Abstract

PURPOSE: To provide a highly concentrated hot-water circulation system with a longer life wherein a storage body is made up of stainless steel superior in working property and abrasion resistance and copper ion concentration in hot water is held to 10ppm or less.
CONSTITUTION: The storage body 1a is formed with ferrite stainless steel of superb working property and abrasion resistance which consists of 18.5W19.5 for Cr, 1.8W2.5 for Mo, 0.1W0.5 for Ti, 0.2W0.5 for Nb, Si<0.2, Mn<0.2 and C+N< 0.02, all in weight percentage, and Fe and other inevitable impurities. A copper ion removal unit 5 is inserted near the return port of the storage body 1a of the water heater 1 fitted to the hot water supply pipe 4 to hold copper ion cocentration in the storage hot water to 10ppm or less. By so doing, the acceleration of abrasion of the storage body 1a can be checked appreciably, thus ensuring a longer life of concentrated hot water circulation system.
