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 Perillup and the 6324 area, 300 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 Perillup's climate delivering an average of 4.6 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 Perillup

Across Perillup and the wider 6324 district, more locals are rethinking how they heat their water. With power prices biting and many homes still on older gas or electric units, upgrading to a modern hot water system – whether that is a heat pump hot water system, solar hot water system or efficient electric hot water system – is becoming the logical next step. In a rural area where most of the 1,358 dwellings are separate houses and the average household size sits around 2.4 people, hot water demand is steady all year, so any efficiency gain adds up quickly.

Perillup is actually very well suited to efficient hot water. The local climate data shows mean daily solar exposure of about 16.5 MJ/m², which is roughly 4.6 kWh of sunlight energy per square metre per day over the year. That strong solar resource supports both a solar hot water heating system on the roof and a heat pump hot water system drawing warmth from the air, helping them run more efficiently than an older gas or resistive electric unit. With many homes owned outright or with a mortgage, and a median household income that suggests people are careful but able to invest in smart upgrades, shifting from gas to an energy efficient hot water system can deliver meaningful annual hot water energy savings in Perillup.

Around the 6324 postcode, efficient hot water systems – especially heat pumps and solar hot water – are already gaining traction. There have been about 300 efficient hot water installations recorded locally, with steady growth from the early 2000s and noticeable peaks around 2008–2011 when incentives were strong. Recent years still show consistent heat pump hot water installation and solar hot water installation activity, reflecting a growing interest in electrification, lower running costs and getting more value from rooftop solar. Many properties already running solar power are now looking at solar hot water vs electric hot water, or heat pump vs solar hot water, to decide the best fit.

When it comes to brands, Perillup households tend to look for reliability and local backup. Systems like Rheem solar hot water and Rheem heat pump hot water are popular for their long track record, while Rinnai solar hot water and Chromagen solar hot water are common choices for people wanting a proven solar hot water tank replacement. Premium heat pump options such as Sanden heat pump units are often chosen by those chasing the most efficient hot water system and very low running costs. For many, the best hot water system Australia can offer is the one that balances upfront hot water system price or cost with durability, efficiency and easy hot water repair support.

To give you a feel for potential savings in Perillup’s climate, here are some typical annual bill reductions when you combine smart tariffs, timers and, where available, rooftop solar:

• Old electric hot water system to a quality heat pump hot water system: save roughly $400–$800 per year. • Gas storage to heat pump hot water: save around $300–$700 per year, plus avoid future gas price rises. • Gas storage to roof-mounted solar hot water system with electric boost: save about $250–$600 per year. • Old electric to efficient modern electric hot water installation, timed to run on solar: save roughly $200–$450 per year.

In practice, the exact heat pump hot water price or cost, or solar hot water price or cost, will depend on system size, brand and whether a solar hot water tank replacement is needed. However, when you factor in lower running costs and fewer hot water repair call-outs compared with very old systems, many Perillup households find the payback surprisingly quick.

Hot Water Rebates, Tariffs & Savings

Across WA, including in Perillup, interest is rising in replacing old gas or electric hot water with efficient options such as heat pump hot water, modern electric hot water or a roof-mounted solar hot water heating system. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that installers can apply as a discount. There are also changing electricity tariffs and, at times, state-based schemes that can work much like an electric hot water system rebate when you choose an approved energy efficient hot water system.

For a typical Perillup family using a standard storage gas or electric unit, shifting to one of the best heat pump hot water system options or a quality solar system can cut hundreds of dollars off bills every year. When you combine rebates, good tariffs and solar-diversion controls that run your electric or heat pump unit when your panels are producing, the payback period can shrink to just a few years. That makes solar hot water vs electric hot water, or electric hot water vs gas hot water, an important conversation for anyone planning to stay in their home long term.

If you live in Perillup and your current unit is ageing, running out of hot water or costing more than it should, now is a good time to check if your place is ready for a hot water upgrade. Whether you are considering a heat pump hot water installation, solar hot water repair and replacement, or a straightforward electric hot water installation, working with experienced hot water installers who understand hot water WA conditions is crucial. With strong local solar exposure and a community that values sustainability, efficient hot water systems can help cut your bills, reduce emissions and future-proof your home.
