Hot water systems in North Coogee
In North Coogee, more homeowners are rethinking their 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 average household size of around 2.3 people and a big mix of separate houses and newer apartments across the 6163 postcode, there is strong demand for reliable, low‑running‑cost hot water that suits everything from family homes to lock‑and‑leave units.
Power prices in WA keep nudging up, so upgrading from an older gas or resistive electric unit to an energy efficient hot water system is a logical next step. The local solar exposure at nearby Woodmans Point averages about 19.3 MJ/m² per day – roughly 5.4 kWh/m² of sunshine daily – which is ideal for a solar hot water heating system or a high‑efficiency heat pump. For many North Coogee households with median weekly family incomes over $2,000, it is less about the upfront hot water system price and more about long‑term savings, comfort and cutting emissions.
Across the 6163 area there are more than 21,000 occupied dwellings, with a healthy split between homes owned with a mortgage and rented properties. That means lots of older gas and electric hot water still in place, but also a clear trend towards the most efficient hot water system you can reasonably fit on site. Many locals are comparing heat pump vs solar hot water, or looking at solar hot water vs electric hot water paired with rooftop PV, to decide what will work best for their building type and roof space.
When you look at system sizes and savings, it is easy to see why. A typical family upgrading their hot water installation from an old electric storage unit to a quality heat pump hot water system such as a Sanden heat pump or Rheem heat pump hot water can slash usage by up to two‑thirds. Others prefer a roof‑mounted solar hot water installation using brands like Rheem solar hot water, Rinnai solar hot water or Chromagen solar hot water to take advantage of that strong coastal sun. For apartments or smaller homes, a compact electric hot water installation controlled by timers and solar‑diversion can still be a very energy efficient hot water system.
Average annual bill savings will vary, but realistic ranges in North Coogee look like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas to heat pump hot water system: $250–$600 per year • Gas to solar hot water system: $200–$550 per year • Old electric to modern electric hot water system with solar PV: $200–$500 per year
In the 6163 postcode there have already been 4,513 efficient hot water installations, combining both heat pump and solar hot water systems. Installations climbed steadily from the early 2000s, peaking around 2008–2010 when rebates were especially strong, and have remained solid ever since, with between about 150 and 220 systems going in most years through the 2010s. While numbers in 2023–2025 are a little lower, they still show consistent interest in electrification, lower running costs and replacing ageing cylinders before they fail. Each new solar hot water tank replacement or heat pump hot water installation adds to a growing base of efficient homes across North Coogee.
Hot Water Rebates, Tariffs & Savings (H2)
All of this is helped along by generous Australian Government incentives and WA hot water rebate programs. Eligible heat pump hot water and solar hot water systems can create Small‑scale Technology Certificates (STCs), which installers often turn into an upfront discount off the hot water system cost. On top of that, WA and federal schemes periodically offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate that can reduce the effective heat pump hot water price or solar hot water price by a substantial percentage. For many North Coogee households, that means the payback period on the best heat pump hot water system or best hot water system Australia has to offer can drop to just a few years, especially if you also have solar PV. Using timers or solar‑diversion controls so your electric hot water system mostly runs on daytime solar can add hundreds of dollars a year in extra savings. For those still on gas, comparing electric hot water vs gas hot water is increasingly tilting towards efficient electric, particularly when you factor in future gas price uncertainty.
If you live in North Coogee and your current unit is older, noisy or struggling to keep up, this is a good time to check whether your home is ready for a hot water upgrade.
