Upgrading from older gas or electric hot water to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step for many Northcote homes.
Northcote’s solar exposure, averaging about 15 MJ/m² per day (roughly 4.2 kWh/m²/day), gives a solid foundation for both a solar hot water heating system and high performance heat pump hot water. That sunlight, combined with rising electricity and gas prices, means the annual hot water energy savings on offer can be substantial when you move to the most efficient hot water system you can reasonably afford. With a healthy mix of separate houses and townhouses as well as more than 2,300 flats and apartments, there’s a suitable hot water installation option for almost every property type.
In 3070, demand is growing for brands such as Rheem heat pump hot water units, Sanden heat pump systems and Rinnai solar hot water setups, along with Chromagen solar hot water options for homes with good roof space. Many locals are also comparing heat pump vs solar hot water to decide what fits best with their existing solar PV, tariffs and roof layout, as well as looking at electric hot water vs gas hot water when planning an all electric home. For some, a modern electric hot water installation paired with rooftop solar is the simplest path; for others, a dedicated solar hot water installation or heat pump hot water installation delivers the lowest running costs.
Average bill savings will vary with usage and tariffs, but typical ranges in Northcote look like:
• Replacing an old electric hot water system with a quality heat pump: save around $300–$700 per year. • Swapping gas hot water for a heat pump hot water system: save roughly $250–$600 per year. • Upgrading gas to a solar hot water system: save about $200–$500 per year. • Replacing an old electric unit with a modern electric hot water system plus solar PV: save around $250–$550 per year.
Over time, these savings help offset the hot water system price / cost, whether you choose the best heat pump hot water system you can, a premium rheem solar hot water setup, a rinnai solar hot water package or a chromagen solar hot water system with a new solar hot water tank replacement. Many locals simply want the best hot water system Australia can offer within budget, and are increasingly asking which option is the most energy efficient hot water system for their particular home.
Northcote has already seen 736 efficient hot water systems installed, combining both heat pump and solar hot water installations. Installations ramped up sharply around 2008–2010, with peaks in 2010 and 2013 as rebates and rising power prices pushed people towards efficient hot water. While yearly numbers have eased since those highs, there is steady ongoing hot water installation activity from 2018 through to 2025, showing a consistent base of homeowners focused on electrification, lower running costs and sustainability. As systems age, we’re also seeing more hot water repair and solar hot water repair work, plus replacements where the heat pump hot water price / cost or solar hot water price / cost is weighed up against sticking with older technology.
Hot Water Rebates, Tariffs & Savings
In Northcote, interest in replacing old gas or electric units with an energy efficient hot water system is rising as residents look to cut bills and emissions. Federal incentives such as Small-scale Technology Certificates (STCs) can reduce the upfront hot water system price / cost for eligible heat pump and solar hot water systems. On top of that, Victorian hot water rebate programs often provide a heat pump hot water rebate or solar hot water rebate that can slash the installed heat pump hot water cost or solar hot water price / cost by a significant percentage. There are also schemes that can support an electric hot water system rebate when moving away from gas.
For many Northcote households, these hot water rebate VIC programs mean a quality sanden heat pump or rheem heat pump hot water system can pay for itself in just a few years, especially when paired with solar and smart timers to heat water in the middle of the day. Typical savings of hundreds of dollars per year are realistic, and when you add in the hot water rebate vic incentives, the payback period for a new solar hot water vs electric hot water upgrade can shrink considerably. Using solar diversion, off peak tariffs and load control also helps make your hot water VIC bills even lower.
