Hot water systems in Crawley
Across Crawley, more homeowners and investors are quietly upgrading to a more efficient hot water system. With power prices rising and many homes already running rooftop solar, shifting from old gas or ageing electric units to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step. The local numbers back it up: in postcode 6009 there are around 6,274 occupied dwellings, with an average household size of 2.6 people and a strong mix of families and professionals on a healthy median household income of about $2,610 a week. That means plenty of daily hot water demand – and plenty of room for savings.
Crawley’s sunshine is a real asset. The nearby Subiaco station records mean daily solar exposure of about 19.3 MJ/m², which works out to roughly 5.4 kWh of solar energy per square metre per day across the year. That strong solar resource helps both a solar hot water heating system and a quality heat pump hot water system perform efficiently, especially when paired with rooftop PV. For many homes, hot water is the single biggest chunk of electricity use after heating and cooling, so upgrading an old gas or electric hot water system can deliver some of the biggest energy savings in the house.
In 6009 there’s a broad mix of separate houses and over 1,100 flats and apartments, so hot water installation needs to be tailored – from compact heat pump units for smaller courtyards to roof-mounted solar hot water installation on larger family homes. Brands like Rheem and Rinnai are popular for both electric hot water installation and solar hot water tank replacement, while Sanden and Stiebel Eltron are often chosen by locals chasing the best heat pump hot water system and the most efficient hot water system on the market. Many Crawley households compare heat pump vs solar hot water, or solar hot water vs electric hot water, looking for an energy efficient hot water system that suits their roof, budget and tariffs.
Average annual bill savings in Crawley typically look like this: • Old electric to heat pump hot water system: around $350–$700 per year • Gas to heat pump hot water: around $250–$600 per year • Gas to solar hot water system: around $300–$650 per year • Old electric to modern electric hot water with solar diversion: around $200–$450 per year
Local data shows this interest is not just talk. There have been 827 efficient hot water installations – mainly heat pump hot water installation and solar hot water installation – recorded in the 6009 postcode. Installations climbed steadily from the early 2000s, peaking around 2010 with 90 systems in a single year, and have remained consistent since, with 20–45 systems most years. Even recent years, with 26 installs in 2023 and new installs continuing in 2024–2025, show Crawley households are still moving towards electrification, lower running costs and reliable hot water repair and replacement.
Hot Water Rebates, Tariffs & Savings
For Crawley homeowners, one of the big drawcards is the range of hot water rebate options available. Federal incentives like Small-scale Technology Certificates (STCs) effectively discount the upfront solar hot water price / cost and heat pump hot water price / cost when you install eligible systems, including popular models like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water or a premium Sanden heat pump. On top of that, state-based hot water rebate WA programs and electric hot water system rebate offers can further reduce the hot water system price / cost for efficient upgrades. In practice, these solar hot water rebate and heat pump hot water rebate schemes can cut the installed cost by a substantial percentage and shorten payback times to just a few years, particularly if you are diverting surplus solar into your hot water. Many Crawley homes are now choosing an energy efficient hot water system as part of an all-electric home strategy, replacing gas with a modern electric hot water system and using timers or solar-diversion controls to squeeze even more value from their panels.
If you live in Crawley and your current unit is older, noisy, or running on gas, it is a good time to check whether a hot water WA upgrade makes sense. Whether you are weighing up heat pump vs solar hot water, comparing solar hot water vs electric hot water, or just need fast electric hot water installation or solar hot water repair, working with experienced local hot water installers is essential. With strong solar, solid incomes and a clear shift towards sustainability in Crawley, efficient hot water systems can help reduce bills, cut emissions and future-proof your home.
