Signs You Need a New Water Heater

Your water heater works hard behind the scenes, but like any appliance, it won’t last forever. Knowing the warning signs of a failing system can help you avoid an unexpected breakdown. If you notice any of the issues below, it might be time to start planning for a water heater replacement:

  • Inconsistent or insufficient hot water: If your hot water runs out too quickly or fluctuates in temperature, it could signal a failing heating element or sediment buildup.
  • Unusual noises: Rumbling or banging sounds may indicate mineral buildup inside the tank.
  • Rusty or discolored water: This can be a sign of internal corrosion, especially if it’s coming only from your hot water taps.
  • Leaks around the base: Water pooling at the bottom of the tank usually means the tank is cracked or failing.
  • Frequent repairs or service calls: If your current unit keeps breaking down, replacing it could be more cost-effective than continuing to repair it.
  • System is over 10 years old: Most traditional water heaters last 8–12 years. Older units are less efficient and more prone to failure.

Water Heater Installation FAQs

Standard tank water heaters generally last between 8 to 12 years, while tankless models can last 15 to 20 years with proper maintenance. Regular inspections and flushing can help extend the life of your unit.

Tank water heaters are more affordable upfront. Tankless units cost more initially but offer energy savings and an endless supply of hot water, making them ideal for those looking for efficiency.

Yes, but it may require some modifications to your plumbing or electrical system. A professional can evaluate your current setup and help you understand what changes, if any, would be needed to accommodate a tankless unit.
