Instant hot water for handwashing - thanks to on-demand heating

Water is heated on demand rather than stored, with the heater activating when the start control is used. On-demand operation makes hot water available even where only a cold mains supply exists.

Provides immediate warm water at basins without a separate hot-water feed, ideal for wash stations and utility sinks.

Simple control and operation - with a single start/stop and temperature selector

A single control handles both power and temperature selection, reducing the number of user adjustments required. The combined function also simplifies wiring and user interaction.

Makes everyday use straightforward for family members and visitors, with clear settings for quick temperature changes.

Quick retrofit and compact fit - with direct replacement design and space-saving casing

Designed as a direct replacement to the Triton T30I, matching mounting points and footprint for like-for-like swaps. Compact casing allows installation in small cupboards or behind basins.

Suits upgrades without major rework and fits into limited spaces where a larger heater would not.
