A first circulation channel (14) connects a first heat demand part (401) and a first supply heat exchanger (11) with its forward route and return route. A supply channel (15) and a discharge channel (17) are connected to a first heat accumulation tank (16). The first heat accumulation tank (16) accommodates a second heat medium (10) heated in the first supply heat exchanger (11) and supplied via the supply channel (15). A heat accumulation switching valve (19) performs a changeover operation of communication of the second heat medium (10) serving as hot heat or cold heat flowing from the first supply heat exchanger (11) and supplied to the first heat demand part (401) without branching to the supply channel (15), and communication of the second heat medium (10) serving as hot heat or cold heat branching to the supply channel (15) and supplied to the first heat accumulation tank (16). A heat-accumulating hot-water-supplying air conditioner (100) is operated at the first temperature when the second heat medium (10) from the first supply heat exchanger (11) is to branch to the supply channel (15), and at the second temperature lower than the first temperature when the second heat medium (10) is not to branch to the supply channel (15). A second circulation channel (23) is provided to allow circulation independently of the first circulation channel (14), and connects the first heat accumulation tank (16) and a second heat demand part (501) which requires hot heat for hot water supply or bathtub preheating, with its forward route and return route.

Apparatus and method for heating/cooling buildings and other facilities. An elongate pipe filled with water or other fluid medium forms a thermal gradient header having temperature zones that are progressively warmer towards one end and cooler towards the other. Multiple heating/cooling systems are connected to the header so as to draw fluid from zones that are closest in temperature to the optimal intake temperature of each system, and to discharge fluid back to the header at zones that are closest to the temperature to the optimal output temperature of each system, allowing each heating/cooling system to take advantage of the thermal output of other systems. The pipe forming the thermal gradient header may be routed back and forth in the facility to define a series of legs containing the different temperature zones. A boiler or other source may supply makeup heat to the thermal gradient header, and excess heat may be sent from the header to a ground field or other thermal reservoir for later use.
