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 Temma and the 7330 area, 34 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 Temma's climate delivering an average of 3.8 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.

Community Hot Water Statistics - Temma, 7330
Hot Water Demographics - Temma
Based on the Australian Bureau of Statistics 2021 Census (ABS), Temma has around 2,919 private dwellings, home to approximately 5,951 people. With an average household size of 2.4 people, and around 50 litres of hot water used per person each day in Australia, Temma households use approximately 120 litres of hot water daily, equating to a massive 0.4 million litres of hot water used across the suburb every single day.
Other census insights reinforce Temma's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Temma community is home to 489 couple families with children and 140 one-parent families, meaning a large proportion of households face substantial hot water demand. With 818 homes owned with a mortgage and 879 owned outright, many residents also have the homeownership and growing equity that make switching to efficient hot water systems a practical way to lower expenses.
Temma is converting hot water demand to efficient systems faster than many peers, with 1.2% of dwellings already upgraded.
Hot water systems in Temma
In Temma, more locals are rethinking their old gas and electric hot water system and moving to energy‑efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of around 2.4 people and a big share of homes owned outright or with a mortgage, hot water is a major running cost for families and retirees across the 7330 area. Swapping out a tired unit before it fails is a simple way to cut bills, reduce maintenance and make everyday life more comfortable.
Temma’s coastal climate is better for efficient hot water than many people realise. The local weather station records mean daily solar exposure of about 13.8 MJ/m², which works out to roughly 3.8 kWh/m² per day over the year. That steady sunlight supports both a solar hot water system or solar hot water heating system on the roof, and a high‑efficiency heat pump hot water system that runs on off‑peak power. For many homes, hot water can be one of the biggest energy users, so upgrading from old gas or resistive electric can deliver substantial Annual Hot Water Energy Savings.
Across the 7330 postcode there are 2,470 occupied private dwellings, mostly separate houses with three bedrooms, so typical Temma homes have enough roof space and yard room for a hot water installation without drama. Many properties still rely on older gas or electric hot water, but interest in the most efficient hot water system options is growing as power prices rise and more residents add rooftop solar. Brands like Rheem and Rinnai remain popular for both solar and efficient electric hot water, while premium systems such as Sanden heat pump units are gaining a reputation as some of the best heat pump hot water system choices in Australia for cold‑climate performance.
For a rough guide to savings, here are typical annual bill reductions Temma households might see when upgrading their hot water system:
• Old electric to heat pump hot water installation: $400–$800 per year • Gas to heat pump hot water: $300–$700 per year • Gas to solar hot water installation: $300–$650 per year • Old electric to modern electric hot water installation with rooftop solar: $250–$500 per year
Local data shows 34 efficient hot water systems (heat pump and solar hot water installations) have been recorded in the 7330 area, with a noticeable spike around 2011 when 11 systems went in, followed by steady smaller numbers through 2014–2017. That pattern reflects growing local interest in electrification, lower running costs and replacing gas with an energy efficient hot water system that pairs well with solar. As systems age, we are also seeing more solar hot water repair work, solar hot water tank replacement and hot water repair call‑outs where owners decide it is smarter to upgrade than patch an old unit.
When weighing up heat pump vs solar hot water, it often comes down to roof space, budget and whether you already have solar PV. A rheem solar hot water or rinnai solar hot water system can be excellent if you have good north‑facing roof and want to maximise free solar energy. A sanden heat pump or rheem heat pump hot water unit is ideal if you prefer flexible placement on the ground, high efficiency in cooler Tasmanian weather and simple electric controls. Some households still choose a quality electric hot water system as a straightforward replacement, especially when combined with rooftop solar and timers or diverters that run the unit during the day. In many cases, solar hot water vs electric hot water is not an either/or decision, but about designing the best hot water system Australia can offer for your particular home and tariff.
Hot Water Rebates, Tariffs & Savings
Around Temma, more homeowners are looking to move away from old gas hot water and install an energy efficient hot water system, whether that is a heat pump, a modern electric hot water system or a solar hot water heating system. Australian Federal Government incentives such as Small‑scale Technology Certificates (STCs) can reduce the effective solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, Tasmanian and other state‑based programs periodically offer a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate for eligible households, which can bring the upfront hot water system price / cost down by a substantial percentage. For many Temma homes, the combination of rebates and lower running costs means payback can be just a few years, especially if you use timers or solar diversion to run your hot water TAS system when your panels are producing. Over the life of the unit, it is common to save many hundreds, even thousands, of dollars compared with sticking with gas or an old resistive electric unit.
If you are in Temma and your current system is older, unreliable or running on gas, now is a good time to check whether a hot water upgrade makes sense. Talking to experienced local installers who specialise in heat pump hot water installation, solar hot water repair, solar hot water installation, electric hot water installation and general hot water repair can help you compare electric hot water vs gas hot water, heat pump vs solar hot water and solar hot water vs electric hot water for your property. With strong solar exposure, a community that cares about costs and comfort, and solid hot water rebate TAS options available, upgrading to an efficient system is a practical way to cut bills, lower emissions and future‑proof your home.
