Summary:PROBLEM TO BE SOLVED: To provide an antifreezing system further reduced in power consumption. SOLUTION: This antifreezing system 30 comprises a control device 31 for preventing pipes from being frozen by supplying power to self-temperature control heaters 35-38 installed along a water supply and/or hot-water supply pipe. The control device 31 comprises a first function for starting the supply of power to the heaters under a first temperature condition detected by a temperature sensor 32 and stopping the supply of power to the heaters 35-38 under a second temperature condition, a second function for supplying power to the heaters 35-38 for only a first time irrespective of the temperature detected by the temperature sensor 32, and a selective function capable of switching the first function and the second function.
