American electric water heater

The American Company offers a wide selection of electric water heaters with a variety of sizes and capacities. All the electric models are coming from the ProLine group, which has the largest selection, also from ProLine Master and XE group, which is the most advanced.

While most of the electric water heaters have the high energy factor, none of the conventional types is Energy Star compliant, while the hybrids or heat pumps are.

If looking for electric water heaters for one fixture such as the distant sink or office, choose a point-of-use model, such as the Tiny Titan model with 2.5-gallon capacity and install it under or above the sink. If you need more hot water, but still for lower demand, choose one from the Compact series, which has models up to 20 gallons, still for point-of-use applications.

If you need hot water for one or two fixtures including shower, and if you live in an apartment, small house or need one for a cottage, get the Lowboy model, they are available in sizes from 20 to 50 gallons but are short, so they can fit in homes that lack in space.

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.

If you need a unit which will perfectly fit in your kitchen layout, buy the Table Top model – a model that will also provide an extra countertop space. For those who need hot water in the manufactured homes and RVs, you can get one of the three available models for that purpose.

American heat pumps are for homeowners how are looking for the cutting-edge technology and electric devices that will bring the greatest savings possible. This type utilizes an advanced hybrid technology that is twice as efficient as the standard electric water heaters and has the high recovery rate and First Hour Delivery, making them ideal for large homes and families looking for savings. Check them out here.

The standard type of Proline series is the most versatile and extensive group, designed to meet the 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 119-gallon tank is the largest. Read the review about Standard series.

Most of the electric water heaters come with the industry standard warranty of 6 years, while better ones offer 8-and 10-year of protection.

In order to buy the best, look for the high efficient models (such as models from XE series), models with the self-cleaning feature which reduces the risk of sediment build-up, commercial grade anode rod, or powered anode, for great protection against corrosion, and built-in electronics for easier diagnostics.

How to choose the right electric-type size

When searching for the right electric water heater from the American company, keep in mind 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 the high demand or models with the higher recovery rate. For the low demand homes, use the point-of-use or Lowboy models.

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.
