The Strom 15-Litre Unvented Undersink Water Heater (Generation 2) delivers a highly efficient, localised hot water solution for isolated basins, commercial utility sinks, and remote washing areas. Powered by a robust 2.5kW built-in immersion heater, this compact unit provides immediate mains-pressure hot water without the extensive pipework routing required by centralised boiler systems. Encased within a durable ABS shell, the heater features 25mm of high-density thermal insulation, significantly reducing standing heat loss and ensuring exceptional energy retention between draw-offs.

Engineered with simplicity and safety in mind, the SEUS15L2 model incorporates fully integrated safety controls and a replaceable magnesium anode to actively prevent internal tank corrosion over prolonged operational cycles. Measuring just 385mm in height and width, its low-profile architecture ensures seamless integration directly beneath standard cabinetry. The system utilises standard 1/2-inch male thread fittings for straightforward hydraulic connections, allowing installers to rapidly mount the unit using the supplied wall bracket system before establishing a hardwired 230V electrical feed.

Q: What are the physical dimensions of this undersink heating unit?
A: The compact heater measures 385mm in height, 385mm in width, and has a depth of 310mm, perfectly suited for standard undersink cabinetry.

Q: Does the system require a dedicated expansion vessel?
A: As an unvented water heater, specific installation scenarios may necessitate external expansion controls depending on incoming mains pressure and existing pipework volume.

Q: What type of hydraulic connections does the unit feature?
A: The appliance is equipped with standard 1/2-inch male BSP thread fittings for rapid and secure plumbing connections.

Q: How is the internal tank protected against long-term corrosion?
A: The tank is safeguarded by a factory-fitted, replaceable magnesium sacrificial anode which neutralises corrosive elements within the stored water.
