The JNOD KJ features a unique high-quality ABS front cover that is water splashing proof, corrosion resistant, and aging resistant. Designed for long-lasting durability in humid kitchen environments.
Safety is built into every layer: electricity leakage protection, anti-scalding protection, over-pressure and overheat protection, plus complete water and electricity isolation. The patented heating element ensures zero risk of electrical contact with water.
Easy to install with versatile mounting options. The KJ can be installed either above the sink or hidden underneath, making it suitable for any kitchen layout.
Despite its compact appearance, the KJ delivers an unlimited supply of hot water. Installed at the point of use, it eliminates waiting time and standby heat loss.
Fully protected against water jets from any direction with IP25 waterproof rating—ideal for kitchen and bathroom installations where splashing is common.
The LED digital display shows real-time working conditions including power status and temperature. The display can be digitally flipped for upside-down installation, ensuring easy readability regardless of mounting position.
Built-in fault auto-detection technology continuously monitors system performance. When a failure occurs, the corresponding error code is automatically displayed for quick troubleshooting.
Integrated ELCB (Earth Leakage Circuit Breaker) provides advanced electrical safety. Within 0.1 seconds of detecting a leakage, it simultaneously cuts off both live and neutral lines, eliminating shock risk.
The KJ actively checks that the ground wire is properly connected before operation. This earth detection function ensures your installation meets safety standards and provides an additional layer of protection.
JNOD specializes in electric tankless water heaters, an advanced category of electric water heater designed for on-demand hot water. Driven by technological innovation, our team of seasoned technicians has developed multiple proprietary patents for instant electric water heaters and under sink water heater applications. We strictly adhere to the ISO international quality management system and manufacture all core components in‑house, ensuring consistent performance and durability across our product lines.
Our range of instant water heaters, including kitchen water heaters and under sink water heater models, holds internationally recognized certifications such as CCC, CB, CE, and ETL (UL standard). These credentials verify that every electric tankless water heater and electric instant water heater meets rigorous global standards for electrical safety, energy efficiency, and reliable operation. With these certifications, JNOD provides peace of mind for residential and commercial users seeking a dependable electric water heater tankless solution.
Yes, the JNOD KJ is designed for standard 220–240V household circuits. It has a maximum power of 3.5kW, which draws about 16A. We recommend having a dedicated circuit with a 20A breaker and ensuring the wiring is at least 2.5mm² (14 AWG). Always consult a licensed electrician to confirm your home’s electrical system is compatible.
Absolutely. The KJ model delivers instant hot water at a flow rate of approximately 2–3 litres per minute (depending on inlet temperature). It’s perfect for washing dishes, rinsing vegetables, or preparing instant meals. For continuous use, the tankless design ensures you never run out of hot water.
The unit activates automatically when water flow reaches 0.3 litres per minute. It works with standard municipal water pressure (0.04–0.6 MPa). If you live in an area with very low pressure, a booster pump may be needed.
Safety is a top priority. The KJ features ELCB (Earth Leakage Circuit Breaker) that cuts off power within 0.1 seconds if a leakage is detected. It also has IP25 waterproof rating, over‑pressure protection, and anti‑scalding control. The patented cast‑aluminum heating element isolates water from electricity completely.
While the unit comes with a simple wall‑mount bracket and can be installed with just one screw, we strongly recommend hiring a qualified electrician or plumber to ensure proper electrical connection and water supply. Incorrect installation may void the warranty.
Thanks to the multi‑layer heating chamber design, scale buildup is greatly reduced. In most areas with normal water hardness, no regular descaling is needed. If you have very hard water, an occasional check by a professional is advised to maintain peak performance.
The touch panel allows you to set the outlet temperature from 30°C to 55°C. The digital display shows both inlet and outlet temperatures, and the unit maintains your chosen temperature within ±1°C for consistent comfort.
Yes. With 98% thermal efficiency, the KJ only heats water when you turn on the tap—no standby heat loss like traditional storage heaters. This makes it extremely economical for kitchens in Southeast Asia, where hot water is needed only briefly multiple times a day.
