American Water 100309658 30 Gal Lowboy Electric Water Heater

Product Description

The AMERICAN WATER 100309658 is a 30-gallon lowboy electric water heater rated at 4500 watts and designed for 240-volt, single-phase residential service. The lowboy profile measures 24 inches in diameter by 31.25 inches in height, making it well suited for installations where vertical clearance is limited but floor space is available. A licensed plumber or qualified service technician installs this unit in residential settings. The 4500W heating element and 240-volt input deliver reliable hot water recovery in tight-space applications such as crawl spaces, utility closets, and low-ceiling mechanical rooms.

This unit is intended for residential plumbing systems where a compact, floor-standing electric water heater is required. The lowboy configuration is a common choice in homes with low basement ceilings or under-stair mechanical spaces. At 30 gallons, this heater fits small households or supplemental hot water applications. It operates on a standard single-phase 240-volt circuit, which is the typical residential electric service configuration for water heating equipment.

Installation Notes
