Hot water systems in Throssell

Around Throssell and the 6401 district, more locals are rethinking their hot water system and moving away from old gas or power‑hungry electric units. With an average household size of 2.4 people and most homes being separate houses, long showers, dishwashers and laundries all add up. At the same time, energy costs keep creeping higher, so upgrading to an energy efficient hot water system is becoming the logical next step for many families and retirees across the area.

Throssell is blessed with plenty of sunshine. The local solar data shows mean daily solar exposure of about 19.4 MJ/m², which is roughly 5.4 kWh of sun energy per square metre per day over the year. That strong solar resource means both a solar hot water system and a heat pump hot water system can perform really well here, especially when paired with rooftop solar. For households on modest median incomes, getting more value from every kilowatt‑hour makes a real difference, and the annual hot water energy savings from upgrading can easily reach hundreds of dollars a year.

Across postcode 6401 there are 3,531 dwellings, with 1,088 owned outright and 944 still under mortgage, so there is a big base of owner‑occupiers who can benefit from an efficient hot water upgrade. Many homes are still on older gas or resistive electric hot water, which are expensive to run compared with a modern heat pump hot water system or well‑designed solar hot water heating system. Brands like Rheem and Rinnai are popular for both solar and electric hot water installation, while Sanden and Thermann are often chosen for premium heat pump hot water installation in WA.

In Throssell, efficient hot water installations are already well underway. There have been 848 efficient hot water systems installed in the 6401 area, combining heat pump and solar hot water installation. Install numbers climbed strongly from the mid‑2000s, peaking around 2008–2011, and have stayed steady in recent years, with solid activity through 2020–2024. That steady trend shows growing local interest in electrification, lower running costs and choosing the most efficient hot water system rather than just replacing like‑for‑like when an old unit fails.

For a typical Throssell home, hot water can be one of the biggest energy users. Swapping to an energy efficient hot water system can trim a big chunk off your bills. As a guide, average annual bill savings might look like this:

• Old electric hot water system to quality heat pump hot water system: $450–$900 per year. • Gas storage to heat pump hot water: $350–$750 per year. • Gas storage to solar hot water system: $300–$700 per year. • Old electric to modern electric hot water system with good rooftop solar: $250–$600 per year.

When locals compare heat pump vs solar hot water, it often comes down to roof space, budget and how much daytime solar they export. A heat pump hot water system, especially a premium model like a Sanden heat pump, can be one of the best heat pump hot water system options for all‑electric homes, using off‑peak tariffs or solar power to keep running costs very low. A quality solar hot water heating system from brands such as Rheem solar hot water, Rinnai solar hot water or Chromagen solar hot water can also deliver excellent savings, especially with the strong Throssell sun. For many households, solar hot water vs electric hot water is no contest once long‑term running costs are factored in.

Hot water repair and hot water installation decisions are often made in a rush when a tank fails, but it pays to pause and look at the full hot water system price, including running costs over 10–15 years. While a basic electric hot water installation might have the lowest upfront hot water system cost, the ongoing bills are usually much higher than a heat pump or solar option. Heat pump hot water price or cost has fallen in recent years, and with rebates, the gap to a standard electric hot water system rebate‑assisted unit can be smaller than many people expect. Likewise, solar hot water price or cost can be brought down with incentives, making a rheem solar hot water or chromagen solar hot water system more accessible.

Recent installs in Throssell also include solar hot water tank replacement jobs where older systems have been upgraded to more efficient models, as well as electric hot water repair jobs that turned into full heat pump conversions. Local installers are seeing more questions about electric hot water vs gas hot water and solar hot water vs electric hot water, as people look to cut emissions, future‑proof against gas price rises and move towards all‑electric homes powered by rooftop solar.

Hot Water Rebates, Tariffs & Savings

Across WA, including Throssell, there is strong interest in replacing old gas or electric units with efficient options like heat pumps, modern electric hot water systems and solar hot water. Homeowners can usually access Federal incentives through Small‑scale Technology Certificates (STCs), which effectively act as an upfront discount on eligible solar hot water systems and heat pump hot water systems. On top of that, state‑based programs and retailer offers can create a practical solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in some schemes, reducing the upfront cost significantly.

For many Throssell households, these hot water rebate WA incentives can cut the installed price by a substantial percentage and shorten the payback period to just a few years, especially when combined with rooftop solar. Using timers or smart controls to run a heat pump during the middle of the day can boost savings further by soaking up excess solar instead of exporting it for a low feed‑in tariff. Over the life of the unit, it is common for a well‑chosen system to save thousands of dollars compared with an old gas or electric system, which is why many locals now see efficient hot water as one of the best hot water system Australia upgrades they can make.

If you live in Throssell or the wider 6401 area and your current unit is older, noisy or running up big bills, now is a good time to check whether your home is ready for a hot water upgrade. Whether you are moving from gas to a heat pump, considering a new solar hot water system, or looking at a smarter electric hot water installation that works with your solar, choosing experienced hot water installers matters. With Throssell’s strong solar exposure and growing focus on sustainability, an efficient hot water system can trim your bills, cut emissions and future‑proof your home.
