What it is

The Heatrae Sadia 7037726 is a combined thermostat and thermal cut-out assembly with an integral control knob, used to regulate water temperature in Heatrae Sadia Multipoint water heaters. The thermostat switches the immersion element to hold the set temperature, while the thermal cut-out provides a safety trip if the cylinder overheats. It is supplied for the 30L and 50L 3kW Multipoint models.

Signs this part needs replacing

  • No hot water even though the immersion element is receiving power
  • Water running hotter than the set temperature, or the cylinder overheating
  • Thermal cut-out tripping repeatedly and needing to be reset
  • Temperature control knob loose, stiff or failing to alter the setting
  • Erratic or inconsistent water temperature at the outlet

Before you order

  • Confirm the cylinder is a Heatrae Sadia Multipoint 30L or 50L 3kW model
  • Check whether the unit is installed horizontally or vertically
  • Verify the existing part number 7037726 against the component being replaced
  • Isolate the electrical supply before removing or fitting the assembly
