A stove fuelled with pellets for cooking food, comprising: - a frame forming internally a space, the frame comprising a dividing wall designed for subdividing the space into a chamber for cooking the food and a heating chamber; a burner for pellets positioned in the heating chamber for generating heat; a unit for feeding pellets to the burner operatively connected to the burner for feeding pellets to the burner; the unit for feeding the pellets being configurable between a plurality of conditions differing according to the quantity of pellets to be fed to the burner; - means of circulating hot air, positioned at least partially inside the heating chamber for forming a flow of hot air from the heating chamber to the cooking chamber so as to heat the food; characterised in that the stove comprises a control unit operatively connected to the unit for feeding pellets for adjusting the quantity of pellets to feed to the burner; the control unit being configured for controlling the unit for feeding pellets designed for adjusting the quantity of pellets to feed to the burner; means for measuring the temperature of the heating chamber operatively connected to the control unit for transmitting to the latter information relative to the measured temperature; wherein the control unit comprises a counter configured to count the heating time and in that the control unit is designed to perform the following operations: calculating the time for heating the cooking chamber to pass from a first predetermined temperature value to a second predetermined temperature value; comparing the measured heating time with at least one predetermined time value; modifying the condition of the unit for feeding pellets as a function of the comparison so that if the heating time is greater than the predetermined time value the feed unit is configured in a condition for feeding more pellets than the previous condition, if the heating time is less than the predetermined time value the feed unit is configured in a condition for feeding less pellets than the previous condition. - a frame forming internally a space, the frame comprising a dividing wall designed for subdividing the space into a chamber for cooking the food and a heating chamber; a burner for pellets positioned in the heating chamber for generating heat; a unit for feeding pellets to the burner operatively connected to the burner for feeding pellets to the burner; the unit for feeding the pellets being configurable between a plurality of conditions differing according to the quantity of pellets to be fed to the burner; - means of circulating hot air, positioned at least partially inside the heating chamber for forming a flow of hot air from the heating chamber to the cooking chamber so as to heat the food; calculating the time for heating the cooking chamber to pass from a first predetermined temperature value to a second predetermined temperature value; comparing the measured heating time with at least one predetermined time value; modifying the condition of the unit for feeding pellets as a function of the comparison so that if the heating time is greater than the predetermined time value the feed unit is configured in a condition for feeding more pellets than the previous condition, if the heating time is less than the predetermined time value the feed unit is configured in a condition for feeding less pellets than the previous condition.
