Abstract

PURPOSE: To save energy and decrease erosion by connecting a timer to a circulation pump, the timer being set so as it cannot lower the temperature of hot water at every branching point for a water supply plug down to an inconvenient value, and controlling the ON-OFF of the pump.
CONSTITUTION: On the discharge side of a circulation pump 2 connected to the upper part of a hot water tank 1, a water sending pipe 4 is provided between the pump 4 and a cock 3 on each floor, and a water return pipe 5 between the cock 3 and the tank 1. A heat source 6 is housed in the tank 1. The pump 2 is connected with a timer 9, which is set at a precalculated time required for the temperature of hot water on the discharge side of the pump 2 to drop down from a favorable value to a value slightly above an inconvenient one, so that an intermittent operation of the pump 2 can be obtained within a preferable range of temperature. A thermostat 10 is arranged on the discharge side of the pump 2 for switching ON when the current water temperature drops under the preferable range to a prescribed degree, and switching OFF similarly when the current water temperature rises over the preferable range. As a result of the intermittent operation within the preferable range of temperature, energy saving and decrease in water leakage due to erosion can be expected.
