Hot water systems in Nornalup
In Nornalup, more locals are rethinking their old gas and electric hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With a median household size of around 2.3 people and many homes owned outright or with a mortgage, hot water is a big chunk of running costs, especially for families and retirees on fixed incomes. Upgrading to an energy efficient hot water system is a simple way to cut bills without changing your lifestyle.
Nornalup’s sunshine is a big advantage. The local weather station records an average annual solar exposure of about 15.8 MJ/m² per day, which translates to roughly 4.4 kWh/m² of solar energy daily. That is more than enough to support a reliable solar hot water heating system or highly efficient heat pump hot water installation. For homeowners comparing heat pump vs solar hot water, both technologies work well here: solar hot water installation makes the most of clear days, while heat pumps quietly pull heat from the air even in cooler weather, giving you the most efficient hot water system performance all year round.
Across the 6333 postcode, there are 2,362 occupied private dwellings, mostly separate houses with three or four bedrooms, so hot water demand is steady. Older gas units and electric storage tanks can be real energy guzzlers, and hot water energy use can easily be a quarter of a typical household’s electricity. That is why Nornalup households are starting to look at options like Rheem heat pump hot water, Sanden heat pump systems and Rinnai solar hot water as the best heat pump hot water system or solar solution for their needs. Brands such as Rheem solar hot water and Chromagen solar hot water are also common choices when people want a robust solar hot water tank replacement.
Average annual bill savings in Nornalup for a well designed hot water upgrade can be substantial:
• Old electric to heat pump hot water system: save around $400–$800 per year. • Gas to heat pump hot water installation: save roughly $300–$700 per year. • Gas to solar hot water system: save about $250–$600 per year. • Old electric to modern electric hot water installation with rooftop solar: save around $300–$700 per year.
Local data shows this is not just theory. There have already been 738 efficient hot water installations (heat pump and solar hot water) recorded across the 6333 area. Installations climbed strongly through the mid‑2000s, peaking around 2009 with 90 systems in a single year, and have continued at a steady pace with new systems going in every year through to 2025. This long‑term trend reflects growing interest in electrification, lower running costs and cleaner hot water WA wide, and Nornalup is very much part of that shift.
Hot Water Rebates, Tariffs & Savings
For many Nornalup homeowners, the real tipping point is the hot water rebate WA programs and federal incentives now available. Eligible heat pump hot water systems and solar hot water systems can create Small‑scale Technology Certificates (STCs), which effectively act as an upfront discount off your hot water system price or cost. On top of that, state schemes may offer a dedicated heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate for moving away from gas. Together, these incentives can knock a significant percentage off the heat pump hot water price or cost or the solar hot water price or cost, often cutting payback times to just a few years. When you combine rebates with rooftop solar, smart tariffs, timers or solar‑diversion controls, it is possible to shave hundreds of dollars a year off bills and run a truly energy efficient hot water system. For many households, solar hot water vs electric hot water or electric hot water vs gas hot water is now a clear financial decision, not just an environmental one.
