Hot water systems in Elsternwick

Across Elsternwick, more households are moving away from old gas and power‑hungry electric units towards an energy efficient hot water system that actually suits modern living. With an average household size of around 2.3 people and more than 3,200 homes owned outright or with a mortgage, many locals are looking at the next smart upgrade after solar – a better hot water system. Swapping a tired gas or electric hot water system for a heat pump hot water system, solar hot water system or modern electric hot water system can cut running costs and emissions while keeping showers comfortable.

Elsternwick’s climate is well suited to efficient hot water. Nearby Caulfield Racecourse records an average of about 15.1 MJ/m² of solar exposure a day over the year – roughly 4.2 kWh/m²/day – which is plenty of sunshine to support a solar hot water heating system or help a heat pump run efficiently. For many local families, hot water energy use is one of the biggest chunks of their electricity or gas bill, so shifting to the most efficient hot water system is a logical way to bank annual hot water energy savings without changing daily habits. With a mix of separate houses and more than 2,500 flats and apartments, there are options that fit everything from compact courtyards to larger family homes.

In 3185, that average household size of 2.3 people means a typical home suits a small to medium hot water installation, but busy family households and share homes may need larger tanks or faster recovery. Many older properties still have gas storage or ageing electric cylinders, so there is strong interest in comparing heat pump vs solar hot water, or even solar hot water vs electric hot water when rooftop space or body corporate rules are a factor. Brands like Rheem heat pump hot water and Rheem solar hot water are popular for replacements in established homes, while Sanden heat pump and Rinnai solar hot water are often chosen by households chasing the best heat pump hot water system or premium solar hot water installation to pair with an existing PV array.

Typical annual bill savings in Elsternwick can look like:

• Old electric to heat pump hot water system: $450–$900 per year • Gas storage to heat pump hot water system: $300–$700 per year • Gas storage to solar hot water system: $250–$650 per year • Old electric to modern electric hot water installation with good solar: $250–$500 per year

These savings depend on tariffs, usage and how well the system is sized, but they show why locals are paying close attention to hot water system price and long‑term running cost, not just the sticker.

Efficient hot water is not new to Elsternwick. There have already been 144 efficient hot water installations recorded in the postcode, covering both heat pump hot water installation and solar hot water installation.

While installations have levelled out to a steady trickle in recent years, from 2019 through to 2025 there has been a consistent flow of new systems each year, reflecting ongoing interest in electrification, lower running costs and more reliable hot water repair and replacement options as older systems fail.

Hot Water Rebates, Tariffs & Savings

For Elsternwick homeowners, the economics of upgrading are getting better. Federal incentives such as Small‑scale Technology Certificates (STCs) effectively provide an upfront discount on eligible solar hot water systems and heat pump hot water systems, cutting the heat pump hot water price or solar hot water price by a meaningful amount. On top of that, Victoria’s state programs often include a solar hot water rebate or heat pump hot water rebate, and in some cases an electric hot water system rebate when you replace an old, inefficient unit with an approved energy efficient hot water system. Together, these hot water rebate VIC incentives can reduce the installed hot water system cost by a substantial percentage.

For many Elsternwick homes, this means the payback period on a quality system can shrink to just a few years, especially when paired with rooftop solar and smart controls. Using timers or solar‑diversion to run a heat pump during the middle of the day, for example, helps you soak up excess solar and slash the effective heat pump hot water cost per year. With energy prices rising, it is common to see hundreds of dollars a year shaved off bills when moving from electric hot water vs gas hot water to a well‑designed all‑electric setup.

If you live in Elsternwick and your hot water system is ageing, noisy or running up big bills, now is a good time to look at options.
