Agust Instant Electric Water Heater – 110V/120V, 2.5–3.0 Gal Under-Sink Tank, Compact Point-of-Use

Meet the Agust instant electric hot water heater, designed for compact spaces where traditional hot water lines are hard to reach. With a small 2.5–3.0 gallon tank, it tucks neatly under a sink and pairs with standard 1/2 FIP hoses for flexible installation. The result is ready hot water close to the faucet, without long waits or excessive heat loss.

Fast heat, reliable performance

The 1500W L-shaped heating element increases the contact area with water, delivering heat more quickly. In practice, you can expect hot water in roughly 8–15 minutes for up to two sinks, depending on usage and incoming water temperature. A built-in smart chip tracks the target temperature and automatically insulates when reached to retain heat.

• 0.04 inch (1.1 mm) thick 304 stainless steel with laser welding resists rust, high pressure, and leaks
• Rapid heat transfer and automatic insulation help maintain steady hot water supply

Smart energy-saving design

Two compact configurations offer different capacities and max temperatures to fit your workflow. The 2.5-gallon model reaches up to 149°F with 99% thermal efficiency, while the 3.0-gallon version reaches 167°F at up to 98% efficiency. A digital display shows the current temperature and settings, and automatic insulation preserves hot water between uses.

• Smart chip automatically heats to the set temperature and then locks in heat
• Built-in insulation minimizes heat loss and helps reduce mineral buildup over time

Designed for versatile spaces

Wherever hot water is scarce, Agust provides a practical solution: kitchens, bars, under-sink setups, hair salons, RVs, and trailers. The compact form and simple connections make it a convenient point-of-use option.
