The immersion heater is fitted with metal sheathed, rod elements and is constructed to a robust design. All models are fitted with a water-tight enclosure rated to IP66 suitable for indoor or outdoor applications or for use in damp or humid conditions. Heaters are suitable for either horizontal or vertical screwed fixing. To avoid localised boiling or air locks, care should be taken to ensure that the cold zone extends beyond any neck piece.
All standard models are supplied with a factory fitted control thermostat, with a range of 40 – 88 degrees C (rated 20 Amps), and high limit thermostat, with a range of 45 – 95 degrees C (rated 16 Amps).
