How often should I replace my water heater?

The typical lifespan of a water heater is about 8-12 years, though this can vary depending on several factors:

  1. Type of Water Heater:

  • Tankless water heaters generally last longer, around 20 years or more.

  • Conventional tank water heaters usually last between 8-12 years.

  1. Water Quality:

  • Hard water can shorten the lifespan of your water heater due to mineral buildup.

  • Using a water softener can help extend the lifespan.

  1. Maintenance:

  • Regular maintenance, such as flushing the tank annually to remove sediment buildup and inspecting the anode rod every few years, can help extend the lifespan.

  1. Usage:

  • Higher usage means more wear and tear, potentially reducing the lifespan.

  1. Installation Quality:

  • Proper installation by a professional can ensure your water heater operates efficiently and lasts longer.

Signs that it might be time to replace your water heater include:

  • Age: If it's approaching or past its expected lifespan.

  • Rusty Water: Indicates corrosion inside the tank.

  • Noises: Rumbling or banging sounds suggest sediment buildup.

  • Leaks: Water pooling around the base is a clear sign of a problem.

  • Inefficiency: Increasing energy bills or inconsistent hot water supply.

Regularly inspecting your water heater and performing routine maintenance can help you determine when it’s time for a replacement.
