Typical Boiler Issues
Central heating units can experience various troubles over years. Here are some of the usual concerns I observe in my work as an HVAC technician:
- No Heat or Hot Water: When your boiler won’t produce hot water, it may be due to a malfunction with the thermostat, low pressure, or a failing valve or diaphragm.
- Odd Noises: Clunking or popping sounds from the boiler often indicate trapped air, a accumulation of sludge, or even a damaged part.
- Falling Pressure: A drop in system pressure can affect your boiler from operating optimally. Low pressure might be caused to a leak.
- Pilot Light Won’t Stay Lit: Older boilers equipped with pilot lights may encounter issues like extinguishing due to drafts, a faulty thermocouple, or a clogged fuel inlet.
- Control Panel Issues: Sometimes, the thermostat needs recalibration, which hinders temperature regulation.
Basic Boiler Maintenance Tips
Regular maintenance is essential to maintaining your boiler at its best. Here are a few simple maintenance tips that can keep your boiler in top condition:
- Inspect Boiler Pressure: Your boiler needs to 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. Ensure not to over-pressurize to keep the system safe.
- Bleed the Radiators: Air bubbles in the radiators can reduce heating efficiency. Use a radiator key to remove the trapped air, and check the pressure afterward.
- Remove Obstructions Around the Boiler: Obstructions can get into the boiler, more so if it’s near stored items. Removing obstacles ensures good ventilation.
- Clear Out Sediment: Sediment and debris collect over time, affecting efficiency. You may choose to flush the boiler to wash out sludge, which enhances performance.
- Book Yearly Boiler Servicing: A yearly inspection by a qualified HVAC technician is important for identifying incipient issues before they lead to breakdowns. A certified technician looks at the overall system, address any wear and tear, and make sure everything is in good order.

Signs You Need an HVAC Technician
While many simple fixes can be done by homeowners, certain boiler concerns are best left professional attention. Consider these situations where calling an HVAC professional is necessary:
- Moisture Around the Boiler: A boiler leaking water shows a serious issue. Water issues can lead to internal damage, so it’s safest to call in without delay.
- Pilot Light Won’t Stay On: 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 diagnose these components to ensure safety.
- Unusual Noises: Consistent banging, whistling, or gurgling may mean a pressure problem. A thorough look by an HVAC expert is necessary.
- System Won’t Maintain Pressure: If your boiler is constantly losing pressure, there could be a leak that needs expert attention.
