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 Southport 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 Southport'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 Southport
In Southport, more locals are rethinking their old hot water system and switching to energy‑efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With an average household size of around 3.8 people and plenty of family homes across the 5,400+ dwellings in the 0822 area, reliable and affordable hot water is essential. Power prices keep climbing, so upgrading from older gas or electric units to an energy efficient hot water system is a logical next step, especially when you factor in the annual hot water energy savings many Southport households are already seeing.
Southport’s solar exposure is a real advantage. The local weather station records mean daily solar exposure of about 21.2 MJ/m², which is roughly 5.9 kWh of sun energy per square metre per day. That strong sunlight underpins great performance from both a solar hot water heating system and a quality heat pump hot water system, particularly when paired with rooftop solar. With a relatively young median age of 30 and many homes either owned with a mortgage or in long‑term rentals, there is strong interest in cutting running costs and future‑proofing homes with the most efficient hot water system possible.
Across the 0822 postcode, efficient hot water systems are becoming more common as people realise how much of their electricity bill is tied up in hot water. For a busy family of four or five, hot water demand is high, so moving to a heat pump hot water installation or solar hot water installation can make a big dent in overall usage. Some households still rely on older gas units, but there is growing curiosity about heat pump vs solar hot water, and even solar hot water vs electric hot water when combined with rooftop PV.
Typical annual bill savings for Southport homes can look like this:
• Old electric to heat pump hot water system: save about $400–$800 per year. • Gas to heat pump: save around $300–$700 per year. • Gas to solar hot water system: save roughly $300–$600 per year. • Old electric to modern electric hot water installation with good solar: save $250–$500 per year.
Local installers are working with trusted brands such as Rheem heat pump hot water units, Rheem solar hot water systems, Sanden heat pump models and Rinnai solar hot water setups, helping Southport households choose from some of the best heat pump hot water system and solar options on the market. These sit comfortably alongside efficient electric hot water installation choices for homes going all‑electric.
In Southport there have already been 1,020 efficient hot water installations, combining both heat pump and solar hot water systems. Install numbers started slowly in the early 2000s, then picked up around 2008–2010, with another strong surge from 2015 onwards. Recent years such as 2018, 2019 and 2020 saw particularly high uptake, reflecting growing interest in electrification, lower running costs and reducing reliance on gas. Even in 2023–2025, steady installations show that hot water repair and replacement jobs are increasingly turning into efficient upgrades rather than like‑for‑like swaps.
Hot Water Rebates, Tariffs & Savings
More Southport homeowners and landlords are now replacing old gas or resistive electric units with efficient options like heat pump hot water, solar hot water or a modern electric hot water system. Australian Government incentives such as Small‑scale Technology Certificates (STCs) can lower the effective solar hot water price / cost or heat pump hot water price / cost, while NT‑specific schemes and retailer offers may provide a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in some programs. These hot water rebate NT incentives can effectively knock a substantial percentage off the upfront hot water system price / cost, shortening the payback period.
For many Southport homes, an efficient hot water upgrade can trim hundreds of dollars a year from energy bills. When you combine rebates with good tariffs, rooftop solar and simple tricks like using timers or solar diversion to run a heat pump during the middle of the day, the payback on a new solar hot water heating system or heat pump can be cut significantly. Over the life of the system, that can add up to thousands in savings, especially when you avoid repeated hot water repair costs on an ageing unit or a premature solar hot water tank replacement caused by corrosion or leaks.
If you are weighing up electric hot water vs gas hot water, or comparing heat pump vs solar hot water for your place in Southport, it pays to get personalised advice. Talk to experienced local hot water installers who work with leading brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and Chromagen solar hot water to find the best hot water system Australia can offer for your budget and roof. With Southport’s excellent sun, strong interest in sustainability and plenty of family‑sized homes, an energy efficient hot water system is one of the simplest ways to cut bills, reduce emissions and future‑proof your property.
