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 East Arm 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 East Arm's climate delivering an average of 5.9 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 East Arm
In East Arm, more locals are rethinking their hot water system and shifting to energy efficient options like a modern heat pump hot water system, solar hot water system or well‑insulated electric hot water system. With an average household size of around 3.8 people and a young median age of 30, families here use plenty of hot water for showers, laundry and cleaning, so running costs really add up. Many homes are rented, but there are still well over 1,600 dwellings owned outright or with a mortgage, which makes a hot water upgrade a smart long‑term investment.
East Arm’s climate is ideal for efficient hot water. The area enjoys mean daily solar exposure of about 21.1 MJ/m², which works out to roughly 5.9 kWh of sunshine per square metre per day. That strong Top End sun helps a solar hot water heating system and a quality heat pump hot water system perform at their best, slashing electricity use compared with older gas or resistive electric units. For households upgrading from old gas or electric hot water, annual hot water energy savings can be substantial, especially when paired with rooftop solar.
Across the 0822 postcode there are more than 5,400 occupied private dwellings, with most being separate houses. That suits roof‑mounted solar hot water installation and compact heat pump hot water installation on the side of the home. As energy prices rise faster than median household incomes (around $1,347 a week), switching to the most efficient hot water system you can afford is becoming a practical way to keep bills under control and future‑proof the home.
Locally, we are seeing a mix of brands, from Rheem solar hot water and Rheem heat pump hot water units through to Sanden heat pump systems and Rinnai solar hot water solutions. These sit alongside more budget‑friendly electric hot water installation options for smaller homes or rentals. When people compare heat pump vs solar hot water, they often weigh up roof space, orientation and whether they already have solar PV. In East Arm, the strong sun means both a heat pump hot water system and a solar hot water system can be the best hot water system Australia has to offer for this climate, depending on your site.
Average annual bill savings for East Arm households can look like this: • Old electric hot water to heat pump: $350–$700 per year • Gas hot water to heat pump: $250–$600 per year • Gas hot water to solar hot water: $300–$650 per year • Old electric to modern electric hot water with solar PV: $200–$450 per year
These ranges depend on usage, tariffs and how well you use timers or solar‑diversion to run an energy efficient hot water system when your solar is generating.
Recent installs in East Arm show how quickly things are changing. There have already been 1,020 efficient hot water systems installed in the 0822 area, including both heat pump and solar hot water installation projects. Installations were modest in the early 2000s, but picked up sharply from around 2008, peaking in 2019 with 123 systems in a single year. While numbers since 2020 have eased slightly, there is still steady demand, with dozens of households each year choosing hot water NT solutions that cut bills, support electrification and move away from gas hot water.
Hot Water Rebates, Tariffs & Savings
Around East Arm, more households are now replacing old gas or electric hot water with efficient options like a heat pump hot water system, updated electric hot water system or solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount off the heat pump hot water price / cost or solar hot water price / cost. On top of this, Northern Territory and other state‑based schemes can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate from time to time, further trimming the hot water system price.
For many East Arm homes, these hot water rebate NT incentives can reduce the system cost by a sizeable percentage and cut payback periods to just a few years, especially if you already have rooftop solar. Typical savings from an efficient hot water upgrade can run into hundreds of dollars a year, particularly when you use timers or solar‑diversion controls so your electric hot water vs gas hot water decision leans into cheap daytime solar. Choosing the best heat pump hot water system or a quality solar hot water vs electric hot water setup helps ensure reliable performance and low running costs for years.
If your existing unit is ageing, leaking or you are keen to go all‑electric, now is a good time to check whether your East Arm home is ready for a hot water upgrade. Whether you are considering a sanden heat pump, chromagen solar hot water tank replacement, rheem solar hot water, rinnai solar hot water or a simple solar hot water repair or hot water repair on an electric unit, working with experienced hot water installation specialists matters.
