Local data shows around 120 efficient hot water systems have already been installed in the Mulga Downs area, combining heat pump and solar hot water installations. Installations peaked in 2006 with 49 systems going in, followed by steady activity through 2007 and 2012. After a quiet patch, interest has picked up again with new systems in 2023 and 2025. That trend reflects a renewed focus on electrification, lower running costs and moving away from gas hot water towards options like heat pump vs solar hot water, or solar hot water vs electric hot water backed by solar panels.
For many homes, the choice now comes down to heat pump vs solar hot water. A solar hot water price or cost will typically be higher upfront than a basic electric unit but much lower to run, especially with strong sun. A heat pump hot water price or cost can be similar or a little higher than solar hot water, but it can run efficiently day or night and is often considered the most efficient hot water system overall. There are also situations where a straightforward electric hot water installation still makes sense, particularly when combined with rooftop solar and smart timers.
In WA, homeowners in Mulga Downs can usually tap into Federal incentives such as Small‑scale Technology Certificates (STCs) for eligible heat pump and solar hot water systems, effectively providing a solar hot water rebate or heat pump hot water rebate off the upfront price. State programs and retailer offers may also act as a hot water rebate wa for qualifying households, and there are sometimes electric hot water system rebate options when replacing old, inefficient units. These discounts can cut the hot water system price or cost by a substantial percentage, and when you add in bill savings of hundreds of dollars a year, the payback period can shrink to just a few years. Using timers or solar‑diversion controls to run your energy efficient hot water system when your solar is exporting can further improve savings.
If your current unit is rusting, running out of hot water, or you are weighing up electric hot water vs gas hot water, now is a good time to look at the best hot water system Australia can offer for your situation. Whether you need hot water installation for a new build, hot water repair on an existing system, solar hot water repair, or a solar hot water tank replacement, it pays to talk to experienced local hot water installers in Mulga Downs.
