Bonnie Doon and the wider 4873 area enjoy strong sunshine, with average solar exposure of about 18.8 MJ/m² per day – roughly 5.2 kWh/m²/day. That makes a solar hot water heating system or heat pump hot water installation a natural fit, especially for households juggling mortgages of around $1,430 a month or rent of about $260 a week. Upgrading from older gas or resistive electric to an efficient hot water upgrade can carve a big chunk off annual bills, particularly for families and retirees who are home more during the day.
Around the postcode, most dwellings are separate houses, and many already have rooftop solar, so using that free sunshine for a solar hot water system or to power a heat pump hot water system is the logical next step. Brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and Thermann are common choices for Bonnie Doon homeowners wanting the best hot water system Australia can offer for long-term reliability and low running costs. For some households, a well-sized electric hot water installation timed to run on solar can also be a smart move, especially when comparing solar hot water vs electric hot water.
Typical annual bill savings for Bonnie Doon homes can look like:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water: $300–$700 per year • Gas to solar hot water system: $250–$600 per year • Old electric to modern electric hot water system with solar: $200–$500 per year
Over time, these savings easily outweigh the hot water system price, especially when you factor in rebates and rising energy costs.
