Hot water systems in Topi Topi
Across Topi Topi and the 2423 postcode, more locals are swapping tired gas and old electric units for an energy efficient hot water system that actually suits country living. With most homes here being separate houses and an average household size of around 2.3 people, a right-sized hot water system can make a real dent in power bills. Many households are on fixed incomes, with median household income just over $1,000 a week, so shifting to a more efficient hot water upgrade is a logical next step. The climate helps too: Bungwahl’s average solar exposure is about 16.7 MJ/m² a day – roughly 4.6 kWh/m² – which is excellent for a solar hot water system, a modern electric hot water system running on rooftop solar, or a heat pump hot water system that sips electricity while pulling warmth from the air.
In a community where a high share of homes are owned outright and many residents are over 55, reliability and running costs matter just as much as sustainability. Upgrading from an old gas or resistive electric hot water system to a modern heat pump hot water system or solar hot water heating system can slash the chunk of energy use that hot water takes in the average home. Over a year, that can translate into hundreds of dollars in hot water energy savings for Topi Topi households.
Looking at Topi Topi’s mix of mostly three and four bedroom homes, there is healthy demand for steady, family‑friendly hot water. Many homeowners are comparing heat pump vs solar hot water and even solar hot water vs electric hot water to find the most efficient hot water system for their situation. Brands like Rheem solar hot water and Rheem heat pump hot water are popular for robust, well‑known systems, while Rinnai solar hot water and Sanden heat pump units appeal to those chasing the best heat pump hot water system performance and whisper‑quiet operation. For those with older roof collectors, solar hot water tank replacement can breathe new life into an existing solar hot water installation, while Chromagen solar hot water and similar systems offer solid options for new builds and renovations.
For a typical 2423 household, rough annual savings from a smart hot water installation can look like:
• Old electric to heat pump hot water installation: save around $400–$800 per year on bills. • Gas to heat pump hot water system: save roughly $300–$600 per year. • Gas to solar hot water installation: save about $250–$550 per year. • Old electric to modern electric hot water installation with solar: save around $300–$700 per year.
These ranges depend on usage, tariffs and whether you already have solar PV, but they show why more locals are asking about hot water system price / cost, heat pump hot water price / cost and solar hot water price / cost before their old unit fails. Many are also weighing electric hot water vs gas hot water as they plan for an all‑electric home.
Recent installs in Topi Topi and the wider 2423 area show this shift in action. There have been 244 efficient hot water systems installed so far, combining both heat pump and solar hot water systems. Installations climbed sharply around 2007–2011, with a peak of 49 installs in 2009 and strong years in 2010 and 2011 as rebates and early adopters drove interest. While numbers have eased since, there are still new installs each year through to 2025, reflecting steady local interest in electrification, lower running costs and cleaner hot water NSW households can rely on.
Hot Water Rebates, Tariffs & Savings
Whether you are replacing a failed unit or planning ahead, there is growing interest in Topi Topi in swapping old gas or electric units for options like a high‑efficiency heat pump, a smarter electric hot water system, or a solar hot water system paired with rooftop PV. Australian Federal incentives, such as Small‑scale Technology Certificates (STCs), can reduce the upfront hot water system cost for eligible heat pump and solar hot water systems.
