Hot water systems in Prestons
Across Prestons and the wider 2170 area, more households are swapping old gas and ageing electric units for an energy efficient hot water system that keeps bills down without sacrificing comfort. With an average household size of about 2.9 people and more than 36,000 occupied dwellings, hot water is a big slice of local energy use. Many families are juggling mortgages around $2,165 a month and weekly household incomes of about $1,566, so reducing running costs with a modern heat pump hot water system, solar hot water system or efficient electric hot water system simply makes sense.
Prestons is well suited to efficient hot water upgrades. The local climate delivers around 16.2 MJ/m² of solar exposure a day – roughly 4.5 kWh/m² – which is ideal for both a solar hot water heating system and high performance heat pump hot water. That sunshine helps drive strong Annual Hot Water Energy Savings when you move from an older gas or resistive electric hot water system to options like Rheem heat pump hot water, Sanden heat pump units or roof‑mounted brands such as Rheem solar hot water and Rinnai solar hot water. For many families and multi‑generational households, upgrading is the logical next step after installing rooftop solar.
In the 2170 postcode, most homes are separate houses or townhouses, with a good number of larger three and four bedroom properties, so hot water demand can be high. That is where choosing the best hot water system Australia offers for your situation really matters. A well‑sized heat pump hot water installation or solar hot water installation can cover the bulk of your daily needs, while a modern electric hot water installation paired with rooftop solar suits units and smaller homes. Locally, you will see a mix of Sanden heat pump systems for premium efficiency, Rheem and Rinnai solar hot water, and Chromagen solar hot water or similar for value‑conscious households.
Typical annual savings in Prestons from an efficient hot water upgrade can look like:
• Old electric to heat pump: save around $400–$800 per year on bills. • Gas to heat pump: save roughly $300–$700 per year. • Gas to solar hot water: save about $250–$600 per year. • Old electric to modern electric with solar: save around $250–$500 per year.
These ranges depend on usage, tariffs and how much solar you export or divert to your hot water system. Many locals are also weighing up heat pump vs solar hot water, and solar hot water vs electric hot water, to find the most efficient hot water system for their roof space, budget and lifestyle.
Recent data shows 1,299 efficient hot water systems have already been installed in the Prestons 2170 area, combining both solar hot water and heat pump units. Installations jumped sharply around 2009 and 2010, then settled into steady numbers with renewed interest from 2018 onwards as power prices rose and more people looked to electrify their homes. This trend towards energy efficient hot water system choices lines up with the strong take‑up of rooftop solar and a growing desire to move away from gas hot water and volatile gas prices.
Hot Water Rebates, Tariffs & Savings
Around Prestons NSW, more homeowners are asking whether to choose a heat pump hot water system, solar hot water system or a newer electric hot water system when their old unit fails. Part of that interest is driven by generous incentives. Australian Federal Government Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump hot water installations, effectively acting as an upfront discount. On top of that, NSW hot water rebate programs and schemes can support heat pump hot water rebate offers, solar hot water rebate options and, in some cases, an electric hot water system rebate when you are replacing old, inefficient units. Combined, these hot water rebate NSW incentives can cut the effective heat pump hot water price / cost or solar hot water price / cost by a substantial percentage.
When you factor in lower running costs – often hundreds of dollars a year off bills – and smart controls like timers or solar‑diversion, the payback period on a quality system can shrink dramatically. For many Prestons households, especially those already running rooftop solar, a carefully chosen heat pump or solar hot water tank replacement is one of the quickest ways to reduce bills, cut emissions and future‑proof an all‑electric home.
If your current unit is more than 10 years old, running on gas, or your power bills keep creeping up, now is a good time to see if your Prestons home is ready for a hot water upgrade.
