Vented Point-Of-Use Oversink Water Heater With Telescopic Spout & Adjustable Thermostat 7 Litres 3.0kW 240V.

Typically installed directly over the sink. Ideal for light commercial duty such as washing cups and dishes.

Water can be supplied either directly from the mains or from an elevated cistern or feed tank (a minimum head pressure of 4 metres is required).

Supplied with an inlet valve that, when opened, allows the mains cold water supply to enter the heater and displace the hot water stored in the cylinder. As the valve controls the displacement, the outlet is open to atmosphere so that when the unit heats up, the expanded water is allowed to drip from the spout into the basin.

No other outlet should be used in conjunction with this type of product.
