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 Lake Mackay and the 0872 area, 606 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 Lake Mackay'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 Lake Mackay
In Lake Mackay, more locals are rethinking their old gas and electric units and upgrading to an energy efficient hot water system. With an average household size of about 3.6 people and a young median age of 29, families and shared homes use a lot of hot water every day. At the same time, power prices keep rising and many households are on modest incomes, so cutting running costs without sacrificing comfort just makes sense.
The Lake Mackay region enjoys outstanding sunshine, with mean daily solar exposure of around 22 MJ/m², or roughly 6.1 kWh/m² per day across the year. That strong desert sun is ideal for a solar hot water system or a modern heat pump hot water system, and it also helps newer electric hot water systems run more cheaply when paired with rooftop solar. For many homes, moving from electric hot water vs gas hot water to all‑electric, using a heat pump or solar hot water heating system, is the logical next step in lowering bills and emissions.
Across the 0872 postcode there are more than 3,200 occupied dwellings, mostly separate houses with plenty of roof space for solar. Many are rented, but there is still a solid base of homes owned outright or with a mortgage where owners can decide on a hot water upgrade. With large families common, hot water energy use can be one of the biggest loads in the house, so choosing the most efficient hot water system has a real impact.
In a typical Lake Mackay home, hot water can account for a quarter or more of electricity use. That is why efficient options like a heat pump hot water system or solar hot water vs electric hot water are getting more attention. Popular brands in the area include Rheem and Rinnai for both solar and electric hot water installation, while premium systems like Sanden heat pump units are known for very low running costs. Chromagen solar hot water is another option for those wanting a reliable solar hot water tank replacement with strong performance in high heat.
Average annual bill savings will vary by household size and tariffs, but realistic ranges for Lake Mackay look like this:
• Old electric to heat pump hot water installation: save about $400–$800 per year. • Gas to heat pump: save roughly $300–$700 per year, plus remove gas connection charges. • Gas to solar hot water installation: save about $250–$600 per year. • Old electric to modern electric hot water installation with rooftop solar: save around $300–$700 per year, depending on how much solar you self‑consume.
Efficient hot water systems are already taking off locally. In the 0872 postcode there have been 606 efficient hot water installations recorded, mainly heat pump and solar hot water systems. Early interest peaked in the early 2000s, then surged again from 2018 onwards, with 76 installs in 2018 and solid numbers through to 2021.

Hot Water Rebates, Tariffs & Savings
Around Lake Mackay, more people are swapping out old gas or ageing electric units for efficient options like a heat pump hot water system, a modern electric hot water system or a roof‑mounted solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water heating systems, effectively acting like an upfront discount. On top of that, Northern Territory schemes and retailer offers can operate as a hot water rebate nt, including targeted heat pump hot water rebate or solar hot water rebate programs when available.
When you combine these incentives, the heat pump hot water price / cost or solar hot water price / cost can drop by a substantial percentage compared with the full retail hot water system price / cost. That helps shorten payback times to just a few years, especially if you run the unit on a solar‑friendly tariff or use timers and solar diversion to heat water during the middle of the day. For some homes, choosing the best heat pump hot water system or a quality rheem solar hot water or rinnai solar hot water setup can save hundreds of dollars per year and significantly cut emissions. Electric hot water system rebate options can also make a modern electric hot water system competitive for smaller homes or those planning more solar.
Whether you are comparing heat pump vs solar hot water, weighing up solar hot water vs electric hot water, or looking at rheem heat pump hot water, sanden heat pump or chromagen solar hot water, it pays to get local advice. If your current unit is leaking, unreliable or more than 10 years old, now is a good time to think about hot water repair versus full solar hot water tank replacement and a fresh hot water installation.
If you live in Lake Mackay and want to future‑proof your home, an energy efficient hot water system is one of the smartest upgrades you can make.
