Arnold is actually very well suited to efficient hot water upgrades. The local climate delivers strong sunshine, with mean daily solar exposure around 22.3 MJ/m², or roughly 6.2 kWh of solar energy per square metre per day. That level of sun gives a solar hot water heating system or roof-top powered heat pump hot water system plenty to work with, helping you get more free energy from the sky and less from the grid.

In a postcode where many homes are separate houses and there is a mix of public and private rentals alongside owner‑occupied properties, choosing the best hot water system Australia has to offer is as much about running cost as it is about reliability. For a busy family household, hot water can be one of the biggest single energy loads. That is why more locals are weighing up heat pump vs solar hot water, and even solar hot water vs electric hot water backed by rooftop PV.
