Your water heater may have a tank to hold the water while it is being heated. Most commonly, when the tank gives out the whole heater has to be replaced, so you may wonder how long that will take. When choosing a replacement, you might consider a tankless water heater, that won’t corrode or give out the same way that versions with a tank will. Here is what you need to know about how long a hot water tank lasts. 

How Long Should A Hot Water Tank Last? 

The lifespan of a hot water tank depends on how hard your water is, and the quality of the anode rod inside the tank (if there is one). The harder the water, the sooner the tank will wear down, as the materials in the water wear down the metal in the tank. 

Anode rods interfere with the reaction between the hard water and the tank. However, they will only last so long. Once they are worn out, the hard water will begin to affect the metal of the tank and the process of corrosion will begin. 

Thankfully, this process does take some time. The average lifespan of a hot water tank is 10 to 15 years. Much depends on the brand and model of water heater you purchased, as they may be made from different materials of different thicknesses. Fibreglass tanks will last longer than steel ones, and thicker tanks will also last longer than thinner ones.

How Long Do Tankless Water Heaters Last? 

If you’re worried about water heater lifespan, then a tankless water heater might be for you. As the name suggests, they do not have a tank. Instead, they heat up the water in your pipes directly and quickly. These appliances last for much longer, at roughly 20 years, and even longer if you keep it properly maintained. 

Should I Replace My Water Heater?

Water heaters need to be replaced when their tank breaks or, ideally, just before that happens as a break can mean a mess on your floor. Consider these signs that it is time to replace your water heater: 

  • Age: Once a water heater is past its lifespan of 10 to 15 years, it is time to get it replaced. 
  • Leaks: Any water trickling or gushing out of the tank means that there is a gap in the tank that can’t be fixed. 
  • Rust: Rust will soon create a leak, and it also cannot be fixed. 
  • Poor performance: If your water heater isn’t making hot water, it needs repair or replacement.
