CONS

  • Relatively small capacity

Why it Stands Out to Us

This water heater features a small compact design that’s suitable for installing in locations with limited space. The electrical and plumbing connections located in its side have given it an advantage of adjusting into crawl worthy spaces like under a cabinet, sink, or in attics. Easy to install and operate, it is perfect for point of use situations.

With a 6-gallon capacity, it manages to supply a sufficient amount of hot water to sustain a small household. It comes with a 5-year warranty for tank and component parts. Add that to the mix, and you have a great product that reaches the top as the best overall A.O. Smith Water Heater on our list. 

Bottom Line

In our opinion, the A.O. Smith EJC-6 is the best product created by its manufacturer. Its small and compact design facilitates its installation in cramped spaces. Being small with only a 6-gallon capacity, it cannot fulfill the demand of a large household. However, you can install multiple products to get the job done. It can also be installed as a backup to facilitate dishwashers or washing machines.

It certainly lacks in terms of Energy Star Certification, but it makes up for it by being compatible with amperage. All in all, it’s a highly recommended product from a great manufacturer. It is a purchase you will never regret.

It is very easy to install; you can even opt to do it yourself. It is also pretty basic to operate. Its compact and low design enables tight space installation in places that don’t offer much height. If you are tight on money and installation space, then this is the right product for you.

It features a compact design that makes for convenient installation in the smallest of spaces.

A.O. Smith actually started out making car frames, having invented a lightweight frame that he sold to many of the top automobile manufacturers at the time including Cadillac and Ford. His son carried on the family business and developed it into an engineering company that far surpassed its competition.

The son, Ray Smith, led a team of engineers that found a more advanced method of welding. That allowed them to make advancements in their manufacturing of steel products, opening the company to the oil refining industry. Over the years, the A.O. Smith product line evolved with the development of steel tanks lined with fused glass. First used for beer kegs and brewery tanks, this technology fast made its way to the residential water heater world.

Expanding into China, the company has grown its research and development. The cutting-edge technological innovation gave to it the reputation it has today. Now it is one of the largest water heater manufacturers in the entire world. A.O. Smith delivers products with a focus on integrity, customer service, and dynamic innovation.

Tips to Reducing Water Heater Costs

Water heaters can be quite expensive to replace. In this sense, you’re looking to ensure you get the best deal. This not only includes the upfront price, but also the running costs of having it installed.

One of the main things is fuel consumption. No matter whether you’re choosing gas, propane or electricity, you want to consider the amount of energy it uses. Models that have the Energy Star, though more expensive up front, can reduce the cost of your hot water usage considerably. Think about choosing a high-efficiency model as it uses less fuel to produce high amounts of hot water.

Equally consider how you use your hot water. Installing an energy-efficient shower head and aerators on the taps will mean that you use less water at any one time. This prevents you from needing to heat so much.

Second, think of the rhyme, ‘if it’s not dirty, wash at thirty.’ Washing at 30C is usually enough to deal with clothes that aren’t very dirty. It also significantly reduces the amount of hot water you need to pump into your washing machine.

Think about where your water heater loses heat on its journey. Try insulating any bare pipes so that the heat isn’t lost on its way to the sink or shower. Insulate your tank well as this is a huge source of heat loss. Moreover, consider using a tankless or point-of-use water heater, to reduce the heat loss even more as the water doesn’t sit cooling down and wasting money.
