Across the 7109 postcode, there are 3,654 occupied private dwellings and a strong mix of families and older residents. That means steady demand for reliable hot water, but also growing interest in cutting running costs. Many households are weighing up heat pump vs solar hot water, or solar hot water vs electric hot water, as they plan to move away from gas and towards all‑electric homes powered by rooftop solar.
In a typical Ranelagh home, hot water is often the second‑biggest energy user after space heating. Swapping an old resistive electric hot water system for a quality heat pump hot water installation can slash that energy use by up to two‑thirds. A solar hot water installation using brands like Rheem solar hot water, Chromagen solar hot water or Rinnai solar hot water can also deliver big savings, especially when paired with existing rooftop solar. Premium units such as Sanden heat pump systems are often chosen by locals chasing the best heat pump hot water system and the most efficient hot water system on the market.
