Automatic Boiler redvees Cost Price using briquettes or oil

摘要

PURPOSE: An automatic boiler system is provided to reduce the fuel cost of an oil boiler by connecting the oil boiler to a briquette boiler through a hose such that the oil boiler and the briquette boiler are selectively used depending on the weather. CONSTITUTION: An air valve(1), a temperature gauge(2) and a safety valve(3) are installed at a header of a supplying pipe of a briquette boiler so as to eject air, to maintain the room temperature and to prevent a pipe from being overheated. A circulation pump(4), an automatic air valve(5) and a general valve(6) are installed in a circulating pipe. An oil boiler circulation pump is installed instead of a briquette boiler circulation pump, so hot water is easily circulated and air is automatically ejected. A hot water supplying pipe is connected to a circulating pipe through a T pipe, so that the oil boiler and the briquette boiler are selectively used.
