That is why interest in the best hot water system Australia can offer – including heat pump hot water, solar hot water and high-efficiency electric options – keeps growing.
Typical annual bill savings for Lurnea homes can look like this:
• Replacing an old electric hot water system with a heat pump hot water system: $400–$800 per year • Switching gas hot water to a heat pump: $300–$600 per year • Switching gas hot water to a solar hot water system: $300–$700 per year • Upgrading an old electric unit to a modern electric hot water installation powered by rooftop solar: $250–$500 per year

Even if you are only just starting to think about hot water in NSW, there is growing interest in Lurnea in replacing old gas or electric hot water with efficient options like heat pumps, modern electric hot water or a solar hot water heating system. Australian Government incentives such as Small-scale Technology Certificates (STCs) can reduce the solar hot water price / cost and heat pump hot water price / cost, while state-based schemes may offer a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate for eligible homes. These hot water rebate NSW programs can effectively cut the upfront hot water system price / cost by a substantial percentage, often shaving years off the payback period.
When you combine rebates with rooftop solar, smart tariffs, timers or solar diversion, an energy efficient hot water system can save hundreds of dollars a year and significantly cut emissions. For many households, solar hot water vs electric hot water or heat pump vs solar hot water becomes a question of roof space, budget and how soon you want the system to pay for itself. Either way, solar hot water vs electric hot water is no longer just about comfort – it is about long-term savings and resilience.
If your current unit is leaking, running out of hot water, or you are facing a costly hot water repair, it is worth comparing the solar hot water price / cost and heat pump hot water price / cost against simply replacing like-for-like. In many cases, a heat pump hot water installation or solar hot water tank replacement will pay for itself through lower bills, especially when rebates are applied.
For Lurnea homes, electric hot water vs gas hot water is shifting in favour of efficient electric options. A quality hot water installation using rheem solar hot water, rinnai solar hot water, a sanden heat pump or another trusted brand can deliver reliable performance for years.
