Choosing a gas heater for your Melbourne home is not as straightforward as picking a brand from a website. The right heater depends on the size of your home, how you use it, your budget and what type of heating best suits your property layout.
This guide covers the main types of gas heaters available in Melbourne, the brands our technicians see and service most frequently and, based on years of attending repairs and installations across the city, what actually makes a gas heater good for Melbourne conditions.
One important note before we begin: we are a gas fitting company, not a retailer. We do not receive commissions from any manufacturer. Our assessments are based on what we see in the field, which brands hold up, which models cause recurring problems and which systems actually suit Melbourne's winters.
Types of Gas Heaters Available in Melbourne
Before looking at brands, understand the types. Choosing the wrong type for your home is a bigger mistake than choosing the wrong brand within the right type.
Ducted Gas Heating Systems
A ducted system heats the entire home through a central unit in the roof space connected to vents in every room. One system, one thermostat, consistent warmth throughout the home.
Best for: Homes of three bedrooms or more, families who want whole-home heating, homeowners upgrading from multiple individual heaters.
Not ideal for: Small apartments, properties where roof access for duct installation is not feasible.
Wall Furnaces (Flued)
Wall-mounted flued gas heaters that heat a single room or open-plan area. They vent combustion gases externally through a flue and are significantly safer than unflued alternatives.
Best for: Supplementary heating in specific rooms, smaller homes, older properties where ducted installation is not practical.
Not ideal for: Whole-home heating across multiple rooms (multiple units required).
Gas Space Heaters (Freestanding)
Freestanding portable heaters connected to the gas supply via a flexible hose. Can be moved between rooms.
Best for: Renters, temporary heating solutions, supplementary heating.
Important note: Unflued portable gas heaters should not be used in small rooms or bedrooms. CO and moisture accumulation is a genuine risk.
Gas Log Fires and Fireplaces
Gas fireplaces combine the aesthetic of a real fire with gas convenience. Available as inbuilt (installed into a fireplace opening) and freestanding models.
Best for: Feature heating in living areas, homeowners who value ambience as well as warmth.
The Best Ducted Gas Heating Brands for Melbourne
Braemar: Our Top Pick for Melbourne
Braemar is Victoria's most widely installed ducted gas heating brand for good reason. Braemar systems are manufactured by Seeley International, an Australian company, and are specifically engineered for Australian conditions including Melbourne's cold, damp winters.
What we see in the field: Braemar systems installed 15 to 20 years ago are still running in Melbourne homes with regular servicing. Parts availability through Seeley International is excellent. Fault rates on regularly serviced Braemar systems are low.
The Braemar Dominator series is the benchmark for ducted gas heating in Victoria. If you are installing a new ducted system in a Melbourne home, Braemar Dominator is the system we most frequently recommend.
Star rating: Available in 5 to 6 star
Output range: 60 MJ/h to 175 MJ/h
Best for: Standard to large Melbourne homes
Brivis: Solid Reliability and Good Parts Support
Brivis is another Seeley International brand and shares similar engineering values with Braemar. Brivis systems are widely installed across Melbourne and parts availability is good. The Brivis Star Pro and Networker zone control systems are popular for their room-by-room temperature management capability.
What we see in the field: Brivis systems are reliable workhorses. The most common fault we see is capacitor failure on fan motors, a straightforward and inexpensive repair. Controllers in the Star Pro and Networker range are well-supported.
Rinnai: Strong Brand, Wide Service Network
Rinnai is Australia's best-known gas appliance brand. Their ducted heating range is solid and well-supported nationally. Rinnai's advantage is the breadth of their service network and parts availability across Australia.
What we see in the field: Rinnai ducted systems are reliable and easy to service. Zone controller faults are the most common issue we attend. Parts are widely available.
Bonaire: Established and Serviceable
Bonaire has a significant installed base across Melbourne, particularly in homes built during the 1990s and 2000s. Bonaire systems are serviceable and parts are available. If you have an existing Bonaire system, like-for-like replacement is straightforward.
The Best Gas Wall Furnace Brands for Melbourne
Rinnai: The Clear Market Leader
Rinnai dominates the wall furnace market in Melbourne and for good reason. The Rinnai Energysaver series has been one of the most reliable gas heaters sold in Australia for decades. High efficiency ratings, excellent parts support and a broad range of output sizes make Rinnai the default recommendation for a new wall furnace installation.
What we see in the field: Rinnai Energysaver heaters installed in the 1990s and 2000s are still in service across Melbourne with regular servicing. The most common fault is thermocouple replacement, a $150 to $210 repair that we carry parts for on every van.
Popular models: Rinnai Energysaver 556FT, 309FT, Avenger 25 and 35
Braemar: For Homes That Want the Brand Alignment
Braemar also produces wall furnace models. If you are installing both a ducted system and supplementary wall heaters and want brand consistency, Braemar is a good choice.
The Best Continuous Flow Hot Water Brands
While hot water systems are not heating appliances in the traditional sense, they are the second most common gas appliance we install and service. For completeness:
Rinnai Infinity: The market standard. Reliable, efficient and the most widely serviced continuous flow brand in Melbourne. The Infinity 26 is the most commonly installed residential unit.
Bosch: Premium German engineering. Popular in higher-end renovations. Excellent reliability record.
Rheem: Australia's most recognised hot water brand. Solid reliability and broad service network.
Key Factors to Consider When Choosing a Gas Heater for Melbourne
Correct sizing is the most important decision
An undersized heater will run constantly and still fail to heat the space adequately. An oversized heater will short-cycle and run inefficiently. Getting the output right for your home's size, insulation and ceiling height is more important than which brand you choose.
For ducted systems, never choose a system based on floor area alone. Ceiling height, insulation quality, glazing and the number of zones all affect the correct system size. This is why we carry out a free in-home assessment for every new ducted heating installation.
Star rating matters for running costs
A 6-star ducted system is approximately 20 to 25 per cent more efficient than a 4-star system of the same output. The upfront cost premium is typically recovered through energy savings within 2 to 3 years of regular Melbourne winter use.
For a Melbourne home spending $2,000 per year on gas heating, this represents a genuine saving of $400 to $500 annually. Choosing a higher-rated system is almost always financially sound for Melbourne homes.
Flued vs unflued
We strongly recommend flued heaters for all permanent installations. Unflued heaters release combustion byproducts directly into the room, including moisture, CO2 and trace CO. In well-sealed modern homes, this is a concern. For permanent room heating, always choose a flued model.
Zone control for larger homes
Modern ducted systems with zone control allow different areas of the home to be heated independently. Heating only the areas you are using can reduce gas consumption by 30 to 50 per cent compared to heating the entire home equally. For larger Melbourne homes, zone control is well worth the additional investment.
Brand parts support
One factor often overlooked when buying a gas heater is parts availability for the long term. A system from a brand with strong Australian parts support will be serviceable for its full 15 to 20 year lifespan. A less established brand may face parts supply challenges within 10 years.
Braemar, Brivis and Rinnai all have strong Australian parts networks. These are the brands we most confidently recommend for long-term Melbourne use.
