Hot water systems in East Fremantle
In East Fremantle, more homeowners are rethinking their old gas and electric hot water systems 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 about 2.5 people and more than 2,900 occupied dwellings, reliable, affordable hot water is a big deal locally. Power prices keep rising, and many East Fremantle families on solid household incomes are now looking for an energy efficient hot water system that cuts running costs without sacrificing comfort.
East Fremantle is perfectly placed for efficient hot water upgrades. The Fremantle weather station records around 19.4 MJ of solar energy a day on average – roughly 5.4 kWh/m²/day – which is excellent for both a solar hot water heating system and a high quality heat pump hot water system. That strong sunshine, combined with good solar uptake across Perth’s inner coastal suburbs, makes it much easier to slash the hot water system price / cost over the life of the unit. For many households, hot water is the second-largest energy user after heating and cooling, so upgrading from an old electric hot water vs gas hot water unit to something more efficient can deliver substantial Annual Hot Water Energy Savings.
Across 6158, there have already been 437 efficient hot water installations, including both heat pump hot water installation and solar hot water installation. Since the early 2000s the numbers have steadily grown, with regular spikes between 2014 and 2021 as more locals chased lower bills and cleaner energy. Recent years still show strong interest, with new systems going in every year as older tanks reach the end of their life and people weigh up heat pump vs solar hot water, or even solar hot water vs electric hot water with rooftop PV.
For a typical East Fremantle home, hot water demand is moderate but constant, especially for families and downsizers in three‑ and four‑bedroom homes. Many are replacing tired gas storage units or basic electric cylinders with brands like Rheem heat pump hot water, Sanden heat pump systems, and roof‑mounted solar from Rheem solar hot water or Chromagen solar hot water. These sit alongside efficient electric options from Rinnai solar hot water compatible systems, giving you plenty of choice when you are comparing the best hot water system Australia wide or trying to pick the best heat pump hot water system for your place.
Average annual bill savings for East Fremantle households are often in these ranges:
• Replacing an old electric hot water system with a quality heat pump hot water system: around $400–$800 per year. • Switching from gas to heat pump hot water: about $300–$700 per year. • Going from gas to a well‑sized solar hot water system: roughly $300–$600 per year. • Upgrading an old electric unit to a modern electric hot water installation and using rooftop solar: about $250–$500 per year.
Over time, those savings more than offset the heat pump hot water price / cost or solar hot water price / cost, especially if you combine a new solar hot water tank replacement with existing PV. When you add in the lower hot water repair bills that often come with newer systems, the payback looks even better.
Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in East Fremantle in replacing old gas or electric units with efficient options. Federal incentives, in the form of Small‑scale Technology Certificates (STCs), reduce the upfront hot water system price / cost for eligible systems such as a solar hot water heating system, rheem solar hot water, rinnai solar hot water or a Sanden heat pump. On top of that, WA and occasional retailer programs can act like a heat pump hot water rebate or electric hot water system rebate, further trimming your out‑of‑pocket expense. These hot water rebate wa offers can effectively cut the system cost by a significant percentage, turning a premium unit into a very affordable upgrade.
For many East Fremantle homes, combining rebates with solar‑friendly tariffs and simple tools like timers or solar diversion means you can heat your water when the sun is shining and your PV is exporting. That can slash payback periods, sometimes down to just a few years, and helps you run the most efficient hot water system possible while keeping hot water repair and running costs low.
If your current unit is more than 10 years old, running out of hot water, or costing a fortune to run, it is a good time to check whether your East Fremantle home is ready for a hot water upgrade. Whether you are moving from gas to a heat pump, considering solar hot water repair and tank replacement, or planning a fresh electric hot water installation to pair with rooftop solar, working with experienced local hot water installers matters. With East Fremantle’s strong solar resource and growing interest in sustainability, an energy efficient hot water system can reduce bills, cut emissions and future‑proof your home.
