As it turns out, water heaters really can last decades. Larry Weingarten, one of the most knowledgeable hot water experts in the world, wrote this in his new book*: “The average life of tank-type water heaters is nine to twelve years, but with periodic maintenance I've gotten fifty years from them!”
Signs Your Water Heater Is Nearing the End of Its Lifespan
Most heaters have a lifespan of 8-20 years.
That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality. If your water heater is more than 10 years old, leaks around the base of the tank or operates erratically, it's probably time to replace your water heater.
Tankless water heaters have the longest life expectancy of all three types, at more than 20 years.
Common signs that it's time to replace your water heater include its age (usually 10-15 years), rusty or discolored water, strange noises, leaks or pooling water around the tank, and insufficient hot water supply.
Water heaters show several signs of going bad, including lack of hot water, temperature fluctuations, decreased water pressure, strange noises, rotten egg smell, visible leaks, rusty or discolored water, and increased energy bills. If your water heater is over 10 years old, it may be time to consider a replacement.
Once you decide to (or are forced to) replace your current water heater, there are a few decisions you need to make to get the process started. If there are no issues or complications, a licensed plumber should be able to complete the process in 2-3 hours.
Sometimes, you'll just need repairs, but serious issues call for replacement. For example, a 30-year-old water heater certainly needs to be replaced, but a younger one with a minor problem may be able to get by with some simple repairs.

Rheem hot water systems have a typical life span of between 5 and 15 years depending on water conditions and how well the system has been serviced. You can add years to the life to a Rheem hot water system if you have it serviced every 5 years.
Age of the Water Heater: Insurance companies may reduce coverage for water heaters beyond a certain age, typically around 12-20 years. Older water heaters are more prone to leaks, corrosion, and other issues, increasing the risk of damage.
Most homeowners should flush their water heaters every 6 months or so, but if you have extremely hard water, you may want to do it more often. Flushing your hot water heater could be necessary as often as every few months depending on the mineral content of your local water supply.
Chemicals and minerals in our water can contribute to the corrosion and breaking down of the inside of the tank. The sediment and particulates can then build up and reduce the available water to be heated and used by your home.
A Corroded Water Heater Could Cause Significant Damage
If the tank rusts through, it could fail catastrophically and flood your home. You can avoid this disaster by replacing your water heater before it fails.
If your tank water heater is more than 10 years old, it may be time to consider replacing it. With proper maintenance, a tank water heater tank should last six to 12 years. A tankless water heater can last for more than 20 years. Check your water heater's warranty for the most accurate timelines.
This is because the process of installing a new water heater can be quite complex and often requires the use of special tools and equipment. Additionally, the cost of labor for this type of project can be quite high.

Naturally, tanks that heat more gallons of water typically have a higher price point, so the larger the tank size, the more you can expect to pay. For example, the average 40-gallon water heater installation cost runs between $1,000 and $2,500, while its 80-gallon counterpart runs between $2,650 and $3,910.
Sediment can build up over time in a water heater, shortening its lifespan. To prevent this, you should flush your water heater at least once per year. Flushing will help to remove any sediment that has built up and improve the efficiency of your water heater.

Water Heater Quality
The units available at a retail store or online typically are not the same as those sold through a local plumber. Low retail prices are often possible due to lower product quality and the use of less durable components.
The price depends on whether you want an electric or gas water heater. The basic installation fee at Lowe's is around $320. But, before the contractor can set up the heater, they'll need to come to your home to check the conditions and determine the best location for it. This inspection will cost you an additional $34.
