Over Sink Water Heaters

Similarly to under sink water heaters, over sink water heaters supplement your existing water supply. If your sink is too far away from the boiler, you may find it useful to install an over sink water heater. Some can be plumbed in to your existing supply, but many have a tap connected to the unit that dispenses water directly.

Over 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.
