Gas > Safety & Preparedness > Maintaining Gas Appliances



Home gas appliances need to be regularly checked and maintained in accordance with manufacturers specifications. This is important to maintain proper function and safety.


Energy Safe Victoria (ESV) and the Victorian Building Authority (VBA) recommend that all gas water heaters, space heaters and central heaters be serviced at least every two years by a registered or licensed gasfitter to ensure they are working properly and to keep your family safe.


Having your gas appliance inspected and cleaned periodically by an authorised service technician will benefit performance, help ensure safe operation, minimise any potential down time and extend the life of your appliance. It is important that your gas appliances are only service by qualified technicians. In most cases, this means a licensed gas fitter or a factory technician. Never attempt to fix a gas appliance yourself or allow an unqualified person to attempt to fix it for you.


The gasfitter who services your appliance must use a CO analyser to test for carbon monoxide spillage.


Gas appliances need regular servicing as:

  • Burners in water heaters or space heaters can become blocked with dust or lint and then soot up the heat exchanger and flue passageways
  • Air filters, air ways and fans can become blocked by lint and dust, leading to overheating and burner problems
  • Safety controls can wear out and fail


Always follow the manufacturer's service plan and keep a record of the date of service.


Natural gas has a distinct odour, and to help keep your family safe, it’s important to be familiar with the smell.


Gas safety depends on many things, including the gas user taking care.


Always get a certificate of compliance (COC) for any gas works or installation in your home.
