<p>PURPOSE:To provide an electric water warmer which can always utilize high temperature hot water by means of a low power, by a method wherein hot water heated by a heater situated in a first container is stored in a second container with the aid of a pump. CONSTITUTION:When a temperature by a temperature sensor 3 is below a heat accumulation completion temperature, for example, 80 deg.C, a heater 2 for heating is made to heat water in a first container 1 to 80 deg.C. When water temperature is increased to 80 deg.C or more, the temperature sensor 3 detects the temperature, a signal is sent to a control means 17 to drive a pump 9, water, contained in the first container 1 and heated to 80 deg.C, is fed to a second container 5, and water 7 in the second container 5 is fed to the first container 1 by a quantity equivalent to a quantity of water fed from the first container 1. The fed water is heated by the heater 2 for heating to 80 deg.C again, and the water heated to 80 deg.C is returned to the second container 5. The circulation enables storage of hot water having a temperature of 80 deg.C in the second container 5.</p> |
