Common Boiler Problems

Boilers can run into various problems over years. Here are some of the common issues I observe in my work as an HVAC technician:

  • No Hot Water Production: When your boiler isn’t heating, it may be due to a malfunction with the thermostat, low system pressure, or a failing valve or diaphragm.
  • Unusual Noises: Banging or gurgling sounds from the boiler suggest trapped air, a presence of sludge, or even a broken part.
  • Falling Pressure: A decrease in system pressure can affect your boiler from operating optimally. Low pressure can happen to a leak.
  • Pilot Light Extinguishes: Older boilers equipped with pilot lights may encounter issues like extinguishing due to drafts, a faulty thermocouple, or a dirty ignition port.
  • Control Panel Issues: Sometimes, the thermostat needs recalibration, which hinders temperature control.

Basic Boiler Maintenance Tips

Routine maintenance is key to maintaining your boiler at its best. Here are a few simple maintenance tips that can prevent common issues:

  1. Check Boiler Pressure: Your boiler typically run around 1 to 1.5 bars of pressure. If the pressure is too low, use the filling loop to bring it back up to the recommended range. Always check not to go above the suggested range to keep the system safe.
  2. Release Air from Radiators: Air pockets in the radiators can reduce heating efficiency. Use a radiator key to release the trapped air, and check the pressure afterward.
  3. Keep the Boiler Area Clear: Debris can get into the boiler, more so if it’s near materials. Maintaining a clear space helps.
  4. Flush the Boiler System: Sediment and debris can accumulate over time, affecting efficiency. A professional can flush the system to eliminate sludge, which improves efficiency.
  5. Book Yearly Boiler Servicing: A yearly inspection by a certified HVAC technician is vital for identifying small issues before they lead to breakdowns. A professional technician looks at the overall system, repair any wear and tear, and ensure everything is running smoothly.

Signs You Need an HVAC Technician

While basic boiler checks can be done by residents, many boiler problems are best left professional attention. Below are cases where calling an HVAC professional is recommended:

  • Leaking Boiler: A boiler seeping water indicates a major issue. Leaks can lead to electrical hazards, so it’s best to get a professional without delay.
  • Burner Won’t Ignite: If the pilot light fails repeatedly, it might be a problem with the thermocouple, gas valve, or ignition system. Only an HVAC technician should diagnose these components to prevent hazards.
  • Persistent Noises: Consistent banging, whistling, or gurgling often indicates a clogged pipe. A licensed checkup is necessary.
  • System Won’t Maintain Pressure: If your boiler is drops in pressure often, there could be a leak that needs expert attention.

Conclusion
