How Often Does a Water Heater Need to be Replaced?

When is it time to replace your water heater?

For the most part, when you replace your water heater depends on its type, size and age. On average, most water heaters last about 10 years. Electric water heaters will typically last a little longer than gas water heaters. Good maintenance, such as regular flushing, will help your water heater last longer.

If you have a tankless water heater, you can expect it to last about 15-20 years. Again, regular maintenance will ensure its longevity.

Water heater replacement is recommended if you’re spending more on repairs than you would buying and installing a new unit.

Can I install a water heater myself?

While it’s not impossible for you to install a new water heater yourself, it’s not recommended, especially if you have no plumbing or electrical training. Not having any training can put you, your family and your home at risk of injury or damage.

Moreover, you’ll need to get the water heater to your home, you’ll need all the right tools and additional supplies, and you’ll need to get a permit from the city. You will also have to get the city to come out and inspect it after it’s installed.

When it comes to water heater replacement, plumbing professionals are your best choice. They’ll have all the right skills and equipment to install the water heater and they’ll be able to get the necessary permitting and inspections from your city. All you’ll have to do is enjoy the hot water.

What are the signs that your water heater needs to be replaced?

If you think it might be time to replace your water heater, here are 6 ways to tell it’s time to replace your water heater:

• Water pools around its base: If water is standing around the base of the water heater, you probably have a leak. Water heater replacement will preserve your home from water damage.
• Rusty water appears in the sink: If your water appears rusty or there are rust stains around your sink, this is usually a sign that your water heater is rusty as well. When you replace rusty water heaters, you’ll improve the water quality and prevent leaks.
• Metallic smell or taste to water: Metallic odors or tastes usually indicate that the water heater’s metal tank has begun to corrode.
• Cold water that won’t heat: If you get hot water one day but can’t the next, your water heater–probably the heating element–is worn out and it’s time for a new one.
• Age: Any water heater that’s 10-15 years old is probably beginning to show signs of wear, even if you’ve kept it maintained. Professionals can test it to see if you need a new one.
• Constant repairs: If you’re constantly having to repair your water heater, you’re usually better off getting a new unit. You’ll save money in the long run.

Water heater replacement, gas or electric?

When choosing between installing a gas or electric water heater, the main thing to consider are your needs and budget. Both have advantages and disadvantages, although electric water heaters tend to be a little cheaper to install and often last longer than gas water heaters.

Gas water heaters also tend to use more energy than electric units. But, if you have gas lines already installed in your home, then installation costs might not be as high.

Again, you’ll have to weigh your options based on what you need for your home, as well as your budget.

Water heater repair vs. replacement

Several variables come into play when choosing to repair or replace your water heater. One big factor is age. The older your water heater is, the more likely it will be worn. You’ll tend to see problems like rust or corrosion or leaks that make it hard to repair.

No matter how old your water heater is, if you’re constantly calling your plumber out to repair it, you’ll be better off getting a new water heater. You’ll end up spending less money in the long run.

Is a tankless water heater better?

Tankless water heaters have their advantages and disadvantages. Of course, the biggest advantage of installing a tankless water heater is that you get hot water on demand. You won’t have to wait for the water to heat up before you shower or wash dishes.

But, initial installation can be expensive. And you may need more than one tankless water heater in your home, depending on the size of the home and the size of the unit you install. These costs, though, are often offset because tankless water heaters have fewer problems than standard water heaters, so you’ll save on maintenance costs. They also tend to last longer–about 15-20 years–than standard models.
