When you compare options such as heat pump vs solar hot water or solar hot water vs electric hot water, it comes down to roof space, budget, and whether you already have solar PV. A solar hot water installation or heat pump hot water installation can dramatically cut running costs, while a well‑sized electric hot water installation paired with rooftop solar can also work well. For many homes, moving to all‑electric hot water is a smart way to get off gas and future‑proof the property.
Average annual savings in Oakleigh South are substantial. Typical ranges for a standard family home include:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water system with solar: $250–$500 per year
Over time, those savings easily outweigh the hot water system price or cost of an upgrade. Even premium options like a Sanden heat pump, or a quality chromagen solar hot water or Rheem or Rinnai system, can have payback periods shortened when paired with solar and smart controls.
