Ranein Gen II 2.5-Gallon Mini Tank Electric Water Heater – Instant Hot Water, Under-Sink or Floor Mounted (1440W, 120V)

Instant Hot Water Where You Need It

The Gen II 2.5-Gallon Mini Tank from Ranein brings warmth right to the tap. With a 1440W heating element and 120V operation, it stores pre-heated water so you enjoy fast warmth at kitchen sinks, utility basins, bathrooms, garages, RVs, or cabins—without a long wait.

Built for durability, the unit uses a premium 304 stainless steel inner tank with reinforced welded construction and a magnesium anode rod. This design resists corrosion, scale buildup, and high-pressure wear, helping maintain reliable performance year after year.

Smart insulation for savings

Triple-layer heat retention combines enamel coating, high-density foam, and reinforced steel housing. This setup can cut standby heat loss by as much as 30% and supports high-efficiency heating with an impressive overall performance rating.

Safety and ease of use

Six levels of protection cover temperature control and safety. Features include an adjustable thermostat, over-temperature safeguard (up to 185°F), high-pressure resistance (up to 150 PSI), dry-burn protection, IPX4 rating, and rapid leak detection. Designed with UL standards in mind for added household reliability.

Simple installation, versatile placement

Install in minutes using standard 1/2 NPT connections. Mount on a wall, on the floor, or on a shelf under a sink, then plug into a standard 120V outlet. Ideal for homes, offices, tiny homes, RVs, boats, workshops, or vacation cabins. Includes a 2-year tank warranty and 24-hour support.
