Across 6714, there have been 479 efficient hot water installations recorded – mainly heat pump and solar hot water installation jobs. Installations ramped up through the 2000s, with busy years like 2003, 2007 and 2009, and while numbers have eased off more recently, interest in electrification and efficient hot water is rising again as people compare heat pump vs solar hot water and look at solar hot water vs electric hot water options.

For a typical Karratha family, hot water is one of the biggest single energy loads in the house. Swapping an old unit for the most efficient hot water system you can reasonably afford is often cheaper over the life of the system, even if the upfront hot water system price feels higher.

• Old electric to heat pump hot water installation: save about $400–$800 per year. • Gas to heat pump hot water system: save around $300–$600 per year. • Gas to solar hot water installation: save roughly $250–$550 per year. • Old electric to modern electric hot water installation run on solar PV: save about $300–$700 per year.
These ranges depend on your tariffs, household size and how you use hot water, but they give a fair guide when you are weighing up heat pump hot water price or cost, solar hot water price or cost and the cost of a quality electric hot water installation. If your tank is rusting, your shower is going cold or you are calling for hot water repair more than you would like, it is usually smarter to plan a replacement than wait for a burst cylinder.
Karratha also benefits from a mix of federal and WA hot water rebate options. The Australian Government’s Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price or cost and heat pump hot water price or cost at the point of sale, effectively acting as a discount. On top of that, WA and national programs at times support heat pump hot water rebate offers, solar hot water rebate schemes and, in some cases, an electric hot water system rebate when you switch away from gas. For many households in Karratha WA, these incentives can trim the installed hot water system price by a substantial percentage and shorten the payback period to just a few years, especially if you are also using timers or solar diversion to run your system when your PV is producing.
