Key specs for this mini tank
Capacity: 2.5 gal.
This unit holds a small volume of heated water. You get a short burst of hot water for quick tasks. It is not for whole-house needs. Compare this to tankless models that heat water on demand. This mini tank is best for single sinks or small bathrooms where flow volume matters less than instant availability.
Voltage: 120
The heater runs on a standard household outlet. You do not need special wiring or a high-amperage circuit. This makes installation easier than for larger units. When shopping for tankless heaters, note that many require 240-volt lines. This 120-volt spec means you can plug it into a regular wall socket in most homes.
Wattage: 1440 Total Watts
This power rating determines how fast the water heats. At 1440 watts, the heating speed is modest. It suits low-flow fixtures like bathroom sinks. Higher wattage units heat water faster. Compare this to tankless heaters with higher input ratings. This spec tells you the unit is best for gentle, steady hot water rather than high-volume showers.
Installation Location: Point-of-Use
This unit is designed to sit close to the faucet it serves. It reduces the wait time for hot water by minimizing pipe distance. Tankless heaters can be installed anywhere, but this mini tank is compact for tight spots. You should place it under a sink or in a small cabinet near the usage point for best efficiency.
Design and build specs
According to the listing, this unit is a compact point-of-use water heater. The model number is EMT2.5. It features a white finish on the exterior casing. This color choice helps it blend into most utility areas or under-sink cabinets without drawing attention. The design prioritizes space efficiency over large storage volume.
The physical dimensions are 17 inches in height, 11 inches in width, and 11 inches in length. This small footprint allows you to mount it in tight spaces where a traditional tank would not fit. You can place it directly near the faucet it serves. This reduces the distance hot water must travel through pipes. The compact size also means it takes up minimal floor or shelf space.
The unit is built for both commercial and residential use. This dual rating suggests a durable construction suitable for higher traffic environments. It runs on a standard 120-volt circuit with 1440 total watts. This power level is standard for under-sink installations. You do not need special high-voltage wiring. The simple design focuses on delivering hot water quickly to a single sink or small area. There are no complex digital controls mentioned. The build is straightforward and functional for its specific point-of-use role.

You must verify local plumbing codes for point-of-use installations. The compact size fits under sinks, but measure your space against the 17 by 11 by 11-inch dimensions.
