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 Carrs Island and the 2460 area, 2,830 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 Carrs Island's climate delivering an average of 5.0 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 Carrs Island
Across Carrs Island and the wider 2460 area, more households are switching to energy efficient hot water systems to beat rising power prices and move away from ageing gas units. With an average household size of around 2.4 people and more than 10,000 separate houses in the postcode, reliable hot water is essential – but so is keeping running costs under control. Many homes still rely on older gas or electric hot water, 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. Local solar data from the Grafton Olympic Pool station shows strong sunshine, with mean daily solar exposure of about 18 MJ/m² – roughly 5 kWh/m² per day – which is ideal for both a solar hot water heating system and high performance heat pump hot water.
Income levels in the 2460 postcode are modest, with median household income around $1,165 a week and a large share of homes owned outright or with a mortgage. That makes long term bill savings from the right hot water system even more important. A well designed heat pump hot water installation or solar hot water installation can dramatically cut the share of your power use that goes into water heating, which is often 20–30% of a typical home’s energy. For many Carrs Island families, the annual hot water energy savings from replacing an old electric hot water system can easily run into hundreds of dollars a year.
In Carrs Island and surrounds, we see steady demand for three main options: efficient heat pump hot water, roof mounted solar hot water, and newer, well insulated electric hot water systems that work hand in hand with rooftop solar. Brands like Rheem heat pump hot water, Sanden heat pump and Stiebel Eltron are popular for those chasing the most efficient hot water system, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a roof based solar hot water system. Choosing the best hot water system Australia has to offer for your home comes down to your roof space, budget, and whether you already have solar.
When you look at system sizes and savings for Carrs Island, the typical three bedroom home with 2–4 people will usually suit a 250–315 litre heat pump hot water system or solar hot water tank replacement, while larger family homes may need 315–400 litres. Many properties already have rooftop solar, so a modern electric hot water installation on a timer can still be an energy efficient hot water system if it mainly runs on your own solar. For others, the heat pump vs solar hot water choice comes down to roof space and upfront hot water system price.
Average annual bill savings in Carrs Island are often in these ranges:
• Replacing old electric with a heat pump hot water system: save around $400–$800 per year. • Switching gas hot water to heat pump: save around $250–$600 per year. • Switching gas to a solar hot water heating system: save around $300–$700 per year. • Upgrading old electric to a modern electric hot water system run on solar: save around $250–$500 per year.
Across the 2460 postcode, there have already been 2,830 efficient hot water systems installed, combining both heat pump and solar hot water. Installations really took off around 2008–2011, with peaks of 552 installs in 2009 and strong numbers in 2010 and 2011, then a second bump in 2018. While yearly installations have eased back more recently, with dozens of systems still going in each year, it shows a clear, long term trend towards electrification, lower running costs and cleaner hot water in Carrs Island.
