Hot water systems in North Hills
In North Hills, more homeowners are looking at upgrading their hot water system to something far more energy efficient. With power prices biting and many locals on modest household incomes of around $1,053 a week, shifting from old gas or electric hot water to a modern heat pump hot water system, solar hot water system or efficient electric hot water system just makes sense. For a small community of about 746 people, mostly living in separate houses and with an average household size of 2.2, hot water is a big chunk of the power bill – and a big opportunity for savings.
North Hills is well placed for efficient hot water. The Minburra weather station shows strong sunlight, with average annual solar exposure of about 19.3 MJ/m² per day – roughly 5.4 kWh/m²/day – ideal for a solar hot water heating system or an efficient heat pump hot water installation that runs cheaply during the day. With many homes owned outright and older residents (median age 54), reliability, low running costs and simple hot water repair options are just as important as cutting emissions.
Across the 5431 area, efficient hot water systems are slowly gaining ground. There have been 22 efficient hot water installations (mainly heat pump and solar hot water installation jobs), with noticeable peaks in 2010–2012 and a recent lift again in 2019 and 2023. That pattern reflects growing interest in electrification, lower running costs and getting away from ageing gas hot water. In a typical North Hills home, hot water can be a quarter or more of total energy use, so choosing the most efficient hot water system can really move the needle on bills.
When you look at hot water system price and ongoing cost, the upgrade paths are compelling. A quality heat pump hot water system might cost more upfront, but the heat pump hot water price is often offset by much lower running costs and rebates. A solar hot water price can also look higher on paper, but with our good solar exposure, a well‑sized rheem solar hot water or chromagen solar hot water setup can cover a large share of your hot water needs. Brands like Sanden heat pump and Rheem heat pump hot water are popular with locals wanting the best heat pump hot water system performance and quiet operation, while Rinnai solar hot water remains a trusted option for roof‑mounted solar hot water tank replacement.
Typical annual bill savings in a place like North Hills can look like:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water system: save roughly $250–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation with rooftop solar: save about $250–$500 per year.
Many homes are also weighing up heat pump vs solar hot water, and solar hot water vs electric hot water. The right choice depends on roof space, budget, and whether you already have solar PV. For some, a straightforward electric hot water installation tied to rooftop solar and a timer offers a very energy efficient hot water system without the complexity of collectors on the roof.
Hot Water Rebates, Tariffs & Savings
Across SA, including North Hills, interest is growing in replacing old gas or electric units with efficient options. Federal incentives like Small‑scale Technology Certificates (STCs) help cut the upfront hot water system price for eligible heat pump and solar hot water systems. On top of that, state‑based schemes can provide a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate when you install approved high‑efficiency models. For many North Hills households, these hot water rebate SA programs can effectively knock a substantial percentage off the system cost, bringing premium brands like Sanden or Rheem within reach.
Once installed, efficient systems often save hundreds of dollars a year, especially when combined with rooftop solar and smart controls. Using timers or solar‑diversion devices to run your electric or heat pump hot water during the middle of the day can shorten the payback period dramatically and make an all‑electric home more affordable and comfortable.
If you live in North Hills and your current unit is old, noisy or on its last legs, now is a smart time to compare options like heat pump hot water installation, solar hot water repair and replacement, or an efficient electric hot water vs gas hot water changeover.
