Upgrading from an older gas or off‑peak electric unit to an energy efficient hot water system is one of the easiest ways to cut running costs. Dunolly’s mean daily solar exposure sits at about 16.9 MJ/m², which is roughly 4.7 kWh of solar energy hitting each square metre of roof every day across the year. That strong sunlight helps both a solar hot water heating system and a quality heat pump hot water system perform well, giving reliable hot water while slashing electricity use. For many Dunolly homes, annual hot water energy savings can easily reach hundreds of dollars, especially when shifting from bottled gas or very old resistive electric units.
Around 367 homes in the area are owned outright and another 177 are mortgaged, so plenty of owner‑occupiers are in a good position to invest in hot water installation that adds value and comfort. With an older population (median age 56), reliability and low maintenance matter just as much as the hot water system price or cost. That is where proven brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water systems stand out, offering long warranties and high efficiency.
Across postcode 3472, 67 efficient hot water systems have already been installed, including both heat pump hot water installation and solar hot water installation. Installations really picked up around 2008–2012, with a peak of 13 systems in 2009 and steady activity through to recent years. This steady trickle of upgrades shows growing local interest in electrification, lower running costs and getting ready for more rooftop solar in Dunolly.
For a typical Dunolly home, upgrading can deliver sizeable bill savings:
• Old electric to heat pump: save roughly $350–$700 per year • Gas to heat pump: save around $250–$600 per year • Gas to solar hot water: save about $200–$500 per year • Old electric to modern electric with solar: save roughly $200–$450 per year
Many households are also weighing up heat pump vs solar hot water, and solar hot water vs electric hot water. A modern heat pump is often the most efficient hot water system for shaded blocks or smaller roofs, while a roof‑mounted solar hot water tank replacement can be ideal for sunny, north‑facing homes. Either way, pairing your system with rooftop solar and a smart timer can make it the most energy efficient hot water system for your situation.
Hot Water Rebates, Tariffs & Savings
Across Victoria, including Dunolly, there is strong interest in replacing old gas or electric units with efficient options. Federal incentives like Small‑scale Technology Certificates (STCs) and state schemes can provide a solar hot water rebate, heat pump hot water rebate and even an electric hot water system rebate in some programs. These discounts can effectively trim the solar hot water price or cost and the heat pump hot water price or cost by a substantial percentage, cutting payback periods down to just a few years when combined with rooftop solar. Choosing off‑peak tariffs, using timers or solar diversion technology can further increase savings and make electric hot water vs gas hot water a clear win for many homes. For eligible households, hot water rebate VIC programs can meaningfully reduce the upfront hot water system price or cost and make high‑quality systems like Rheem solar hot water, Rinnai solar hot water or a Sanden heat pump far more affordable.
