Gas Heating

Heat your home efficiently with gas ducted systems and external gas heaters designed for Australian conditions. This page explains the core options, how to choose capacity, and what to check before you buy. You can compare compact classics with high performance series, then add a compatible controller and zoning to finish the job.

Renovation Kingdom stocks trusted brands with clear specs and fast delivery. The range includes internal gas ducted heaters for ceiling or underfloor installs, plus external gas heaters that free up indoor space and simplify flueing. If you are upgrading an ageing unit or fitting out a renovation, you will find sizes for small homes through to larger multi-zone layouts.

Why choose gas ducted heating

Gas heating delivers quick warm-up and even distribution through the home. A central unit draws air across a heat exchanger and supplies warm air via ducts to ceiling or floor vents. You get stable temperatures, good airflow, and control from a single interface. For existing homes with ducts in place, a straight swap can modernise efficiency and add zoning without major changes to the layout.

Internal vs external units

Internal gas ducted heaters sit in a roof space or underfloor cavity. They keep the unit protected and close to ducts, which can reduce installation time in some homes. External gas heaters mount outside and connect through short duct runs and a weatherproof return. They are ideal where roof space is tight or access is difficult. External placement can also reduce indoor service noise and simplify condensate and flue requirements. Your installer will advise which format suits your site, gas supply, and duct routing.

Spotlight on the range

The Brivis line covers compact classics through to high output series with advanced control. The Brivis Classic Compact Gas Ducted Heating is a practical choice for smaller homes and straight replacements where budget and footprint matter. The Brivis Wombat Classic Gas Ducted Heating increases output for family homes and fits well where a sturdy, proven platform is preferred. For external locations, the Brivis Buffalo Compact External Gas Heater offers a neat outdoor package that keeps plant out of the roof space.

For higher performance and modern control options, the Starpro family gives you a choice of formats and capacities. The Brivis Starpro Series 4 Internal Gas Ducted Heating and Starpro Series 4 Non-Condensing External Gas Heater cover common Australian homes with reliable heat output and flexible install options. If you want more headroom for larger zones or colder regions, the Brivis Starpro Series 5 Internal Gas Ducted Heating and Starpro Series 5 Non-Condensing External Gas Heater deliver stronger airflow and steady temperature control. At the top of the page, the Brivis Starpro Series 6 Internal Gas Ducted Heating and Starpro Series 6 Non-Condensing External Gas Heater suit bigger floor plans and multi-area zoning where several rooms run at once.

Each series is designed to match typical duct sizes, return air placements, and standard ceiling or floor outlets. Product pages include footprint, clearance, and connection details so you can confirm fit before you order.

Capacity, airflow, and zoning

Correct sizing avoids short cycling and cold rooms at the edges of the house. Think about floor area, ceiling height, insulation, window size, and your local winter temperatures. For small homes or units, a compact classic can be enough. Mid-sized family homes often align with Series 4 or Series 5. Larger layouts with several living areas and long duct runs benefit from Series 6. If you plan to add zones, consider the highest number of rooms that will run at the same time. A unit sized for two living areas and two bedrooms in the evening will feel more comfortable than an undersized unit pushed to its limit.

Zoning lets you group rooms and heat only the areas in use. This reduces running time and gives you tighter control. Many Starpro units pair with compatible zone controllers, so you can set living areas warmer in the evening and let bedrooms sit lower. Good zoning starts with clear room groupings and dampers that are easy to service later.

Installation notes

All gas heating work must be carried out by licensed trades. Decide early where the unit will sit and how ducts will reach each zone. Internal installs require safe access panels, compliant clearances, a proper return air path, and provision for service. External installs need a solid base, weather protection, and neat penetrations for supply and return. Your installer will check gas supply pressure and pipe sizing, confirm flue and condensate requirements where relevant, and test airflow at the outlets. A clean return filter and well-sealed ducts support quiet, efficient operation.

Controls and comfort

A simple, readable controller makes day-to-day use easier. Many systems support basic set-and-forget schedules along with quick manual overrides. Pairing a modern gas heater with a compatible controller can improve temperature stability and avoid overshooting. If you have children or guests, a lockable set point avoids constant fiddling and keeps comfort consistent.

Running costs and maintenance

Gas ducted heating can deliver steady comfort with predictable bills when sized and maintained well. Seal gaps around doors and windows, close off unused rooms if you are not running a zone there, and set a sensible temperature rather than chasing rapid swings. Seasonal checks pick up small air leaks and blocked filters. Clear any debris around external units and keep return air grills free of dust. A service schedule that includes burner checks, fan assessments, and control testing will keep performance on track.

Choosing in three steps

Start with the format that suits your site. Pick an internal gas ducted heater where roof or underfloor space works and you want a protected install. Pick an external gas heater where access is better outside or you are short on internal space. Next, match capacity and airflow to floor area and the number of rooms you heat at the same time. Finally, add zoning and a compatible controller so you use less energy and improve comfort.

Upgrade paths and replacements

Replacing an ageing gas heater with a like-for-like format can reduce install time and keep ducts in place. If you are moving from an old external unit to a modern external Starpro, you keep plant outside and often improve noise and service access. If you plan a renovation that adds rooms, upsizing to a Series 5 or Series 6 now can save you a second swap later. For straight swaps, check return size, supply plenum dimensions, gas connection location, and controller cabling early to avoid delays.
