Sale of unsafe open flued gas space heaters prohibited

As of the 10 October 2022, the sale of open-flued gas space heaters that don’t have safety shutdown features has been prohibited. This includes the sale of new and second hand heaters.

The prohibition took effect on 10 October 2022.

What are the safety concerns?

It’s possible for open-flued gas space heaters to spill carbon monoxide in a negative pressure environment.

Negative pressure can occur when a home isn’t ventilated enough and an exhaust fan is on. For example, when operating a:

  • kitchen range hood
  • bathroom fan
  • roof-mounted exhaust fan.

This can cause external openings such as flues to draw air into the home. That means dangerous gasses such as carbon monoxide can be drawn into living spaces.

A safe open-flued gas space heater will shut down if this occurs.

For more information, view the information on negative pressure.

What is Carbon Monoxide?

Carbon monoxide (CO) is a colourless, odourless, poisonous gas which may be produced by faulty, poorly maintained or misused gas appliances.

CO interferes with the blood’s ability to carry oxygen, which can cause serious health issues and can even be fatal.

You may not know you have been exposed to potentially fatal levels of carbon monoxide until the symptoms of poisoning become severe.

Exposure to low levels of CO may result in a person experiencing headaches, weakness, fatigue and nausea but at higher levels, symptoms could include severe headache, dizziness, rapid or irregular heartbeat, vomiting, seizures and collapse. In extreme cases this can lead to coma and death.

Maintenance and correct ventilation will ensure gas appliances produce minimal CO.
