Common Boiler Problems

Boilers can run into various troubles over extended use. Here are some of the usual problems I observe in my work as an HVAC technician:

  • No Hot Water Production: When your boiler doesn’t provide heat, it may be due to a issue with the thermostat, low pressure, or a damaged valve or diaphragm.
  • Unusual Noises: Banging or whistling sounds from the boiler mean trapped air, a accumulation of sludge, or even a damaged part.
  • Decreasing Pressure: A drop in system pressure can hinder your boiler from functioning optimally. Low pressure might be caused to a pressure release valve.
  • Pilot Light Going Out: Older boilers that have pilot lights may suffer issues like flame loss due to drafts, a faulty thermocouple, or a clogged fuel inlet.
  • Control Panel Issues: Sometimes, the thermostat needs recalibration, which hinders temperature regulation.

Simple Boiler Upkeep Advice

Consistent maintenance is crucial to ensuring boiler performance at its best. Here are a few simple maintenance tips that can prevent common issues:

  1. Monitor Boiler Pressure: Your boiler should operate at 1 to 1.5 bars of pressure. If the pressure goes down, use the filling loop to increase the recommended range. Make sure not to exceed recommended levels to keep the system safe.
  2. Air Out Radiators: Air pockets in the radiators impede hot water flow. Use a radiator key to remove the trapped air, and ensure pressure is back to normal.
  3. Clear the Surrounding Area: Debris can get into the boiler, more so if it’s near stored items. Keeping the area clean helps.
  4. Flush the Boiler System: Sediment and sludge tend to settle over time, affecting efficiency. System flushing can help to wash out sludge, which prevents breakdowns.
  5. Book Yearly Boiler Servicing: A yearly inspection by a licensed HVAC technician is vital for identifying small issues before they escalate. A certified technician can evaluate the overall system, repair any wear and tear, and ensure everything is working well.

Signs You Need an HVAC Technician

While many maintenance tasks can be done by homeowners, specific boiler issues require a certified technician. Here are some cases where calling an HVAC professional is necessary:

  • Leaking Boiler: A boiler seeping water points to a significant issue. Moisture problems can result in internal damage, so it’s essential to contact immediately.
  • Ignition Fails: If the pilot light keeps going out, it might be a problem with the thermocouple, gas valve, or ignition system. Only an HVAC technician should repair these components to ensure safety.
  • Persistent Noises: Repeated banging, whistling, or gurgling may mean a clogged pipe. A professional inspection is essential.
  • System Won’t Maintain Pressure: If your boiler is constantly losing pressure, there could be a leak that needs professional diagnosis.
