Grafton’s climate is ideal for heat pump and solar hot water. The local weather station records mean daily solar exposure of about 18 MJ/m², which is roughly 5 kWh of solar energy per square metre per day. That strong sunlight helps a solar hot water heating system or a quality heat pump hot water installation perform at its best, especially when paired with rooftop solar. With a solid base of owner‑occupied homes and a median household income that makes running costs a real consideration, more families and downsizers are looking at heat pump vs solar hot water and even solar hot water vs electric hot water to see what will work best long term.
In the 2460 postcode, hot water demand is driven by a mix of family homes and older residents, many of whom are home during the day and can take advantage of solar generation. Hot water energy use can account for up to a third of household consumption, so choosing an energy efficient hot water system has a big impact on bills. Local installers commonly fit brands like Rheem, Rinnai, Sanden and Thermann, from rheem solar hot water and rinnai solar hot water through to premium sanden heat pump and rheem heat pump hot water units, depending on budget and hot water system price expectations.
Typical annual bill savings in Grafton look like:
• Replacing an old electric hot water system with a heat pump hot water system: $400–$900 per year • Switching gas to a heat pump hot water system: $300–$700 per year • Switching gas to a solar hot water system: $250–$650 per year • Replacing an old electric unit with a modern electric hot water system plus solar: $300–$700 per year
These ranges depend on tariffs, how much hot water you use and whether you already have rooftop solar.
