Ariston Instant Electric Water Heater — 11.25 kW (International Warranty)

Enjoy hot water on demand with the Ariston Instant Electric Water Heater (11.25 kW), a compact, tankless solution engineered for fast heat-up and stable output. Unlike storage heaters, this unit delivers hot water the moment the tap opens, minimizing wait time and cutting standby energy losses. Its streamlined footprint fits neatly beside the point of use—ideal for bathrooms, showers, guest WCs, or kitchen sinks where space is at a premium and response time matters.

The robust 11.25 kW heating capacity supports a comfortable single-point application (e.g., one shower or basin), with flow adjusted by inlet temperature and water pressure. A wall-mounted layout keeps pipe runs short to reduce thermal losses, while the tankless design avoids limescale buildup associated with standing hot water. For daily convenience, the heater’s intuitive controls let you fine-tune temperature to match the season, delivering consistent comfort through typical mains conditions.

Built with safety and reliability in mind, the unit typically integrates overheat protection, a pressure relief element, and electrical safeguards appropriate to local standards. The exterior is easy to wipe clean and blends into modern spaces with a clean white finish. Backed by an international warranty, Ariston’s service network supports installation and after-sales care. For best results, consult a qualified electrician/plumber to size the circuit, breaker, and cable cross-section correctly and to verify local voltage (commonly ~230 V / 50 Hz, region-dependent).
