Indicators that Your Navien Boiler Needs Necessary Maintenance or Replacement

While Navien boilers are designed to have a long lifespan but require maintenance and occasional repairs. To determine if your Navien boiler is due for maintenance or replacement, keep an eye out for the following indicators:
- Unusual Sounds: Any unfamiliar noises emanating from your boiler could suggest a problem. Grinding or whistling sounds might indicate a mechanical issue while hissing or banging sounds could imply a blocked pipe.
- Inconsistent Heating: If your boiler isn’t heating your home uniformly, it could signify an obstruction in the system or faulty boiler performance.
- Elevated Energy Bills: An inefficient boiler will require more energy to function, leading to a rise in your energy bills.
- Age: If your boiler is over 15 years old, it’s likely time to consider a replacement. Older models are frequently less effective and may not function as well.
- Water Leakage: A leaking boiler is a clear sign of a problem.
- Unusual Odors: If your boiler is emitting an unusual smell, it could suggest a serious issue.
- Poor On/Off Functionality: If your boiler isn’t turning on or off correctly, it may require maintenance or replacement.
