A hot water heater is an essential part of any household, but there are many factors that can shorten its lifespan. If your particular model isn’t designed to last as long as others or if you have a high water use, there are a few things you can do to extend the life of your water heater. A properly maintained water heater is crucial to maintaining a comfortable household temperature year-round. It’s also an important safety feature that is regulated by local building codes. When it comes to your water heater, it’s important to understand its pros and cons so you can make the best decision for your home and family. An inefficient water heater will cost you more in the long run because you’ll end up using more of your local water supply. It also might not get hot enough to meet your needs or be able to maintain a consistent temperature throughout the day and night as needed. A water heater that’s past its prime can be dangerous, so it’s important to know when it’s time to say goodbye and replace it with a new model.

Know the lifespan of a water heater

The average lifespan of a water heater is about 10 to 12 years. That’s if it’s properly maintained and if you have a water use that’s typical for your home, including the occasional trip to a spa or high-end kitchen. If you live in an area with a higher water use, such as a large family or a household with a lot of pets, the lifespan can be reduced. The best way to extend the lifespan of your water heater is by regularly maintaining it. That includes cleaning out the inside of the tank and checking the condition of the tank and the water line at the same time. If you notice anything that could be harmful to the water supply, it’s important to get it fixed as soon as possible.

Consider the type of fuel source for your water heater

There are two main types of fuel sources for hot water heaters: natural gas and electricity. Each has its own advantages and disadvantages. Natural gas is the most common source of fuel for hot water heaters, so it’s important to understand the pros and cons of each type. Natural gas is an abundant resource in most areas, making it a reliable and cost-effective fuel source. However, natural gas comes with a higher upfront cost and can be difficult to install. When you buy a natural gas water heater, you’ll also have to deal with additional regulations, which can be a hassle. Natural gas heaters can also be pricey to run, so if you use a lot of hot water at peak times or in a high-end kitchen, a natural gas water heater might not be a good fit.

Water softeners and water filters

If you have a hard water supply, it could be impacting the lifespan of your water heater. A water softener is a device that removes calcium and magnesium from your water to make it softer. A water softener can actually extend the lifespan of your water heater, so it’s important to know if you have a hard water supply. A water softener will help your water heater last longer, but you’ll need to install a new filter every 6 months to keep up with the water flow from the water softener. A water filter won’t extend the lifespan of your water heater, but it can help reduce the risk of contracting harmful bacteria and other contaminants from your water supply.

What’s the best age for a new water heater?

The best age to buy a new water heater is about five years before the current model’s expected lifespan. That will give you enough time to research and decide on the best water heater model to purchase, and you’ll also have time to save up for the installation and any necessary repairs. Keep in mind that the age of your water heater is just a general rule of thumb. It’s best to talk to your plumber to see what the best age is for your home and family. Your home’s water use, water quality, local water supply, and other factors will impact the ideal age of your water heater.

Summing up

A water heater is an essential appliance in any home, but it’s an appliance that can break down. It’s important to know the lifespan of a water heater, and you can extend the life of your water heater by checking the condition of the tank and water line at the same time. You should also consider the type of fuel source for your water heater and the age of the current model. It’s important to know the pros and cons of each option, so you can make the best decision for your home and family.

Frequently Asked Question

While you technically can install a hot water heater yourself as a homeowner, the likelihood that this is a good or safe idea is very slim. Trust the professionals with your hot water heater installation to make sure it's done correctly. You wouldn't want to cause yourself or your family any harm.
The higher cost is a result of a more labor-intensive set-up, as new gas and water lines are required for installation. For a new tankless water heater, new electric wiring will need to be installed.
Turn off all water supplies in the house. Turn on all the hot water faucets in the house in order to drain what is left in the existing hot water heater. Then, disconnect the water line that connects the water heater to the rest of the house. There is often a connection on a hose that you can simply unscrew.
  • Your older water heater is getting up there in age
  • It's making strange noises
  • You're getting rusty water out of the tap
  • Your hot water doesn't last as long as it used to
  • There are water puddles around the unit
120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire's disease.
Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank. (Not the thermostat on the wall.)
Sediment buildup shortens the life of your water heater and adds to your energy bill by reducing its efficiency. Draining two or three gallons of water is usually enough to flush out sediments, but always let the water flow until you no longer see particles in the bucket. Regular water heater maintenance will always extend its lifespan.
These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home. The national average cost to replace a 50-gallon water heater is $1,100 to $2,800, with most people paying around $1,800 for a direct replacement of a 50-gallon gas hot water heater using the same model.
  • You're overusing hot water.
  • The water heater tank size is too small for your household.
  • Your hot water heater is tankless.
  • Sediment or minerals have built up in your water heating system.
Soft water can actually corrode the water heater anode faster. When the anode wears down, the corrosive elements will move on to the tank. So if left alone, a water softener system can actually shorten the lifespan of a water heater.
