I installed this tankless water heater to provide hot water to the sink in my outdoor kitchen 10 years ago. It has always worked well to have hot water for hand washing, rinsing dishes or food, etc. It's installed in the Houston Texas area so the water gets too hot to touch in the summer and plenty warm in the winter. The cold water feed comes from an outside faucet tapped to send water through a pipe under ground to the counter. In the severe freeze of February 2021 the water heater ruptured, as did every tankless water heater as I understand because there was no power during the freeze. If I had disconnected it and brought it indoors and drained it it might have survived. I replaced it with another identical water heater.It is compact and easy to install. I like that you mount a mounting plate on the wall then connect the cold and hot water flexible lines, pressure test it, then snap it into place on the mounting bracket and then connect the electrical connection. It is easy to dismount from the mounting bracket, too.I had it installed in a fairly cramped space under the sink next to a Gould under sink self contained pump. I also installed a garbage disposer to help handle solids going out the drain.
