热水装置以及热水装置的异常通知方法
摘要：
本发明的目的在于在间接加热类型的热水装置中，抑制成本并恰当地检测出次级水回路的堵塞。热水装置(100)具备：初级水回路(27)，供在热交换器(21)中与制冷剂进行热交换而被加热后的水进行循环；次级水回路(28)，经由热交换器(23)与初级水回路(27)连接并供水进行循环；以及罐(26)，与次级水回路(28)连接，对在次级水回路(28)中循环的水进行贮存。热水装置(100)检测在初级水回路(27)中循环的水的温度以及贮存于罐(26)的水的温度，当在初级水回路(27)中循环的水的温度处于第1阈值以上并且贮存于罐(26)的水的温度处于第2阈值以下的情况下，发出表示次级水回路(28)产生了堵塞这一情况的通知。
摘要（英）：

An indirect-heating hot water apparatus is designed to correctly detect clogging in a secondary water circuit at low costs. A hot water apparatus 100 is provided with: a primary water circuit 27 in which water heated by absorbing heat from a refrigerant at a heat exchanger 21 circulates; a secondary water circuit 28 connected to the primary water circuit 27 via a heat exchanger 23, in which water circulates; and a tank 26 connected to the secondary water circuit 28, in which the water circulating in the secondary water circuit 28 is stored. The hot water apparatus 100 detects the temperature of the water circulating in the primary water circuit 27 and the temperature of the water stored in the tank 26. When the temperature of the water circulating in the primary water circuit 27 is at or above a first threshold and the temperature of the water stored in the tank 26 is at or below a second threshold, the hot water apparatus 100 issues a notification indicating that the secondary water circuit 28 is clogged.
