What it is

The Ariston 65112038 is a mixing valve used on Ariston Kairos MACC unvented hot water cylinders. It blends hot stored water with cold mains water at the outlet to deliver a controlled delivery temperature. It is a serviceable component within the cylinder's hot water outlet assembly.

Signs this part needs replacing

  • Delivered hot water temperature drifts or fluctuates at the tap
  • Water runs consistently too hot or too cold regardless of cylinder setpoint
  • Temperature at the outlet cannot be held steady during draw-off
  • Scale or debris build-up at the valve affecting blending performance
  • Visible leakage or weeping from the valve body or its connections

Before you order

  • Confirm the cylinder model and code against the fit list above
  • Check the existing valve part number matches 65112038
  • Verify the cylinder is a Kairos MACC Cd1 or Cd2 unit before ordering
  • Confirm the fault lies with the mixing valve rather than the cylinder thermostat or controls
