Wondalga’s climate helps. Nearby Adelong records an average annual solar exposure of about 17.5 MJ/m² per day – roughly 4.9 kWh/m²/day – which is excellent for both a solar hot water heating system and high‑efficiency heat pump hot water. That strong sunlight means a well‑designed solar hot water installation or heat pump hot water installation can cover most of your hot water energy needs across the year, especially if you already have rooftop solar.
In a postcode where 299 homes are owned outright and 182 are mortgaged, many owners are looking at long‑term ways to cut running costs. Hot water use is often the second‑biggest chunk of household energy, so replacing an old gas or electric unit can deliver meaningful savings. Locals are comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to find the most efficient hot water system for their situation and budget.
For typical Wondalga homes with three or four bedrooms, hot water demand is steady year‑round. Efficient systems like Rheem heat pump hot water, Sanden heat pump units and solar brands such as Solahart or Rinnai solar hot water are becoming more common, helped by competitive hot water system price points once rebates are applied. Many households are also upgrading ageing solar hot water tanks, with solar hot water tank replacement and solar hot water repair work keeping older systems performing well.
Average annual bill savings for Wondalga homes can 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 installation with solar: $250–$500 per year
Since 2002, there have been 46 efficient hot water installations (heat pump and solar hot water) recorded in the 2729 area, with noticeable peaks between 2008 and 2011 when annual installs reached up to eight systems a year. More recent years show steady, if slower, activity, with new systems going in during 2020, 2023 and 2025.
