Wollangambe’s climate is well suited to efficient hot water. Local solar data shows mean daily solar exposure of about 15.8 MJ/m², which works out to roughly 4.4 kWh of solar energy per square metre per day over the year. That level of sunshine supports both a solar hot water heating system and a high performance heat pump hot water system, especially when paired with rooftop solar. For many households, upgrading from an older gas or resistive electric unit to an energy efficient hot water system is the logical next step after installing solar, with annual hot water energy savings often reaching hundreds of dollars.
Across the 2790 area there are more than 6,000 occupied private dwellings, many owned outright or with a mortgage, which makes long term upgrades like solar hot water installation or heat pump hot water installation particularly attractive. Hot water can account for up to a quarter of household energy use, so choosing the most efficient hot water system you can afford is a smart move. Popular brands in the region include Rheem solar hot water and Rheem heat pump hot water, Rinnai solar hot water and premium options like a Sanden heat pump, all competing for the title of best heat pump hot water system and best hot water system Australia for local conditions.
Typical savings in Wollangambe for a well designed upgrade look like:
• Old electric to heat pump: around $350–$700 a year off bills. • Gas to heat pump: around $250–$600 a year. • Gas to solar hot water: around $200–$550 a year. • Old electric to modern electric hot water with solar: around $200–$500 a year.
In 2790 there have already been 222 efficient hot water systems installed, combining heat pump and solar hot water systems. Installations climbed sharply from the mid‑2000s, peaking between 2009 and 2011 when more than 130 systems went in over just three years. While yearly numbers have eased back since, the steady trickle of new installs through to 2024 shows ongoing interest in electrification, lower running costs and moving towards all‑electric homes in Wollangambe. Many of these households are also using solar hot water repair and hot water repair services to keep existing systems running efficiently rather than defaulting back to gas.
When it comes to hot water system price or cost, the upfront outlay for a heat pump hot water system or solar hot water tank replacement is higher than a basic electric unit, but rebates help close the gap. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water heating system and heat pump systems, and NSW hot water rebate programs can further cut the heat pump hot water price or cost or solar hot water price or cost. There are also electric hot water system rebate options in some programs when you switch from gas, supporting the broader shift to hot water NSW homes that run on clean electricity. Together, these incentives can effectively trim system cost by a substantial percentage and shorten payback periods, especially if you also use timers or solar‑diversion to run your hot water when your PV is generating.
Choosing between heat pump vs solar hot water or solar hot water vs electric hot water will come down to your roof space, budget, and whether you already have solar panels. For shaded sites, a quality heat pump such as a Sanden heat pump can be the most efficient hot water system, while sunnier roofs may favour a Chromagen solar hot water or similar. Either way, the goal is an energy efficient hot water system that slashes bills, reduces emissions and suits the way your household uses hot water.
If you are in Wollangambe and wondering about electric hot water vs gas hot water, or which option is the best fit for your home, it is worth talking to local specialists.
