Hot water systems in Sunnybrae
In Sunnybrae, more locals are rethinking their old gas and electric hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an older population, smaller average household size of around 1.9 people and many homes owned outright, it makes sense for Sunnybrae homeowners to lock in lower running costs and reliable hot water for the long term. The area enjoys strong sunshine, with average solar exposure of about 18.7 MJ/m² per day (roughly 5.2 kWh/m²), which is ideal for both a heat pump hot water system and a solar hot water heating system to perform well and deliver solid annual hot water energy savings.
Out of roughly 724 occupied dwellings, most are separate houses, which gives plenty of roof and yard space for solar hot water installation or an outdoor heat pump hot water installation. With a median household income of about $731 per week and many residents on fixed incomes, rising energy prices bite, so switching from an older gas or resistive electric hot water system to an energy efficient hot water system is a logical next step. Many households in Sunnybrae already use rooftop solar, and pairing that with a modern electric hot water installation or heat pump can turn daytime sunshine into free showers.
Around the 5422 postcode, efficient hot water upgrades are steadily appearing alongside solar. Average household size is modest, but hot water demand is still a big chunk of total energy use, especially in all‑electric homes. Locals are comparing heat pump vs solar hot water and even solar hot water vs electric hot water to find the most efficient hot water system for their situation.
