Hot Water Systems in Millers Creek

Hot water systems in Millers Creek

In Millers Creek, hot water is something you really notice when it is not working. With power prices rising and many homes looking to move away from bottled or mains gas, more locals are turning to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. In a small community of around 167 people and an average household size of just 1.7, a well sized hot water system can make a big difference to both comfort and running costs.

Millers Creek is almost purpose built for efficient hot water. The town enjoys strong sunshine year round, with average solar exposure of about 20.4 MJ/m² a day – roughly 5.7 kWh/m² of solar energy. That is ideal for a solar hot water heating system or a high quality heat pump hot water system that pulls warmth from the air. With median household incomes around $1,761 a week and many dwellings rented rather than owned outright, choosing the most efficient hot water system is a practical way to keep ongoing bills down while still enjoying reliable hot showers.

Across the 5720 postcode there are 90 occupied dwellings, most of them three bedroom separate houses, so hot water demand is steady even with smaller household sizes. Hot water can easily account for a quarter of total household energy use, especially in older homes still running a basic electric storage unit or an ageing gas system. Upgrading from gas or an old electric hot water system to an energy efficient hot water system is a logical next step after rooftop solar, and many Millers Creek properties are now looking at heat pump vs solar hot water to decide what suits their roof space, usage patterns and budget.

Typical annual savings for Millers Creek homes can look like this:

• Old electric to heat pump hot water installation: save around $350–$700 per year. • Gas to heat pump hot water system: save roughly $250–$600 per year. • Gas to solar hot water installation: save about $300–$650 per year. • Old electric to modern electric hot water installation with rooftop solar: save around $200–$500 per year.

Brands like Rheem and Rinnai are popular locally for both solar hot water and efficient electric units, with options such as Rheem solar hot water, Rheem heat pump hot water and Rinnai solar hot water all designed for harsh Australian conditions. For those chasing the best heat pump hot water system on the market, premium units such as Sanden heat pump systems are known for very low running costs in sunny, dry climates like Millers Creek. Many locals also ask which is the best hot water system Australia wide; the answer usually depends on whether you want the absolute most efficient hot water system possible or the lowest upfront hot water system price.

In Millers Creek there have already been 32 efficient hot water systems installed, combining both heat pump and solar hot water installation jobs. The data shows just how quickly interest has grown: a single installation back in 2008, then a long quiet period, followed by 3 installs in 2023 and a big jump to 23 installs in 2024, with more already recorded in 2025. This recent spike reflects a strong local shift towards electrification, lower running costs and using the region’s excellent solar resource rather than paying for gas.

Hot Water Rebates, Tariffs & Savings

All of this activity is helped along by generous hot water rebate SA programs and national incentives. Even if you are simply replacing an old electric unit with a more efficient electric hot water system, there may be an electric hot water system rebate available. For solar hot water vs electric hot water, federal Small-scale Technology Certificates (STCs) can reduce the upfront solar hot water price / cost, while state-based schemes can offer a heat pump hot water rebate that cuts the heat pump hot water price / cost significantly. In some cases, combined discounts and solar hot water rebate support can shave 30–50% off the installed solar hot water price / cost or heat pump hot water price / cost. That can turn a payback period of eight to ten years into something closer to four to six years, especially if you also use timers or solar diversion to run your hot water system during the middle of the day. For many households looking at solar hot water vs electric hot water or electric hot water vs gas hot water, these incentives are the tipping point that makes an upgrade an easy decision.
