Is It Time to Replace Your Water Heater?

Tankless water heaters are known for their durability, but like any appliance, they have a finite lifespan. Recognizing the signs of failure can help you avoid a sudden and complete loss of hot water. Alternatively, if you're still using an old tank-style heater, these points may signal it's the right time to make the switch.

Key Indicators for Replacement:

1. Inconsistent Water Temperatures: If your water fluctuates between hot and cold, or if it can't be heated sufficiently, the heating element or internal sensors may be malfunctioning.
2. Reduced Water Flow: A noticeable drop in water pressure from your hot water taps can indicate a buildup of mineral scale inside the unit, restricting flow and straining the system.
3. Frequent Error Codes: Modern tankless units display error codes to signal problems. If you're constantly needing to reset your unit or are seeing persistent errors, a replacement may be more cost-effective than repeated repairs.
4. Strange Noises: Rumbling, popping, or whining sounds often point to sediment buildup or mechanical stress within the heater.
5. Visible Leaks or Corrosion: Any sign of water leaking from the unit or corrosion on its fittings is a serious issue that demands immediate attention and usually warrants a full replacement.
6. Age: While a well-maintained tankless unit can last over 20 years, the lifespan of a traditional tank heater is typically only 10-15 years. If your system is approaching or has surpassed its expected service life, proactively replacing it is a wise decision.
   1. Endless Hot Water: A tankless heater heats water on demand as it flows through the unit. This means you’ll never run out of hot water again, even with simultaneous uses like running the dishwasher while someone showers.
   2. Superior Energy Efficiency: Traditional tanks constantly burn energy to keep dozens of gallons of water hot, 24/7. This is known as standby heat loss. Tankless systems only consume energy when a hot water tap is opened, leading to substantial savings on your monthly utility bills. A detailed Home Energy Audit can quantify these potential savings.
   3. Longer Lifespan: With proper care and routine Plumbing Maintenance, a tankless water heater can last 20 years or more, nearly double the lifespan of the average storage tank heater.
   4. Space-Saving Design: Tankless units are compact and wall-mounted, freeing up valuable floor space in your garage, closet, or utility room where a bulky tank used to stand.
      1. In-Home Consultation and Proper Sizing: We start by assessing your home’s unique hot water requirements. This includes evaluating the number of bathrooms, appliances, and your family’s usage patterns. We calculate the required flow rate and temperature rise to recommend a unit that is perfectly sized for your needs—never too small to keep up or too large to be inefficient.
      2. Safe Removal of the Old Unit: Our licensed plumbers will safely disconnect and drain your old water heater, whether it’s a tankless or traditional model. We handle the proper disposal of the old unit in accordance with local regulations, leaving your space clean and ready for the new installation.
      3. Expert Installation and System Integration: This is where professional expertise is critical. We securely mount the new tankless heater and make all necessary connections. This may involve upgrading gas lines to meet the higher demand, re-routing water pipes for optimal flow, and installing a new ventilation system to ensure safe exhaust. Every connection is checked for integrity to prevent leaks or safety hazards.
      4. System Testing and Calibration: Once installed, we don’t just turn it on and leave. We thoroughly test the system, firing up the unit and checking the water temperature at various faucets throughout your home. We calibrate the temperature settings to ensure both comfort and efficiency, and verify that all safety features are functioning correctly.
      5. Customer Walkthrough and Education: We conclude every replacement by walking you through your new system. We’ll show you how to operate it, explain any maintenance you can perform, and answer all of your questions. Our goal is for you to feel completely confident and comfortable with your new tankless water heater.
