Flued gas space heaters prone to carbon monoxide poisoning

Energy Safe Victoria is urging Victorians, including those in Wyndham, using open flued gas space heaters to service them after every two years to reduce chances of carbon monoxide poisoning.

Energy Safe’s Be Sure campaign, which calls for open flued gas space heaters to be serviced every two years, was launched following the 2017 death of Sonia Sofianopoulos who suffered carbon monoxide poisoning in her home.

Servicing should be carried out by a Type A licensed gasfitter. Check that they are accredited before starting work.

The energy safety regulator is using this year’s Be Sure campaign to highlight the particular risk to Victorians operating open flued gas space heaters in properties that have recently been renovated or weather sealed.

Open flued gas space heaters are considered old technology, designed to draw air from the within the home for combustion.

However, units that are not serviced or are faulty can cause carbon monoxide leakage created by a negative pressure environment, which occurs when operating bathroom and kitchen exhaust fans with little-to-no ventilation.

Energy Safe has developed a video explaining negative pressure.

New and renovated homes are generally better insulated with reduced ventilation, which can impact the safe operation of open flue gas space heaters, potentially causing carbon monoxide to leakage into a home.

In July 2022, Energy Safe also banned the sale and supply of new open flued gas space heaters that do not meet new Australian Standards.

This Standard requires newly manufactured open flued gas space heaters shut down within 15 minutes if the appliance is operating in a negative pressure environment, which could lead to carbon monoxide spillage.

Energy Safe CEO Leanne Hughson said the carbon monoxide leakage via open flued gas space heaters posed a serious risk to people, especially in situations where there was little ventilation.

Ms Hughson said the decision to ban the sale and supply of heaters was an important step, however those already using these appliances needed to ensure they remained safe.

“Energy efficiency is important both for the environment and for household budgets. However, open flued gas space heaters were never designed to operate safely without ventilation,” Ms Hughson said.

“If you live in a renovated or weather sealed house with an open flued gas space heater, please get a qualified gasfitter to ensure carbon monoxide.”

Carbon monoxide poisoning symptoms can be similar to the flu, including headaches, tiredness and nausea. Seek medical advice if concerned, particularly if symptoms improve when outside.
