Frequently Asked Questions
How does the JNOD B28DE provide instant hot water?
The B28DE features a 2.8L large capacity tank that maintains water at near‑boiling temperature. When you turn the tap, it delivers 98°C water instantly at a high flow rate of 2.2L/min — no waiting for a kettle to boil. It can produce up to 60 cups (250ml each) per hour, perfect for busy kitchens and home offices.
Is professional installation required?
Yes, we recommend installation by a qualified plumber or technician. The unit connects to your cold water line and requires a standard electrical outlet. Easy‑install instructions are included, and many customers have it fitted within an hour.
Does the B28DE work with filtered or RO water?
Absolutely. The JNOD B28DE supports integration with most RO systems and water filters. Using filtered water enhances taste and prolongs the life of the unit. The system is NSF certified for material safety, ensuring healthy water for you and your family.
How do I clean and maintain the dispenser?
Thanks to the patented non‑contact heating plate, the B28DE resists limescale buildup — no descaling needed! Simply wipe the exterior stainless steel faucet with a soft cloth. The internal tank is self‑cleaning; we recommend replacing the water filter (if used) every 6 months.
Is it safe to use around children and in offices?
Yes. The faucet includes a child‑lock mechanism that prevents accidental dispensing of hot water. Dual temperature sensors prevent dry heating, and the system has multiple safety protections against overheating and scalding. It’s ideal for family homes and workplace breakrooms.
What temperature settings are available?
You can adjust the temperature from 45°C to 98°C in 1°C increments, either on the touch‑screen faucet or remotely via the Tuya Smart app. This allows you to get the perfect temperature for baby formula (45–50°C), green tea (75°C), or black coffee (98°C).
Is the B28DE energy efficient?
Very efficient. It only heats water on demand and has an insulated tank to reduce standby heat loss. Compared to a traditional kettle that repeatedly boils excess water, the B28DE can save up to 20% on electricity for hot water preparation. Smart scheduling via the app further optimizes energy use.
What certifications does the JNOD B28DE hold?
The B28DE is internationally certified: CE (European safety), ETL (North American safety), NSF/ANSI 42 & 53 (material safety and water quality), WRAS (UK plumbing approval), and WaterMark (Australia). These ensure top‑tier quality, safety, and compliance worldwide.
How noisy is the unit during operation?
