So, how long do hot water tanks last? Taking into consideration the above information, you can expect your hot water tank to last, on average, for about 7 to 15 years. However, if you go for a tank-less (or instant) hot water system, you can expect to add at least a few years onto that.
Tankless water heaters typically have a lifespan of 20 years or more. Traditional water heaters with standing water tanks can last around 10 to 15 years before you notice signs of age.
A hot water heater's lifespan depends on many factors, including the type of water heater, the energy source, the type of water you have, and how well the unit is maintained. On average, most water heaters last between 8 and 12 years but some can last up to 20 years with regular maintenance.
Gas Hot Water: 8-12 years. Electric Hot Water: 10-15 years. Solar Hot Water: 10 years.
Can a water heater last 30 years? It is unusual for used water heaters to last 30 years. Most tank water heaters have an average lifespan of 8 to 12 years, and tankless water heaters can last as long as 20 years.
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.
Water Heater Lifespan
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.
Over time, sediment can build up in the bottom of the tank and cause the unit to overheat. This can shorten the lifespan of the unit and lead to expensive repairs. To avoid this, it's important to flush the tank regularly. Most manufacturers recommend flushing the tank once a year.
It is recommended that you flush your water heater at least once per year. Doing so will help to prevent the potential problems that sediment can bring over time.
According to Angi and HomeAdvisor, the average water heater replacement cost can range from $810 to $1,656, with the national average around $1,217, depending on the type and size of the water heater. The different types of water heaters include standard tank storage, tankless, hybrid or high-efficiency, and solar.
According to Consumerreports.org, gas water heaters usually last 10 years and tankless water heaters last 20+ years. So, if your water heater is near the end of it's life, it would be wise to replace instead of repair--especially if the repair is costly.
Storage tank water heaters can cost around $500 to $800, but costs vary on the size of the tank. Installing a tank-style hot water heater averages between $650 and $2,100. Tankless water heaters have pros and cons and they have gained popularity as people strive to make their homes energy efficient.
Average Lifespan Of A Hot Water Heater
With regular inspection, draining, and flushing, you can expect a gas water heater to last anywhere from 8-12 years and an electric water heater to last anywhere from 10-15 years.
Over time, the sediment hardens and grows thicker along the tank floor. Sediment can wear a water heater down rapidly and lead to the following problems: Inefficiency — water heaters with sediment buildup consume more energy due to the increased strain involved in heating water.
Many homeowners wonder “How often should a hot water heater be replaced?” In a typical situation, you should expect your water heater to last about ten years.
Water leaks are perhaps the most common type of water heater issue you'll face. Any water heater will start to leak eventually, as by nature water will eventually corrode your tank and create microscopic cracks or fractures. However, this isn't always a sign that your tank is what's leaking.
Regardless of what type of water heater tank you have, every system needs regular maintenance. Usually, you need to check your water heater once or twice per year. Gas, electric and tankless water heaters need to be flushed every 6-12 months. This prevents the buildup of sediment, rust and corrosion.
Old water heaters are much less energy efficient, both because they are aging and because standards were lower back then, which could mean more money you're paying each month in energy costs compared to a newer heater. It's generally accepted that most water heaters last an average of about 13 years.
It's generally a good idea to drain your water heater at least once a year, according to both BobVila.com and The Family Handyman.
However, when used and maintained appropriately, it can even last for 15+ years. The tank has an anode rod that attracts corrosive elements in water, protecting its interior lining from corrosion. After using the tank water heater for long (about ten years), the rod gets eaten away and no longer works effectively.
The life expectancy (or useful lifespan) of a Rinnai tankless water heater is up to 20 years. Actual life is impacted by water quality, usage and proper maintenance.
You can expect an electric hot water system to last on average between 10 and 15 years.
Tankless water heaters last between 20-25 years, making them the longest-lasting water heaters on the market. Solar, condensing, and heat pump models all last 15 years or more, whereas point-of-use and tank heaters usually last over a decade.
