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.
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.
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.
Based on the manufacturer's suggested service life, the life expectancy of a water heater is about eight to 12 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.
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.
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. Check your water heater's warranty for the most accurate timelines.
If not regularly flushed, your water heater can corrode more quickly. The sediment can also block or clog the pressure and relief valve (which helps keep your water heater from exploding).
If your water heater is more than 10 years old, it's probably reaching the end of its lifespan. Most conventional electric hot water tanks will last 10-15 years maximum. Gas-powered hot water tanks usually breakdown after 8-10 years, while tankless water heaters can last over 15 years with regular maintenance.
If your water isn't quite as hot as it once was, and it feels lukewarm, it could mean that you need to replace your water heater. Pay attention to the water pressure as well – lukewarm water and low pressure water is a sign that your water heater needs replacing.

Flush the tank regularly
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.
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.
Labor Cost to Install a Hot Water Heater
Labor costs could be as low as $150 or up to $1,000 or more. They vary based on the installer's hourly rate, the size and type of water heater and the location of the installation.
You should be aware that the cylinder installed in your property is a pressurised container and will require regular maintenance just like a gas boiler. An annual check is vital to ensure your safety and must be carried out by a qualified engineer.
The best way to protect your investment is to have your water heater serviced annually by a licensed plumber. A good plumber will conduct a full inspection for rust, leaks and other problems, test the thermostat and valves, replace the anode rod to prevent corrosion and flush the tank.

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.
