With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Detention and the 7321 area, 35 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Detention's climate delivering an average of 3.9 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Detention
Across Detention and the wider 7321 area, more locals are looking at upgrading to an energy efficient hot water system instead of sticking with old, power‑hungry units. With a median household size of around 2.4 people and more than 1,800 occupied dwellings, reliable hot water is a daily essential, but rising energy prices mean many households are rethinking how they heat it. For a community with a median household income of about $1,341 a week and plenty of families and over‑65s, cutting running costs without sacrificing comfort just makes sense.
Detention’s climate is actually well suited to efficient hot water. The nearby Port Latta weather station records an average annual solar exposure of about 14.1 MJ/m² per day, which works out to roughly 3.9 kWh/m² of usable solar energy every day across the year. That is strong support for a solar hot water system or modern heat pump hot water system, especially when paired with rooftop solar. Upgrading from older gas or an ageing electric hot water system to a heat pump or solar hot water heating system can slash the energy used for hot water, which is often the second‑biggest load after heating in Tasmanian homes.
In Detention, most residents live in separate houses, with a high rate of homes owned outright or with a mortgage. That is ideal for investing in long‑term upgrades like a heat pump hot water installation or solar hot water installation. Many households are comparing heat pump vs solar hot water, or even solar hot water vs electric hot water, to find the most efficient hot water system for their needs. Popular brands in Tasmania such as Rheem, Rinnai, Sanden and Thermann offer options across the board, from rheem solar hot water and rinnai solar hot water to rheem heat pump hot water, sanden heat pump units and efficient electric hot water systems.
When you look at hot water system price and long‑term savings, it helps to think in terms of running costs. Typical annual bill savings for Detention homes can look like this:
• Old electric to heat pump hot water system: about $350–$700 per year • Gas to heat pump hot water system: about $250–$600 per year • Gas to solar hot water system: about $300–$650 per year • Old electric to modern electric hot water installation with rooftop solar: about $200–$500 per year
Local installation data shows how Detention is slowly shifting. There have been 35 efficient hot water systems installed in the postcode, combining heat pump and solar hot water installations. Install numbers picked up from 2005, with a noticeable bump around 2010–2013 when several systems went in each year, before tapering off more recently. Even though it is still a small market, that trend reflects growing interest in electrification, lower running costs and moving away from old gas hot water where possible. As more homes add solar, pairing it with an energy efficient hot water system becomes the logical next step.
Hot Water Rebates, Tariffs & Savings
Across Tasmania, including Detention, there is strong interest in replacing tired gas or resistive electric units with a heat pump hot water system, a modern electric hot water system or a solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water heating system and heat pump hot water installation jobs, effectively working as an upfront discount. On top of that, state‑based programs can offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate at times, all helping to bring down the heat pump hot water price or solar hot water price. For many Detention households, these hot water rebate TAS schemes can cut the system cost by a substantial percentage and shorten the payback period to just a few years, especially when combined with solar and smart controls like timers or solar diversion. Switching from electric hot water vs gas hot water to an energy efficient hot water system can easily save hundreds of dollars a year, particularly for medium‑sized families.
If your current unit is rusty, unreliable or just expensive to run, it is a good time to see whether your Detention home is ready for a hot water upgrade.
