This item will not last that long. I use these in a jail, as a hot water supply in the modules for their instant coffees, teas, and ramen products. It is kept in a covered metal box, out of sight, under the module sink. It is on 24 hours a day 7 days a week, 365 days a year. At that pace it will last about one year before it will require maintenance. I keep a supply of parts removed from broken units and can repair them for about three years before they rust through. For me they are the answer, and cost effective.
