Heating your home with gas

Gas heating is generally a safe and efficient way to heat our homes. However, if not maintained properly they can be deadly.

All gas heaters have the potential to spill or leak deadly carbon monoxide (CO). This includes central heating units, space heaters, wall furnaces and decorative log fires.

ESV and the Victorian Building Authority (VBA) recommend that all gas water heaters, space heaters and central heaters are serviced at least every two years by a qualfied gasfitter. Find your local registered gasfitter by searching online or via the VBA’s website

CO poisoning

Carbon monoxide (CO) is a colourless, odourless and tasteless gas resulting from the incomplete combustion of hydrocarbon fuels. Carbon monoxide spillage can be lethal. It can cause death or chronic illness.

Recent incidents of CO poisoning from open-flued gas heaters has caused ESV to step up our safety warnings to Victorian households.

In the past decade, nine Victorians have died from CO poisoning, including brothers Chase and Tyler Robinson who died in their Mooroopna home in 2010.

Carbon monoxide poisoning can happen in any home or building with gas heating appliances, including newer ones.

Dirty, old and unserviced heaters operating in a sealed environment will increase the risk of CO spillage and smaller, poorly ventilated dwellings are at a greater risk.

Signs and symptoms of CO poisoning

The signs and symptoms of CO poisoning are non-specific and commonly misdiagnosed as the flu. Symptoms such as headaches, dizziness and nausea are common.

Read more on symptoms, diagnosis and the risks associated with CO poisoning via the Department of Health and Human Services.

Open flued heaters

Recent investigations into incidents involving open flued gas heaters have highlighted how vulnerable and sensitive these gas heaters can be in the environment they are operating in. In particular, ESV believes that open-flued technology is incompatible with sealed and energy efficient homes.

Open flued heaters draw air from the room to feed the fire. Inadequate ventilation and use of exhaust fans can draw carbon monoxide (and other exhaust gases) back into the room in certain circumstances.

To identify whether your gas heater is open flued, you must contact the manufacturer or a qualified gasfitter.

Find more information and tips on the safe use of common flues and ventilation, here.

Chimneys

While brick chimneys are designed to safely remove combustion products from the home, they can deteriorate over time. Any holes in the mortar or brick work may stop the chimney drawing properly. If the fault is significant, it may create back pressure and push toxic carbon monoxide into living areas.

Arrange a gas heater service today with your local plumber/ gasfitter. Before you book, ask the gasfitter if they have the right equipment to test for carbon monoxide leakage.

Certified open flue space heaters

Energy Safe Victoria has compiled a list of certified open flue space heaters based on information provided by the five certification bodies.

At this time, the Vulcan/Pyrox Heritage is the only model of heater for which a safety alert has been issued.

However, anyone who has any one of the models of heater on this list should have it serviced and tested for carbon monoxide (CO) spillage at least every two years.

There are several ways to determine whether your heater is open flue:

  • Contact the manufacturer
  • Ask a qualified gasfitter during regular servicing.

Safe heating tips with gas

  • Get your heater serviced once every two years: this will ensure your heater runs safely and efficiently. Ask for a qualified gasfitter.
  • Only use a qualified gasfitter: ask your gasfitter for a Compliance Certificate on completion of any installation work.
  • Don’t leave the heater on overnight: avoid using your gas heater for extended periods or when not required.
  • Don’t operate exhaust fans at the same time as the heater: your rangehood, toilet or bathroom fan can create a ‘negative pressure’ effect where carbon monoxide that should escape out the flue is drawn into living areas.
  • Consider back-up measures such as a carbon monoxide alarm: carbon monoxide alarms can be a useful back-up precaution, but should not be considered a substitute for the proper installation and maintenance of gas heating appliances. See more on carbon monoxide alarms below.
  • Ensure you have adequate ventilation: while it is not necessary to have windows and doors wide open on a cold day, ventilation is important to ensure your heater operates correctly.
  • Consider replacing old appliances: avoid buying second-hand appliances. Find more on Buying safe gas appliances.

Safety alert – Heritage gas space heater

ESV has issued a safety alert on Vulcan Heritage / Pyrox Heritage gas space heaters.

All Victorians with a Vulcan Heritage or a Pyrox Heritage gas space heater in their home need to get them checked by a qualified gasfitter immediately.

For people living in DHHS housing

The Department of Health and Human Services (DHHS) has a program in place to have all Vulcan Heritage gas space heaters or Pyrox Heritage gas space heater in their properties tested.

Phone DHHS on 1800 148 426 for more information.

For private homes

Contact the manufacturer – Climate Technologies – to arrange for a CO spillage test of the heater and the installation environment by a qualified gasfitter (to be appointed by Climate Technologies).

Phone Climate Technologies on (03) 8795 2462 for more information.

Carbon monoxide alarms

If you are considering purchasing one or more carbon monoxide alarms, remember to:

  • select alarms that meet US or EU carbon monoxide standards, including recommendations for use and installation. To identify these alarms, either the packaging or the alarm will indicate that it complies with one of the following standards:
    • UL2034 (US) or
    • EN50291 (EU)
  • select alarms that provide visual and audible alarms indicating when the electrochemical sensor or battery has expired. While these alarms may provide an indication of the presence of carbon monoxide, their effectiveness is limited to the location where they are installed, as carbon monoxide levels elsewhere in the room may vary.

Similarly:

  • if you purchase a hard-wired alarm, it must be installed by a licensed electrician
  • if you are installing a battery operated CO alarm, ensure you follow the manufacturer’s installation instructions which should detail where the alarm should be located.

Prohibited installations

Certain gas appliances have been prohibited within the home, including:

  • flueless space heater operating on Natural Gas where combustible products are released less than 2.5m above floor level.

Campaign: Carbon Monoxide – A Silent Killer

To keep Victorians safe from carbon monoxide poisoning, ESV runs an annual campaign titled Carbon Monoxide – A Silent Killer.’

After losing her two sons from carbon monoxide poisoning in 2010, Vanessa Robinson has worked closely with ESV to continue raising awareness of the dangers around the silent killer to help prevent such tragedy happening to other Victorian families. You can find more information on her work through The Chase and Tyler Foundation.
