Boiler Upkeep and Servicing: Advice from an HVAC Technician

As an HVAC technician, I regularly encounter boilers in requiring repair and upkeep. A regularly serviced boiler also performs better but also lasts longer. Here’s a breakdown on boiler repair and maintenance, covering common problems, simple troubleshooting, and when to get in touch with a certified expert.

Typical Boiler Issues

Central heating units can experience various issues over extended use. Here are some of the frequent concerns I see in my work as an HVAC technician:

  • No Heat or Hot Water: When your boiler doesn’t provide heat, it may be due to a malfunction with the thermostat, low system pressure, or a failing valve or diaphragm.
  • Unusual Noises: Clunking or whistling sounds from the boiler often indicate trapped air, a build-up of sludge, or even a damaged part.
  • Falling Pressure: A decline in system pressure can affect your boiler from functioning optimally. Low pressure could be due to a failing part.
  • Pilot Light Won’t Stay Lit: Older boilers that have pilot lights may suffer issues like inconsistent lighting due to drafts, a worn thermocouple, or a blocked pilot orifice.
  • Temperature Settings Issues: Sometimes, the thermostat isn’t working correctly, which hinders temperature control.

Essential Boiler Care

Consistent upkeep is crucial to maintaining your boiler at peak efficiency. Here are my top maintenance tips that can keep your boiler in top condition:

  1. Monitor Boiler Pressure: Your boiler should run around 1 to 1.5 bars of pressure. If the pressure is too low, use the filling loop to increase the correct pressure. Ensure not to exceed recommended levels to prevent stress on the unit.
  2. Air Out Radiators: Air pockets in the radiators can reduce heating efficiency. Use a radiator key to bleed out the trapped air, and check the pressure afterward.
  3. Remove Obstructions Around the Boiler: Debris can get into the boiler, especially if it’s near materials. Removing obstacles helps.
  4. Clean the Boiler’s Components: Sediment and build-up collect over time, reducing heating power. You may choose to flush the boiler to remove sludge, which enhances performance.
  5. Book Yearly Boiler Servicing: A yearly inspection by a certified HVAC technician is important for catching small issues before they lead to breakdowns. A professional technician looks at the overall system, fix any wear and tear, and verify everything is running smoothly.

When to Call a Professional

While many maintenance tasks can be done by homeowners, specific boiler issues require an expert’s help. Here are some cases where calling an HVAC professional is recommended:

  • Moisture Around the Boiler: A boiler leaking water points to a serious issue. Leaks can cause electrical hazards, so it’s best to call in promptly.
  • Pilot Light Won’t Stay On: If the pilot light fails repeatedly, there could be an issue with the thermocouple, gas valve, or ignition system. A professional should handle these components to ensure safety.
  • Unusual Noises: Repeated banging, whistling, or gurgling could suggest a clogged pipe. A thorough look by an HVAC expert is necessary.
  • Constantly Low Pressure: If your boiler is constantly losing pressure, a valve might be malfunctioning that needs expert attention.

Conclusion

Keeping your boiler well-maintained helps ensure a efficient heating system. Consistent care and following maintenance tips can minimize unnecessary repairs.
