American electric model reviews

The American Company offers a wide selection of electric models with a variety of sizes; from 2.5-gallon Tiny Titan model to 119-gallon Standard tank type, including ultra-efficient heat pumps.

High efficiency

American electric water heater

There are four models of the American electric water heaters that are built for the high-efficiency water heating. They cover popular sizes of 40 and 50 gallons for the family of four to five, but also include larger sizes such as 66-gal and 80-gal, for the larger homes. Due to the 3-inch thick foam insulation and built-in heat traps, energy efficiency can reach high 95% for additional savings. All models are designed with the diffuser dip tube so self-cleaning reduces the sediment built-up.

The metal tank is protected from the aggressive water condition and corrosion by using the heavy-duty anode rod and fused strong ceramic shield. All these quality elements allow longer heater life so the manufacturer can provide a long 10-year warranty.


Lowboy water heaters are found in four sizes; 19, 30, 40 and 50 gallons, designed for heating potable water in homes that lack in space.

Lowboy models are short in size with an average height of 31" or 790 mm, giving them a great advantage over high-end models when installation requires small and confined space.


Standard series is the most versatile group, designed to meet a demand for hot water from smaller to larger homes and family sizes.

All the models are standard in height (tall); 30-gallon tank size is the smallest unit you can buy while the 119-gallon tank is the largest. Limited warranty is available for all units and the American heating company offers 6, 9 and 12 years.

Manufactured homes

If you own a mobile home or live in manufactured housing, you can select one of the three models; 28, 30 or 40 gallons’ tank size.


Utility heaters are for point of use application, for remote sinks or baths and for low hot water needs. There are 3 available models with 6, 12 and 20-gallon capacity.

American Water Heater Company also produces models for special applications. If you have a solar heating system you can combine it with 80 and 119 gallons solar-electrical water tank using factory installed solar circulation connections.

Tiny Titan

For the remote sinks, garage or offices, 2.5 gallons Tiny Titan, as the smallest unit, can ideally meet your needs for hot water. 

On the other hand, if there is no designated room for any of the freestanding units, one of the options is to use a tabletop electric water heater in your kitchen, and take the advantage of the extra countertop space.

Heat pumps

American heat pumps utilize an advanced hybrid technology that is as twice as efficient as the standard electric water heaters. These are the Energy Star appliances that offer great savings and many benefits to its owners.

How to choose the right electric-type size

When searching for the right electric water heater from the American company, keep in mind the next: if your family size is from 3-4 with a regular to low demand, the most used tank size is 50-gallon capacity. If your family is consisted of over five family members, you should consider models from 80 to 120 gallons to meet high demanding applications.

The above recommendation is calculated with the assumption that a person needs 3 gallons per minute for the shower. Another factor you should consider is the recovery rate; higher better.
