Abstract

PURPOSE: To prevent freezing by utilizing the natural convection generated by the heating of a heating portion provided at a proper place in the mixing type water course construction having a bypass passage for a heat-exchanger.
CONSTITUTION: The high-pressure chamber 14 of the water governor 1 and the hot water pipe 6 of the boiler consisting of water supply pipe 5, said water governor 1, a pipe 3, a heat-exchanger 2, a pipe 4, and said hot water pipe 6 are intercommunicated by a bypass hole 20, and a bypass valve 21 is supported by a diaphram 13 for securing a small flow of water when water supply is stopped. A heating portion 24 having a heater 25 is formed in the vicinity of a bypass hole 20, and said heater 25 is set to ON/OFF by a thermostat 28.
