Wandong’s solar exposure is a real asset. The nearby Kilmore Gap weather station records mean daily solar exposure of about 15.5 MJ/m², or roughly 4.3 kWh of sunshine per square metre per day across the year. That strong sunlight helps a solar hot water heating system pre‑heat your water and boosts the performance of a good heat pump hot water system.

Across 3758, there have been 105 efficient hot water installations recorded, combining heat pump hot water installation and solar hot water installation. Installations ramped up between 2008 and 2014, peaking around 2011 and 2014, and there is still steady interest through to 2024. That growth shows more Wandong residents are comparing heat pump vs solar hot water, looking at solar hot water vs electric hot water, and choosing systems that suit their roof space, budget and lifestyle. Brands like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium options such as Sanden heat pump units all have a place in the local market, from family homes to tradie sheds and small businesses.
For a typical Wandong home, hot water can be one of the biggest energy users after heating and cooling. Swapping an old storage electric hot water system for a modern heat pump or solar hot water heating system can make a big dent in running costs. As a guide, annual bill savings might look like:
• Old electric to quality heat pump: around $400–$800 per year • Gas storage to heat pump: around $300–$600 per year • Gas storage to solar hot water system: around $250–$550 per year • Old electric to modern electric hot water system with rooftop solar: around $300–$700 per year
Choosing between the best hot water system Australia can offer and the best heat pump hot water system for your place comes down to your roof, budget and how you use hot water. Many Wandong homes already have solar PV, so pairing a heat pump or efficient electric hot water installation with daytime solar can give you very low running costs. Others prefer a roof‑mounted chromagen solar hot water or similar system with a ground tank. If your existing solar hot water tank replacement is due, it can be a good time to compare heat pump hot water price / cost and solar hot water price / cost side by side.
Hot water repair and maintenance also matter. A simple hot water repair on an older unit might get you by, but if the hot water system price / cost of ongoing fixes keeps creeping up, it may be smarter to invest in a new energy efficient hot water system. Local plumbers and hot water VIC specialists can help with solar hot water repair, hot water installation and electric hot water system rebate advice, and make sure your electric hot water vs gas hot water decision stacks up in real numbers.
