All gas heaters can spill carbon monoxide (CO) – a gas you can’t see or smell that can make you seriously sick or kill you.

To be sure your gas heater is safe, you should:

  • have it serviced at least once every two years, by a qualified gasfitter
  • check for safety advice – some heaters need fresh air flow to operate safely.

Are you a tenant, rental provider or real estate agent?

Victoria’s new rental laws came into effect on 29 March 2021.

Consumer Affairs VictoriaExternal Link (CAV) is the agency responsible for these regulations. The CAV website provides detailed summaries and guides on the full range of changes included in the new renting regulationsExternal Link .

Under the new laws rental providers (previously referred to as landlords) have certain responsibilities for gas and electrical safety.

The rental provider must ensure a gas safety check of all gas installations and fittings on the premises is conducted every two years by a licensed or registered gasfitter who is endorsed in the specialised class of Type A gas appliances servicing work (Gas Serving Type A on the Plumbers Identity Card).

Use your gas heater safely

  • Check if a safety alert has been issued for your gas heater.
  • Don’t use kitchen rangehoods or exhaust fans at the same time as your heater. This can create what is known as a negative pressure environment, where carbon monoxide is drawn into living spaces.
  • Don’t leave your gas heater on overnight, or for extensive periods.
  • Install a carbon monoxide alarm as a back-up measure.
  • If your heater is very old, consider replacing it.
  • Never bring portable outdoor gas appliances indoors.

Is carbon monoxide (CO) making you sick?

CO building up inside your home can make you sick for a short time, have long-term health effects or even kill you and your family quickly.

Some of the symptoms are similar to cold symptoms, common in winter. This can make it difficult for a doctor to diagnose that you are suffering from carbon monoxide poisoning.

If you notice any of the following symptoms, they could be caused by carbon monoxide leaking from your heater.

  • Dizziness
  • Feeling sick or nauseous
  • Headaches
  • People and/or pets getting sick at the same time
  • Feeling unwell only when you’re at home.

Act quickly if you think your heater could be making people sick

  • Call Nurse-on-CallExternal Link , see a doctor or dial 000 in an emergency
  • Leave the house immediately and get into the fresh air
  • Turn off all gas appliances straight away, open windows and doors to let fresh air into the house
  • Do not use your heater until you’ve had it checked by a qualified gasfitter.

Finding a licensed gasfitter

Gasfitters have different types of licences depending on the work they are qualified to do. All registered and licensed plumbers are issued with a Photo ID card that lists the type of work they can do.

When searching for a gasfitter, you will need to check their qualifications and areas of expertise. Contact them and ask if they are licensed for the service required. When they attend the site, ask to check their licence card and the registered classes listed on the back of the card.

Type A gasfitters

There are two different types of gas appliances – Type A and Type B appliances.

Type A appliances include domestic and light commercial type appliances such cookers, space heaters, central heaters, water heaters, catering equipment and leisure appliances.
