The 2229 postcode, covering Port Hacking, Caringbah, Caringbah South, Dolans Bay, Lilli Pilli, Taren Point and Warumbul and surrounding areas, is home to around 12,138 households. 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 Port Hacking and the 2229 area, 533 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 Port Hacking's climate delivering an average of 4.6 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 Port Hacking
Across Port Hacking, more homeowners are swapping old gas and tired electric units for an energy efficient hot water system that actually suits the way they live. With an average household size of around 2.6 people and more than 8,000 homes owned outright or with a mortgage, many locals are looking for long‑term savings rather than quick fixes when it comes to their hot water system.
Port Hacking’s coastal climate and strong sunshine make it ideal for efficient hot water. The nearby Cronulla South station records mean daily solar exposure of about 16.6 MJ/m², or roughly 4.6 kWh/m² per day over the year. That level of solar energy supports both a high‑performing solar hot water system and a modern heat pump hot water system, especially when paired with rooftop solar. For families juggling a median weekly household income of around $2,235 and rising power prices, upgrading from older gas or resistive electric hot water to a modern heat pump hot water installation or solar hot water installation can deliver substantial annual hot water energy savings.
In the 2229 area there are more than 11,000 occupied dwellings, from separate houses through to townhouses and apartments, so hot water demand is constant. Many homes are still on gas or older cylinders, which means higher running costs than newer options like a heat pump hot water system or efficient electric hot water system with smart controls. Locals comparing heat pump vs solar hot water are often weighing upfront hot water system price against long‑term bill reductions and roof space. Brands such as Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are common choices for families wanting the most efficient hot water system they can reasonably fit and afford, while Chromagen solar hot water and Rheem solar hot water remain popular for established homes with good north‑facing roof area.
Typical annual bill savings in Port Hacking can look like:
• Old electric to heat pump hot water system: save roughly $400–$800 per year. • Gas to heat pump hot water: save around $250–$600 per year. • Gas to solar hot water heating system: save about $300–$700 per year. • Old electric to modern electric hot water system running mostly on solar: save roughly $300–$600 per year.
Recent years have shown steady interest in efficient hot water in Port Hacking. There have been 533 efficient hot water installations recorded in the postcode, including both heat pump and solar hot water systems. Installations grew strongly through the late 2000s, peaking around 2009–2010, and while numbers have levelled out more recently, there are still new systems going in every year. That ongoing hot water installation activity reflects a clear local shift towards electrification, lower running costs and quieter, cleaner homes. Many of these systems replace ageing gas units, with households keen to compare solar hot water vs electric hot water and electric hot water vs gas hot water before they commit.
When it comes to hot water repair and upgrades, Port Hacking homeowners are also watching the hot water system cost and what help is available. Federal incentives such as Small‑scale Technology Certificates (STCs) can reduce the effective heat pump hot water price or solar hot water price by hundreds of dollars. On top of that, state‑based hot water rebate NSW programs can offer a heat pump hot water rebate or solar hot water rebate for eligible properties, and in some cases an electric hot water system rebate when replacing inefficient models. For many households, these hot water rebate NSW incentives can cut the upfront solar hot water tank replacement or heat pump upgrade cost by a substantial percentage, shrinking the payback period to just a few years. Add smart timers or solar‑diversion controls, and an energy efficient hot water system can run mostly when your solar is generating, further trimming bills.
Whether you are comparing the best hot water system Australia has to offer, shortlisting the best heat pump hot water system for a busy family, or planning an electric hot water installation to move fully off gas, it pays to get tailored advice. If your current unit is more than 10 years old, running out of hot water, or needing regular hot water repair, now is a good time to assess a hot water upgrade.
