Hot water systems in Marradong
Across Marradong and the wider 6390 area, more locals are rethinking their hot water system and moving away from older gas and power‑hungry units. With around 587 occupied dwellings, most of them separate houses and an average household size of 2.5 people, families here use a fair bit of hot water for showers, laundry and everyday living. Power prices keep rising, so upgrading to an energy efficient hot water system is becoming a logical next step for many homeowners and farms.
Marradong’s strong sunshine makes it ideal for a solar hot water system or a modern heat pump hot water system. The local weather station records mean daily solar exposure of about 18.4 MJ/m², which works out to roughly 5.1 kWh/m² per day – excellent for a solar hot water heating system and for running a heat pump efficiently. With a solid base of owner‑occupied homes (around 395 owned outright or with a mortgage) and a median household income of about $1,732 a week, many households are well placed to invest in upgrades that cut bills year after year. Swapping from an old electric hot water system or gas storage unit to a heat pump or solar hot water installation can trim a big chunk off annual energy use, especially as hot water is often the second‑largest load in the home.
In Marradong 6390, efficient hot water is already on the move. There have been 249 efficient hot water installations recorded locally – a mix of heat pump hot water installation and solar hot water installation. Install numbers built steadily through the 2000s, peaking in years like 2009 and 2012, and while yearly totals have eased back more recently, the trend shows a long‑term shift towards electrification, lower running costs and moving away from bottled or reticulated gas where possible.
For a typical Marradong family home with three or four bedrooms, a 250–315 L heat pump hot water system or solar hot water tank replacement is usually enough to cover daily demand. Many locals already have rooftop solar, so pairing that with a quality electric hot water installation or heat pump can turn excess daytime solar into free showers. Brands such as Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium options like the Sanden heat pump are common choices when people want the best heat pump hot water system or simply the best hot water system Australia can offer for reliability in country WA conditions.
Average annual bill savings in Marradong for common upgrade paths can look like:
• Old electric to heat pump hot water system: about $350–$700 per year • Gas storage to heat pump: roughly $300–$600 per year • Gas storage to solar hot water system: around $250–$550 per year • Old electric to modern electric hot water system run on solar: about $250–$500 per year
Actual hot water system price or cost will depend on the size, brand and whether you need extra plumbing or switchboard work. Heat pump hot water price or cost is usually higher upfront than a basic electric unit, but the running costs are dramatically lower. Solar hot water price or cost sits somewhere in between, especially if you go for a roof‑mounted chromagen solar hot water or similar system. When you factor in today’s energy prices, the most efficient hot water system is often a heat pump or well‑designed solar hot water vs electric hot water alone, especially if you are comparing electric hot water vs gas hot water over the full life of the system.
For Marradong homeowners, there are also hot water rebate WA options to bring down the upfront cost. The Federal Government’s Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, acting like a point‑of‑sale discount. On top of that, state‑based heat pump hot water rebate and solar hot water rebate programs can further cut the price, and some newer schemes even support efficient electric hot water system rebate offers when replacing old, inefficient gear. Together, these incentives can reduce the system cost by a substantial percentage and shorten payback times to just a few years, especially if you use timers or solar‑diversion controls so your energy efficient hot water system runs mainly on your rooftop solar.
If your current unit is leaking, more than 10 years old, or you are simply sick of high gas or power bills, it is a good time to weigh up heat pump vs solar hot water, or solar hot water vs electric hot water in the context of your roof space, budget and household size.
