Hot water systems in East Perth
In East Perth, hot water is a big part of everyday comfort, whether you are in a riverside apartment or a townhouse near the CBD. With energy prices rising and many locals looking to move away from gas, more households and businesses are upgrading to an energy efficient hot water system – especially heat pump hot water, solar hot water and modern electric hot water options that work well with solar power and off-peak tariffs.
East Perth’s climate is ideal for efficient hot water. The local weather station records an average of about 19.3 MJ/m² of sun per day, which is roughly 5.4 kWh/m² of solar energy daily across the year. That strong solar exposure makes a solar hot water system or solar hot water heating system a smart choice, and also helps a heat pump hot water system run more efficiently in mild conditions. With an average household size of just 1.8 people and a high proportion of apartments (over 4,900 flats and units), many hot water upgrades here focus on compact, wall-mounted or roof-mounted systems that suit strata living while still cutting bills.
There are 7,032 private dwellings in the 6004 postcode, with a mix of owners and renters. Around 1,137 homes are owned with a mortgage and 2,563 are rented through real estate agents, so both investors and owner-occupiers are looking for reliable, low-maintenance options. Swapping an old gas or electric hot water system for a modern heat pump hot water system or solar hot water system is a logical next step, especially when you factor in the annual hot water energy savings that can easily reach hundreds of dollars a year in a sunny suburb like East Perth. For many apartments, a compact electric hot water system paired with rooftop solar can also be a practical, efficient solution.
In East Perth 6004, efficient hot water system sizes are usually matched to smaller households, but demand is still significant because hot water can account for around a quarter of total energy use in some homes. Many buildings are all-electric already, making electric hot water installation or heat pump hot water installation a straightforward upgrade when a unit fails. Where roof space allows, solar hot water installation is popular for townhouses and low-rise blocks, and brands like Rheem, Rinnai and Sanden are common choices. Rheem solar hot water and Rinnai solar hot water systems suit both family homes and small commercial sites, while a Sanden heat pump is often chosen as one of the best heat pump hot water system options for low running costs and quiet operation. For those comparing heat pump vs solar hot water or solar hot water vs electric hot water, local installers can size the system correctly and give realistic guidance on hot water system price / cost, heat pump hot water price / cost and solar hot water price / cost.
For typical upgrade scenarios in East Perth, annual bill savings often fall into these ranges:
• Replacing an old electric hot water system with a quality heat pump hot water system: around $350–$650 per year. • Switching from gas hot water to a heat pump hot water system: roughly $300–$550 per year. • Changing from gas to a well-designed solar hot water system: about $250–$500 per year. • Upgrading an old electric unit to a modern electric hot water system with rooftop solar: roughly $200–$400 per year, depending on usage and solar size.
Across East Perth, there have been 35 efficient hot water installations recorded, combining both heat pump and solar hot water installation projects. Install numbers peaked around 2011 with nine installs in a single year, followed by steady upgrades in 2007, 2009, 2013, 2014, 2015 and more recent activity in 2019, 2021, 2023 and 2024. This gradual but consistent pattern shows growing interest in efficient hot water, electrification and lower running costs as more residents ask about the most efficient hot water system for their apartment or townhouse. When older systems fail, owners are increasingly choosing an energy efficient hot water system rather than like-for-like replacement, and calling in local experts for hot water repair or full hot water installation.
Hot Water Rebates, Tariffs & Savings
Right across East Perth, more people are replacing ageing gas or electric units with efficient options such as heat pumps, modern electric hot water or solar hot water. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that reduces the installed hot water system cost or heat pump hot water price / cost. WA residents can also benefit from state-based schemes and occasional programs that support efficient hot water rebate WA offers, plus attractive electricity tariffs that reward using more power in the middle of the day when solar is strongest. For some households, combined discounts and rebates can cut the system cost by 20–40%, while typical savings from an efficient hot water upgrade can be several hundred dollars per year. When you add timers or solar diversion so your electric hot water installation or rheem heat pump hot water unit runs mainly on rooftop solar, the payback period can shorten dramatically. Even solar hot water repair or solar hot water tank replacement can be worthwhile if it restores performance and avoids higher bills from a temporary electric backup.
If you are in East Perth and your current unit is old, noisy or running up big bills, it is a good time to check whether your home or investment property is ready for a hot water upgrade. Whether you are weighing up electric hot water vs gas hot water, comparing heat pump vs solar hot water, or just want the best hot water system Australia can offer for your situation, working with experienced hot water installers matters. Local specialists in hot water WA can help you compare options like rheem solar hot water, rinnai solar hot water, chromagen solar hot water or a sanden heat pump, estimate your solar hot water price / cost, and decide whether a new solar hot water heating system, heat pump hot water installation or solar hot water repair will deliver the best results.
