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 Cook and the 2614 area, 683 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 Cook's climate delivering an average of 4.8 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 Cook
Across Cook and the 2614 postcode, more households are swapping old gas and electric units for an energy efficient hot water system that keeps bills under control. With around 7,800 occupied dwellings and an average household size of 2.5 people, hot water demand is steady year‑round, especially for busy families and long‑term owner‑occupiers. Many homes here were built decades ago, 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.
Cook’s climate is ideal for efficient hot water. The local solar exposure averages about 17.3 MJ/m² per day, which is roughly 4.8 kWh of sunshine per square metre daily over the year. That strong solar resource helps a solar hot water heating system pre‑heat your water and boosts the performance of a quality heat pump hot water system. In an area where the median household income is about $2,250 per week and many homes are either owned outright or with a mortgage, cutting running costs without sacrificing comfort is a big win. Swapping from older gas or resistive electric hot water to efficient technology can deliver substantial annual hot water energy savings for Cook homeowners.
Around Cook, the mix of three‑ and four‑bedroom separate houses and townhouses means plenty of families with showers, baths and dishwashers running daily. That makes hot water energy use a significant slice of overall household energy. Many locals are now pairing rooftop solar with a solar hot water system or low‑running‑cost heat pump to get the most efficient hot water system they can. Brands like Rheem heat pump hot water units and Rheem solar hot water systems are popular, alongside premium options such as Sanden heat pump systems and Rinnai solar hot water solutions. For some homes, a robust Chromagen solar hot water setup or a simple modern electric hot water installation controlled by timers is the best fit.
Typical bill savings in Cook for a well‑designed hot water installation look like this:
• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water system: save about $250–$600 per year. • Gas to solar hot water system: save around $200–$500 per year. • Old electric to modern electric hot water system with solar: save about $200–$450 per year.
In Cook alone, there have already been 683 efficient hot water systems installed, combining heat pump hot water installation and solar hot water installation. Installations grew steadily through the 2000s, peaking around 2008–2011 as solar hot water price and heat pump hot water price dropped and incentives improved. After a quieter period, 2020 saw another spike with 64 installs, reflecting renewed interest in electrification and lower running costs. Each new system adds to community hot water energy savings and shows how strongly Cook residents are leaning into energy efficient hot water system upgrades.
Hot Water Rebates, Tariffs & Savings
Across Cook ACT, more people are replacing tired gas units and ageing cylinders with efficient options like heat pump hot water, updated electric hot water system models and solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively lowering the hot water system price at the point of sale. On top of that, ACT‑wide and other state‑based programs can offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some schemes. These discounts can cut the heat pump hot water cost or solar hot water price by a substantial percentage, often shaving years off the payback period. Combine rebates with rooftop solar, smart tariffs, timers or solar‑diversion controls, and you can turn your system into the most efficient hot water system your home has ever had.
When you are weighing up heat pump vs solar hot water, or comparing solar hot water vs electric hot water and electric hot water vs gas hot water, it pays to get local advice. The best hot water system Australia‑wide is not the same for every home. Some Cook households will suit a compact Sanden heat pump or Rheem heat pump hot water unit; others might lean towards roof‑mounted Rheem solar hot water, Rinnai solar hot water or Chromagen solar hot water with a ground tank. If you already have solar and your existing cylinder is failing, a solar hot water tank replacement or targeted solar hot water repair can make sense. If your old gas unit is leaking, a fast hot water repair and like‑for‑like electric hot water installation may be the first step towards an all‑electric home.
