Accessing warm water is more than a luxury in the colder months, and surviving without it may be incredibly difficult. However, people take it for granted until water heaters cause problems. Learning how long water heaters last can help you plan for future replacements instead of waiting for the issues to arise.
How Long Will My Water Heater Last?
Tank-style and tankless water heaters are two main types of water heaters that are used in residential buildings. The life expectancy of water heaters depends on various factors, such as their size, how well they are maintained, and how much you use them.
The standard size of a water tank is usually 40 gallons, which lasts between 10 and 15 years. However, a larger tank comes in a 50-gallon size, with a life expectancy of up to 20 years.
If you live in an area with hard water, the lifespan of a standard water heater may be shorter because hard water contains magnesium and calcium. These minerals cause scale buildup on the tank parts, which can clog or damage various parts.
When more and more scale builds over time, the water heater’s performance will decrease, making it less efficient.
- The life Span of a Tank-Style Water Heater
A tank-style water heater or conventional water heater is a commonly used type of water heater in most homes. It typically lasts 8-12 years when operated and maintained correctly. With regular upkeep and maintenance, it can last for more than 15 years. However, its longevity depends on your water’s hardness, how often you use it, and your climate.
- Life Span of Tankless Water Heater
Tankless water heaters are an excellent option for a small to medium-sized home. They are not commonly used in most homes. Typically, the life expectancy of a tankless water heater is about 20 years, with proper care and regular maintenance. If you maintain it appropriately, it can last for up to 30 years.
When Should You Replace Your Old Unit?
Water heaters become less efficient and consume more energy as they age. That’s why the manufacturers recommend replacing your water heaters every ten years. Newer models tend to consume less energy, thanks to the technological advancements.
They can transfer heat more efficiently than older models and are better insulted. Replacing every 10 years can help you save hundreds of dollars on your electric bill each year. Outdated units may lead to leaky values, slow water flow, and corrosion, leading to material deterioration. If your water heater shows such signs and your unit is less than 10 years old, it may need to be replaced with a newer model.
You can consult a qualified plumber to determine whether to replace your unit. You can even schedule an annual maintenance to understand better when you should invest in a new unit and check its performance.
The Bottom Line:
The life expectancy of a water heater depends on many factors, including the frequency of its usage, the climate you live in, and water hardness. That’s why it is impossible to precisely tell a given water heater’s lifespan. However, most experts say that the average life expectancy of a water heater is between 12-25 years. The efficiency of conventional water heaters may begin to decline after ten years of age. Contact us today.
