Hot water systems in Crabtree
In Crabtree, more locals are swapping old gas and ageing electric units for an energy efficient hot water system that actually suits Tassie conditions. With an average household size of 2.5 people and more than 3,600 dwellings across the 7109 postcode, reliable hot water is essential for busy families, tradies and older residents alike. Rising power prices and a median household income of around $1,397 a week mean every dollar on the power bill counts, so upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step.
Crabtree’s own solar data shows mean daily solar exposure of about 13 MJ/m², which is roughly 3.6 kWh per square metre per day over the year. That is more than enough sunlight to support a well-designed solar hot water heating system or a high quality heat pump hot water system that draws low-cost energy from the air, even on cooler Tassie days. For many homes that already have rooftop solar, a smart hot water installation is one of the easiest ways to soak up excess solar and cut bills.
Across the 7109 area there are 3,527 separate houses and only a small number of flats, so most homes have the roof space and yard access needed for a solar hot water installation, heat pump hot water installation or electric hot water installation. Many households are still on older gas or resistive electric units, which are often the biggest single energy user in the home. Moving to the most efficient hot water system you can afford can free up hundreds of dollars a year and make it easier to run an all-electric home powered by solar.
Typical annual bill savings in Crabtree look like:
• Old electric to quality heat pump hot water system: $400–$800 per year • Gas storage to heat pump hot water: $300–$700 per year • Gas to roof-mounted solar hot water system: $300–$600 per year • Old electric to modern electric hot water system with rooftop solar: $250–$500 per year
Brands such as Rheem, Rinnai, Sanden and Thermann are common choices locally, with options ranging from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water systems and premium sanden heat pump units.

As systems age, solar hot water repair, solar hot water tank replacement and general hot water repair work are also becoming more common.
Hot Water Rebates, Tariffs & Savings
Crabtree homeowners are increasingly asking about solar hot water vs electric hot water and electric hot water vs gas hot water as they plan their next hot water upgrade. Federal incentives such as Small-scale Technology Certificates (STCs) can reduce the solar hot water price / cost or heat pump hot water price / cost at the point of sale, while state-based hot water rebate TAS programs may add a further discount for eligible heat pump hot water installation or efficient electric hot water installation. Together, these solar hot water rebate and heat pump hot water rebate schemes can knock a substantial percentage off the upfront hot water system price / cost, and in some cases an electric hot water system rebate also applies when you move away from gas.
When you factor in typical savings of hundreds of dollars a year, the payback period on a new energy efficient hot water system can shrink to just a few years, especially if you use timers or solar diversion to run your hot water system when your PV is generating. For many Crabtree households, the real question is not whether to upgrade, but which technology – heat pump vs solar hot water – best fits their roof, budget and usage.
If your current unit is more than 10 years old, running out of hot water or costing a fortune, it is a great time to check whether your Crabtree home is ready for a hot water upgrade. Whether you are moving from gas to an efficient electric hot water system, comparing solar hot water vs electric hot water, or looking at a premium sanden heat pump or rheem solar hot water setup, working with experienced hot water installers is essential. With strong local interest in sustainability and solid solar resources, Crabtree is well placed to cut bills, reduce emissions and future-proof homes with modern hot water TAS solutions.
