Signs You Need to Replace Your Water Heater

If your water heater is over 10 years old or struggling to keep up with your hot water demands, it may be time for a replacement. We offer professional water heater assessments and honest recommendations to help you avoid costly repairs and water damage.

Some common signs to watch out for that indicate it’s time to get a new water heater include:

  • Rusty or discolored water: If your hot water comes out rusty or cloudy, it could indicate corrosion inside the tank, an early sign of system failure.
  • Inconsistent hot water: Fluctuating water temperatures or running out of hot water too quickly often indicate a failing heating element or tank issue.
  • Leaks around the tank: Any pooling water near the base of your heater suggests a leak and potential tank rupture, requiring immediate attention.
  • Strange noises: Popping, banging, or rumbling sounds may indicate sediment buildup inside the tank, which can reduce efficiency and lead to damage.
  • Frequent repairs: If your system needs multiple repairs quickly, investing in a new unit may be the more cost-effective option in the long run.

Choosing the Best Water Heater for Your Home

Selecting the right water heater starts with understanding your household’s needs. Our team will walk you through your options and recommend the best system for your budget and lifestyle. Types of water heaters we install include:

  • Traditional tank water heaters: These systems store and heat water in a large tank and are available in gas or electric models. They are great for families with steady water usage.
  • Tankless water heaters: Tankless units heat water on demand without storage. They are energy-efficient and compact, making them ideal for homes with limited space or high energy-saving goals.
  • Electric water heaters: Reliable and easy to install, electric models are a good choice for homes without natural gas.
  • Gas water heaters: Gas systems are typically more energy-efficient for high-demand households but require natural gas line access.
  • High-efficiency water heaters: These ENERGY STAR®-rated models reduce energy bills while delivering consistent hot water.
