Eldorado’s sunshine makes efficient hot water a logical next step. The town enjoys about 17.1 MJ/m² of solar exposure a day on average – roughly 4.75 kWh/m² per day – which is excellent for both a solar hot water heating system and a heat pump hot water system that sips electricity. Upgrading from older gas or an ageing electric hot water system can slash the annual hot water energy use for Eldorado homeowners, especially for families and the many over‑50s living here who value comfort but want to keep bills sensible.
Across postcode 3746 there have already been 23 efficient hot water installations – a mix of heat pump hot water installation and solar hot water installation – over the past couple of decades. Install numbers picked up around 2007–2011, with small bursts again in 2018, showing steady curiosity about electrification and lower running costs. As more homes add solar power on the roof, pairing it with the most efficient hot water system becomes an obvious way to use that free daytime energy.
For a typical Eldorado household, hot water is one of the biggest energy users. Many homes still run older gas or resistive electric units that cost a lot to run. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are becoming more common for those chasing the best heat pump hot water system or the best hot water system Australia can offer. Others prefer a simple, reliable rheem solar hot water or chromagen solar hot water setup with a solar hot water tank replacement when the old cylinder finally gives up.
When you compare heat pump vs solar hot water, both can dramatically reduce your hot water system price / cost over the life of the unit. A quality heat pump hot water price / cost is often lower upfront than a full solar hot water system, while a solar hot water price / cost can be very attractive if you already have good roof space facing north. Modern electric hot water installation, especially when timed to run on solar, is also far cheaper to run than old electric hot water vs gas hot water options.
Typical annual bill savings in Eldorado look like this:
• Old electric to heat pump: save around $350–$700 per year. • Gas to heat pump: save roughly $250–$600 per year. • Gas to solar hot water: save about $200–$550 per year. • Old electric to modern electric with solar: save around $200–$450 per year.
Those savings are even better when you factor in rebates. Under federal incentives, most efficient systems earn Small‑scale Technology Certificates (STCs), which cut the effective hot water system price / cost at the point of sale. On top of that, the Victorian hot water rebate VIC programs can offer a separate heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when replacing inefficient units. For many Eldorado homeowners, these hot water rebate VIC schemes can reduce the upfront cost by a substantial percentage, shortening the payback period to just a few years.
Using timers or smart controls to run a hot water installation during sunny hours, or adding solar diversion, can turn your set‑up into a truly energy efficient hot water system. That is where solar hot water vs electric hot water powered by rooftop solar becomes an interesting choice. Either way, the goal is the same: reliable hot water VIC wide, lower bills and fewer emissions.
If your system is leaking, running out of hot water or just getting old, it is a good time to weigh up hot water repair versus full replacement.
