Drouin’s climate is well suited to efficient hot water. The town enjoys mean daily solar exposure of about 14.5 MJ/m², which is roughly 4 kWh per square metre per day. That level of sunshine helps a solar hot water heating system perform reliably and supports a heat pump hot water system, which effectively “moves” heat from the air rather than creating it from scratch. When you upgrade from an older gas or off‑peak electric unit to an energy efficient hot water system, it is common to see annual hot water energy savings of hundreds of dollars for a typical family home.
Around postcode 3818, demand for hot water installation has been growing as more people add rooftop solar and look for the most efficient hot water system to match it. Families and downsizers alike are comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to see what fits their roof space, budget and lifestyle. Brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a solar hot water installation, while Sanden heat pump and Rheem heat pump hot water units are popular for households chasing the best heat pump hot water system and low running costs.
For a typical Drouin home, the right system size depends on how many people are in the house, how many bathrooms you have and whether you already have solar. Many locals are switching from gas to all‑electric, pairing a heat pump hot water installation or electric hot water installation with solar panels to keep bills down. To give you a feel for potential savings, here are some realistic annual bill reductions:
• Old electric to heat pump hot water system: save roughly $400–$800 per year • Gas to heat pump hot water system: save around $250–$600 per year • Gas to solar hot water system: save roughly $200–$500 per year • Old electric to modern electric hot water with solar: save around $300–$700 per year
In Drouin, there have already been 2,342 efficient hot water systems installed, covering both heat pump and solar hot water installations.

More recently, installations climbed again, with strong growth through 2017–2022 and a notable spike in 2022. This steady rise shows growing local interest in electrification, lower running costs and reliable hot water repair and replacement options that do not lock households into rising gas prices.
Hot Water Rebates, Tariffs & Savings
Interest in replacing old gas or electric hot water with efficient options is only increasing in Drouin, VIC. Homeowners are weighing up electric hot water vs gas hot water and looking at how a solar hot water rebate or heat pump hot water rebate can bring the hot water system price or cost down. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pumps, effectively discounting the solar hot water price or cost and heat pump hot water price or cost at the point of sale. On top of this, Victorian hot water rebate VIC programs can offer extra support for efficient upgrades, and in some cases an electric hot water system rebate is available when switching away from gas.
For many Drouin homes, these hot water rebate VIC options can cut the upfront hot water system price / cost by a substantial percentage, especially when combined with retailer discounts.
