With an average household size of around 3.1 people and more than 6,400 dwellings in the 2164 postcode, hot water demand is steady all year round. Power prices keep rising, so 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 for many families and local businesses.
Smithfield’s climate is well suited to efficient hot water. Nearby Greystanes records mean daily solar exposure of about 16.2 MJ/m², which is roughly 4.5 kWh/m² per day across the year. That strong sunlight helps a solar hot water heating system or heat pump hot water system run more efficiently, especially when paired with rooftop solar. With a median household income of about $1,401 a week and solid home ownership levels, shifting from older gas or off‑peak electric hot water to the most efficient hot water system you can afford can make a real dent in running costs over the long term.
In 2164, separate houses dominate, with thousands of three and four‑bedroom homes using a lot of showers, laundry and dishwasher cycles. That makes choosing the right hot water system size important, as hot water energy use can be a big share of total household consumption. Local installers are seeing strong interest in heat pump vs solar hot water comparisons, as people weigh up upfront hot water system price against long‑term savings. Brands like Rheem, Rinnai, Sanden and Thermann are common in Smithfield, with options ranging from rheem solar hot water and rinnai solar hot water to high‑performance sanden heat pump units and modern electric storage systems.
To give you a feel for potential savings from a hot water upgrade in Smithfield, here are some typical annual bill reductions many households can achieve:
• Old electric to heat pump hot water system: save around $400–$800 per year. • Gas to heat pump hot water system: save roughly $300–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation with rooftop solar: save around $250–$500 per year.
Over time, these savings help offset the hot water system cost or heat pump hot water price. When you factor in a solar hot water price supported by rebates, or an electric hot water system rebate, the payback can be surprisingly quick.
Smithfield has already seen 426 efficient hot water systems installed, including heat pump hot water installation and solar hot water installation projects. Installations peaked around 2009–2011, when more than 200 systems went in over just a few years, and there has been a steady trickle of new systems since 2020 as interest in electrification and lower running costs returns. Each new heat pump or solar hot water tank replacement represents another household cutting bills and moving away from gas hot water towards an all‑electric home.
