Hot water systems in Yarrambat
In Yarrambat, more households are rethinking their old gas and electric hot water system and moving to efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With mostly separate houses, an average household size of 3.1 people and solid family incomes, many 3091 homeowners are looking for smarter ways to cut running costs without sacrificing comfort.
Local solar exposure helps a lot. The nearby Plenty weather station records an average of about 14.9 MJ/m² of sunshine a day, which is roughly 4.1 kWh/m² of energy. That is plenty of free energy to support a solar hot water heating system or an efficient heat pump hot water installation, especially if you already have rooftop solar. For a typical Yarrambat family using hot water every morning and evening, upgrading from an older gas or resistive electric unit can deliver substantial annual hot water energy savings.
Across the 521 dwellings in the postcode, most are owned outright or with a mortgage, which makes long‑term investments like an energy efficient hot water system more attractive. Many homes are larger, with three, four or more bedrooms, so hot water demand is higher than in inner‑city units. That is where choosing the most efficient hot water system for your needs really matters, whether that is a quality rheem heat pump hot water unit, a rheem solar hot water package, rinnai solar hot water, a sanden heat pump, or a chromagen solar hot water solution.
In Yarrambat 3091, efficient hot water upgrades are already underway. There have been 67 efficient systems installed locally, combining heat pump and solar hot water installation projects. Installations spiked around 2009 and 2011, with steady activity through the 2010s and new systems still going in as recently as 2024. This trend reflects a growing interest in electrification, getting off gas, and lowering bills with options like solar hot water vs electric hot water and electric hot water vs gas hot water.
When you compare heat pump vs solar hot water, both can dramatically cut running costs compared with an old electric hot water system. A heat pump hot water price or cost is often similar to a quality solar hot water price or cost once rebates are applied, and both can work well with existing rooftop solar. For some homes, a modern electric hot water installation paired with solar and a timer can also be a cost‑effective step, especially if you are planning a future battery.
Typical bill savings in Yarrambat might look like this:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water system: save around $250–$600 per year. • Gas to solar hot water system: save around $200–$550 per year. • Old electric to modern electric hot water with solar: save around $200–$500 per year.
These numbers will vary with tariffs, family size and how you use hot water, but they give a realistic guide when you are weighing up hot water system price or cost against long‑term savings.
