LOVE IT

I ordered this water heater after doing a lot of research and reading of reviews. When I finally decided to buy it the store I wanted to purchase from were out of stock. So I found tje manufacture website. Ordered June 27 with no shipping fee. Was delivered July 11. We installed it easily and have been using it for about 2 weeks now and I LOVE IT. Love that someone can shower and do dishes or laundry at the same time. The programmer has such a long chord that I am able to program from inside the house. I love that I can use both hot and cold water without one or the other cancelling the other out. I HIGHLY recommend this product. I live 6 months out of the year in a mobile home at a camp ground and am extremely satisfied with this water heater.
