With an average household size of about 2.7 people and more than 900 homes owned outright or with a mortgage, many local families are looking for long-term savings, not just the cheapest hot water system price on the day of install.
Lardner’s sunshine is a real asset. The local weather station records around 14.6 MJ/m² of solar exposure a day on average – roughly 4 kWh/m² – which is ideal for both a solar hot water system and a heat pump hot water system. That strong solar resource helps drive down running costs and boosts the performance of any solar hot water heating system, especially when paired with rooftop solar.

In a postcode dominated by separate houses (over 1,000 dwellings), hot water demand adds up quickly – from morning showers to evening dishes and laundry. Many homes still rely on gas or basic electric hot water, even though hot water energy use can be one of the biggest chunks of the power bill. Moving to the most efficient hot water system you can reasonably afford makes a noticeable difference. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, with options ranging from rheem solar hot water and rinnai solar hot water through to premium sanden heat pump and rheem heat pump hot water units for those chasing the best heat pump hot water system on the market.

• Old electric hot water system to a quality heat pump hot water system: $350–$750 a year • Gas hot water to heat pump: $250–$600 a year • Gas hot water to roof-mounted solar hot water system: $200–$550 a year • Old electric to modern electric hot water system with rooftop solar: $200–$500 a year
Local installation data backs up the trend. There have already been 255 efficient hot water installations (heat pump and solar hot water installation combined) recorded in the 3821 postcode. Installations really took off around 2009–2011, when Lardner saw peak years of new systems going in, and there has been steady interest right through to 2024–2025. Each new heat pump hot water installation or solar hot water tank replacement reflects a growing push towards electrification, lower running costs and more sustainable hot water VIC wide.
When you are weighing up heat pump vs solar hot water, or solar hot water vs electric hot water, rebates can tip the scales. Federal incentives in the form of Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pumps, effectively acting as a solar hot water rebate or heat pump hot water rebate that cuts the upfront solar hot water price / cost or heat pump hot water price / cost. Victoria also offers state-based support that can stack on top, and there are electric hot water system rebate options in some programs when you switch away from gas. For many Lardner households, these hot water rebate VIC schemes can knock a substantial percentage off the installed hot water system cost and shorten payback to just a few years, especially if you use timers or solar diversion to heat water when your PV system is generating.
