The local climate makes upgrades a logical next step. Valley View’s weather station shows mean daily solar exposure of around 17.3 MJ/m², or roughly 4.8 kWh/m² per day across the year. That strong sunlight supports both a solar hot water heating system and a high-performance heat pump hot water system, especially when paired with rooftop solar. In a suburb where many households are paying around $1,471 a month on the mortgage and juggling family budgets, the annual hot water energy savings from moving to an energy efficient hot water system can make a real difference.
Modbury North has a healthy mix of families and older residents, and a big share of homes are owned outright or with a mortgage, which makes long-term upgrades attractive. Many existing properties still run gas or older electric hot water, so switching to a heat pump vs solar hot water, or even a better electric hot water system, is becoming a common question. Local installers regularly work with trusted brands like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium units such as the Sanden heat pump, helping households choose the most efficient hot water system for their needs.
In 5092 there are already 286 efficient hot water systems installed, combining heat pump hot water installation and solar hot water installation. Installations really picked up around 2008–2010, with a peak of 35 systems in 2009 as rebates kicked in, and there has been steady interest through to 2025. That trend shows more Modbury North residents are looking to cut running costs, move towards all-electric homes and reduce reliance on gas.
Typical hot water installation choices depend on family size and roof space. A three-bedroom Modbury North home might look at a 200–300 litre heat pump hot water system or a similar-sized solar hot water tank replacement with electric boosting. For smaller households or units, a compact electric hot water installation can still work well, especially when matched to rooftop solar. When you compare hot water energy use to overall household energy, hot water can be a big slice of the bill, so upgrading delivers noticeable savings.
Below are indicative average annual bill savings for local upgrade scenarios (actual hot water system price / cost and performance will vary):
• Old electric to heat pump hot water system: save roughly $400–$800 per year. • Gas to heat pump hot water system: save around $300–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water with solar: save roughly $250–$500 per year.
Many residents ask about solar hot water vs electric hot water, or electric hot water vs gas hot water. With good solar exposure in SA and rising gas prices, the balance is shifting towards efficient electric options. A quality heat pump hot water system, such as the Sanden heat pump or a high-efficiency Rheem or Rinnai unit, can often be the best heat pump hot water system choice for households wanting low running costs without large roof collectors. For others, a chromagen solar hot water or rinnai solar hot water setup, or similar solar hot water tank replacement, offers a reliable solar hot water heating system with long-term savings.
When it comes to solar hot water price / cost or heat pump hot water price / cost, rebates make a big difference. Federal Small-scale Technology Certificates (STCs) effectively act as an upfront solar hot water rebate or heat pump hot water rebate for eligible systems, reducing the invoice on day one. On top of that, South Australian programmes can offer a hot water rebate SA for certain efficient upgrades, and there may be an electric hot water system rebate when you move away from gas. Together, these incentives can cut the installed cost by a substantial percentage and shorten payback times to just a few years, especially if you already have rooftop solar.
Smart tariffs and timers can push savings even further in Modbury North. Running a heat pump in the middle of the day on solar, or using a diverter to send excess PV into an electric hot water system, means more free energy and less grid reliance. Many homes see hundreds of dollars per year in extra savings just by tuning their controls.
If your current unit is ageing, noisy or struggling to keep up, it is a good time to check whether your Modbury North home is ready for a hot water upgrade.
