Under sink water heaters provide instant hot water by drawing cold water from your supply and storing it in the holding chamber. Then, when you need it, it is moved from the holding chamber, over a heated element to deliver instant hot water. While this is happening, more cold water is drawn into the holding chamber for the process to repeat.
