KENUOS 4-Gallon Under-Sink Water Heater | 1500W Instant Hot Water (110V/120V) Mini Tank

Fast, reliable hot water in compact spaces

The KENUOS 4-gallon under-sink water heater blends power with a small footprint, delivering hot water with remarkable speed. A 1500W heating element works with an upgraded L-shaped 316 stainless steel tube, achieving high thermal efficiency and heat transfer. In real-world use, expect hot water to be available quickly—as fast as 8 minutes from first activation—perfect for quick kitchen tasks or a fast hand wash during busy days.

With thoughtful design for multi-point use, this mini tank accommodates several needs without taking over your counter or cabinet space. Its 1/2 inch NPT connections are compatible with common fittings, and the unit includes a range of fittings to simplify installation.

Key capabilities include a robust 4-gallon capacity and a dual-outlet setup made possible by a 3-way diverter valve. This lets you feed two hot water points from a single heater. The model ships with two 24-inch hoses and adapters to handle diverse piping standards, so you can tailor the setup to your home or vehicle environment.

Safety and reliability are built in. The heater carries UL, CE, and DOE certifications, and a seam-welded, enamel-coated interior complements a corrosion-resistant exterior. A temperature and pressure relief valve, plus a mounting kit, are included to support secure, orderly installation.

Thermal insulation and a glass-lined interior reduce heat loss when the unit is idle, helping to maintain water temperature and conserve energy over time. The result is a compact heater that supports daily tasks—from rinsing produce to washing dishes in tight spaces—without sacrificing performance.
