american water heater lg

Do you have a water heater in your home, and have you ever used an American water heater? Across the states of America, American Water Heaters have proven their efficiency and durability for households.

American water heaters are among the best brands on the market, including Proline, Polaris, and Standard series. The company responsible for manufacturing these heaters offers an extensive line of commercial and residential models. The good thing about American water heaters is that they are designed for various homeowners, home types, and applications. These include ultra-high condensing, green technology, budget-friendly, and energy-efficient models. 

In this review, we look at the American Water Heaters and what they involve. 

Are American Water Heaters Good?

American Water Heaters are long-lasting and reliable water heaters. They are also energy-efficient and experience high performance. 

You can either select either the condensing or non-condensing model. They offer plenty of water with reduced gas emissions and energy waste. 

We recommend that you go for these heaters if you are looking for both efficiency and reliability in performance. 

How Long Does An American Water Heater Last?

The American water heater will last for between 8 to 12 years, according to the manufacturer. However, the exact period varies depending on the quality of installation, water quality, maintenance schedule, and unit design. 

Even though the American water heaters today are better designed compared to older models, they still need regular repair and maintenance to prolong their lives. 

In most cases, an electric water heater lasts more than a gas water heater. 

Who Makes the American Standard Water Heater?

American Water Heaters makes and distributes commercial and residential American Standard water Heaters. The company has its headquarters in Johnson City, Tennessee. 

The American Water Heaters is a subsidiary of the A.O. Smith Corporation. The company offers both tankless and highly efficient tank models, most of them being awarded Energy Star. 

The company produces different models, including electric and gas models, as we’ll see below. They are also ideal for earth-friendly installations and are LEED recognized. 

American Electric Models

The company produces a variety of quality electric heaters with different capacities and sizes. All the electric models under this category come from the XE group, ProLine Master, and ProLine group. 

Even though the electric water heater comes with a high energy factor, none of the conventional heaters is Energy Star compliant. However, the heat pumps or hybrids are Energy Star compliant. 

If you want an electric heater for a single fixture such as an office or distant sink, select a point-of-use model. This might include the Tiny Titan model, which has a capacity of 2.5-gallon. You can install it either above or under the sink. 

If you require more hot water, select a compact series model. This type of electric water heater has models with a capacity of about 20 gallons. They are developed for point-of-use applications. 

If you require hot water for at least two fixtures, get a lowboy model. They can fit in homes with limited space and are available in capacities of 20 to 50 gallons. 

The American water heater company produces electric heater models for specific applications. 

American heat pumps are available for homeowners seeking cutting-edge technologies and electronic devices to offer the highest savings. 

For you to purchase the best model, go for high efficient models, commercial-grade anode rods, models that have self-cleaning features, built-in electronics for quicker diagnostics, and powered anode for better protection against corrosion. 

The American Gas Model

These models also come from the ProLine XE, Proline master, and ProLine series. They are also protected with a 10, 8, and 6-year warranty. 

The models are only available in short and tall models with capacities of 30 to above 75 gallons.

Even though they’re mainly built for small commercial and residential applications, some models can be employed in mobile homes. 

Recommended models have user-friendly features, powered anode, a self-powered gas valve with a diagnostic system, Energy Star approved, and an intelligent control logic system. 

Tankless Models

If you would like to have a device that heats water on demand, the best option for you is tankless technology. 

American tankless water heaters are reliable, long-lasting, and small units providing better energy efficiency and high performance. 

As we have seen before, you can either choose the condensing or non-condensing model. The models offer a reduced wastage of energy and plenty of water.

With innovative features and built-in quality materials and elements, the company offers a 15-year warranty. Most of the components on the heater are replaceable. 

The maximum flow in these water heaters is 10 GPM.

What Warranty Does American Water Heater Offer?

Every water heater user would like to buy a new heater that has a warranty. A warranty gives you a unique chance to ask for a replacement if an unplanned fault occurs within the warranty period. 

The company offers warranties on almost all products that vary from one product to another. A warranty is available for the tank and its parts. Most PG10 water tank models come with a warranty of 10-years for the tank. The PVG water heater has a 6-year limited warranty, while the GT line model comes with a 25-year limited warranty. 

For the parts, all models have warranties of 1-year. However, the PVG heater parts come with a warranty of 6-years. 

The warranty isn’t transferable, and if you use the product in a commercial setting, it’ll reduce to 1 year only. The warranty will apply if you follow the installation guidelines effectively. 

If your tank parts, except for the anode, are damaged or the inner tank leaks within the warranty period, you’ll get a new replacement. 

However, no warranty will apply if the heater or the parts are misused, unapproved arts & aftermarket have been added, its application isn’t according to the guidelines, and it isn’t installed properly. You can check out the American water heater site for more information. 

To claim the warranty, you should be the original buyer and provide the serial number, model number, location, date of installation & purchase, and product number. 

What Are The Things To Consider When Buying An American Water Heater

Before you purchase an American water heater, there are various factors that you should consider: 

Source Of Energy

Here you should consider whether you should use natural gas, propane, solar, or electricity. The cost will be high if you choose propane over natural gas since propane is more expensive. 

In most cases, people use natural gas and electricity. However, natural gas is the least expensive of the two. 

You should remember that almost all homes are connected to electricity and not natural gas. The use of electricity is also a viable option and cost-effective. 

However, remember that the more power, the more hot water you’ll have in your home. 

Location of Your Heater

As per the NAECA 3 (National Appliance Energy Conservation Act) requirements, it isn’t possible to install the same sized new heater in the place of the existing unit. If it isn’t possible to replace your current tank, you can go for a tankless option. 

However, you should know the tankless unit’s power requirements since most tanks have a 30 amp wire size and breaker.

It will help if your water heater is near the point of use. You should place the heater in a more centralized location. 

The Starting Groundwater Temperature

With most tankless heaters, you’ll need a properly sized home. You should calculate the power required to provide your desired temperature. The groundwater temperature is critical since it’s the starting point. 

For instance, if you reside in a colder climate, you’ll need more power to heat water to about 104° F. In such a case, you should go for an energy-efficient American water heater.

The Amount Of Hot Water You Need

If you need a lot of hot water at a time, you should look for water heater products with a low flow rate. There are states, including California, that have laws to govern the application of low-flow and high-flow fixtures. 

If you are unsure of the water heater to use, you should consult a professional plumber to help you out. 


American water heaters constitute some of the most reliable water heaters in the industry. These heaters are available for both commercial and residential purposes. 

You can find a water heater for any application or home type. The American water heaters are also energy-efficient and budget-friendly. 

If you’re unsure of which product to buy, you should consult a professional plumber.
