2000W SUS316 Immersion Heater Core

This replacement heater core measures approximately 22 cm (8.66 in) in total insert length and weighs around 305 g (10.76 oz). It is constructed entirely from high-grade SUS316 stainless steel, offering superior resistance to thermal cycling and UK hard water mineral deposits compared to standard SUS304 or copper elements. The core features a 1-1/4 inch threaded base designed for direct, secure installation into standard domestic hot water cylinder ports. Rated at 2000W, it delivers rapid reheat performance and consistent temperature maintenance — provided it is used with appropriately sized storage tanks and compatible thermostatic controls.
