Hot water systems in Rosebery
Across Rosebery and the 0832 postcode, more homeowners are swapping old gas and electric units for an energy efficient hot water system that actually suits the Top End climate. With an average household size of about 2.9 people and more than 4,500 separate houses plus hundreds of apartments, daily hot water demand is high – and so are power bills. That makes choosing the right hot water system a smart way to ease the squeeze on a typical household income of around $2,350 a week.
Rosebery’s strong sunshine is a huge advantage. The area enjoys around 21.2 MJ/m² of solar exposure a day on average – roughly 5.9 kWh/m² – which is excellent for both a solar hot water system and a modern heat pump hot water system. In this climate, a solar hot water heating system or high quality heat pump can deliver big annual hot water energy savings compared with an older electric hot water system or gas storage unit. For families paying off a sizeable mortgage and juggling kids’ showers, laundry and dishes, upgrading is a logical next step.
In 0832, most homes are three or four bedroom properties, so hot water demand is steady all year round. Many households already have rooftop solar, which pairs perfectly with a heat pump hot water system or efficient electric hot water system using timers to run when the sun is shining. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular options for those chasing the most efficient hot water system, while Rheem solar hot water and Chromagen solar hot water are well known for reliable solar hot water installation and solar hot water tank replacement. For some homes, a well‑sized electric hot water installation, run on solar power, can be just as cost effective.
Typical savings in Rosebery look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year on bills. • Gas to heat pump: save around $250–$600 per year, with lower emissions. • Gas to solar hot water installation: save about $300–$650 per year, depending on usage. • Old electric to modern electric hot water with solar: save $200–$500 per year.
Over time, the hot water system price or cost is usually outweighed by these savings, especially when you factor in rebates and the rising cost of electricity and gas. A quality heat pump hot water price or cost can look higher up front, but the running costs are much lower. Likewise, a solar hot water price or cost can be offset by using more free solar energy and less grid power. For many households, the best hot water system Australia can offer is the one that matches their roof space, budget and how they use hot water day to day.
Rosebery has already seen 3,163 efficient hot water installations – mainly heat pump and solar – across the postcode. Install numbers climbed steadily from just 10 systems in 2001 to peaks of over 260 systems a year around 2017, and installations have remained strong through to 2024 and 2025. This trend shows growing local interest in electrification, lower running costs and moving from electric hot water vs gas hot water towards cleaner, smarter options. It also means there is now a solid base of experience locally for hot water installation and hot water repair, including solar hot water repair.
Hot Water Rebates, Tariffs & Savings
In Rosebery, more households are comparing heat pump vs solar hot water and even solar hot water vs electric hot water as they look to replace ageing gas or electric units.
