Common Boiler Problems

Heating systems can experience specific problems over time. Here are some of the usual issues I encounter in my work as an HVAC technician:

  • Lack of Heat: When your boiler isn’t heating, it may be due to a problem with the thermostat, low pressure, or a damaged valve or diaphragm.
  • Strange Noises: Banging or whistling sounds from the boiler suggest trapped air, a build-up of sludge, or even a worn part.
  • Falling Pressure: A decrease in system pressure can hinder your boiler from operating optimally. Low pressure could be due to a pressure release valve.
  • Pilot Light Won’t Stay Lit: Older boilers equipped with pilot lights may suffer issues like flame loss due to drafts, a faulty thermocouple, or a dirty ignition port.
  • Temperature Settings Issues: Sometimes, the thermostat isn’t working correctly, which hinders temperature adjustment.

Simple Boiler Upkeep Advice

Regular care is key to maintaining your boiler at optimal levels. Here are my top maintenance tips that can help extend the life of your boiler:

  1. Inspect Boiler Pressure: Your boiler typically operate at 1 to 1.5 bars of pressure. If the pressure goes down, use the filling loop to increase the recommended range. Always check not to exceed recommended levels to keep the system safe.
  2. Release Air from Radiators: Air bubbles in the radiators impede hot water flow. Use a radiator key to release the trapped air, and check the pressure afterward.
  3. Remove Obstructions Around the Boiler: Dust might cause inefficiencies, more so if it’s near materials. Maintaining a clear space improves performance.
  4. Clear Out Sediment: Sediment and sludge can accumulate over time, impeding function. You may choose to flush the boiler to eliminate sludge, which prevents breakdowns.
  5. Book Yearly Boiler Servicing: A yearly inspection by a certified HVAC technician is key for catching minor issues before they become serious. A trained technician can evaluate the overall system, address any wear and tear, and make sure everything is working well.

When a Pro is Necessary for Boiler Issues

While some boiler checks can be done by property owners, specific boiler issues require an expert’s help. Below are situations where calling an HVAC professional is a must:

  • Water Leaks: A boiler leaking water shows a significant issue. Leaks can result in safety risks, so it’s essential to contact immediately.
  • Burner Won’t Ignite: If the pilot light fails repeatedly, there could be an issue with the thermocouple, gas valve, or ignition system. Certified technicians should repair these components to ensure safety.
  • Unusual Noises: Frequent banging, whistling, or gurgling may mean a pressure problem. A licensed checkup is recommended.
  • System Won’t Maintain Pressure: If your boiler is constantly losing pressure, there could be a leak that needs expert attention.

Conclusion

Keeping your boiler well-maintained is essential for a long-lasting heating system. Consistent care and following maintenance tips can minimize unnecessary repairs.
