This is a very convenient, easy to install little water heater. You don’t need special wiring because it only uses 12 amps and will work on a standard 15 amp breaker. Meaning you can just plug it into a standard wall plug. It’s small enough to put it in a place that’s very out of the way. With 8 gallons it will cover a load of washing dishes and maybe it will cover a quick shower if you set this to keep the water really hot and then split it with the cold water during use, but if you take long showers, this isn’t going to cut it. I can however, think of several places in which this would come in handy, especially in campers or for an off grid setup.
