• Consistent heating performance

Always confirm the element length before ordering.

The included RDT thermostat helps regulate water temperature and ensures the immersion heater operates safely and efficiently.

The thermostat helps:

Common Reasons for Replacement

You may require a replacement immersion heater if:

• The cylinder is not producing hot water
