Summary
A detailed field comparison emerged regarding heat pump (air-energy) water heaters versus continuous flow gas systems for secondary dwellings. Heat pumps attract significant government green energy rebates, bringing capital costs down to roughly 800 AUD. However, due to longer recovery times and large tank space requirements, multiple simultaneous taps often exhaust supply, causing some landlords to switch back to gas. Continuous gas units, ranging from 1,800 AUD to 2,500 AUD installed, deliver instant hot water, boast a 10-to-20-year lifespan, and occupy minimal space, yielding higher tenant satisfaction.
Key Points
Why it matters: Choosing appliances for Granny Flats or secondary dwellings fundamentally sets long-term maintenance overheads. Distinguishing between heavily promoted government energy rebates and real-world tenant hot water satisfaction ensures steady cash flow and lowers plumbing emergency frequencies.
