How Long Does a Water Heater Last?

Most standard water heaters last between eight and twelve years, depending on the type of water heater, the quality of water, usage, and other factors. A tankless water heater can last even longer as long as it is maintained properly. However, hard water can lessen a water heaters lifespan because it contains minerals that can cause sediment buildup inside the tank. In addition, electric water heaters tend to last longer than gas water heaters.

Factors That Affect a Water Heaters Lifespan

Installation Quality: Proper installation helps to prolong the lifespan of a water heater. A poorly installed water heater is more likely to run into problems early on.
Build Quality: A low-quality water heater will obviously break down faster than a high-quality water heater. This is why it's important to have reliable plumbers help you with water heater installation.
Usage: Heating large quantities of water puts immense stress on the unit, thereby reducing its lifespan. So its important to choose the proper size of water heater to reduce the workload on the unit.
Maintenance: Regular water heater maintenance can extend the lifespan of your water heater and prevent costly emergencies. If you fail to keep up with periodic maintenance checks, your unit will become less effective and eventually break down sooner.

When to Replace a Water Heater

Your Water Heater Is Over 12 Years OldMost water heaters can last from 6 to 13 years. If your water heater is older than 12 years, its best to replace it, even if the current water heater is working properly.
Reduced Hot Water CapacityIf you run out of hot water too fast, that is a sign of significant wear and tear.
Frequent Repairs Frequent water heater repairs are an indication that your unit is on its last leg. Ideally, a water heater should not be repaired more than twice a year. If you find that youre making too many repairs in a year, its time to install a new water heater.
Sediment Buildup Over time, your tank-style water heater may accumulate sediment at the bottom of the tank, leading to inefficiency and accelerated damage. When you notice sediment buildup in the tank, you should consider replacing the unit to reduce energy consumption.
CorrosionSigns of corrosion inside or outside the unit indicates that your water heater is on its last legs and needs to be replaced as soon as possible.
Strange Noises Coming from the Tank Odd noises coming from your water heater are an indicator that your water heater is becoming less effective and needs to be replaced.

If its time to replace your water heater, you want to work with experienced water heater installers who know what they doing. As weve already highlighted, the quality of installation plays a crucial role in the functionality and durability of a water heater. Its important to work with experienced plumbers when it comes to water heater replacement or repair.
