Heat Pump vs Gas Hot Water in Brisbane: 2026 Verdict
13 March 2026 7 min read
With federal rebates dropping heat pump prices and gas connection fees creeping up, the maths in Brisbane has shifted decisively. Here's the honest comparison for a 4-person household.
Upfront Cost (installed)
Gas continuous flow: $2,400–$3,400. Heat pump: $3,600–$4,900 after Federal STC rebate + Queensland incentives.
Running Cost / Year
Gas: ~$430. Heat pump: ~$180 (or under $100 if paired with solar PV). Over 10 years the heat pump saves ~$2,500.
Lifespan
Gas continuous: 12–15 years. Heat pump: 10–15 years with maintenance.
Verdict for Brisbane
If you have solar PV or space outside a bedroom wall, heat pump wins. If you're gas-connected already and space is tight, continuous flow still holds up.
Frequently Asked Questions
Are heat pumps noisy?
Modern units run at 45–55dB — quieter than a fridge. Just don't mount them under a bedroom window.
