Dexpro Delux Under Sink Vented Water Heater 5ltr

Delux Vented under sink water heaters are ideal for use in light commercial or domestic applications where supply to a single sink is required for light hand/dish washing. Its modern design and the use of carefully selected materials and an improved manufacturing process ensure high quality.

Energy-saver mode/reduced energy consumption: Greater energy savings are possible if the water temperature is set to a maximum of +/- 55 C. This also reduces the risk of damage to the water heater. Once a setting is selected the indicator light will illuminate to signal the element is heating up to the desired temperature. When the eon light extinguishes this means the desired temperature setting has been achieved.
