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 Gray and the 7215 area, 99 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 Gray's climate delivering an average of 3.7 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 Gray
In Gray and the wider 7215 area, more locals are shifting from old gas and ageing electric units to modern, energy efficient hot water systems. With many residents on modest household incomes (median household income is around $931 a week) and an average household size of 2.1 people, keeping running costs under control really matters. A smarter hot water system can quietly trim hundreds of dollars a year off your power bills while making day‑to‑day life more comfortable.
Gray is actually well suited to efficient hot water technology. The local weather station records an annual mean solar exposure of about 13.5 MJ/m² a day – roughly 3.75 kWh/m² – which gives a solid base for a solar hot water system or a heat pump hot water system to perform well, even in Tassie’s cooler months. With a high share of homes owned outright and many older residents, upgrading a tired gas or electric hot water system is a logical next step to future‑proof the home and lock in long‑term savings. Annual hot water energy savings from a good quality energy efficient hot water system in Gray can be significant, especially if you are moving from an old electric storage unit or gas cylinder.
Across the 7215 postcode there are 1,695 occupied private dwellings, mostly separate houses, and hot water can be one of the biggest single loads on the power bill. Many properties still rely on gas or basic electric hot water, but we are seeing steady interest in options like a solar hot water heating system on the roof, a compact heat pump hot water installation in the yard, or a modern electric hot water installation that works hand‑in‑hand with rooftop solar. Brands such as Rheem, Rinnai and Chromagen are common choices for a solar hot water system in Tasmania, while premium heat pump units like Sanden and Rheem heat pump hot water systems are popular with households chasing the most efficient hot water system and very low running costs.
Typical annual bill savings in Gray when you upgrade your hot water installation can look like this:
• Old electric to quality heat pump hot water system: save around $400–$800 per year • Mains gas to heat pump hot water system: save roughly $300–$600 per year • Gas to roof‑mounted solar hot water system: save about $250–$550 per year • Old electric to modern electric hot water system powered by rooftop solar: save around $250–$500 per year
Over time, these savings really add up, especially for families and retirees watching every dollar. When you factor in the hot water system price / cost, many locals find the payback is faster than expected once rebates and bill reductions are included.
Gray already has a track record of efficient hot water upgrades. There have been 99 efficient hot water systems installed in the postcode, including both heat pumps and solar hot water installation jobs. Installations picked up through the late 2000s and early 2010s, with solid years around 2008–2011, another bump in 2015, and ongoing activity right through to 2024. This pattern shows a growing interest in electrification, lower running costs and getting away from volatile gas prices. As more homes add solar, pairing that with an energy efficient hot water system is becoming the obvious move.
Hot Water Rebates, Tariffs & Savings
For Gray homeowners, the numbers look even better once you add incentives. The Australian Government’s Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of that, there are state‑based hot water rebate TAS programs that can apply to a heat pump hot water installation, a solar hot water installation or, in some cases, a high‑efficiency electric hot water system rebate. Together, these hot water rebate TAS offers can effectively knock a substantial percentage off the installed cost.
That means a solar hot water vs electric hot water or heat pump vs solar hot water decision is no longer just about the sticker price. With rebates, typical households in Gray can cut their bills by hundreds of dollars a year and shorten the payback period to just a few years, especially if they are also using rooftop solar and timers or smart controls to run the system during the day. For many, a modern electric hot water system paired with solar is a simple way to move towards an all‑electric home and away from gas. Others prefer the rock‑bottom running costs of the best heat pump hot water system they can afford, or a reliable rheem solar hot water or rinnai solar hot water setup with a roof‑mounted collector and insulated solar hot water tank replacement when the old cylinder fails. If you already have solar, a solar hot water vs electric hot water comparison will often favour either a solar hot water heating system or a well‑sized heat pump that runs on your excess solar power.
Whether you need hot water repair on an older unit, solar hot water repair after years of service, or you are comparing electric hot water vs gas hot water and wondering what the best hot water system Australia has to offer for your situation, it pays to get tailored advice. Every property in Gray is different – from compact flats to larger three‑bedroom family homes – and the right hot water system price / cost balance depends on how much hot water you use, when you use it, and whether you have or plan to install rooftop solar.
If your current unit is getting on in years, running out of hot water or costing a fortune to run, now is a smart time to see if your Gray home is ready for a hot water upgrade. Talk with experienced local hot water installers who understand heat pumps, solar and efficient electric systems, and who can guide you through solar hot water price / cost comparisons, rebates and the latest technology. With Gray’s strong solar resource, growing interest in sustainability and a clear shift away from gas, an energy efficient hot water system can help you cut bills, reduce emissions and future‑proof your home.
