PURPOSE:To prevent the indoor heating side from having a shortage in capability when a floor heating and indoor heating are performed by an oil burning hot water boiler. CONSTITUTION:The diagram shows the constitution of an oil burning hot water boiler 1 which can circulate hot water to a floor heater 2 for floor heating and fan convectors 3A, 3B for indoor heating. 4A is a boiler equipped with heat-exchangers 7a, 7b, 4B is a boiler equipped with a heat-exchanger 8, 5A, 5B are cisterns to store hot water, and 6A, 6B are hot water pumps to circulate the hot water. At specified locations on the entrance and exit sides of the heat- exchangers 7a, 7b, opening/closing valves 9-13 are provided. When the boilers 4A and 4B are operated at the same time, i.e., a floor heating and indoor heating are performed at the same time, the system is operated with the opening/closing valves 9, 10 and 13 being closed, and the opening/closing valves 11 and 12 being opened. By this method, the temperature of the hot water for the fan convectors 3A, 3B can be made higher. When a floor heating only, or indoor heating only is performed, the system is operated with the opening/ closing valves 9, 10 and 13 being opened, and the opening/closing valves 11 and 12 being closed. |
