Hot water shouldn’t be a “schedule it and hope” situation—it should be immediate, consistent, and comfortable, even when multiple people are using the home. This 18kW electric tankless water heater is built to deliver on-demand hot water with smart flow control that automatically maintains your set temperature instead of letting it swing hot-cold during real use.

3 GPM maximum output, it’s designed for stable performance at 2–3 points of use, and when demand rises above capacity, it intelligently reduces flow slightly to keep temperature steady—so the shower stays comfortable instead of cutting out. Efficiency is a core advantage. Self-modulating technology adjusts power in real time based on water flow and incoming temperature, helping reduce wasted electricity.

When no hot water is needed, it drops into true standby. The wall-mounted design saves significant space compared to traditional tank heaters, making it ideal for utility rooms, closets, or tight mechanical areas. The unit includes a digital temperature display and supports remote temperature control through a compatible smart app, with monitoring features for water flow and usage insights.

Built for reliability, the internal layout is designed to reduce scale buildup and corrosion with a water-electricity separation approach, supporting long-term efficiency with minimal upkeep. Multiple safety protections are integrated, including leakage protection, overheat protection, and dry-fire protection, and the unit is ETL certified for added confidence.
