Hot Water Systems in Old Plains

Hot water systems in Old Plains

In Old Plains, more locals are swapping old gas and ageing electric units for an energy efficient hot water system that actually suits the way they live. With most homes being separate houses and an average household size of around 2.4 people, families, farmers and retirees alike need a hot water system that is reliable, affordable to run and ready for those busy mornings. With a median household income of about $1,600 a week and plenty of homes owned outright, upgrading now can lock in lower running costs for years.

The Old Plains climate is made for efficient hot water. The area enjoys around 19.6 MJ/m² of solar exposure a day on average – roughly 5.4 kWh/m² per 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 deliver free energy most of the year, while a modern heat pump hot water installation uses the warmth in the air to slash power use compared with an older electric hot water system. Many households here are already running rooftop solar, so pairing it with an energy efficient hot water system is a logical next step.

Across the 6569 postcode there are 109 dwellings, with 40 owned outright and 23 still under mortgage, so long term savings really matter. Hot water can be one of the biggest energy users in the home, especially for families and properties with three or four bedrooms, which are common in Old Plains. Upgrading from an old gas unit or a tired electric storage system to the most efficient hot water system you can afford can make a noticeable dent in quarterly bills, particularly if you compare heat pump vs solar hot water options against what you are paying now.

Typical annual bill savings for Old Plains homes can look like:

• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water: save around $250–$600 per year. • Gas to solar hot water system: save about $300–$650 per year. • Old electric to modern electric hot water installation with solar: save roughly $200–$500 per year.

Brands like Rheem and Rinnai are popular here for both solar hot water installation and efficient electric hot water, with options like Rheem solar hot water, Rheem heat pump hot water and Rinnai solar hot water offering proven reliability. Premium heat pump units such as Sanden heat pump systems are often chosen by households chasing the best heat pump hot water system and the lowest possible running costs. Chromagen solar hot water is another option for those wanting a robust solar hot water tank replacement with strong performance in WA conditions. When comparing solar hot water vs electric hot water, or electric hot water vs gas hot water, the key is matching system size, tariff and controls to your household’s pattern of use.

Old Plains households are already moving in this direction. There have been 27 efficient hot water installations recorded in the 6569 postcode, covering both heat pump and solar hot water systems. While uptake started slowly in the early 2000s, there were noticeable bumps around 2008, 2014, 2018 and again in 2025, when three systems were installed in a single year. That steady trend shows growing interest in electrification, lower running costs and using local solar resources instead of relying on bottled or mains gas.

Hot Water Rebates, Tariffs & Savings

With power prices rising, it is no surprise more Old Plains residents are eyeing off a hot water upgrade, replacing old gas or electric units with a heat pump hot water system, a modern electric hot water system or a solar hot water heating system. For homeowners in Old Plains, WA, Australian Government Small-scale Technology Certificates (STCs) can reduce the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, WA and national programs at times offer a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate for certain models, which can bring the overall hot water system price / cost down by a substantial percentage.

When you combine rebates with good tariffs and rooftop solar, many households see hundreds of dollars a year off their bills, and the payback period for a new solar hot water system or heat pump can be cut significantly. Using timers or solar-diversion controls to run an electric hot water system or heat pump during the middle of the day helps soak up excess solar and makes your hot water wa setup even more efficient. These options are making hot water rebate wa offers very attractive for anyone planning to stay in their home for a few more years.
