To help you determine which is the best 50 gallon gas water heater for you, we have also prepared you a buying guide. This way, you will have the knowledge you need not to make a mistake when trying to find the best product.

Why Choose the Best 50 Gallon Gas Water Heater?

50 gallon gas water heaters are the most popular heating products currently on the market. This is because of the many advantages they have compared to other models.

First off, gas water heaters will make your water hot in no time. They are amongst the fastest products you can find. This way, you can save your time while also having warm water you can use for any activity. You can have hot showers and baths whenever you’d like, and you don’t have to worry about cold water while doing dishes.

Also, gas heaters are energy-efficient, especially compared to electric ones. They consume less power than regular heaters and are even more affordable. At the same time, they require less energy to provide an equal amount of hot water.

Last but not least, gas water heaters can work during a blackout. If you live in a neighborhood where the electricity goes out all the time, a gas heater might save you a lot of stress.

What Features to Look for in the Best 50 Gallon Gas Water Heater?

Choosing the best 50 gallon gas water heater seems like a piece of cake. However, it really isn’t as easy as it looks. You need to know what makes the right water heater before making that purchase. Below are some crucial features that you should consider before spending any money on a product.

Storage Tank

The most important thing you should look for in a heater is whether it has a storage tank. It’s always better to choose a heater with a tank, as it serves to store all that hot water you’ll need. Tankless heaters will require you to wait before using the water, while water in tanks will be pre-prepared. If you choose a gas heater with 50 gallon tank, you will have enough water supplies for a significant time.

First-hour Rating

The first-hour rating of a gas heater is critical. A good 50 gallon tank should deliver around 70 to 80 gallons of warm water just during its first hour. Any less than that and the heater will have a bad rating.

Energy Efficiency

Gas water heaters are energy efficient on their own. However, how much power they’ll save depends on their tank. The more water the tank can store, the more electricity you’ll save. This will also mean lower utility bills, which is always the right choice.


The display isn’t a necessity, but it helps a lot. Choosing a gas water heater with a digital display can make everything much easier for you. This way, you will be able to see the water flow and the temperature quickly. Also, LCD screens can help you adjust everything exactly as you’d like.


When you pay an exceptional amount of money for a product, you’d expect it to last for a long time. Heaters manufactured with high-quality materials will usually last longer and are thus considered to have a higher value. Also, it’s always a good idea for your heater to have replaceable parts, so if something does break, you can simply change that one part. This is much more affordable than having to buy a new heater.

Installation and Maintenance

All gas water heaters should be installed by a professional. However, some require more maintenance than others. We live in a busy world, and most of us just don’t have the time or money to spend on product maintenance regularly. Always choose the product that requires as little maintenance as possible.


Price shouldn’t be the most critical feature, but it sure can change your final decision. It would be best if you always tried to find the best 50 gallon gas water heater for the price. Not every expensive product is necessarily the right product, just like an affordable product isn’t always bad. Choose wisely!
