What it is

The Heatrae EY311E is an immersion heater element combined with a TSD thermostat, produced by Heatrae Sadia for the R Series range. It heats stored water directly within the cylinder, and the integral thermostat controls the water temperature.

Before you order

  • Confirm the R Series model of your water heater matches the R Series designation listed for this part.
  • Check the existing immersion heater and thermostat assembly to confirm it is the EY311E before ordering.
  • Ensure the cylinder is isolated and drained before any replacement work is carried out.
