Hot water systems in Greenough
Around Greenough, more locals are swapping old gas and tired electric units for modern, energy efficient hot water systems. With mostly separate houses spread across postcode 6532 and an average household size of about 2.7 people, hot showers, dishwashers and laundries all add up. Rising energy costs and solid median household incomes mean many families are now looking at a smarter hot water system that cuts bills without sacrificing comfort.
Greenough is well suited to efficient hot water upgrades. The local solar exposure at nearby S Bend averages about 20.4 MJ/m² a day over the year, which is roughly 5.7 kWh of sunshine per square metre, every day. That strong sun makes a solar hot water system or solar hot water heating system a natural fit, and it also boosts the performance of a heat pump hot water system, especially when paired with rooftop solar. With a high level of home ownership (more than 1,800 homes owned outright or with a mortgage) and plenty of families and retirees, upgrading from older gas or resistive electric hot water to an energy efficient hot water system is a logical next step. Many Greenough homeowners are already seeing strong annual hot water energy savings by making the switch.
In a semi-rural area like Greenough, hot water demand tends to be steady across three and four bedroom homes, and hot water can be one of the biggest single energy users in the house. Swapping an old electric hot water system for a modern heat pump hot water system or solar hot water system can dramatically reduce that share. Brands like Rheem, Rinnai, Sanden and Solahart are common in WA, with options ranging from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water, Sanden heat pump units and chromagen solar hot water style systems from other suppliers. Many locals simply want the best hot water system Australia can offer for reliability, while others are specifically chasing the best heat pump hot water system for long term running cost savings.
Typical bill savings in Greenough look like:
• Old electric to heat pump: save around $350–$700 per year • Gas to heat pump: save around $250–$600 per year • Gas to solar hot water: save around $200–$550 per year • Old electric to modern electric with rooftop solar: save around $200–$500 per year
These are estimates only, but they give a feel for how quickly a heat pump hot water installation, solar hot water installation or efficient electric hot water installation can pay for itself, especially when you factor in a hot water rebate WA households can access.
Across Greenough’s 6532 postcode, there have already been 894 efficient hot water installations recorded, combining heat pump and solar hot water systems. Installations really ramped up around 2010 and 2011, when more than 160 systems went in across just two years, and they have stayed steady since, with solid numbers each year through to 2024 and 2025. That steady stream of hot water installation work shows growing local interest in electrification, lower running costs and getting away from volatile gas prices. As more homes add solar, interest in solar hot water vs electric hot water, and heat pump vs solar hot water, continues to grow.
Hot Water Rebates, Tariffs & Savings
For Greenough homeowners, there is strong interest in replacing old gas or basic electric units with efficient options like a heat pump hot water system, a modern electric hot water system or a solar hot water system. Federal incentives such as Small-scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost or heat pump hot water price / cost, and WA-based programs can provide an additional heat pump hot water rebate or solar hot water rebate on eligible systems. In some cases, discounts from combined federal and state support can reduce the effective hot water system price / cost by a substantial percentage. Many households see hundreds of dollars a year off their power bills, and when you combine rebates with rooftop solar and smart timers or solar diversion, the payback period can be cut significantly. For some, that also means shifting from electric hot water vs gas hot water towards an all-electric home running on sunshine, with the most efficient hot water system they can reasonably afford. There are even electric hot water system rebate options in some programs, helping bring the solar hot water price / cost and electric hot water installation cost closer together.
