What it is

The Ariston 816556 is an 18" immersion heater with an integrated anode, used to heat the water stored in a domestic hot water cylinder. It is supplied under the Advanced Water brand and carries the manufacturer part number 816556. The anode sits with the element in the same assembly and provides sacrificial protection for the cylinder interior.

Before you order

  • Confirm that an 18" immersion length suits the cylinder boss and the clearance available above the cylinder.
  • Check the thread and boss size on the cylinder against the immersion heater being removed.
  • Confirm the electrical rating of the existing immersion circuit and its controls match the replacement being fitted.
  • Inspect the condition of the cylinder boss and surrounding area before fitting, as a corroded boss may need attention first.
