EcoSmart ECO MINI 4 4-Gallon 120V Electric Mini Tank Water Heater - Compact & Energy Efficient - Perfect for Small Bathrooms, Kitchen Sinks & RV Use

The Ecosmart mini water heater is a great choice for those sinks that take forever to get hot water. We had our plumber install it under our kitchen sink. The water in the kitchen would take at least 1 minute just to feel warm. It was annoying and wasteful. I stumbled upon these mini heaters on Amazon and decided to give the Ecosmart a try since it had the smallest dimensions. We placed it in the cabinet under our sink right next to the garbage disposal. It fits there well, and leaves behind enough storage space for dish soap, dishwasher pods, garbage bags, etc. The Ecosmart plugs into a regular outlet, and thankfully we already had a free one under the sink.The Ecosmart is very simple to use. It has one knob on the front that controls the temperature. That's it. Unfortauntely, the knob doesn't have any markings to let you know what temperature the water will be, so there will be a little trial and error test period needed. We have ours set to just a little bit past the center line. That gives us water that's very warm, but not scalding hot, and perfect for washing dishes and hands. The front of the unit has two indicator lights; power and heating.The set-up works amazingly well. Now when we turn on the hot water we get hot water in only a couple of seconds, and once the hot water in the Ecosmart's tank starts to deplete, in about 2 minutes, the hot water from the hot water heater has reached the sink, so there are only a few seconds where the water temperature drops a bit. The Ecosmart cycles on and off as needed to keep the water temperature in the tank within your set range throughout the day.All in all... a great solution for instant hot water.
