Abstract (en)

[origin: EP4130601A1] To provide a hot water generator that can be connected to a crossover pipe for supplying hot water, extending to a hot water supply place, without loosening a screw-in pipe joint of a circulation pump and inducing leakage caused from the loosing of the screw-in pipe joint of the circulation pump, a hot water generator (1) includes a housing (51) that has a joint insertion hole (77), a pump (36) that includes a pump-inlet pipe joint (72) and a pump-outlet pipe joint (73), and a hot-water pipe connection joint (48) that is fixed to the pump-outlet pipe joint (73) and protrudes to an outside of the housing (51) through the joint insertion hole (77), and is connectable to a hot water pipe (47) outside the housing (51), which sends hot water to a hot water supply place.
