KENUOS Under Sink Instant Hot Water Heater – 2.5-Gallon, 1500W, LED Display, 1/2" NPT, 3-Way Diverter

The KENUOS 2.5 gallon under-sink instant hot water heater is engineered to bring hot water exactly where you need it, without crowding your space. Its compact footprint fits neatly under most sinks or in tight utility areas, while the bright LED display keeps real-time temperature at a glance. With standard 1/2" NPT connections and included fittings, setup is straightforward for both home kitchens and mobile installations like RVs.

Speed, safety, and smart control

• Rapid heating with 1500 watts, so hot water is ready when you are.
• L-shaped heating tube expands the heating surface for efficient warming.
• Typical delivery time to hot water ranges from 4 to 6 minutes.

Safety and durability are built in. The unit uses an ABS shell with a stainless steel seamless welded tank for strength and corrosion resistance. It’s designed to withstand higher pressure up to 116 psi and includes a T&P valve to guard against unsafe conditions. The product also carries UL certification, giving a trusted safety standard for daily use.

Smart temperature control and insulation

• Adjustable temperature from 86°F to 149°F with a simple knob, so you can dial in comfort levels.
• An integrated control chip maintains the set temperature and enters a heat-preservation mode when idle.
• Non-toxic flame-retardant polyurethane foam insulation helps extend hot water duration and reduce heat loss.

The design emphasizes practical installation and flexible placement. The compact form (approximately 17" x 17" x 16" of installation space) supports wall-mounted or floor-mounted setups. It operates on standard 110–120V mains with a recommended 15A circuit, and it includes a T&P valve, a 3-way water diverter, two conversion pipes, and a water guide pipe for straightforward hookup.

Versatile use and a patent-aware design

Ideal for homes, small apartments, RV kitchens, food trucks, and cabinet-backed spaces, the unit’s 1/2" NPT fittings and compact footprint help you tap hot water where you need it.
