The 2913 postcode, covering Nicholls, Casey, Franklin, Ginninderra Village, Ngunnawal, Palmerston and Taylor and surrounding areas, is home to around 14,426 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 Nicholls and the 2913 area, 232 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 Nicholls'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 Nicholls
Across Nicholls and the wider 2913 area, more households are swapping old gas and electric units for an energy efficient hot water system that keeps bills down without sacrificing comfort. With an average household size of 2.8 people and more than 13,800 dwellings, demand for reliable hot water is constant – from busy family homes to modern townhouses and apartments. Rising energy prices mean upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step.
Nicholls is well suited to efficient hot water. Local solar data from the CSIRO Ginninderra station shows mean daily solar exposure of around 17.3 MJ/m², which works out to roughly 4.8–5.0 kWh of sunshine per square metre per day across the year. That strong solar resource supports both a solar hot water heating system on the roof and high‑performance heat pump hot water, especially when paired with rooftop solar. With many homes owned with a mortgage (around 6,600) and a solid proportion owned outright, plenty of Nicholls residents are in a good position to invest in upgrades that lock in long‑term savings and boost property value.
In 2913 there is a mix of larger separate houses and over 3,300 townhouses and terraces, so there is no one “best hot water system Australia” wide – the right choice depends on roof space, access and hot water demand. For a typical family, hot water can be one of the biggest energy users in the home, so shifting from gas or an old electric hot water system to an energy efficient hot water system can deliver serious savings. Brands like Rheem heat pump hot water and Sanden heat pump units are popular with households chasing the most efficient hot water system, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common options for a full solar hot water installation with roof collectors and a solar hot water tank replacement when older cylinders fail.
Average annual bill savings in Nicholls will vary, but realistic ranges for a well‑designed hot water installation are:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water: save roughly $250–$600 per year. • Gas to solar hot water system: save about $200–$500 per year. • Old electric to modern electric hot water installation powered by rooftop solar: save around $250–$550 per year.
Efficient hot water systems have already made an impact locally. In Nicholls and the 2913 postcode, there have been 232 efficient hot water installations recorded, combining heat pump hot water installation and solar hot water installation projects. Install numbers jumped sharply around 2008–2011, peaking at 45 systems in 2009 and staying solid through the early 2010s before settling into a steady trickle of upgrades each year. This trend mirrors growing interest in electrification, lower running costs and moving from electric hot water vs gas hot water towards smarter options like heat pump vs solar hot water, or even solar hot water vs electric hot water powered by PV.
Many homeowners now think about hot water repair as a chance to upgrade rather than just like‑for‑like replacement. When an old tank fails, it is the ideal time to compare heat pump hot water price / cost, solar hot water price / cost and modern electric hot water system price / cost – especially when you factor in rebates. If you already have a system from brands like Rheem solar hot water or Rinnai solar hot water, a timely solar hot water repair or solar hot water tank replacement can restore performance and keep savings flowing for years.
Hot Water Rebates, Tariffs & Savings
Around Nicholls ACT, interest in replacing ageing gas units with a heat pump hot water system or upgrading to a more efficient electric hot water system is growing, helped along by generous incentives. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively act as a federal solar hot water rebate or heat pump discount, reducing the upfront cost of eligible systems. On top of that, ACT homeowners can often access state‑based support that works like a heat pump hot water rebate or electric hot water system rebate, depending on the program at the time.
For many Nicholls households, these hot water rebate ACT incentives can cut the installed cost of a new system by a substantial percentage, trimming years off the payback period. Combine a quality heat pump or solar hot water heating system with rooftop solar, smart tariffs and simple tools like timers or solar diversion, and it is common to save hundreds of dollars per year on bills. Over the life of the system, that adds up to thousands back in your pocket while also cutting emissions.
If you live in Nicholls and your current unit is old, noisy or running up big bills, it could be the perfect time to explore a hot water upgrade.
