<p>PURPOSE:To easily obtain high temperature hot water by connecting a radiating system to a heat pump hot water system together with a heat exchange part, disposing a hot water feeding system passing through the heat exchange part, and also disposing water heaters at suitable positions of these systems. CONSTITUTION:In a state where a water heater 11 is not operated, hot water obtained by heat exchanging with a heat pump is circulated to a radiating system B to effect the room heating and additional heating of bath water. Further, hot water of the heat pump hot water system A can be supplied from a hot water feed part 10 by means of a feed hot water system C. Further, if a hot water heater 11 is operated, it is possible to feed high temperature hot water. By this construction the temperature of hot water of the heat pump hot water system A can be decreased to a value which is less than the temperature of high hot water, and hence the heat pump efficiency can be improved and highly hot water can be obtained.</p> |
