Installation & Sizing Advice
Important Fitment Note: This is a 27-inch (686mm) immersion heater designed specifically for vertical, top-entry mounting into domestic hot water cylinders. Verify your cylinder has at least 700mm of clear internal vertical depth before ordering; this unit is not suitable for horizontal side-entry bosses. The thread is a standard UK 2 1/4" BSP (approx. 65mm OD). Electrical wiring must be completed via a 13A double-pole switched fused spur by a qualified person in accordance with current IET regulations.
