With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Millwood and the 0822 area, 1,020 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Millwood's climate delivering an average of 6.1 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Millwood
In Millwood, hot water is a big part of everyday life, from busy family homes to local businesses. With power prices rising and more locals looking to move away from gas, there’s a clear shift towards an energy efficient hot water system – especially heat pump hot water, solar hot water and modern electric hot water systems. With an average of around 22.1 MJ/m² of sunshine a day (roughly 6.1 kWh/m²), Millwood’s Top End climate is perfect for a solar hot water system or a high‑efficiency heat pump hot water system that makes the most of that free energy.
Households in the 0822 area have an average of 3.8 people, so hot water demand is solid, and long showers or multiple loads of washing can really add up on the bill. Median household income sits around $1,347 a week, and there’s a mix of owned and rented homes, with almost 3,000 rented dwellings and more than 1,600 owned outright or with a mortgage. That makes choosing the best hot water system Australia can offer – one that’s reliable, affordable and efficient – a smart financial decision as well as a comfort upgrade. Swapping an old gas or electric hot water system for an energy efficient hot water system can cut hot water energy use dramatically, with annual hot water energy savings that really matter in Millwood’s heat.
Across the 0822 postcode, there’s a growing number of homes pairing rooftop solar with an efficient hot water system. Many families are weighing up heat pump vs solar hot water, or solar hot water vs electric hot water, to find the most efficient hot water system for their situation. For some, a solar hot water heating system with roof collectors and a well‑insulated solar hot water tank replacement makes sense. Others prefer a heat pump hot water system, which works like a reverse fridge and pulls heat from the warm NT air, even on cloudy days.
Typical annual bill savings in Millwood can look like this:
• Replacing an old electric hot water system with a quality heat pump hot water installation: around $400–$800 a year. • Switching from gas hot water to a heat pump hot water system: roughly $300–$700 a year. • Moving from gas to a solar hot water installation: about $300–$600 a year. • Upgrading an old electric unit to a modern electric hot water installation and using rooftop solar: around $200–$500 a year.
Brands like Rheem heat pump hot water and Rheem solar hot water are common choices for households wanting proven reliability, while Rinnai solar hot water and Sanden heat pump systems are popular with those chasing the best heat pump hot water system performance and very low running costs. Chromagen solar hot water also appears on a number of local roofs, especially where owners want a robust solar hot water repair network and easy parts availability.
Efficient hot water is not new to Millwood. There have already been 1,020 efficient hot water systems installed in the 0822 area, including both heat pump and solar hot water installations. Install numbers started slowly in the early 2000s, then jumped sharply from around 2008. Recent years like 2018 and 2019 were strong, with 74 and 123 installations respectively, and there has been steady activity through to 2024 and 2025. This pattern shows a clear local interest in electrification, lower running costs and cleaner hot water NT wide.
Hot Water Rebates, Tariffs & Savings
All of this interest is helped along by hot water rebate NT programs and Federal incentives. When you install a qualifying heat pump hot water system or solar hot water system in Millwood, Small‑scale Technology Certificates (STCs) can reduce the upfront heat pump hot water price or solar hot water price at the point of sale. On top of that, Northern Territory schemes and retailer offers may provide a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some cases. These discounts can effectively reduce system cost by a substantial percentage, bringing a premium Sanden heat pump or similar within reach for many families.
For a typical Millwood home, upgrading to an energy efficient hot water system can save hundreds of dollars a year, especially when combined with rooftop solar and smart controls. Using timers or solar‑diversion controls to run a heat pump or electric hot water system in the middle of the day lets you soak up cheap or free solar power instead of paying peak tariffs. That shortens the payback period and makes modern hot water repair and maintenance easier over the long term.
If you’re in Millwood and your current unit is old, noisy, running out of hot water or pushing your bills up, it’s a good time to check whether a hot water upgrade makes sense.
