Title: Heat storage system
Inventor: YAMAGUCHI KATSUHIKO
IPC: F02G5/00
Filed: 2002-10-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a heat storage system for dispersing a load on a pump.  <P>SOLUTION: The heat storage system operates a warm-up pump 18 in a warm-up stroke and does not operate it in a heat storage stroke. Alternatively, in the heat storage stroke, a heater pump 15 is operated to accelerate the collection of hot water. The collection of the hot water can also be accelerated by increasing the rotating number of a circulation pump 3. Since a great load is exerted on the warm-up pump 18 during warm-up stroke, the heat storage stroke is executed by another pump, whereby the operating frequency of the warm-up pump 18 is reduced and the life of the warm-up pump 18 is elongated.  <P>COPYRIGHT: (C)2004,JPO
