Abstract: The invention concerns a stove comprising a burner, a combustion chamber, transport and exit ducts for the combustion gases, and at least one heating unit, such as a hearth plate or an oven. According to the invention, the stove comprises warm air duct with inlet and outlet and a blower, arranged to circulate air into said warm air duct to be heated by the heating unit and out from said duct. The stove may consist for instance of a lid lowerable over the hearth plate so that the warm air duct becomes confined between the lid and the hearth plate. When the stove comprises an oven, the warm air duct may conduct the air to be heated on the other hand into the oven and on the other hand into the intermediate space confined between the outer surface of the transport duct for the combustion gases.
