What it is

The Ariston 816557 is a 3kW, 240V heating element used in Ariston Protech hot water cylinders. It heats the stored water in the cylinder, operating under the control of the cylinder's thermostat. It is a service part for the Protech range of direct and indirect cylinders.

Signs this part needs replacing

  • No hot water from the cylinder despite the programmer and thermostat calling for heat
  • The element trips the RCD or circuit breaker when the cylinder is powered
  • Water is only lukewarm, or the cylinder takes far longer than normal to recover
  • Continuity or resistance testing across the element terminals shows an open circuit
  • Visible scale, corrosion or blistering on the element body

Before you order

  • Confirm the cylinder model and Protech edition against the fit list above
  • Check the rating plate on the cylinder to confirm the element rating and voltage
  • Confirm whether the cylinder is direct or indirect, as the fitment differs across the range
  • Isolate the electrical supply to the cylinder before any inspection or replacement work
