With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
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 Numburindi 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 Numburindi'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 Numburindi
Across Numburindi and the wider 0822 region, more households are switching to an energy efficient hot water system to keep bills down in the NT heat. With an average household size of around 3.8 people and lots of families in larger separate houses, hot water demand is high, so an upgrade from an old gas or electric hot water system can deliver serious savings year after year.
The local climate is perfect for efficient hot water. The nearby Numbulwar weather station records around 22 MJ/m² of solar exposure a day across the year, which is roughly 6 kWh/m² of sunshine daily. That strong NT sun helps a solar hot water system or heat pump hot water system perform at its best, cutting the energy needed to heat your water. In an area where many homes are rented and median household income sits around $1,347 per week, reducing running costs without compromising comfort is a smart move. Swapping old gas or resistive electric units for a modern heat pump hot water or solar hot water heating system can trim a big chunk off annual hot water energy use.
In 0822, separate houses dominate, with over 4,700 standalone homes plus townhouses and a smaller number of flats and other dwellings. That means plenty of roof space for solar hot water installation and solar PV, and room on the ground for heat pump hot water installation beside the house. For many families, hot water can be the second biggest energy user after cooling, so choosing the most efficient hot water system makes a real difference over time.
Typical annual bill savings in Numburindi look like this:
• Old electric to heat pump hot water system: about $400–$800 per year • Gas to heat pump hot water system: about $300–$600 per year • Gas to solar hot water system: about $250–$550 per year • Old electric to modern electric hot water installation with good solar: about $250–$500 per year
Brands like Rheem, Rinnai, Sanden and Thermann have become familiar names locally, with options ranging from rheem solar hot water and rheem heat pump hot water to rinnai solar hot water, Sanden heat pump units and Thermann heat pump models. Many locals looking for the best hot water system Australia offers are comparing the best heat pump hot water system for the tropics against a quality solar hot water vs electric hot water setup. For some homes, a robust electric hot water installation paired with solar PV and a timer can be the most practical energy efficient hot water system, especially where roof layout does not suit a solar hot water tank replacement.
Recent years show a clear trend towards efficient hot water in Numburindi. There have already been around 1,020 efficient hot water installations in the 0822 postcode, combining heat pump and solar hot water systems. Install numbers started very small in the early 2000s, then jumped sharply around 2008 and 2015, with a peak of 123 systems in 2019 and strong numbers through 2020 and 2021. Even with some easing since then, steady installations in 2022–2025 show growing local interest in electrification, lower running costs and moving away from gas hot water where possible.
Hot Water Rebates, Tariffs & Savings
Across Numburindi NT, more households are looking at heat pump vs solar hot water and even modern electric hot water vs gas hot water as older systems fail or power prices rise. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible solar hot water installation and heat pump hot water installation, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that reduces the hot water system price. NT homeowners may also be able to access additional hot water rebate nt style programs from time to time, and some retailers offer tariff options that reward off-peak or solar-friendly operation.
When you combine rebates with strong sunshine and smart controls, the payback on an efficient hot water upgrade can be surprisingly quick. A quality heat pump hot water system or solar hot water heating system can save hundreds of dollars per year, and using timers or solar-diversion to run your electric hot water system when your PV is generating can cut the effective heat pump hot water price or solar hot water price over its life. For some households, rebates and discounts can bring the upfront solar hot water system cost or heat pump hot water cost down by a substantial percentage, making it easier to move to a fully electric, low-emission home.
If your current unit is older, noisy or struggling to keep up, it could be the right time to look at options like chromagen solar hot water, rheem solar hot water, rinnai solar hot water or a Sanden heat pump to find the most efficient hot water system for your needs. Efficient electric hot water system rebate offers, where available, can also help when replacing an ageing tank with a modern, well-insulated model that works neatly with rooftop solar.
