Onnline electric heating element 1.4 kW 5/4" TSE model W-082

Onnline electric heating element 1.4 kW 5/4" TSE model W-082 is a compact immersion heater designed to heat water and other compatible liquids in tanks and boilers. The unit provides 1.4 kW of electrical heating power and features a 5/4" TSE threaded connection for straightforward installation or replacement in systems that require this thread size. Constructed for domestic and light industrial use, this heating rod offers a space-saving, in-line heating solution where reliable low-to-moderate power is needed.

Advantages

The heating element delivers consistent thermal output at 1.4 kW while occupying minimal space, making it suitable for confined installations. Its standard 5/4" TSE threaded connection simplifies mounting and replacement without the need for extensive modifications. The design is oriented toward direct immersion in liquids for efficient heat transfer and stable operation in typical hot-water and boiler applications.

Suitable for

• Heating water in domestic hot-water tanks and small boilers
• Replacement of existing 1.4 kW, 5/4" threaded immersion heaters
• Light industrial or workshop tanks requiring low-to-moderate heat input
• Compact systems and installations with limited space for heating elements

Key specifications

• Power: 1.4 kW
• Thread type and size: 5/4" TSE threaded connection
• Mounting: Immersion (in-line) heater suitable for direct installation into tanks or boilers
• Intended medium: Water and compatible liquids
• Application: Domestic and light industrial heating

How to use

Before installation, ensure the tank or boiler is drained and isolated from power. Verify that the 5/4" TSE thread on the vessel matches the heater connection and that the immersion depth is appropriate for effective heat transfer. Fit the heating element into the threaded port and secure it to the recommended torque for the fitting material, using appropriate sealing where required. Refill the tank, restore electrical supply through a correctly rated circuit and protection device, and monitor the first heating cycle to confirm normal operation and absence of leaks.

Usage recommendations

Use a thermostat or temperature controller compatible with 1.4 kW load and install overcurrent protection and residual current device (RCD) according to local wiring regulations. Avoid energizing the heater when not fully immersed to prevent overheating. For safe long-term operation, periodically inspect the element and connections for corrosion or scale buildup and follow manufacturer guidance for maintenance.
