SYSTEM FOR SUPRESSING OF DAMAGE BY COLD WETHER FOR HOT WATER BOILER

摘要

The present invention relates to a system for preventing a hot water boiler from freezing and bursting. Specifically, the system for preventing a hot water boiler from freezing and bursting includes: a boiler device; a direct water pipe connected to the boiler device and supplying tap water into the boiler device; a heating supply pipe connected to the boiler device and supplying heating water heated in the boiler device to an area to be heated; a heating water return pipe connected to the boiler device and returning the heating water in the boiler device as the heating water is supplied and circulates through the heating supply pipe; a hot-water supply pipe connecting the boiler device and a hot water distributor and supplying the hot water heated in the boiler device; a first freezing prevention pipe bypassed on the heating supply pipe and adjacent to the hot-water supply pipe; a second freezing prevention pipe bypassed on the heating water return pipe and adjacent to the direct water pipe; and a freezing prevention unit individually installed between the hot-water supply pipe and the first freezing prevention pipe and between the direct water pipe and the second freezing prevention pipe. The system for preventing a hot water boiler from freezing and bursting enables the distance between the hot-water supply pipe and the first freezing prevention pipe and the distance between the direct water pipe and the second freezing prevention pipe to be formed to be fixed by the freezing prevention unit. Therefore, the system for preventing a hot water boiler from freezing and bursting can easily arrange the distance between a branch pipe and the hot-water supply pipe and between the branch pipe and a water supply pipe at fixed intervals. Therefore, the system for preventing a hot water boiler from freezing and bursting can minimize thermal loss and prevent the direct water pipe and hot-water supply pipe from freezing and bursting.
