How Long Do Water Heaters Last? Signs It’s Time to Replace Yours
Water heaters last an average of eight to twelve years with proper maintenance, but their lifespan can vary depending on the type of water heater repair. Whether it’s a traditional or instantaneous water heater, they will eventually need to be replaced.
Below, we’ll analyze the average lifespan of water heaters by type and the most common problems that might indicate the need for replacement.

Average Lifespan of Water Heaters
The lifespan of a water heater can vary depending on the type of system.
• Tank water heaters can last an average of eight to twelve years.
• Instantaneous water heaters can last an average of 15 to 20 years.
• Solar water heaters can last an average of 10 to 25 years.
• Hybrid water heaters can last an average of 13 to 15 years.
In addition to the type of system, the age and quality of the unit can affect the longevity of the water heater. That’s why proper water heater maintenance is essential to prolonging its life.
4 Signs Your Water Heater Needs Replacement
Several signs may indicate the need to replace your water heater. If you experience any of the following problems, it’s advisable to consult a professional plumber to diagnose the problem and determine if your water heater needs to be replaced.
1. Leaky Water Heater
Risk Level: High
A leaky water heater is a telltale sign that something is wrong. A myriad of problems can cause a water heater to leak, such as cracks in an old tank or corrosion and sediment buildup. It’s important to diagnose the source of the leak and act quickly because, if a leak goes undetected, it can lead to more serious problems, such as mold growth and property damage.
If you notice small leaks coming from the safety valve or drain valve, they can be fixed with a simple component replacement. However, if you notice leaks coming from the tank itself, they could be due to sediment buildup and corrosion.
Solution: Have a professional determine the source of the leak and whether it’s accompanied by other problems, such as rusty water or an aging tank. If there are no other problems, consider replacing the faulty component. If the leak is coming from the tank, replacing the water heater may be the safest and most reliable solution.
2. You’ve found rusty water
Risk level: High
If you’ve noticed rusty or discolored water around the water heater or dripping from a faucet, it could indicate deterioration within the tank. Not only can this contaminate the water supply, but corrosion can weaken the tank, causing cracks and leaks.
Solution: Before considering replacing the water heater, contact a professional to diagnose the source of the rusty water and determine the best course of action. If the rust is coming from the water heater, replacing it may be the most reliable and cost-effective solution.☎️ Call us 24/7 at 01902933956 !
3. The water heater is old
Risk Level: High
Even if you haven’t noticed any signs of concern and your water heater is more than 8-12 years old, it may be time to replace it. Waiting too long could cause other problems or unexpected failures.
To determine the age of your water heater, check the water heater warranty or the label on the tank for the manufacturing date. If you don’t see the date, search online using the brand and serial number.
Solution: Consider replacing your water heater repair to avoid further problems that could cause water damage and potential safety risks.
4. You hear a rumbling noise
Risk Level: Medium
Popping, rumbling, and gurgling noises coming from your water heater are often signs of sediment buildup. Over time, minerals in the water build up and settle to the bottom of the tank. When your water heater turns on and off, it displaces sediment, causing the rumbling noise.
The solution: Drain the water heater to remove sediment buildup. If you still hear a knocking noise after draining the water, it could be a sign of another problem. Contact a service technician to diagnose the source of the noise and determine if repairs or replacements are necessary.
How do I know when my water heater is failing?
Several signs can indicate a water heater failure, including:
• Advanced age, typically over 8-12 years
• Rusty water or rust around the tank
• Gurgling or popping sounds coming from the unit
• Visible leaks coming from the water heater
• Fluctuations in water temperature
• Inability to produce hot water
