That level of sunshine is ideal for a solar hot water heating system and also helps a heat pump hot water system run more efficiently, especially when paired with rooftop solar. For families on a median household income of about $2,205 a week, the annual hot water energy savings from upgrading can easily reach hundreds of dollars, particularly when moving from older electric hot water vs gas hot water units to today’s most efficient hot water system options.
In 3178, most homes are three or four bedroom houses, so a correctly sized hot water installation is important to avoid running out of hot water or overspending on a system that is too large. Many homes are already using solar power, and pairing that with a heat pump hot water installation or solar hot water installation can dramatically cut hot water energy use compared to the rest of the household load. Brands like Rheem heat pump hot water systems and Rheem solar hot water units are popular for reliability, while Sanden heat pump and Rinnai solar hot water systems are often chosen for premium efficiency and quiet operation.
Typical annual bill savings in Rowville for a well designed hot water upgrade can look like this:
• Old electric to heat pump hot water system: save around $400–$800 per year. • Gas to heat pump hot water system: save around $300–$600 per year. • Gas to solar hot water system: save around $250–$550 per year. • Old electric to modern electric hot water installation with solar: save around $250–$500 per year.
Rowville has already seen 805 efficient hot water systems installed, combining heat pump and solar hot water installations. Installations were modest in the early 2000s, then jumped in 2008 and 2009 when rebates were first strong, and have surged again from 2016 onwards, with notable peaks in 2016, 2019 and 2020. Even in recent years, dozens of systems are going in each year, showing strong local interest in electrification, lower running costs and more energy efficient hot water system choices. As systems age, there is also steady demand for hot water repair, solar hot water repair and solar hot water tank replacement to keep existing units performing well.
Hot Water Rebates, Tariffs & Savings
Homeowners in Rowville are increasingly replacing old gas and resistive electric units with efficient options like heat pump hot water, solar hot water and high performance electric hot water system setups.
