Mountain Bay enjoys strong sunshine, with average solar exposure of about 16 MJ/m² per day, or roughly 4.4 kWh/m²/day across the year. That level of sun is ideal for a modern solar hot water system or heat pump hot water system, especially when paired with rooftop solar. Moving from older gas or resistive electric to a heat pump hot water installation, solar hot water installation or even a smarter electric hot water installation can deliver substantial Annual Hot Water Energy Savings for local households, while supporting the shift to all‑electric homes and lower emissions.
Across the 3723 postcode there are more than 1,200 occupied dwellings, many of them three‑ and four‑bedroom separate houses, so hot water demand can be high when family and friends come to stay. Hot water energy use can easily be a quarter of a home’s electricity bill if you are still on an old electric hot water system or gas storage unit. That is why many residents are now comparing heat pump vs solar hot water, looking for the most efficient hot water system that fits their roof space, budget and lifestyle. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are increasingly common options, alongside systems from Thermann and Solahart.
Typical annual bill savings in Mountain Bay can look like this:
• Old electric to heat pump hot water system: save about $400–$800 per year • Gas storage to heat pump hot water: save about $300–$600 per year • Gas storage to solar hot water heating system: save about $250–$550 per year • Old electric to modern electric hot water system with solar: save about $250–$500 per year
Efficient hot water systems are already taking off locally. In the 3723 area there have been 154 efficient hot water installations (heat pump and solar hot water) recorded, with a big spike in 2009 and steady upgrades through the 2010s. That pattern shows growing interest in electrification, lower hot water system running costs and reliable hot water VIC‑wide, particularly among Mountain Bay homeowners keen to future‑proof their properties.
When you are comparing hot water system price or cost, it is worth looking at the full picture, including rebates and long‑term savings. A quality heat pump hot water price or cost might look higher than a basic electric hot water system up front, but rebates and lower bills usually mean a faster payback. Likewise, a rheem solar hot water or chromagen solar hot water unit can have a higher solar hot water price or cost initially, yet deliver excellent savings over time. If your existing solar hot water tank replacement is overdue, it can be the perfect moment to reassess solar hot water vs electric hot water or electric hot water vs gas hot water and choose the best hot water system Australia has to offer for your needs.
Hot Water Rebates, Tariffs & Savings
Mountain Bay homeowners are increasingly replacing old gas or electric units with heat pump hot water, efficient electric hot water and solar hot water systems to cut bills and emissions. Federal incentives, such as Small‑scale Technology Certificates (STCs), help reduce the cost of each solar hot water system or heat pump hot water system. On top of that, Victorian hot water rebate VIC programs can offer a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate on eligible installations, especially when you are replacing gas.
These hot water rebate VIC incentives can effectively trim system cost by a substantial percentage, often turning a premium heat pump into a very affordable upgrade. When you combine rebates with good tariffs, timers or solar‑diversion controls on an energy efficient hot water system, many Mountain Bay homes can save hundreds of dollars per year and cut the payback period dramatically.
If your current unit is older, noisy or struggling to keep up, now is a good time to check whether your Mountain Bay home is ready for a hot water upgrade. Whether you are moving from gas to a heat pump hot water system, looking at a rheem solar hot water or rinnai solar hot water package, or weighing up the best heat pump hot water system for your family, working with experienced hot water installation and hot water repair specialists matters.
