The 6147 postcode, covering Parkwood, Langford and Lynwood and surrounding areas, is home to around 6,062 households. With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Parkwood and the 6147 area, 992 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Parkwood's climate delivering an average of 5.3 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Parkwood
Across Parkwood, more locals are rethinking their old gas and electric hot water system and switching to energy efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With most of the 5,599 dwellings being separate houses and an average household size of 2.6 people, hot showers, dishwashers and washing machines add up, so it makes sense to look for the most efficient hot water system you can. For many Parkwood households paying a median mortgage of around $1,525 a month, trimming energy bills is a smart, low‑stress way to free up cash.
Parkwood is well suited to a solar hot water heating system or heat pump hot water system. The nearby Gosnells weather station records mean daily solar exposure of about 18.9 MJ/m², which is roughly 5.25 kWh per square metre per day over the year, and much higher in summer. That strong sun supports both solar hot water vs electric hot water savings, and helps a heat pump hot water system run efficiently, especially when paired with rooftop solar. With a good mix of families (over 4,000 families in the postcode) and more than 1,800 homes owned outright, upgrading from older gas or resistive electric units to an energy efficient hot water system is a logical next step towards an all‑electric home and lower running costs.
In 6147, hot water demand is driven by thousands of three‑ and four‑bedroom homes, so the right system size really matters. Many homes are moving from electric hot water vs gas hot water towards heat pumps and solar hot water installation that better match family usage. Your hot water energy use can be one of the biggest single loads in the house, so the hot water system price or cost needs to be weighed against long‑term savings. Typical annual bill savings for Parkwood households look like:
• Old electric to heat pump hot water installation: $350–$700 per year • Gas storage to heat pump: $250–$600 per year • Gas storage to solar hot water installation: $250–$550 per year • Old electric to modern electric hot water installation with solar PV: $200–$450 per year
Brands like Rheem heat pump hot water and Rheem solar hot water are common choices for reliable family systems, while Sanden heat pump units are popular for ultra‑efficient performance and quiet operation. Rinnai solar hot water and Chromagen solar hot water systems are also well‑known options when you want a proven solar hot water tank replacement that integrates neatly with your roof layout. Many Parkwood homeowners simply ask for the best hot water system Australia can offer in their budget, or the best heat pump hot water system for their family size.
In Parkwood, there have already been 992 efficient hot water systems installed, combining both heat pump and solar hot water systems. Installations climbed steadily from the early 2000s, peaking around 2010 with 75 installs in a year, and have remained solid with 30–40 systems most years since 2015, including 44 in 2023. That trend shows strong local interest in electrification, cutting gas use and locking in lower, more predictable running costs through smarter hot water WA solutions.
Hot Water Rebates, Tariffs & Savings
The growing number of heat pump hot water and solar hot water systems in Parkwood reflects a clear shift away from older gas and electric units. Homeowners are taking advantage of the Australian Government’s Small‑scale Technology Certificates (STCs), which effectively act as a solar hot water rebate or heat pump hot water rebate at the point of sale, reducing the upfront heat pump hot water price or cost and solar hot water price or cost. In WA, additional state programs and occasional electric hot water system rebate offers can further cut the hot water system price / cost when you choose an approved energy efficient hot water system. For many Parkwood families, that means discounts that can reduce system cost by 20–40% and typical savings of hundreds of dollars a year on bills. When you combine rebates, smart tariffs, and daytime operation using solar, payback periods can shrink to just a few years, especially if you use timers or solar‑diversion controls to maximise self‑consumption.
If you live in Parkwood and your current unit is older, noisy or running up big bills, this is a good time to see whether a heat pump vs solar hot water upgrade, or a modern electric hot water system, is right for you. With strong sun, a community already embracing efficient hot water WA wide, and generous hot water rebate WA incentives, upgrading can cut emissions, reduce bills and future‑proof your home.
