Ermak 20 Premium wood-burning sauna stove is a modular sauna stove with a firebox and smoke ducts made of durable steel.
Designed for saunas with a size of 12-22 m3. The spacious open rock storage has the option of installing a closed rock storage module and installing a steam cannon. Made of high quality durable steel. The furnace hearth, smoke ducts and stone container are made of structural steel. At locations of maximum heat loads, the steel thickness is 11 mm, the furnace vault is 8 mm, and the walls of the firebox and flues are 3-4 mm. The thickness of 6 mm steel in the furnace increases the service life of the furnace and makes the heating of the furnace elements more even. The large volume of stones (60 kg) maintains a comfortable and soft temperature in the steam bath for a long time. Large heat transfer area. The stones are heated strongly and evenly from all the walls of the stove, removing the temperature as much as possible and protecting them from direct radiation. The door can be mounted to open to the right or left. The design of the furnace provides the possibility to install a heat exchanger in the furnace on either side to heat the water in the remote tank. Compactness, structural strength and a well-developed heat transfer system - the uniqueness of Ermak sauna heaters.
Designed to produce light and finely dispersed steam. The design of the device allows water to enter the very center of the stone reservoir, where the stones are the hottest. The water that gets on the hottest stones evaporates in a flash, creating a quality and light steam.
For water heating, you can use a heat exchanger built into the furnace firebox, which you connect to a separate water tank, where the water is heated by natural circulation. The heat exchanger is convenient to use when the water tank is in a place other than the stove, e.g. in the washbasin or shower. The heat exchanger can be mounted on both the right and left side of the stove.
For greater heat storage, a suspended mesh can be used for stones that can hold up to 50kg of stones, and this mesh reduces unwanted sharp and burning infrared radiation. The net can be hung on both the right and left side of the oven, or on both sides.
