Ariston Europrisma EP10UR 3kW 10 Litre Under Sink Water Heater

The Ariston Europrisma EP10UR 3kW under sink water heater is a 10 Litre technologically advanced, versatile water heater. This water heater is ideal for localised use to heat mains water efficiently.

Often used in small business units where it is impractical to install a large boiler system or extend any existing hot water system. In commercial washroom settings, it is often installed within a vanity unit and is used to supply hot water through a single or multiple TMV3 valves to basin mounted mixer taps. Producing 10 Litres in just 17 minutes of reheat time (at 50 degrees) this is a super efficient and functional under counter or sink water heater.

When Do You Need to Use The Ariston Europrisma Expansion Kit with an EP10UR?

When water is heated it expands, so an allowance must be made for the extra volume that is needed for hot water. Current Water Regulations allow unvented water heaters with a capacity of 15 litres or less to accommodate the expansion of water that occurs during the heating cycle in the system pipework. But this means that you need sufficiently long pipework run to achieve this. To achieve this the pipework between the last cold water draw off and the water heater must be of sufficient volume to accommodate the expansion. For 15 mm pipe plumbing this distance of pipe needs to be at least 2.8m and in 22 mm pipe plumbing this distance must be at least 1.5m.

• Ariston Discharge Tundish (Kit C) for more information including when you need a discharge tundish please click here.

If you do not have a sufficiently long pipe run you will need to install an Ariston Europrisima expansion kit (Kit A) with non-retun valve (non-return valve is included with the Kit A expansion kit). If the mains water pressure may exceed 3.5 bar a pressure reducing valve (Kit B) should also be installed.

We do however recommend you use a Discharge Tundish (Kit C) with all installations but for further information on this or the other configurations please see the download forms below.
