PROBLEM TO BE SOLVED: To attain the further improvement of heat exchange efficiency by enlarging a heat transfer area, reducing a heat loss, and providing uniform heat exchange.;SOLUTION: A multiplex pipe 62 of a first water-refrigerant heat exchanger 9 of the this pump type hot water supply heating system is composed of three copper heat exchange pipes 70 (each composing a refrigerant passage 9A) passing a refrigerant through interiors, a copper heat transfer tube 71 covering and holding the heat exchange pipes 70 in separated states, and a copper outer pipe 73 arranged around the heat transfer pipe 71 with a slight interval between to form a water passage 9B so as to pass hot water between the copper outer pipe and the heat transfer pipe 71.;COPYRIGHT: (C)2006,JPO&NCIPI
