AUTOMATICAL DETERMINATION APPARATUS OF HOT WATER WAITING TIME IN BOILER

PURPOSE: A device for automatically determining hot water waiting time in a boiler is provided to prevent speed of hot water tapping from slowing by determining the hot water waiting time according to a pattern of using the hot water through storing time for using the hot water in a memory device and to reduce unnecessary consumption of energy. CONSTITUTION: A device for automatically determining hot water waiting time in a boiler comprises a flowing water sensor(14), a memory device(13), and a central processing unit(10). The flowing water sensor senses on and off signals of a flow rate switch or flowing water according to usage of hot water. The central processing unit receives the on and off signals of the flow rate switch or the flowing water, measures time for using the hot water, and stores the time in the memory device. The central processing unit automatically determines the hot water waiting time based on the time for using the hot water stored in the memory device.
