What it is

The Atlantic Nanto Lite 15L Under Sink is a 15 litre Atlantic water heater intended for installation beneath a sink, delivering hot water at the point of use rather than from a remote store. It belongs to the Atlantic Nanto Lite range and is listed against the Atlantic Water Heaters appliance group. The unit is identified by part number AH821549.

Signs this part needs replacing

  • No hot water delivered at the outlet the heater serves
  • Water pooling beneath the unit or damp around its connections
  • Repeated operation of the safety cut-out
  • Reduced hot water recovery or lower outlet temperature than expected
  • Visible corrosion or heavy scale on the casing or fittings

Before you order

  • Confirm 15 litres is the correct capacity for the hot water demand at the outlet
  • Check there is sufficient space beneath the sink for the unit and its pipework
  • Match part number AH821549 against the unit being replaced
  • Confirm the available services and controls are suitable for the installation
