In Menai 2234, detached family homes dominate, and that means higher hot water demand for showers, washing and dishwashers. For a typical four‑person household, hot water can be 20–30% of total electricity use. Swapping an old electric hot water system for a modern heat pump hot water system or solar hot water system can cut that significantly, especially when paired with rooftop solar. Popular brands locally include Rheem heat pump hot water and Rheem solar hot water for reliable all‑rounders, Sanden heat pump systems for ultra‑efficient premium options, and Rinnai solar hot water for households wanting a robust solar hot water installation. These sit alongside options from Thermann and Solahart when people are comparing the best hot water system Australia can offer.
Typical annual bill savings in Menai look like this:
• 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 rooftop solar: $250–$500 per year
Over time, those savings help offset the hot water system price, whether you are looking at a heat pump hot water price, solar hot water price or a straightforward electric hot water installation. When systems are sized correctly for local demand, a good energy efficient hot water system quickly becomes one of the best returns on investment in the home.
