Is It Time to Go Tankless? 7 Signs You Should Upgrade Your Water Heater

Your water heater might not be something you think about every day—until it stops doing its job. If you’ve been experiencing issues with hot water in your home, your system might be trying to tell you something. Here are seven signs it might be time to retire your old tank and upgrade to a tankless water heater.

1. Rust-Colored Water

If your hot water has a brownish tint or metallic taste, your tank may be rusting from the inside out. This is a major red flag that the unit is nearing the end of its lifespan. Rust compromises water quality and can lead to serious leaks.

2. Leaks or Puddles Around the Tank

Aging water heaters are more prone to cracks and corrosion. If you see water collecting around the base of the tank, it could be the result of expanding metal or internal failure. Leaks can cause water damage and mold if left unchecked.

3. Strange Noises

Popping, rumbling, or banging noises are often caused by sediment buildup at the bottom of the tank. As water is heated, this sediment hardens and causes the unit to work harder, reducing efficiency and increasing wear and tear.

4. Running Out of Hot Water

If your household is consistently running out of hot water—especially during peak usage—it may be a sign your current system can’t keep up. Tank-style heaters have a limited capacity, while tankless water heaters provide hot water on demand.

5. High Utility Bills

Traditional water heaters continuously heat stored water, even when it’s not in use. This standby heat loss can drive up your energy bills. A tankless system only heats water as needed, which can result in significant savings over time.

6. Fluctuating Water Temperature

Inconsistent hot water—especially if it goes cold suddenly—is a common symptom of an aging or malfunctioning water heater. A tankless model provides a steady and reliable temperature for as long as you need it.

7. It’s Over 10 Years Old

Most traditional water heaters last about 8 to 12 years. If yours is nearing or past that range, it’s smart to start exploring your options before you’re faced with an emergency replacement.
