Common Boiler Problems

Heating systems can experience various troubles over years. Here are some of the frequent issues I observe in my work as an HVAC technician:

  • No Heat or Hot Water: When your boiler isn’t heating, it may be due to a issue with the thermostat, low system pressure, or a failing valve or diaphragm.
  • Unusual Noises: Banging or popping sounds from the boiler mean 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 efficiently. Low pressure can happen to a pressure release valve.
  • Pilot Light Extinguishes: Older boilers using pilot lights may encounter issues like extinguishing due to drafts, a damaged thermocouple, or a clogged ignition port.
  • Thermostat Issues: Sometimes, the thermostat isn’t working correctly, which hinders temperature control.

Essential Boiler Care

Consistent maintenance is essential to ensuring boiler performance at its best. Here are some basic maintenance tips that can prevent common issues:

  1. Inspect Boiler Pressure: Your boiler needs to operate at 1 to 1.5 bars of pressure. If the pressure drops, use the filling loop to bring it back up to the recommended range. Ensure not to go above the suggested range to avoid damage.
  2. Bleed the Radiators: Air pockets in the radiators can reduce heating efficiency. Use a radiator key to bleed out the trapped air, and ensure pressure is back to normal.
  3. Keep the Boiler Area Clear: Obstructions may clog parts, especially if it’s near stored items. Keeping the area clean helps.
  4. Clear Out Sediment: Sediment and build-up tend to settle over time, impeding function. System flushing can help to wash out sludge, which improves efficiency.
  5. Book Yearly Boiler Servicing: A yearly inspection by a qualified HVAC technician is vital for spotting incipient issues before they escalate. A professional technician will assess the overall system, fix any wear and tear, and verify everything is working well.

Signs You Need an HVAC Technician

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

  • Water Leaks: A boiler dripping water indicates a significant issue. Leaks can lead to electrical hazards, so it’s best to call in promptly.
  • Ignition Fails: If the pilot light keeps going out, you could be dealing with an issue with the thermocouple, gas valve, or ignition system. Certified technicians should handle these mechanisms to fix the issue.
  • Persistent Noises: Consistent banging, whistling, or gurgling may mean a pressure problem. A professional inspection is essential.
  • Constantly Low Pressure: If your boiler is drops in pressure often, there could be a leak that needs professional diagnosis.
