Understanding the Lifespan of Water Heaters
The average lifespan of a water heater varies considerably based on several key factors that homeowners need to understand.
We typically see traditional tank-type heaters lasting 8-12 years, while tankless models can extend to 20 years with proper care.
Water quality plays an essential role in longevity, as hard water accelerates corrosion.
We’ve found that regular maintenance, including annual flushing and anode rod replacement every 3-5 years, greatly extends a unit’s life.
Additionally, proper installation and consistent temperature regulation at 120°F help maximize the system’s durability.
Environmental conditions and usage patterns will also impact your water heater’s lifespan.
Key Signs of an Aging Water Heater
Let’s look at two critical indicators that your water heater needs attention: rust and performance issues.
We recognize that rust appearing in your hot water or around pipe fittings is a serious warning sign of internal corrosion that shouldn’t be ignored.
When these rust signs combine with declining performance, such as inconsistent temperatures or increased energy bills, it’s time to evaluate whether repairs are worth the investment.
Rust and Corrosion Signs
Recognizing rust and corrosion signs in your water heater can help you determine whether it’s time for repairs or replacement.
We’ll help you identify the key indicators of corrosion in your system.
Check these common warning signs:
- Rusty or reddish-brown water when running hot water
