PURPOSE:To improve the efficiency in operation of a radiation heating and reduce a loss of consumption power by a method wherein a number of rotation of a compressor and an indoor blower is controlled according to sensed temperature of a panel temperature sensor and a discharging temperature sensor of a compressor. CONSTITUTION:When a heating operation is started, a compressor 1 is driven and a panel temperature sensor 21 and a discharging temperature sensor 22 are operated. When the sensor 21 shows a temperature of 80 deg.C, an indoor blower 7 may operate with ULO and then a compressor 1 may rotate so as to keep 80 deg.C. If it exceeds 80 deg.C, the number of rotation of the compressor 1 is decreased down to a value where it shows 60 deg.C. Further, in a range of 60-80 deg.C, the number of rotation of the compressor 1 is increased or decreased. Further, if the sensed temperature of the sensor 22 reaches 100 deg.C, the number of rotation of the indoor blower 7 is increased in a range of LO. If it reached 120 deg.C, the number of rotation is decreased as shown at UL and the number of rotation of the compressor 1 is gradually decreased to wait until the detected temperature of the sensor 22 is lowered. In this way, if it lowers down to 80 deg.C, the number of rotation of the compressor 1 is decreased and the sensed temperature of the sensor 22 is kept at 80 deg.C.
