Gas heater installations across Adelaide
Wall-mounted gas heaters
For single rooms or open-plan living. Brands we install: Braemar (Vector wall), Brivis (Buffalo wall), Vulcan (Heritage, Merlin), Regency. Typical install takes 4-6 hours including gas line and flue work. Expect $1,800-$3,500 supplied and installed depending on brand and complexity.
Space heaters (freestanding flued)
Console units and freestanding radiants. Rinnai Avenger, Rinnai Energysaver, Braemar Tempra, Regency Panorama. Typical install 3-4 hours. Usually $1,600-$3,200 supplied and installed.
Ducted gas heating (new system)
Whole-home solutions. Typical for Adelaide: Braemar Vector, Brivis Buffalo, Bonaire VSL. Full system install takes 1-2 days depending on roof access and zone complexity. Typical cost $5,500-$12,000 supplied and installed including ducts, zones, and controller. We size every system to your home's heat load — not to a sales target.
Replacement (like-for-like)
Swapping an old unit for a new one. Faster and cheaper than a brand-new install if the gas line and flue are already in place. Typical cost $1,400-$4,500 all up.
Gas connection work
Extending gas line to a new heater location. Licensed gas fitter work — illegal for non-licensed people to do. Typical cost $450-$1,200 depending on run length and pipe type.
Flue work
New flues, flue extensions, roof penetrations for wall-mounted units. Often the thing that pushes an install timeline — we quote realistic, not optimistic.
Why most Adelaide gas heaters are the wrong size
Over 60% of the ducted systems we service in Adelaide are undersized for the home they're in. You feel it as: system runs constantly, never quite warms the house, gas bill is huge, back rooms stay cold.
The reason: most sales reps size off floor area alone — "150 square metres = 25 kW system." That ignores:
- Insulation (or lack of it — most Adelaide homes pre-2000 have minimal ceiling insulation)
- Window area and whether they're single or double glazed
- Ceiling height (2.4m standard vs 3m+ in Victorian homes)
- Number of outside walls (corner rooms are coldest)
- Adelaide microclimate — foothills suburbs are 3-5°C colder
- Duct losses in the roof space (real number: 15-30% depending on insulation)
We do a proper heat-load calculation before we quote any system. It takes us 30 minutes on site and means you don't have a system fighting your house for the next 15 years.
