Immersion Heater 6kW 230V – G1½" 316L Stainless Steel, 460mm Immersion Depth

Product Overview

This 6kW immersion heater is designed for demanding industrial and commercial liquid heating applications where reliability, durability, and accurate temperature control are required. The heater features a G1½" stainless steel threaded fitting combined with Incoloy 800 heating elements, offering excellent resistance to oxidation, scaling, and high operating temperatures.

With a 460mm immersion depth, this heater is well suited for medium-depth tanks, vessels, calorifiers, and process systems where efficient and consistent heating is required.

The heater is supplied with a 100mm × 100mm plastic terminal box housing a combination control thermostat (30–70°C) and an integrated pilot light, providing clear visual indication of operation and safe temperature regulation.

Installation is simplified with an M20 × 1.5 cable gland and a 2-metre pre-wired 3 × 2.5mm² cable, making the unit ready for connection to 230V single-phase power supplies.

Installation Notes

• Installation must be carried out by a qualified electrician or competent engineer.

• The heater must be fully submerged before energising to prevent element damage.

• The combination thermostat provides both operational temperature control and safety cut-out protection.

• Ensure electrical supply protection and cabling are suitable for a 6kW single-phase load.

• Confirm the heated fluid is compatible with Incoloy 800 heating elements.
