To provide a floor heating system capable of informing replenishment time of circulating liquid by using only existing components without additionally providing a float switch and a detection sensor.
The floor heating system includes: a circulating circuit for circulating the circulating liquid in a floor temperature control panel; a heat pump system for controlling the temperature of the circulating liquid within the circulating circuit; a temperature sensing part 47 for sensing the temperature of the circulating liquid within the circulating circuit; a data storage part M for storing data indicating a relationship between the reduction amount of the circulating liquid within the circulating circuit per unit time and the temperature of the circulating liquid within the circulating circuit; a circulating liquid amount detecting part 51 for detecting that the amount of the circulating liquid within the circulating circuit is decreased to predetermined amount based on the temperature sensed by the temperature sensing part 47 and the data stored in the data storage part M; and an alarm informing part 52 for issuing an alarm to urge replenishment of the circulating liquid, when the circulating liquid amount detecting part 51 detects that the circulating liquid within the circulating circuit is decreased to the predetermined amount.
