American Water 100290576 40 Gal 4500W Electric Water Heater

Product Description

The AMERICAN WATER 100290576 is a 40-gallon tall electric water heater designed for residential and light commercial hot water supply systems. Rated at 4500 watts and 240 volts single-phase, it delivers reliable domestic hot water capacity for standard household demand. The unit stands 61.25 inches tall with an 18-inch diameter footprint, making it suitable for utility closets, basements, and mechanical rooms where a tall-format tank fits the available space. This water heater is installed by licensed plumbers as part of a new installation or direct replacement of an existing electric tank-style unit.

This 40-gallon tall electric water heater is suited for residential applications requiring consistent hot water volume. The tall configuration allows a larger tank capacity within a compact floor footprint compared to short or medium formats. It operates on a standard 240-volt single-phase circuit, which is the most common electrical configuration for residential electric water heaters. Plumbers and mechanical contractors select this format when replacing aging electric tank units or roughing in new construction plumbing systems.
