Karnup’s climate is ideal for efficient hot water. Nearby Hopelands records an average annual solar exposure of about 19 MJ/m² a day – roughly 5.3 kWh/m² – which is excellent for both a solar hot water heating system and high‑performance heat pump hot water.

Across the suburb, hot water demand is driven by busy family households, and hot water use can be one of the biggest chunks of overall electricity consumption. Many properties still run gas or older electric storage units, so the potential for community hot water energy savings is significant. Newer brands like Sanden heat pump units and Rheem heat pump hot water systems are popular for all‑electric homes, while roof‑mounted Rheem solar hot water and Rinnai solar hot water options suit Karnup’s sun‑drenched roofs. For some properties, a straightforward electric hot water installation using a modern, well‑insulated tank timed to run on solar can also be a smart move.
Typical annual bill savings when you upgrade your hot water system in Karnup can look like:
• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas storage to heat pump: save around $250–$500 per year. • Gas storage to solar hot water system: save about $300–$600 per year. • Old electric to new electric hot water system run on rooftop solar: save roughly $250–$500 per year.
These are general ranges; your exact hot water system price / cost and savings will depend on household size, tariffs and how much solar you already have.

Hot Water Rebates, Tariffs & Savings
Around Karnup, more homeowners are asking about heat pump vs solar hot water, solar hot water vs electric hot water and electric hot water vs gas hot water as they plan to replace ageing units. Federal incentives such as Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost and heat pump hot water price / cost, effectively acting as a solar hot water rebate or heat pump hot water rebate for eligible systems. WA programs and retailer offers can also support an electric hot water system rebate or broader hot water rebate wa options for efficient upgrades. When these discounts are applied, it is common for the installed solar hot water price / cost or heat pump hot water cost to drop by a substantial percentage, and payback periods can shrink to just a few years, particularly if you use timers or solar diversion to run the system when your PV array is producing. For many households, that means hundreds of dollars off annual bills while cutting emissions at the same time.
