While all 50-gallon water heaters hold 50 gallons of water, they are not the same size. A few factors can affect the dimensions of a 50-gallon water heater.

One factor that affects the dimensions of a 50-gallon water heater is the thickness of the water heater's insulation. Inside a water heater, there is a tank made of glass where heated water is stored for use. Over time the hot water can cool significantly.

The glass tank is insulated with several inches of insulation to keep the heat from escaping. Different brands use different materials and thicknesses for their insulation, contributing to the differences in dimensions.

Another thing that affects the dimensions of a 50-gallon water heater is its height to diameter ratio. Water heaters with different heights will require different diameters to have the same amount of water in them.

While some companies prefer tall and slender water heaters, other brands opt for slightly shorter and wider water heaters.

As you can see, the dimensions of a 50-gallon water heater fluctuate depending on the brand. The main tradeoff for water heater dimensions is whether you want a tall and narrow water heater or one that is short and wide.

What Size Water Heater Do I Need?

You will want a water heater that is large enough that there is always enough hot water for your needs, but it shouldn't be so large that most of the hot water is never used. The first thing you need to calculate is how much hot water you use in a day.

The average American uses 17.2 gallons of water when they shower, and people also use around 20 gallons of water when washing dishes by hand. It also takes a 50-gallon water heater a little more than an hour to reheat.

Since some of the water used isn't hot water but comes from the tap, you will need to calculate this too. When you take hot and cold water into account, people use around half as much hot water per minute as total water per minute. You should have at least 10 gallons of hot water per person plus 10 gallons.

So if you need to know what size water heater you need, take the number of people who will use it and multiply it by ten, and then add 10 to get your answer.

So one person needs a 20-gallon water heater, and a family of 4 requires a 50-gallon water heater.

What Temperature Should A 50-Gallon Water Heater Be Set At?

A 50-gallon water heater should be set between 130 and 140 degrees Farheiniet. If the water is either too hot or too cold it can be dangerous.

You want to ensure your water heater is set lower than 140 degrees Farheiniet because the water can burn people. The highest temperature that is considered safe for water is 120 degrees.

When water flows from your water heater to your faucet, it cools. Water heaters should be set at a temperature that ensures the water never exceeds 120 degrees at the tap. If the water is hotter than 140 degrees Farheiniet in the water heater, it will be above 120 degrees Farheiniet at the faucet.

The hazard with the water in your water heater being under 130 degrees Farheiniet is bacteria. Bacteria can build up in your water heater if it isn't a sufficient temperature, which can potentially make you and your family sick.

Not only can the bacteria make you sick, but infections like staph can also quickly damage large amounts of tissue leading to debilitating skin conditions.

For your safety, a water heater should be set between 130 and 140 degrees Farheiniet.

How Long Can You Shower With A 50-Gallon Water Heater?

To find how long you can shower with a 50-gallon water heater, you will have to know how fast your shower head's flow is. Your shower head's flow can vary, but two gallons per minute is a good average.

The other factor that will affect how long you can shower is your hot to cold ratio. If you use a 1 to 1 ratio of hot and cold water, you will use one gallon of hot water per minute, and your shower will last for 50 minutes.

If you have a 55% to 45% hot water to cold water ratio, your shower will only last 47.5 minutes, and if you opt for a 45% to 55% hot water to cold water ratio, your shower will last 52.5 minutes.

As you can see, your shower head's flow rate and your hot to cold water ratio will affect how long you can shower with a 50-gallon water heater.
