PROBLEM TO BE SOLVED: To prevent abnormal high temperature of a floor heating panel upon starting an operation in a composite warm water heating system and hence improve comfortability. SOLUTION: Upon starting a composite heating operation with an indoor machine 2 and a floor heating panel 3 the operation is usually started at an 8 speed of a maximum heating capability, and warm water heated to high temperature (75 deg.C) in response to the 8 speed in a heating heat exchanger 12 is supplied to the indoor machine 2 and the floor heating panel 3 to quickly raise indoor temperature. When fresh air temperature detected by a fresh air temperature thermistor 404 upon starting of the operation exceeds 15 deg.C, and set temperature of a remote controller 4 exceeds 27 deg.C, the operation is started at a 6 speed, a smaller heating capability than the 8 speed, and there is supplied warm weater heated to a high temperature (67 deg.C)) in response to the 6 speed slightly lower than the 8 speed. Temperature of the warm water supplied to the floor heating panel 3 is lowered owing to heat dissipation so that it can be suppressed to a predetermined surface temperature (36 deg.C) without reaching abnormal high temperature.
