Both brands offer a wide range of water heaters, including tankless water heaters, electric water heaters, and gas water heaters, catering to diverse needs.

While AO Smith is known for its innovative heating solutions, Rheem has built a reputation for durability and energy efficiency.

These brands not only dominate the residential water heaters market but also offer robust solutions for commercial water heaters.

AO Smith Water Heaters

AO Smith is a go-to name for high-quality water heaters. They offer various types of water heaters, including conventional tank water heaters, tankless water heaters, hybrid water heaters, and solar water heaters.

Their electric tankless water heaters are particularly popular for their energy efficiency and compact size, providing endless hot water on demand.

AO Smith also excels in offering storage tank water heaters with advanced features like glass linings and anti-scale devices, ensuring longevity and consistent performance.

The brand’s commitment to innovation is evident in its heat pump water heaters and solar water heater options, which utilize renewable energy sources for greater energy efficiency.

Rheem is another top contender in the water heater market, known for its wide range of energy-efficient water heating solutions.

From traditional gas water heaters to advanced condensing water heaters, Rheem has something for every household. Their tankless units are renowned for providing hot water efficiently without the need for a large storage tank.

Rheem’s electric water heaters, including their hybrid water heater models, are designed for high energy efficiency, often incorporating a heat pump system to maximize energy savings.

Rheem is ahead in the game when it comes to incorporating smart technologies, with features like digital displays and remote control options, enhancing the user experience.

Both AO Smith and Rheem have mastered the art of water heating, offering a variety of solutions from storage tank water heaters to high-efficiency tankless models.

What are the Types of Water Heaters?

In the search for the best water heater brand, understanding the different types of water heaters is crucial. These types range from conventional storage tank models to innovative solar and heat pump designs, each with unique features and benefits.

Storage Tank

Storage tank water heaters are the most common type, found in many households.

They consist of an insulated tank where water is heated and stored until needed. These heaters typically use natural gas or electricity, with natural gas models being more energy efficient.

Storage tank water heaters are known for their reliability and simplicity but can consume more energy due to constant heating.


Condensing water heaters are an energy-efficient option for homes that use natural gas.

These units capture exhaust gases that would otherwise escape out the flue and use this energy to heat water.

They are particularly efficient when heating a large amount of water and are an excellent choice for homes with high hot water needs.


Tankless water heaters, also known as on-demand water heaters, heat water directly without the use of a storage tank.

When a hot water tap is turned on, cold water travels through a pipe into the unit, where it is heated by either a gas burner or an electric element.

These units are more energy efficient than traditional storage tank models, as they only heat water when it is needed, offering endless hot water and saving energy.

Heat Pump

Heat pump water heaters move heat from one place to another instead of generating heat directly for providing hot water.

These heaters use electricity to move heat from the air or ground to heat the water. They can be two to three times more energy efficient than conventional electric resistance water heaters.

By using the heat pump technology, they reduce electricity use significantly.


Solar water heaters use the sun’s heat to provide hot water. They are comprised of solar collectors and a storage tank.

These are an excellent option for high energy efficiency, especially in sunny regions.

Solar heaters can be more expensive initially but can significantly reduce energy bills, making them a cost-effective solution over time.

How to Choose The Best Water Heater

Selecting the best water heater brand requires understanding various factors that impact the heater’s performance, energy usage, and suitability for your home. Here’s a breakdown of key considerations:


The capacity of a water heater is a critical factor, especially for storage tank models. It’s essential to choose a size that can meet your household’s hot water needs.

For tank water heaters, capacity is measured in gallons. Larger families typically need bigger tanks, but be mindful of space constraints.

In tankless water heaters, capacity is less of a concern since they provide hot water on demand.

Energy Use

Energy efficiency is a major consideration when selecting a water heater. Look for models with high energy efficiency ratings to save on utility bills and reduce environmental impact.

Options like heat pump water heaters, solar water heaters, and high-efficiency tankless units are great for achieving better energy efficiency.

Natural gas water heaters generally offer higher efficiency compared to electric ones.

First Hour Rate

The First Hour Rate (FHR) is crucial for storage tank water heaters.

It measures how much hot water the unit can supply per hour, starting with a full tank. A higher FHR means the heater can deliver more hot water during busy times.

Consider your peak hour demand and choose a unit that meets or exceeds that requirement.

Gallons Per Minute or Flow Rate

For tankless water heaters, the flow rate, measured in Gallons Per Minute (GPM), is an essential factor. It determines how much hot water the unit can provide at any given time.

A higher GPM is necessary for larger households or if multiple hot water sources are used simultaneously.

Be sure to assess your typical hot water usage to find a tankless model that can handle your needs.


The warranty offered with the water heater is a reflection of its quality and durability.

Longer warranties typically indicate a more reliable and robust product. Consider the length and comprehensiveness of the warranty, including what parts are covered.

Some of the best water heater brands offer extensive warranties, which can be a sign of their confidence in the product’s performance and longevity.
