Signs Your Boiler Is In Need Of Repairs or Replacement

Your boiler, just like any other type of machinery, needs to be regularly maintained to ensure that it's in proper working order. Some key signs to look out for that signal the need for repairs or a replacement include:

  • Age: With proper maintenance, boilers are expected to last at least 15 years or longer. Some boilers can last even up to 50 years or longer, but even with decent annual maintenance, there are other faults that can make a boiler breakdown.
  • Increase in Energy Usage: Be mindful of any increases in energy expenses. If a boiler requires constant servicing, the system has likely become less efficient. A noisy unit also may be a sign that it’s time for an upgrade.
  • Constant Maintenance: This is a clear sign that a boiler is in need of being replaced.
  • Discoloration: Yellow flames on gas burners and black soot on oil boilers indicate that the fuel is not burning properly and is creating carbon monoxide. It’s critical to have a carbon monoxide detector in your home.
  • Leaks: A boiler that leaks or requires additional make-up water could be nearing the end of its lifecycle. By replacing the existing unit, homeowners or building managers/owners can avoid costly floods and critical boiler or property damage.
