Abstract

PURPOSE:To boil up hot water with an electrical power in a specified time range of low electrical charge by a method wherein an amount of remaining hot water is compared with a predetermined amount of hot water and a calculation means to take a transfer time between an electrical energization of an upper heater and an electrical energization of a lower heater is provided. CONSTITUTION:A calculation means 9 discriminates that an amount of remaining hot water is not much, but low and then an upper heater 7 is electrically energized at once. With such an arrangement, hot water 23 placed over a mixing layer 25 within a tank 3 is heated. When a boiling-up condition of the hot water is detected by an upper temperature sensor 2c, an electrical energization for the upper heater 7 is turned off. After this operation, in the event that there is a small amount of remaining hot water, it is sometimes found that a transfer time is zero, so that it is discriminated whether the transfer time is present or not. If the transfer time is zero, a lower heater 5 is electrically energized at once. In the event that there is a certain transfer time, the transfer time is read out from the third memory 15, drives a stored timer and after elapsing the transfer time, the lower heater 5 is electrically energized. A mixing layer 25 and water 24 in the tank 3 are heated.
