  • Frequent Repairs: Frequent repairs can be a sign that it is more cost-effective to replace your boiler. .
  • Inconsistent Heating: If your boiler takes a long time to heat up the radiators, has inconsistent water temperatures, or creates inconsistent temperatures across your property, it could be failing.
  • Leaks and Drips: Any water leaks around your boiler indicate a problem and should be addressed by a professional immediately. .
  • Unusual Noises: Strange noises like banging, kettling, or whistling coming from your boiler indicate that it's not operating optimally.
  • Increasing Energy Bills: Higher utility costs, even with no changes in temperature settings, could be a sign of a less efficient boiler. .
  • Yellow Flame: If the flame in your gas boiler is yellow instead of blue, it could indicate incomplete combustion, a sign that your boiler may need to be serviced or replaced. A yellow flame can also mean a dangerous carbon monoxide leak, so have it checked immediately. .
