating. The round shape of the ceramic stones improves draft. The heat endurance of the stones is first class and this will extend the usage age of the stones.

The casing of the sauna heater has been insulated and the insulation has been protected with rustproof steel sheet. The firebox is made of fireproof mass and cast elements. The stone compartment has been lined with fire bricks. The opening of the hatch, the fire grate and inner lid of the sauna heaters are made of cast iron. 

The sauna heater will be shipped in parts that are ready to be installed. The parts will be assembled without plaster onto the desired spot. The shipment will include all necessary parts.
