After living for 3 years with a 120 volt, 4 gallon water and three minute showers. This 8 gallon version was a real treat. For many people, even a six to eight minute shower would be not be good enough. Any more capacity would mean adding an electrical 240 volt connection and moving the plumbing around to make room, neither of those options we were willing to do. This VEVOR Electric 8 gallon, 120 volt Mini-Tank boiler Water Heater heats enough water for washing dishes by hand and to bathe, yet not much more. It is not going to produce enough hot water to supply a full loaded dishwasher or a washing machine load. Two minor gripes worth mentioning. 1. I chose this particular model because of a light that came on when water was being heated. The light is too dim to be seen during the day. 2. The manufacturer did not include the plug, so I had to buy it myself in order to plug it in.
