Hot water systems in Manahan
Across Manahan and the wider 2200 area, more households are rethinking their old gas and electric hot water system and switching to efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With an average household size of around three people and more than 14,000 occupied dwellings, reliable, affordable hot water is a big deal for local families and landlords. At the same time, rising energy costs and a median household income of about $1,392 a week mean every dollar saved on bills really counts.
Manahan’s climate is well suited to efficient hot water. Nearby Bankstown Airport records mean daily solar exposure of about 16.3 MJ/m², which is roughly 4.5 kWh/m² of sunlight per day over the year. That strong solar resource helps a solar hot water heating system and a quality heat pump hot water system perform well, especially when paired with rooftop solar. Upgrading from older gas or resistive electric units to an energy efficient hot water system can deliver large annual hot water energy savings for Manahan homeowners, while also setting you up for an all‑electric home in future.
The postcode is a mix of separate houses and a high number of apartments and townhouses, so hot water needs vary from compact electric hot water installation in units through to larger family systems in freestanding homes. Hot water use is a significant chunk of household energy, so choosing the most efficient hot water system makes a noticeable difference to running costs. Brands like Rheem, Rinnai and Chromagen are popular locally for solar hot water installation and solar hot water tank replacement, while premium systems such as Sanden heat pump units are often chosen by households chasing the best heat pump hot water system and the most efficient hot water system available in Australia.
Typical annual bill savings in Manahan for hot water upgrades can look like:
• Old electric to heat pump hot water installation: save roughly $400–$800 per year. • Gas to heat pump hot water: save around $300–$700 per year. • Gas to a solar hot water system: save about $250–$600 per year. • Old electric to modern electric hot water installation using rooftop solar: save roughly $250–$500 per year.
In total, around 278 efficient hot water systems (heat pumps and solar hot water) have been installed across 2200. Installations peaked around 2009–2010, when more than 90 systems went in over two years, and while yearly numbers have eased since, recent installs in 2020–2024 show steady ongoing interest. These heat pump hot water installation and solar hot water repair and replacement jobs reflect a growing local focus on electrification, lower running costs and moving away from gas hot water where possible.
When you compare heat pump vs solar hot water, both can work well in Manahan’s climate. A rheem solar hot water or rinnai solar hot water system suits homes with good roof space and sun, while rheem heat pump hot water or a Sanden heat pump is ideal where roof access is tricky, or you want maximum efficiency from a compact unit. Many homeowners also look at Chromagen solar hot water options as part of a broader solar hot water vs electric hot water decision. For units and smaller homes, a modern electric hot water system can still be an energy efficient hot water system when paired with rooftop PV and smart timers.
Across Australia and in NSW, generous hot water rebate programs are helping Manahan households upgrade sooner. Federal Small‑scale Technology Certificates (STCs) lower the solar hot water price / cost and heat pump hot water price / cost at the point of sale, while state programs can add an extra solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in some schemes. These incentives can reduce the upfront hot water system price / cost by a substantial percentage, cutting payback times dramatically. Combine rebates with solar‑only tariffs, off‑peak rates, timers or solar‑diversion, and many homes can save hundreds of dollars a year on hot water alone. For Manahan residents juggling mortgages of around $1,973 a month and median rents of about $410 a week, those savings are very welcome.
