Can gas ducted heating cause carbon monoxide poisoning?

Yes, they can. This can happen when the combustion process is incomplete, producing large quantities of carbon monoxide. This is the biggest risk in gas ducted heaters that have been left unserviced or are in a faulty condition. 

Issues that can lead to carbon monoxide leaks include poor air-to-gas ratios, obstruction of the flame, incorrect gas operating pressures, bad burners, or cracks in the heat exchanger. When such leaks take place in an enclosed space, dangerous levels of carbon monoxide can build up. 

The best way to reduce the risk of carbon monoxide poisoning caused by faulty gas ducted heaters is to ensure regular servicing. You can check for this by visually inspecting the heater before turning it on in winter, and each month after to look for visible damage, to see if the flame is visible beyond the top surface of the tile, the pilot lights and main burners are producing a blue flame, not yellow or red, or if it emits a strange smell. If any of these issues are the case, call a professional for a service immediately. It is also vital to ensure proper ventilation in the room to help reduce any risk of carbon monoxide poisoning.

What Our Customers Are Saying
  • Excellent service & workmanship

    This is my second system that Coldflow have installed and I'm very happy with the result.
    2 head air conditioning system installation was quick and tidy. Even though the cassettes are more complicated and involved to install. All the guys cleaned up after themselves and took all the rubbish away. Excellent service and workmanship, even when it rained and then heat (it's Melbourne).
    System work a treat, just waiting for the heatwave to arrive. Great work by the team.

  • Again, very happy with the service

    I was extremely happy with the service provided by Coldflow.
    I had a ducted cooling system installed. The team turned up on time and completed the job the same day. The guys were courteous and completed the job with a minimum of fuss and disruption. The workmanship was excellent and all ducts were located as per our agreement. They placed drop sheets wherever required and cleaned up after completion. Again was very happy with the service provided by all the crew.
