A water heater ensures a constant supply of hot water to a household. Homeowners want to get the most out of their water heaters and wish it lasts for as long as possible. However, like other plumbing appliances, a water heater also comes with a life expectancy. Though a water heater is expected to last for several years, several factors affect its longevity.
Understanding the factors that affect the water heater’s lifespan helps homeowners add a few more years of functional life to their current units. It prolongs the time between replacements, avoids leaks and other issues, and informs the decision about a new water heater.
Some factors that influence a water heater’s longevity include:
TYPE OF WATER HEATER
Several water heaters are available in the market, and each has a different lifespan. A standard tank gas water heater lasts for about 8-12 years, while a storage electric water heater has a lifespan of 10-15 years. Modern tankless water heaters have a longer life expectancy. Gas and electric tankless water heaters can last well over 20 years when maintained regularly.
QUALITY OF THE UNIT
Water heaters have varying quality levels. The water heater’s structure and parts’ quality significantly affect its longevity. A superior quality, high-end water heater model lasts longer than one made using inferior materials. It also comes with more extended warranties. A professional can assist in choosing a high-quality water heater.
INSTALLATION
How and where the water heater is installed influences its life expectancy. Even the best quality water heater will fail to function correctly or have a long service life if the installation is faulty. An improperly installed water heater will experience issues soon after its installation. Water heaters positioned in areas with frequent temperature fluctuations, like garages or crawl spaces, wear out faster. Always install the water heater in a temperature-controlled environment for longer life.
WATER QUALITY
The type of water running through the heater also determines its lifespan. Hard water decreases the performance and longevity of a water heater. It leads to sediment and scale accumulation, which reduces the water heater’s ability to heat the water properly and its overall efficiency.
WATER PRESSURE
High water pressure can significantly damage the water heater and even cause it to explode. When purchasing a water heater, ensure it has a pressure-reducing valve pre-installed. It regulates the water pressure inside the heater and prevents issues.
MAINTENANCE FREQUENCY
Regular maintenance and timely repairs keep the water heater in top condition, prevent major issues, and increase its lifespan by a few years. Flush the tank when needed, clean it regularly, replace the anode rod every five years, test the temperature relief valve annually, and hire a professional to inspect the unit for leaks, corrosion, and damaged components periodically to increase the water heater’s life.
SIGNS A WATER HEATER NEEDS REPLACEMENT
Here are a few signs indicating the need for water heater replacement:
- Gurgling, cracking or popping sounds
- Water puddles around the tank
- Rusty water
- It is over ten years old and showing signs of failing
- Faulty drain valve
- No hot water
Replace the water heater if it is nearing the end of its expected lifespan or exhibiting warning signs of failure. Purchase a new, energy-efficient heater and take adequate measures to ensure it lasts longer.
