Switching from an old storage gas unit to an energy efficient hot water system is a logical next step, often cutting hot water energy use by more than half.
Around 2530, hot water typically makes up a large slice of household energy use, particularly in family homes with three or four bedrooms and busy bathrooms. That is why the choice of hot water system matters. Brands like Rheem, Rinnai, Sanden and Thermann are common on quotes and in local hot water installation work, offering options from rheem solar hot water and rinnai solar hot water through to rheem heat pump hot water, Sanden heat pump units and efficient electric storage. Many homeowners simply ask for the best hot water system Australia can offer for their budget, but the real question is heat pump vs solar hot water, or solar hot water vs electric hot water, in the context of their roof, tariffs and hot water demand.
Typical annual bill savings in Dombarton look like this:
• Old electric to heat pump hot water installation: $350–$700 per year • Gas storage to heat pump: $250–$600 per year • Gas storage to solar hot water installation: $200–$550 per year • Old electric to modern electric hot water installation with rooftop solar: $200–$450 per year
These ranges depend on usage, tariffs and how much solar you self‑consume, but they give a feel for what is possible.
Efficient hot water is not just theory here. In the 2530 postcode, there have already been about 1,300 efficient hot water systems installed, including both heat pump and solar hot water installation projects. Installations spiked in 2009 and 2010, with more than 560 systems going in across those two years as rebates and early electrification interest took off. While numbers eased after that initial boom, there has been a steady trickle of heat pump hot water installation and solar hot water tank replacement work through the 2010s, with another lift from 2021 onwards as more locals chase lower running costs and look to move away from gas hot water.
For Dombarton homeowners, the appeal goes beyond comfort. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump units, effectively cutting the upfront solar hot water price / cost or heat pump hot water price / cost by a meaningful amount at the point of sale. On top of that, NSW hot water rebate programs and schemes under the NSW Energy Savings Scheme can support heat pump and other energy efficient hot water upgrades, and there are electric hot water system rebate offers in some programs when replacing old, inefficient units. Together, these can shave a substantial percentage off the installed hot water system price / cost.
When you combine rebates with good‑value tariffs, timers or solar‑diversion controllers, many Dombarton households find the payback period on a quality heat pump or solar hot water system drops to just a few years, especially if they already have rooftop solar. Swapping from electric hot water vs gas hot water to a modern energy efficient hot water system can easily save hundreds of dollars a year, while cutting emissions and future‑proofing the home against rising gas prices. For some, a straightforward electric hot water installation controlled to run on solar still makes sense; for others, a high‑end best heat pump hot water system like a Sanden heat pump or premium Rheem or Thermann unit is the most efficient hot water system for their usage profile.
