FIELD: thermal engineering.

SUBSTANCE: invention is related to solid fuel heating devices, and can be used for heating various rooms with the possibility of long-term generation of fine steam in steam rooms of small saunas and baths. The sauna stove includes a body with a furnace space, an external chimney branch pipe, a fuel loading door, an internal heater installed at a distance from the body walls with the possibility of flue gases passing along the contour of the entire outer surface and having a chimney located coaxially with the external chimney pipe, a thermostatic control gate valve type containing a flat valve, a handle at one end and a valve, the side surface of which is associated with the handle, and on the opposite side is associated with a flat valve. The damper has a U-shape and, in position above the chimney, blocks the passage of flue gases into the external chimney from the front and sides of the inner heater and passes flue gases into the outer chimney from the chimney of the inner heater and from its rear side.

EFFECT: increase in the heating rate, increase in efficiency, an expansion of consumer features, a decrease in material consumption and an increase in ease of use, an increase in the service life.
