What it is

The Andris Lux EP 15L U/Sink 3kW is an undersink water heater from the Ariston Andris Lux EP range, covering a 15 litre stored hot water capacity with a 3 kW heating element. The unit is designed to be installed below a sink or within a base unit, providing local stored hot water where a cylinder run is impractical. It is listed within the Ariston water heater product group.

Signs this part needs replacing

  • Hot water runs cold or cools quickly after a short draw-off
  • Water at the tap is lukewarm despite the unit being powered
  • Visible water weeping or dripping from the unit body or connections
  • The safety cut-out has tripped and will not reset
  • The unit is noisy or rumbling during the heating cycle

Before you order

  • Confirm the required stored capacity matches the 15 litre rating
  • Check the electrical supply and circuit protection are suitable for a 3 kW load
  • Measure the space available under the sink, including clearance for connections and pipework
  • Verify the existing unit is from the Ariston Andris Lux EP range before ordering
