Hot water systems in Rookwood

Across Rookwood, more households are rethinking their old gas and electric hot water systems and moving to energy efficient options like a modern heat pump hot water system, solar hot water system or well-sized electric hot water system. With an average household size of 2.9 people and more than 10,500 dwellings in the 2141 postcode, reliable hot water is non-negotiable – but so are power bills, especially when the median mortgage is over $2,250 a month and rents are pushing $468 a week.

Rookwood’s climate is actually well suited to efficient hot water. The local weather station records mean daily solar exposure of about 16.3 MJ/m², which works out to roughly 4.5 kWh of solar energy per square metre per day over the year. That strong sunlight helps a solar hot water heating system perform well and gives a handy boost to heat pump hot water systems, which work even better when the air is warmer. For many families and multi-generational households in the area, upgrading from an older gas or off-peak electric unit to an energy efficient hot water system can trim hundreds of dollars a year from bills, adding up to serious Annual Hot Water Energy Savings over the life of the unit.

In 2141, there is a mix of separate houses and a large number of apartments and townhouses, which means hot water demand varies from compact one-bedroom units to busy four-bedroom family homes. Hot water can easily account for a quarter of household energy use, so choosing the most efficient hot water system for your set-up matters. A quality heat pump hot water installation can cut running costs by around two-thirds compared with an old electric hot water system, while a well-designed solar hot water installation tied to rooftop solar can make showers and laundry incredibly cheap to run. For smaller properties or units, a modern electric hot water installation, especially when paired with solar PV, can still be a smart upgrade from gas.

• Old electric to heat pump hot water system: save roughly $350–$700 per year on bills. • Gas to heat pump hot water: save around $250–$600 per year, depending on usage. • Gas to solar hot water system: save about $250–$650 per year. • Old electric to new electric hot water system with solar: save around $200–$500 per year.

Hot Water Rebates, Tariffs & Savings

Across Rookwood, more owners and even some investors are replacing ageing gas storage units and power-hungry electric cylinders with heat pump hot water, modern electric hot water or a solar hot water system. A big driver is the range of Australian Government and NSW hot water rebate programs that help bring the hot water system price / cost down. Small-scale Technology Certificates (STCs) act like an upfront discount on eligible solar hot water systems and heat pump hot water installation, while state-based schemes can add a heat pump hot water rebate or solar hot water rebate on top. There are also incentives that can operate like an electric hot water system rebate when you swap out inefficient gear.

For a typical Rookwood family on a median total household income of around $1,800 a week, these rebates can effectively cut the installed cost of an energy efficient hot water system by a substantial percentage and shorten payback times to just a few years. Combine that with timers, smart controls or solar diversion – sending excess rooftop solar into your hot water tank – and the ongoing savings climb even higher. When you factor in lower maintenance, fewer hot water repair call-outs and the option of solar hot water tank replacement instead of a full system changeover, the long-term value becomes hard to ignore.
