Boiler Troubleshooting in Vancouver

In the cold Vancouver climate, a well-functioning boiler is crucial for comfort and efficiency. ROMA Heating & Cooling, with over two decades of expertise in HVAC services, offers this essential guide to troubleshooting common boiler issues. Whether you\’re facing minor hiccups or major malfunctions, this guide provides valuable insights into identifying and resolving boiler problems, ensuring your home remains warm and cozy throughout the harsh winter months.

Common Boiler Problems

Boilers are complex systems that can encounter a variety of issues, particularly without regular maintenance. Some of the most frequent problems experienced by Vancouver residents include:

  • No Heat or Hot Water: Potential causes could be broken diaphragms and airlocks, failure of motorized valves, issues with the thermostat, or low water levels.
  • Leaking and Dripping: Commonly caused by a broken internal component, such as a pressure valve or pump seal. If the leak originates from the pressure valve, the boiler pressure might be too high.
  • Strange Noises: Such as whistling, gurgling, or banging, typically caused by air in the system, low water pressure, or imminent pump failure.
  • Pilot Light Goes Out: Can be caused by a broken thermocouple, which stops the gas supply, or a draught blowing the light out, or a buildup of deposits in the pilot light.
  • Losing Pressure: If your boiler frequently loses pressure, it might be due to a water leak in the system, the pressure relief valve needing replacing, or due to recently bled radiators.

Troubleshooting Steps

When you encounter an issue with your boiler, follow these steps before calling in the professionals:

  1. Check the Thermostat: Ensure that it is set to the correct settings and is operational as it controls the temperature of the boiler.
  2. Inspect the Pressure Gauge: The normal pressure level should be between 1.0 and 1.5 bars. If it’s below, re-pressurizing the system may be necessary.
  3. Reset the Boiler: Sometimes, simply resetting the boiler can solve the problem. Refer to the manufacturer\’s instructions for how to reset your specific model.
  4. Examine the Pilot Light and Ignition: For older boilers, make sure the pilot light is lit. For newer models, check the ignition mechanism.
  5. Look for Error Codes: Modern boilers display error codes that can help identify the specific issue.

When to Call a Professional

If basic troubleshooting does not resolve the problem, it\’s time to call in the experts from ROMA Heating & Cooling. Here are signs that professional help is needed:

  • The boiler continues to display an error code after resetting.
  • There is evidence of a water leak from the boiler.
  • You smell gas or other chemical odors near the boiler.
  • Repeated issues occur despite regular troubleshooting efforts.

5 Tips for Better Health of Your Boiler

Maintaining your boiler can extend its lifespan and ensure it operates efficiently. Here are five tips to keep your boiler in top condition:

  1. Annual Service: Have your boiler serviced annually by a qualified technician to catch any potential issues early.
  2. Check for Drafts: Ensure that there are no drafts that could extinguish the pilot light in older boilers.
  3. Bleed Radiators: Regularly bleed your radiators to remove any air trapped in them, which can affect heating efficiency.
  4. Monitor Water Pressure: Regularly check the boiler\’s pressure gauge to ensure it remains within the recommended range, adjusting as necessary.
  5. Keep the Area Clear: Keep the area around your boiler clear of clutter to ensure adequate ventilation and reduce the risk of overheating or blockages.


Q1: How often should I have my boiler serviced? A1: It is recommended to have your boiler serviced annually to ensure it\’s running safely and efficiently.

Q2: What should I do if my boiler leaks water? A2: If your boiler is leaking water, turn off the water supply and call a professional technician to assess and repair the issue.

Q3: Can I replace parts of my boiler myself? A3: It\’s best to have a certified technician replace any parts, as incorrect installation can lead to further issues or void warranties.

Q4: Why is my boiler making a banging noise? A4: Banging noises are often due to air in the system or a buildup of limescale on the heat exchanger. A professional cleaning may be required.

Q5: What does it mean if my boiler\’s pressure is too high? A5: A high pressure can be due to several reasons including an overfilled system or a malfunctioning pressure relief valve. It’s crucial to have it checked by a professional to prevent operational issues.
