Rinnai Water Heater Instantaneous Water Heater Model: RUS-V51YT (WH) Made in January 2018 This product was working before removal. It is being sold because it is no longer needed due to a move. While there is a sense of use associated with normal use, there have been no problems so far, and I think it can still be used. If anyone needs them, I will give away the piping and shower parts as a gift. Please check the photos.
