Grassdale’s strong solar exposure helps. The local weather station records mean daily solar energy of about 15.3 MJ/m², which is roughly 4.25 kWh/m² per day across the year. That level of sunlight supports both a solar hot water heating system and high‑efficiency heat pump hot water, delivering solid annual hot water energy savings compared with older systems. For many families on a median household income of around $1,442 per week, those savings free up cash for other priorities, while cutting emissions at the same time.
Across the 3302 postcode, households are gradually moving away from older gas and resistive electric hot water towards more efficient hot water systems. With a mix of three‑ and four‑bedroom homes, daily demand is moderate to high, so hot water energy use can be a big slice of the power bill. That is why more locals are comparing heat pump vs solar hot water and even solar hot water vs electric hot water to see what works best with their roof space, budget and lifestyle.
Typical annual bill savings in rural Victoria for Grassdale‑type homes look like this:
• Old electric to heat pump hot water installation: $400–$900 per year • Gas to heat pump hot water installation: $300–$700 per year • Gas to solar hot water installation: $250–$600 per year • Old electric to modern electric hot water installation with solar: $250–$500 per year

Hot Water Rebates, Tariffs & Savings
Across Grassdale and regional VIC, more households are replacing old gas or ageing electric units with efficient options like heat pump hot water, new electric hot water system models and roof‑mounted solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) help reduce the upfront solar hot water price / cost and heat pump hot water price / cost, effectively acting as a solar hot water rebate or heat pump hot water rebate at the point of sale. Victoria also offers state programs that can operate like a hot water rebate vic, including some electric hot water system rebate support when moving away from gas.
