With an average household size of around 3.3 people and more than 4,800 occupied dwellings, hot water demand is high – especially for busy families and multi‑generation homes.

Bonnyrigg’s climate is well suited to efficient hot water technology. Nearby Liverpool records an average annual solar exposure of about 16.2 MJ/m² per day, which is roughly 4.5 kWh/m² of sunshine daily. That strong sunlight supports both heat pump hot water and solar hot water heating system performance, especially when paired with rooftop solar.

In 2177, most homes are three‑ and four‑bedroom houses, so a typical hot water installation will be sized for families using plenty of showers, laundry and dishwashing. For many, the most efficient hot water system will be either a quality heat pump hot water system or a well‑designed solar hot water system backed up by efficient electric boosting. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, with options ranging from premium sanden heat pump units to rheem solar hot water and rinnai solar hot water packages, plus reliable Thermann heat pump and electric models.
When comparing heat pump vs solar hot water, both can dramatically cut running costs compared with old electric or gas units. A modern electric hot water installation can also work well when timed to run on your solar, especially with a smart meter or timer. Typical annual bill savings in Bonnyrigg look like:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water heating system: $250–$550 per year • Old electric to modern electric hot water with good solar use: $200–$450 per year

The big growth years were 2009 and 2010, with more than 40 systems between them, and there has been a steady trickle of new systems in the 2020s as more locals focus on electrification and lower running costs. Each new installation helps cut local emissions and reduces reliance on gas hot water.
Hot Water Rebates, Tariffs & Savings
Bonnyrigg homeowners are increasingly interested in replacing old gas or electric units with efficient options like heat pumps, newer electric hot water systems or solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively reducing the upfront hot water system price. On top of that, NSW hot water rebate programs can offer a specific heat pump hot water rebate or solar hot water rebate for qualifying homes, and in some cases an electric hot water system rebate when switching away from gas.
These hot water rebate NSW offers can cut the heat pump hot water price or solar hot water price by a substantial percentage, often turning a three‑ to seven‑year payback into something much shorter, especially if you already have rooftop solar. By using timers or solar diversion, you can run your electric hot water system mostly on free solar energy, making it an energy efficient hot water system that rivals the best hot water system Australia has to offer. Choosing reputable brands such as rheem heat pump hot water, rheem solar hot water, rinnai solar hot water, Thermann or a premium sanden heat pump, and keeping up with hot water repair and servicing, helps ensure reliability for years.
