Hot water systems in Horsley

Across Horsley and the wider 2530 area, more households are swapping old gas and electric units for an energy efficient hot water system that keeps bills down and showers steaming. With an average household size of around 2.7 people and more than 12,600 occupied dwellings, reliable hot water is a must – but so is keeping running costs under control when the median mortgage sits near $2,000 a month. That is why interest in options like a heat pump hot water system, solar hot water system and modern electric hot water system is growing fast.

Horsley’s climate is well suited to efficient hot water. The local Dapto Bowling Club weather station records mean daily solar exposure of about 15.7 MJ/m², which is roughly 4.4 kWh per square metre per day. That strong sunlight supports both heat pump hot water and a solar hot water heating system, especially when paired with rooftop solar. For many Horsley homeowners who already have solar, upgrading from an older gas or electric hot water system is the logical next step, with annual hot water energy savings often reaching hundreds of dollars a year.

Most homes in 2530 are separate houses, and a large share are owned with a mortgage or owned outright, so long term savings really matter. Hot water can be one of the biggest energy users in the home, and switching to the most efficient hot water system can noticeably cut your overall electricity use. Locally, we are seeing strong uptake of heat pump hot water installation and solar hot water installation, as families look for a future proof, all electric home and move away from gas hot water.

In Horsley 2530 there have already been around 1,300 efficient hot water systems installed, combining both heat pump and solar hot water. Installations surged around 2008–2010, with a peak of about 338 systems in 2009 and 230 in 2010, driven by early rebates. After a quieter period, recent years show steady interest, with more than 50 systems in 2021 and ongoing installations through to 2024 and 2025. This trend reflects a clear shift toward electrification, lower running costs and reduced emissions for local households.

When you are comparing heat pump vs solar hot water, or even solar hot water vs electric hot water, it helps to look at real bill savings. Typical annual savings in Horsley can look like:

• Replacing an old electric hot water system with a quality heat pump hot water system: about $400–$800 per year. • Swapping gas hot water to a heat pump: around $300–$700 per year. • Moving from gas hot water to a solar hot water system: roughly $300–$600 per year. • Upgrading an old electric unit to a modern electric hot water system powered by rooftop solar: often $300–$700 per year, depending on usage.

Brands like Rheem heat pump hot water and Rheem solar hot water are popular locally, along with Rinnai solar hot water, Sanden heat pump and Thermann options. Many Horsley homeowners ask which is the best hot water system Australia has to offer for their situation; in practice, the best heat pump hot water system or solar package for you will depend on roof space, family size and whether you want the absolute lowest running costs or the lowest upfront hot water system price.

Hot water repair and solar hot water repair are also important considerations. Ageing systems can become unreliable and expensive to run, so sometimes a hot water tank replacement or full solar hot water tank replacement is more cost effective than ongoing hot water repair bills. A tailored hot water installation – whether heat pump hot water installation, solar hot water installation or electric hot water installation – can be designed to match your current and future needs.
