Hot Water Systems in Coolup
The 6214 postcode, covering Coolup, Birchmont and West Coolup and surrounding areas, is home to around 278 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 Coolup and the 6214 area, 135 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 Coolup's climate delivering an average of 5.2 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 Coolup
In Coolup, more locals are rethinking how they heat their water. With power prices climbing and many homes still running older gas or electric units, upgrading to an energy efficient hot water system is becoming the obvious next step. Most of the 225 occupied dwellings in the 6214 area are separate houses with an average household size of about 2.9 people, so hot water demand is steady year‑round. For a typical family on a median household income of around $1,875 a week, trimming hundreds off annual energy bills makes a real difference.
Coolup’s climate is well suited to efficient hot water. Nearby Pinjarra Farmlands records an average annual solar exposure of about 18.7 MJ/m² per day – roughly 5.2 kWh/m²/day – which is excellent for both a solar hot water system and a heat pump hot water system. That strong sunlight helps a solar hot water heating system pre‑heat your tank and lets a heat pump run efficiently, especially if you already have rooftop solar. Swapping from an old gas or resistive electric hot water system to a modern energy efficient hot water system can slash the energy used for hot water, which is often a quarter of a home’s total use.
In 6214, there are 278 total private dwellings, with many owned outright or with a mortgage, so owners are in a good position to invest in upgrades. Families, retirees and hobby farmers alike are comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to find the most efficient hot water system for their property. Annual hot water energy savings from moving to a quality heat pump hot water system or solar hot water system can be substantial, especially when combined with solar PV.
Across the postcode, 135 efficient hot water systems have already been installed, including both heat pump hot water installation and solar hot water installation projects. Installations grew steadily from the early 2000s, with noticeable jumps around 2007 and again from 2013 onwards. Even in recent years, from 2020 to 2024, there have been consistent installs each year, showing strong local interest in electrification, lower running costs and getting away from gas hot water. Brands like Rheem heat pump hot water, Sanden heat pump systems, Rinnai solar hot water and Chromagen solar hot water are common choices for homeowners wanting the best hot water system Australia can offer for regional conditions.
When it comes to system choice, many Coolup households are weighing an efficient electric hot water system against a full solar hot water system or premium heat pump. A modern electric hot water system paired with rooftop solar and a smart timer can be a very energy efficient hot water system, especially if you are on a favourable off‑peak tariff. Electric hot water installation can also be the simplest path when replacing an old unit in the same spot, and there is growing interest in the electric hot water system rebate options that can help with the upfront hot water system price / cost.
For larger homes with four or more bedrooms – and there are plenty in Coolup – a quality heat pump hot water system can deliver big savings. Typical heat pump hot water price / cost is higher than basic electric, but running costs are far lower. Likewise, a rheem solar hot water or rinnai solar hot water package can be very attractive for properties with good north‑facing roof space. If you already have solar PV, solar hot water vs electric hot water is often decided by how much roof space you want to allocate to panels versus a solar hot water tank replacement or new collector array.
To give you a feel for the numbers, average annual bill savings for Coolup homes might look like:
• Old electric to quality heat pump: $350–$700 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to roof‑mounted solar hot water: $250–$550 per year • Old electric to modern electric with rooftop solar and timer: $200–$450 per year
These are general ranges, but they show why locals are asking more about solar hot water price / cost and heat pump hot water price / cost, not just the sticker price of the unit itself.
Hot Water Rebates, Tariffs & Savings
Around Coolup, the combination of strong sun and rising energy tariffs is pushing many households to consider a hot water upgrade, whether that is a heat pump hot water system, a new electric hot water system or a roof‑mounted solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) effectively act like a solar hot water rebate or heat pump hot water rebate, reducing the upfront cost of eligible systems at the point of sale. On top of this, WA‑based programs and retailer offers can provide additional hot water rebate wa options for efficient systems, helping to bring the hot water system price / cost down to something much closer to a standard replacement.
With the right rebates and discounts, it is common for the effective cost of a heat pump or solar hot water heating system to be cut by a substantial percentage, often turning a payback period of eight to ten years into something more like four to six. For homes with rooftop solar, using timers or solar diversion to run an electric hot water system or heat pump during the middle of the day can push savings even further, often adding hundreds of dollars a year in avoided grid imports. This is where solar hot water vs electric hot water – or heat pump vs solar hot water – becomes a practical question about your roof, budget and how you use energy.
If you live in Coolup and your current unit is old, noisy or running on gas, now is a good time to check whether your place is ready for a hot water upgrade. Whether you are leaning towards a sanden heat pump, a rheem solar hot water package, chromagen solar hot water, or a straightforward electric hot water installation, working with experienced hot water installers who specialise in heat pump hot water installation, solar hot water installation and hot water repair is essential.
