Coolgardie’s sunshine is a real asset. The town enjoys about 19.4 MJ/m² of solar exposure a day over the year – roughly 5.4 kWh/m² per day – which is excellent for both a solar hot water heating system and high‑efficiency heat pump hot water. That strong solar resource helps a solar hot water system or heat pump run efficiently, cutting running costs compared with older gas units or resistive electric tanks. For many homes, annual hot water energy savings can be several hundred dollars, especially when shifting from older systems to an energy efficient hot water system designed for WA conditions.
Across the 6429 postcode there are 307 occupied dwellings, mostly separate houses, and hot water demand is steady but not extreme – ideal for right‑sized systems rather than oversized tanks that waste energy. Brands like Rheem and Rinnai are popular for reliable solar hot water vs electric hot water upgrades, with options such as Rheem solar hot water, Rheem heat pump hot water and Rinnai solar hot water widely used across regional WA. Premium systems like Sanden heat pump units are often chosen by households chasing the most efficient hot water system and the best heat pump hot water system performance, while Chromagen solar hot water solutions appeal to those wanting a robust solar hot water installation with good local support.
When you compare heat pump vs solar hot water, both can slash bills compared with old electric hot water vs gas hot water setups. Typical hot water system price / cost depends on size and brand, but rebates and lower running costs change the equation. As a guide, annual bill savings for Coolgardie homes can look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year. • Gas to heat pump hot water system: save around $250–$600 per year. • Gas to solar hot water installation: save about $200–$550 per year. • Old electric to modern electric hot water installation with rooftop solar: save roughly $250–$600 per year.
Coolgardie has already seen 64 efficient hot water installations (heat pump and solar) recorded in the postcode. Install numbers were modest for many years, then jumped sharply in 2019 with 25 installs in a single year, showing a clear spike in interest in efficient hot water, electrification and lower running costs. More recent years still show steady, if smaller, numbers as homeowners replace ageing systems, including solar hot water tank replacement and solar hot water repair jobs alongside new heat pump hot water installation projects.
Hot Water Rebates, Tariffs & Savings
For hot water WA homeowners, there is growing interest in swapping out old gas or resistive electric units for efficient options. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that reduces the solar hot water price / cost and heat pump hot water price / cost. WA programs and retailer offers can also act like an electric hot water system rebate when you choose an efficient unit. For many Coolgardie households, these hot water rebate WA incentives can cut the installed hot water system price by a substantial percentage and shorten the payback period to just a few years, especially if you also have rooftop solar. Using timers or solar diversion to run an electric hot water system during the middle of the day makes a solar hot water vs electric hot water comparison even more favourable, pushing your home towards an all‑electric, low‑bill future.
If your current unit is older, noisy, running out of hot water or needing frequent hot water repair, it is a good time to look at an upgrade. Whether you are comparing solar hot water vs electric hot water, looking at Chromagen solar hot water or Sanden heat pump options, or simply wanting the best hot water system Australia can offer for your budget, it pays to get local advice.
