Families and downsizers alike are looking to cut running costs and future‑proof their homes, especially with higher‑than‑average household incomes and rising energy prices. Swapping an older gas or electric hot water system for a heat pump hot water system can slash hot water energy use, delivering solid Annual Hot Water Energy Savings for Deakin homeowners.
In postcode 2600, separate houses still dominate, but there are more than 1,100 flats and apartments as well, so there is no one “best hot water system Australia” for every property. Smaller apartments might lean towards compact electric hot water installation, while larger family homes can take full advantage of a roof‑mounted solar hot water installation or a Sanden heat pump or Rheem heat pump hot water system matched to rooftop solar. Brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices locally for those wanting a reliable solar hot water tank replacement, while premium heat pumps such as Sanden are popular with households chasing the most efficient hot water system possible.
For an average Deakin family home, hot water can be one of the biggest energy users after heating and cooling. Efficient systems help bring those bills back under control. Typical annual bill savings can look like this:
• Old electric to heat pump hot water system: save around $400–$800 per year • Gas to heat pump hot water: save around $300–$600 per year • Gas to solar hot water system: save around $250–$550 per year • Old electric to modern electric hot water with good solar: save around $250–$500 per year
These savings depend on your household size, tariffs and how you use hot water, but they show why heat pump vs solar hot water is now a common conversation in Deakin, along with solar hot water vs electric hot water and electric hot water vs gas hot water when planning an all‑electric home.
Deakin has already seen 134 efficient hot water systems installed – a mix of heat pump hot water installation and solar hot water installation. Installations peaked around 2007–2010, when annual installations reached the mid‑teens, and there has been a steady trickle of upgrades since, including a recent system in 2025. This pattern reflects a growing local interest in electrification, lower running costs and an energy efficient hot water system that suits both long‑term residents and busy professional households.
Hot Water Rebates, Tariffs & Savings
For Deakin homeowners, the numbers look even better once you factor in incentives. Federal Small‑scale Technology Certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate, cutting the upfront solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of this, ACT‑based schemes periodically offer extra support for efficient hot water installation, including electric hot water system rebate options when moving away from gas. Together, these hot water rebate ACT programs can reduce the hot water system price / cost by a substantial percentage and shorten payback to just a few years, especially if you also have solar PV. Using timers or solar‑diversion to run a heat pump during the middle of the day can turn your system into a truly energy efficient hot water system, making the most of Deakin’s sunshine.
If your current unit is older, noisy, or your bills keep creeping up, now is a good time to check whether your Deakin home is ready for a hot water upgrade.
