• Retrofit or replacement of existing 1/2" immersion heaters

Key specifications

• Power output: 900 W
• Thread size: 1/2" threaded fitting for direct installation
• Temperature control: integrated adjustable thermostat
• Design: immersion heating element for liquids
• Typical application: single-phase domestic and light commercial heating of liquids

How to use

Install the heating element into a compatible 1/2" threaded port on the tank or vessel according to local electrical and plumbing regulations. Ensure the element is fully submerged in the liquid before energizing to prevent dry heating and potential damage. Connect to a suitable single-phase supply with appropriate protection (circuit breaker or fuse) and earth connection. Adjust the integrated thermostat to the desired setpoint and monitor during initial operation to confirm stable temperature control.

Usage recommendations

For safe and reliable operation, verify compatibility of the vessel material and thread sealing method, use a qualified electrician for electrical connections, and avoid running the element outside of liquid. Periodic inspection for scale buildup and electrical integrity is advised in hard-water environments.
