Abstract

PURPOSE:To reduce the constituent subsystems and components, reduce the systems installation space, and facilitate the installation work by providing a burner for heating trace hot water, a trace hot water circulation pump and a trace hot water feed pipe and a return pipe. 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 heat exchanger 20 for trace hot water that heats has a heating burner 20a for trace hot water for heating the water in the reservoir tank 3 as the trace hot water and is connected to the hot water reservoir 3, a trace hot water circulation pump 21 that circulates the trace hot water, and a trace hot water feed pipe 22 and a return pipe 23 are provided. 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 function of the instant hot water supply and the prevention of freezing of the external piping can be realized. As the externally installed subsystems and components are reduced, the systems installation space can be reduced, and the installation work can be facilitated.
