Hot water systems in The Gardens
In The Gardens, hot water is something you really notice when it goes wrong. With warm, humid weather and busy lifestyles, more locals are shifting from old gas and electric units to an energy efficient hot water system – whether that’s a modern electric hot water system, a solar hot water system or a heat pump hot water system. With an average household size of about 2.4 people and a lot of apartments and townhouses in 0820, the right hot water installation can make a big dent in power bills without taking over your balcony or yard.
The Gardens is perfectly placed for efficient hot water upgrades. The Darwin Botanic Gardens solar data shows mean daily solar exposure of around 21.3 MJ/m² – roughly 5.9 kWh of sun energy per square metre per day – which is excellent for both a solar hot water heating system and for boosting the performance of heat pump hot water. With a median household income over $2,300 a week and many homes either mortgaged or rented, residents are looking for ways to cut running costs without sacrificing comfort. Upgrading from an older gas or electric hot water system to the most efficient hot water system you can reasonably fit is a logical next step, often saving hundreds of dollars a year in hot water energy use.
Across the 0820 postcode, there are thousands of dwellings, from separate houses to high‑rise apartments, so demand for compact, reliable systems is strong. Many households are comparing heat pump vs solar hot water and even solar hot water vs electric hot water to work out what suits their roof space, tariff and budget. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular for efficient upgrades, while Rheem solar hot water and Chromagen solar hot water are well‑known options when people want to maximise that Top End sun. For smaller spaces or strata buildings, a well‑sized electric hot water installation, especially when paired with rooftop solar, can still be an energy efficient hot water system.
Typical annual bill savings in The Gardens for a well‑planned hot water upgrade might look like:
• Old electric to quality heat pump hot water system: save about $350–$700 per year. • Gas to heat pump hot water installation: save roughly $300–$600 per year. • Gas to solar hot water installation: save around $250–$550 per year. • Old electric to modern electric hot water with solar: save about $200–$450 per year.

Hot Water Rebates, Tariffs & Savings
With power prices in the Territory always on people’s minds, it is no surprise that more residents of The Gardens are looking to replace old gas or resistive electric units with a heat pump hot water system, solar hot water system or a more efficient electric hot water system. Australian Government incentives such as Small‑scale Technology Certificates (STCs) can lower the solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of that, Northern Territory hot water rebate nt style programs and occasional electric hot water system rebate offers can further reduce your hot water system price / cost.
A good solar hot water rebate or heat pump hot water rebate can effectively cut the upfront solar hot water price / cost or heat pump hot water price / cost by a substantial percentage. That means shorter payback periods – especially if you also have solar PV and use timers or solar diversion to run your hot water when the sun is shining. For many The Gardens homes, that can mean saving hundreds of dollars a year and getting your money back on an upgrade in just a few years. Add in options like solar hot water tank replacement, hot water repair and solar hot water repair, and it’s easier to keep an existing solar hot water heating system working efficiently for longer.
