Hot water systems in Willmot
Across Willmot and the wider 2770 area, more households are swapping old gas and ageing electric units for an energy efficient hot water system. With an average household size of around three people and more than 18,000 occupied dwellings in the postcode, hot water is a big slice of local power bills. Median household income sits near $1,326 a week, so it makes sense that families are looking for smarter ways to cut costs without giving up long showers.
Willmot is actually well suited to an upgrade. The local weather station records mean daily solar exposure of about 16.1 MJ/m², which works out to roughly 4.5 kWh of sunshine per square metre per day over the year. That is solid fuel for a solar hot water system or a modern heat pump hot water system, both of which use free energy in the air and sun to slash running costs. Shifting from older gas or resistive electric hot water to a modern solar hot water heating system or high efficiency electric hot water system is a logical next step if you are already watching power prices or thinking about an all‑electric home.
In a suburb where more than 9,000 dwellings are rented and over 8,900 are owned outright or with a mortgage, there is strong demand for reliable, low running cost hot water. Families with kids, shift workers and multi‑generational households all lean heavily on their hot water system, so choosing the most efficient hot water system you can afford makes a real difference. Many homes are still on older gas or basic electric hot water, which can quietly chew through 20–30% of a home’s total energy use.
Typical savings from a hot water upgrade in Willmot look like this:
• Old electric to heat pump hot water system: save roughly $350–$700 a year on bills. • Gas to heat pump vs solar hot water: often $250–$600 a year, depending on usage. • Gas to solar hot water system with PV: save around $300–$650 a year. • Old electric to modern electric hot water installation with rooftop solar: around $250–$500 a year.
Brands like Rheem heat pump hot water and Rheem solar hot water are common choices locally, along with Rinnai solar hot water for roof‑mounted systems and Japanese‑designed Sanden heat pump units for very low running costs. For many households comparing heat pump vs solar hot water, a quality Sanden heat pump or similar is now considered among the best heat pump hot water system options in Australia. Others prefer a chromagen solar hot water style setup, pairing a solar hot water tank replacement with existing PV.
In the 2770 postcode there have already been 915 efficient hot water installations recorded, covering both heat pump hot water installation and solar hot water installation. Install numbers jumped sharply around 2009–2011, with a peak of 324 systems in 2010 when incentives were strongest, and have continued at a steady, smaller pace since. This trend shows growing local interest in hot water NSW upgrades, electrification and lower running costs, even as rebate programs change over time.
Hot Water Rebates, Tariffs & Savings
Across Willmot there is rising interest in replacing old gas or electric hot water with an energy efficient hot water system, whether that is a heat pump hot water system, a modern electric hot water system or a roof‑mounted solar hot water system. Homeowners can often tap into Australian Government Small‑scale Technology Certificates (STCs) plus state‑based heat pump hot water rebate or solar hot water rebate programs. In some cases, an electric hot water system rebate may also apply when moving away from gas.
These incentives effectively cut the hot water system price / cost by a substantial percentage, bringing the heat pump hot water price / cost or solar hot water price / cost down to something much closer to a standard electric hot water system. For many Willmot households, that means typical savings of hundreds of dollars per year on bills, with payback times shrinking further if you use timers or solar diversion to run the system when rooftop solar is producing. When you compare solar hot water vs electric hot water, or electric hot water vs gas hot water, the numbers increasingly favour efficient electric options in NSW, especially when a hot water rebate nsw applies.
If your current unit is rusty, unreliable or you are paying too much for hot water repair, it is often smarter to put that money towards a new system. Whether you are looking at electric hot water installation, solar hot water repair and upgrades, or a full solar hot water tank replacement, it is worth checking your eligibility for rebates and getting a clear view of total hot water system price / cost before it fails completely.
