Abstract
A gas furnace for heating an indoor space including a burner forming high-temperature exhaust gas by combusting fuel; an exhaust path in which the exhaust gas flows; a blower for suctioning internal air via a suction path; a supply path for guiding the internal air exhausted by the blower toward the indoor space, after heat-exchanged with the exhaust path; a valve of which an opening degree is controllable so as to supply a predetermined heat-power-based amount of fuel to the burner; and a controller controlling the opening degree of the valve based on a signal transmitted from a thermostat installed in the indoor space, wherein the heat power of the burner is controlled in different heat power levels based on the opening degree of the valve, and a controlling method of the gas furnace for heating the indoor space.
