With most of the 215 dwellings being separate houses and many owned outright or with a mortgage, homeowners here are well placed to plan a smart hot water upgrade rather than waiting for a breakdown. An average household size of around 2.3 people means steady hot water demand, and with power prices rising, it makes sense to look closely at the running cost of your current hot water system.
Wunghnu’s sunshine is a big advantage. The nearby Numurkah weather station records an average annual solar exposure of about 17.7 MJ/m² per day, which is roughly 4.9 kWh/m² of solar energy daily. That is ideal for both a modern solar hot water system and a quality heat pump hot water system, especially if you already have rooftop solar. Upgrading from older gas or a tired electric hot water system to an efficient heat pump or solar hot water heating system can deliver substantial annual hot water energy savings for Wunghnu households.
Across the 3635 postcode, there have been 31 efficient hot water installations (mainly heat pump and solar hot water) recorded, with a big spike around 2009–2010 and renewed growth from 2017 onwards, including multiple installs in 2024 and 2025. This trend shows growing local interest in electrification, lower running costs and the most efficient hot water system options. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for low running costs, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are often chosen where roof orientation is good. For all‑electric homes, a modern electric hot water system with timers or solar diversion can still be an energy efficient hot water system compared with old resistive tanks.
In a typical Wunghnu home, hot water can be one of the biggest energy users. Rough guide savings when you upgrade include:
• Old electric to heat pump hot water installation: save around $350–$700 per year on bills. • Gas to heat pump vs solar hot water: often $250–$600 per year, depending on usage. • Gas to solar hot water installation: save about $200–$500 per year. • Old electric to new electric hot water installation with solar: around $200–$450 per year.
Actual hot water system price or cost will vary with size, brand and whether you need a solar hot water tank replacement or a completely new hot water installation, but many households are surprised how quickly the upgrade pays for itself.
For Wunghnu VIC residents, there is strong support from both the Federal Government and the Victorian Government for efficient hot water upgrades. Small‑scale Technology Certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate, cutting the upfront heat pump hot water price or cost and solar hot water price or cost. On top of that, various state programs can offer a hot water rebate vic for eligible heat pump hot water installation, solar hot water installation, and sometimes even a modern electric hot water installation. Combined, these incentives can reduce the system cost by a substantial percentage and shorten payback to just a few years, especially if you use timers or solar‑diversion controls to run your hot water system when your solar is generating. There are also schemes that support an electric hot water system rebate when replacing gas, making electric hot water vs gas hot water far more attractive for Wunghnu households.
If you are comparing heat pump vs solar hot water or weighing up solar hot water vs electric hot water, it often comes down to roof space, budget and how you use energy. Many locals find that choosing one of the best heat pump hot water system options on the market, such as a Sanden heat pump or a premium Rheem heat pump hot water unit, delivers low running costs with minimal roof work. Others prefer the simplicity of a reliable rheem solar hot water or rinnai solar hot water setup as part of a broader solar hot water heating system. Whatever you choose, working with experienced installers ensures correct sizing, efficient pipework and long‑term reliability, including prompt hot water repair and solar hot water repair support when needed.
