New gas heater installation across Greater Hobart.

The seven-stage install.

1. Site assessment and quote. Room volume, ventilation, existing gas service capacity, flue path options, appliance shortlist. Written quote within 48 hours.
2. Appliance selection. Match heater output (typically 15–25 MJ/h for a Hobart living room) and flue type (open-flued, fan-flued, balanced-flue) to room size and house ventilation profile.
3. Gas service capacity check. Verify the meter and service line have capacity for the new appliance load. Upsize service if needed (additional TasGas application).
4. Flue install. Flue path constructed to AS/NZS 5601.1 clearances. Internal liner, external terminal, anti-downdraft cowl as appropriate. Roof flashing or wall penetration weatherproofed.
5. Appliance install. Heater positioned, gas connection made with leak-tested fittings, electrical supply if required, controls commissioned.
6. Commissioning & safety test. Gas pressure test, ambient CO test, flue draft test, full function test including all safety shut-offs.
7. Certificate of Compliance & handover. Certificate of Compliance lodged with TasNetworks Gas, customer handover pack including manufacturer manual, service due date, warranty registration.

Choosing the right flue type.

Open-flued. Traditional Type-A space heaters in most pre-2000 installations. Combustion air drawn from the room, flue gases discharged through a vertical flue to the roof. Cheapest to install where an existing flue path exists. Highest dependency on adequate room ventilation. Not always appropriate in modern tight-sealed homes — we assess room ventilation carefully before recommending open-flued in a recent retrofit.

Fan-flued. Powered exhaust fan in the flue assembly — can vent horizontally through a wall, doesn’t rely on natural thermal draft, much more tolerant of negative pressure from rangehoods and exhaust fans. Typical $200–$400 premium over open-flued. Our default recommendation for any tight-sealed home or any installation without an existing vertical flue path.

Balanced-flue (room-sealed). Combustion air drawn from outside through a concentric flue, combustion products discharged through the same flue. Completely sealed from the room — zero spillage risk regardless of room ventilation. Most expensive option ($400–$700 premium) but the right answer for new-build sealed envelopes, bedrooms, or any room where spillage would be unacceptable.

Pricing band breakdown.

• Like-for-like swap into existing flue path (open-flued heater into existing chimney with intact liner): $1,200–$1,900 supply-and-install.
• New install with new horizontal fan-flue through external wall: $1,500–$2,300.
• New install with new vertical balanced-flue through roof: $1,800–$2,800.
• In-built or hearth-mounted gas log fire (e.g. Real Flame Pyromaster): $2,200–$4,500 supply-and-install.
• Ducted gas central heating system (roof-mounted heat exchanger, full ductwork): $6,500–$14,000 supply-and-install depending on house size.
• Heritage-overlay precinct installs (Battery Point, parts of Sandy Bay): add $300–$800 for heritage advisor sign-off and discreet terminal options.

Tasmanian Gas Safety Act 2019 — the paperwork.

Every new gas installation in Tasmania must be carried out by a licensed gas-work practitioner and notified to the gas safety inspector via a Certificate of Compliance. We lodge the certificate electronically with TasNetworks Gas at install completion. The certificate is what your insurer and any future conveyancer will request — without it, the appliance is non-compliant on paper. We provide:

• Certificate of Compliance lodged with TasNetworks Gas
• Appliance installation and commissioning record
• Gas pressure and CO test results at handover
• Manufacturer warranty registration
• Customer handover pack with manual and first-service due date
• Photo record of install (flue path, clearances, terminal location)

Builder partnerships across Kingston & Glenorchy growth corridors.

We work with several Tasmanian residential builders on standing-order new-install programs. Per-build pricing locked, scheduling integrated with the builder’s handover milestones, Certificates of Compliance lodged before handover, customer handover pack including the first-service date. Talk to us if you’re building 5+ homes per year in Greater Hobart and need a reliable gas-fitter partner.
