Abstract

PURPOSE:To reduce the constituent subsystems and components, reduce the systems installation space, and facilitate the installation work by providing a trace hot water feed pipe and a return pipe that are connected to the reservoir tank, and a trace hot water circulation pump. CONSTITUTION:In order to heat and keep warm an outer hot water feed pipe 15 and an outer feed water pipe 13 that are connected to the hot water reservoir tank 3, a trace hot water circulation pump 20 and a trace hot water feed pipe 21 and a return pipe 22 are provided to circulate the trace hot water which is drawn from the hot water stored in the reservoir tank 3. In this manner, only by building the trace hot water circuit consisting of compact constituent subsystems into the hot water type water heater unit which is connected with the external piping for tracing that joins the outer hot water feed pipe or the outer feed water pipe, the functions of the instant hot water supply and the prevention of freezing of the external piping can be realized without recirculating the hot water. Further, as the externally installed subsystems and components are reduced, the systems installation space can be reduced and the installation work is facilitated.
