With an average household size of about 2.3 people and more than 3,300 locals over 65, reliability and running costs really matter. Many homes are owned outright or with a mortgage, which makes investing in an energy efficient hot water system a logical next step to protect budgets and add value. The local climate helps too: Thirlstane enjoys around 15.3 MJ/m² of solar exposure a day on average, or roughly 4.25 kWh/m², which is solid for a solar hot water system or a heat pump hot water system that sips electricity while drawing free heat from the air.
For many locals, swapping an old gas or electric hot water system for a modern heat pump hot water system, solar hot water heating system or efficient electric hot water system is about cutting bills year after year. Hot water can easily be a quarter of a home’s energy use, so upgrading can deliver big wins. In the 7307 postcode there are 4,700‑plus occupied dwellings, mostly separate houses, so there is strong potential for roof and yard space to host a solar hot water installation or an outdoor heat pump hot water installation. Brands like Rheem and Rinnai are popular for both solar and electric hot water installation, while Sanden and EvoHeat style heat pump units are often chosen by households chasing the most efficient hot water system and very low running costs.
Across Thirlstane and surrounds, 135 efficient hot water systems have already been installed, combining heat pump and solar hot water installations. Installations really ramped up from 2009 to 2013, with peak years around 2010 and 2011, and steady activity since then as more people look at heat pump vs solar hot water options when their old tank fails. This trend mirrors the broader push towards electrification, lower power bills and moving away from gas hot water, especially for families and retirees watching every dollar.
For a typical Thirlstane household, realistic annual bill savings from a smart hot water upgrade might look like:
• Old electric to heat pump hot water system: save around $350–$700 per year • Gas to heat pump hot water system: save around $250–$600 per year • Gas to solar hot water system: save around $250–$550 per year • Old electric to modern electric hot water system with rooftop solar: save around $200–$500 per year
Local homes with existing solar often find a solar hot water vs electric hot water comparison stacks up well when the tank and panels are correctly sized. Others prefer a compact heat pump unit, such as a Sanden heat pump or Rheem heat pump hot water, which can be programmed to run during the middle of the day when solar output is highest. For some properties, a quality rheem solar hot water or rinnai solar hot water setup, or a chromagen solar hot water style system, offers the right balance of upfront solar hot water price / cost and long‑term savings. Where roofs are shaded or space is tight, a carefully sized electric hot water installation can still be very efficient when paired with solar and smart timers.
When comparing the best hot water system Australia has to offer for your home, it is worth looking closely at heat pump hot water price / cost against solar hot water price / cost, as well as how each option fits your roof, yard and family size. A good installer will walk you through electric hot water vs gas hot water running costs, hot water system price / cost, likely maintenance and options for hot water repair or solar hot water repair down the track. If your existing solar hot water tank replacement is due, it can be a perfect time to reassess whether a new solar hot water system, a best heat pump hot water system, or a modern energy efficient hot water system will give you the lowest lifetime cost.
In Thirlstane, hot water tas homeowners can also tap into generous incentives. Federal Small‑scale Technology Certificates (STCs) reduce the upfront cost of eligible solar hot water and heat pump units, effectively acting as a built‑in solar hot water rebate or heat pump hot water rebate at the point of sale. On top of that, state‑based hot water rebate tas programs and electric hot water system rebate offers can further bring down the price, sometimes cutting the installed cost by a substantial percentage. With rebates and good solar design, payback periods can shrink to just a few years, especially if you use timers or solar‑diversion to run your system when your panels are producing the most. Over time, many Thirlstane households see hundreds of dollars per year shaved off their bills simply by upgrading to a more energy efficient hot water system.
