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 Pulumpa 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 Pulumpa'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 Pulumpa
Across Pulumpa and the wider 0822 region, more households are switching to energy efficient hot water systems to keep bills down in the Territory heat. With an average household size of around 3.8 people and more than 5,400 dwellings, hot water is a big chunk of energy use for local families. Many homes still run older gas or electric units, so upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step. With strong sunshine averaging about 21.2 MJ/m² per day (roughly 5.9 kWh/m²/day), Pulumpa is well suited to a solar hot water heating system or a high performance heat pump that thrives in warm, humid conditions.
Local census data shows a young community with a median age of just 30 and a high share of rented dwellings alongside homes owned outright or with a mortgage. That mix means landlords and homeowners alike are looking for reliable hot water installation options that reduce running costs and future proof properties. When you consider the annual hot water energy savings possible from replacing an old gas or electric hot water system, it is easy to see why efficient hot water is becoming part of the shift to all electric homes in the NT.
In the 0822 area, larger family homes dominate, with most properties having three or more bedrooms and higher than average hot water demand. That makes choosing the most efficient hot water system critical. A quality heat pump hot water installation can cut hot water energy use by up to two thirds compared with an older electric storage unit, while a well designed solar hot water installation can use Pulumpa’s strong sun to provide most of your hot water for much of the year. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for households wanting the best heat pump hot water system, while Rheem solar hot water and Chromagen solar hot water are trusted choices for roof mounted solar hot water tank replacement or upgrades.
Typical annual bill savings in Pulumpa look like this: • Old electric to heat pump hot water system: save around $400–$800 per year • Gas hot water to heat pump: save roughly $300–$700 per year • Gas hot water to solar hot water system: save about $300–$750 per year • Old electric to modern electric hot water installation backed by rooftop solar: save around $250–$600 per year
These ranges will vary with usage, tariffs and whether you are running a solar hot water vs electric hot water setup or using timers and smart controls to match solar generation.
Pulumpa has already seen 1,020 efficient hot water systems installed, combining heat pump and solar hot water installations. Install numbers were modest in the early 2000s, then jumped sharply from around 2008, with peaks in 2015, 2018 and especially 2019 when 123 systems went in. Even in recent years, from 2020 through to 2024 and 2025, dozens more systems have been added each year. This steady growth shows how strongly locals are embracing efficient hot water, electrification and lower running costs, especially as energy prices rise and more homes add solar PV.
Hot Water Rebates, Tariffs & Savings
Around Pulumpa, interest is growing in replacing ageing gas or electric units with efficient heat pump hot water, solar hot water or a modern electric hot water system that works hand in hand with rooftop solar. Homeowners can typically access Federal incentives through Small scale Technology Certificates (STCs), which reduce the upfront hot water system price for eligible systems like a solar hot water heating system or heat pump. On top of this, NT residents may be able to tap into state based heat pump hot water rebate or solar hot water rebate programs when available, and in some cases an electric hot water system rebate for efficient replacements.
These hot water rebate NT incentives can effectively trim the heat pump hot water price or solar hot water price by a substantial percentage, shortening payback periods to just a few years when combined with solar PV. For many Pulumpa households, that means hundreds of dollars a year off bills and a much lower lifetime hot water system cost. Using simple tools like timers or solar diversion controls to heat water during the middle of the day can further boost savings, especially when weighing up heat pump vs solar hot water or solar hot water vs electric hot water options.
If you are in Pulumpa and your current unit is old, noisy or unreliable, now is a smart time to consider a hot water upgrade. Whether you are comparing electric hot water vs gas hot water, looking for the best hot water system Australia offers, or deciding between Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or other energy efficient hot water system brands, it pays to talk to experienced local installers. With Pulumpa’s strong solar exposure and growing focus on sustainability, efficient hot water can help cut emissions, reduce running costs and future proof your home.
