Installing a gas heater is regulated gasfitting work. A professional assessment should happen before a heater is purchased or installation begins. This checks whether the proposed appliance and location suit the home and whether the gas piping, flue, ventilation, electrical supply or ducting need attention.
A replacement is not always a direct swap. A new unit may have different capacity, clearance, flue, ventilation or connection requirements. An assessment can identify what needs to change and which appropriately qualified trades may be required.
Contact Melbourne Gas Plumber with details of your property, current heater and the area you want to heat. If you already have an appliance in mind, include its make and model to provide useful context for the enquiry.
A central gas heater warms air and distributes it to several rooms through ducts in the ceiling or beneath the floor. Some systems can be zoned so selected areas are heated. Installation suitability depends on factors such as available space, duct routes, the gas supply and any existing ductwork.
These heaters warm a particular room or living area and discharge combustion gases outside through a flue. Common forms include wall furnaces and some decorative gas log-effect heaters. Open-flued models use air from the room and require adequate fixed ventilation. Room-sealed models draw combustion air from outside, and Energy Safe Victoria recommends this design for gas space heating.
Our gas plumbers are licensed and insured. Gas heater work must be completed by a practitioner whose registration or licence covers the work being carried out.
A proper installation accounts for the gas connection, appliance location, manufacturer requirements, clearances, ventilation and any flue. These details need to be resolved before the heater is commissioned.
Domestic space and central heaters are generally Type A gas appliances. In Victoria, installing or replacing a Type A appliance requires a compliance certificate from a licensed plumber, regardless of the job value. Keep your copy with the property’s records.
Ducted gas heating may suit a home where several rooms need heating and suitable duct routes are available. A fixed flued space heater may be more relevant when the aim is to heat one defined area. Heater capacity, gas pipe sizing, location, ventilation, flue requirements, energy use and installation scope should all be considered before a unit is chosen.

Which option is right for your home? It depends on the size and layout of the property, how many rooms you want to heat, and the existing gas and heating setup.
Ducted gas heating can be a practical choice when you want to heat several rooms from one central system, provided there is suitable space for the heater and ductwork. A fixed flued gas space heater may be more suitable when you only need to heat a particular room or living area.
Before choosing a heater, it is important to consider factors such as heating capacity, gas supply, ventilation, flue requirements, available space and the overall installation scope.
In Victoria, gasfitting work includes the installation, replacement, testing and commissioning of gas appliances, consumer piping, flues and related fittings. Installing or altering a gas heater is not a DIY job. The work needs to be carried out by a practitioner with the appropriate gasfitting registration or licence, with a licensed plumber responsible for work that requires a compliance certificate.
The Building and Plumbing Commission states that only a licensed plumber can issue a compliance certificate. A registered plumber must work under the supervision of a licensed plumber when the work requires one. Homeowners can ask to see the practitioner’s photo ID and check their credentials on the Commission’s public register.
Professional installation also matters because gas heaters produce combustion gases. Carbon monoxide is colourless and odourless. A faulty appliance, blocked or unsuitable flue, or inadequate ventilation can allow carbon monoxide to build up or spill into a living area. An appropriately licensed gas fitter will apply the relevant manufacturer instructions and prescribed standards, account for ventilation and flue requirements, and complete the checks required for the installation.
Choosing a gas heater installer in Melbourne should start with the property’s suitability and the practitioner’s credentials. Contact Melbourne Gas Plumber to discuss the proposed heater, an existing unit you want to replace, or the information needed before an installation can be assessed.
