PURPOSE:To obtain an effective space-heating apparatus which is capable of heating a space to be air-conditioned promptly, by using a floor heating apparatus and a high-temperature radiation heating apparatus in combination. CONSTITUTION:In case that the temperature of air detected by a room-temperature detector 3 is higher than a prescribed value at the initial stage of space- heating operation or when the room temperature is lowered during space-heating operation by disturbance such as abrupt drop of the atmospheric temperature or increasing of the ventilating rate, an ON control signal is given from a voltage comparator 6 constituting a control unit 4 to a power circuit 7 for an electric stove and a high-temperature radiation heating apparatus 2 consisting of an electric stove is set into operation. Through operation of the high-temperature radiation heating apparatus 2, the temperature of air in a room to be air-conditioned is raised. When the temperature of air in the room becomes higher than a prescribed value, an OFF control signal is given from the voltage comparator 6 to the power circuit 7 to stop operation of the high-temperature radiation heating apparatus 2. |
