With an average household size of around 2.2 people and a big share of homes owned outright or with a mortgage, many locals are looking to cut running costs in retirement or free up cash for the mortgage. Upgrading your hot water system is one of the simplest ways to do that.
The local climate helps. The nearby Araluen Lower weather station records mean daily solar exposure of about 15.7 MJ/m², which is roughly 4.4 kWh/m² per day across the year – plenty of sunshine to drive a solar hot water system or support an efficient heat pump hot water system. In a region with more than 7,800 occupied dwellings and a high proportion of separate houses, the roof space and yard room for a solar hot water heating system or outdoor heat pump unit is usually there. Moving from older gas or resistive electric hot water to a modern energy efficient hot water system can deliver sizeable annual hot water energy savings for Merricumbene households.
In the 2536 postcode, demand for efficient options like heat pump hot water, solar hot water and even smarter electric hot water system designs has been steadily growing. Many homes already have rooftop solar, which makes solar hot water vs electric hot water a timely question: do you use panels to power an electric storage unit, or go for a dedicated solar hot water installation on the roof? Others are weighing up heat pump vs solar hot water to see which is the most efficient hot water system for their block, budget and shade levels.
Recent years have seen strong uptake of brands such as Rheem and Rinnai for both solar and electric hot water installation, along with premium heat pumps like Sanden and efficient options from EvoHeat and Reclaim Energy. These sit alongside systems such as Rheem solar hot water, Rheem heat pump hot water and Rinnai solar hot water, plus Chromagen solar hot water in some homes. Choosing the best hot water system Australia can offer for your situation comes down to matching technology to household size, roof orientation, and whether you plan to go all‑electric.
In the 2536 area, there have already been 1,302 efficient hot water installations, combining heat pump hot water installation and solar hot water installation. Install numbers ramped up sharply around 2009 and 2010, when over 550 systems went in across two years, and there has been a steady trickle every year since, with installations continuing through to 2025. That trend shows growing interest in electrification, lower running costs and hot water nsw solutions that move away from gas hot water towards cleaner options like heat pump hot water and solar hot water vs electric hot water on standard tariffs.
Typical hot water system price or cost will vary, but many locals are seeing worthwhile savings. As a guide, annual bill reductions might look like:
• Old electric to quality heat pump hot water system: around $350–$700 per year • Gas storage to heat pump: roughly $250–$500 per year • Gas storage to roof‑mounted solar hot water system: about $300–$600 per year • Old electric to modern electric hot water system powered by rooftop solar: roughly $250–$550 per year
For many homes, a heat pump hot water price or cost can be offset by lower bills within a few years, especially where daytime solar is available. A solar hot water price or cost can also be attractive when you factor in reduced gas usage and long‑term stability against rising tariffs. When tanks get tired or start leaking, solar hot water tank replacement is a good time to reassess whether a new energy efficient hot water system could be the best heat pump hot water system or solar option for your property.
Hot Water Rebates, Tariffs & Savings
Merricumbene homeowners are increasingly replacing old gas or electric units with efficient options like heat pumps, newer electric hot water systems or a solar hot water heating system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount off the hot water system price or cost. On top of that, the hot water rebate nsw programs can include a heat pump hot water rebate, solar hot water rebate and sometimes an electric hot water system rebate when shifting away from gas.
These rebates can reduce system cost by a substantial percentage and shorten payback times, particularly if you already have rooftop solar or are planning it. Many households see hundreds of dollars per year off bills after a hot water upgrade, and when you combine incentives with smart tariffs, timers or solar‑diversion controls, the payback period can shrink even further.
