Hot water is probably the greatest invention since the discovery of fire, and we couldn’t imagine our lives without it a now. However, plenty of houses still use large boilers to heat the water instead of other types of tankless boilers that provide constant hot water. And, although the main inconvenience is that you will have to wait until the boiler fills back in with water, these items remain the most affordable ones. So, if you’re looking for a large water heater, we think that the A.O. Smith ENS-50 ProMax is the perfect choice because the 50-gallon water tank is large enough for a family with up to three members, it is made of permaglas to protect the steel tank from corrosion, and meets all current regulations of NAECA. Should the A.O. Smith ENS-50 not be available for purchase, you could also consider the A.O. Smith XCG-50 as a great alternative.



Buying guide


Choosing the best 50-gallon water heater could prove a challenge, especially since there are so many good products available for sale for a good price. Thus, the first thing you should do is start by reading some online reviews of 50-gallon water heaters and see what others have to say about a certain product.

If you’re still not convinced, our comprehensive shopping guide aims to deliver the most important information and the most relevant features you need to take into account to make sure you purchase the best water heater on the market.


Size of the water tank

Since we are mainly discussing 50-gallon water heaters, we will assume all the items you are looking for provide this water capacity. However, the size is extremely important and should be chosen accordingly to the number of family members or the number of people sharing the same household.

Keep in mind that a 50-gallon water heater will suffice for a family with up to three members. In fact, 50 gallons are the equivalent of approximately two showers, two food preparations, and two shaves, all without consuming the entire capacity of the water tank.



Most of the water tanks are powered by electricity or gas, although there is also the alternative of solar panels and heating pumps. Each of them comes with its own benefits and downsides, so it is mainly up to you to discover the best option that suits your household.

Electricity boilers are the most common type and mainly use one or two replaceable heating elements to deliver hot water. They are usually the most price-convenient, and their mounting is fast and easy. Also, you can choose between a wide variety of energy-efficient models that will save you big money on your monthly electricity bills.

Gas-fueled water heaters use a burner to heat the water and are mainly more expensive than the electric ones. However, they are more energy-efficient since gas is cheaper than electricity in most of the countries.

On the other hand, they are also heavier, and you should under no circumstances store combustible materials near it. Also, their installation requires professional help and a number of previous permits.

The solar energy boilers use the sun as a primary resource for producing heat. These are usually quite expensive at the beginning, but if you live in a sunny area, you will be getting heat and hot water inside your house for free most of the year. Sure, we don’t suggest opting for these products during the winter or in colder areas where the sun is rather shy during some of the months.


Other features to consider

Anti-scale devices, as well as anti-rusting features, are probably the most important aspects you should take into account besides the ones above. Needless to say, a device that builds-up scale or rust will work less efficient and is prone to breaking anytime soon. So, if you want to protect your initial investment, you need to invest in some of these vital features.

Warranty is also essential, especially during the first years of your product’s lifespan. A good 50-gallon water heater should work perfectly at least five years, but if anything goes wrong, the initial warranty will have to cover the fixing costs or the replacement of your item.
