West Arnhem’s strong sun makes it ideal for an energy efficient hot water system. Nearby Oenpelli records an average annual solar exposure of about 21.8 MJ/m² per day – roughly 6 kWh/m² of sunshine daily – which is perfect for a solar hot water heating system or a high performance heat pump hot water system. With more than 5,400 occupied private dwellings and a large share of families on modest median household incomes, the potential hot water energy savings each year are especially important for budgets.
In the 0822 area, demand for reliable hot water installation and hot water repair is steady, from separate houses through to community housing and rentals. Many households are comparing electric hot water vs gas hot water and looking at solar hot water vs electric hot water to cut bills and future‑proof their homes. When you factor in the annual hot water energy savings available in West Arnhem, shifting from old systems to the most efficient hot water system you can afford quickly starts to make sense.
For a typical West Arnhem family, hot water can be one of the biggest energy users.
