Hot water systems in Westerway
Across Westerway and the wider 7140 area, more households are rethinking their old gas and electric hot water system and switching to efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With an average household size of around 2.4 people and more than 4,500 occupied dwellings, there is steady hot water demand here, from busy families to older residents wanting reliable, low‑maintenance hot water without bill shock.
The climate around Westerway is well suited to efficient hot water. Local solar data shows mean daily solar exposure of about 13.8 MJ/m², which is roughly 3.8 kWh of solar energy per square metre per day over the year. That is plenty for a well‑designed solar hot water heating system to work effectively, and it also supports efficient heat pump hot water performance, especially when paired with rooftop solar. With many homes owned outright or with a mortgage, upgrading from older gas or off‑peak electric units to an energy efficient hot water system is a logical next step to cut running costs and improve comfort.
In 7140, most homes are separate houses, often with three bedrooms, so a typical family‑sized hot water installation is a 250–315 litre tank for an electric hot water installation or heat pump hot water installation, and a similar or slightly larger tank for a solar hot water installation. Hot water can easily account for a quarter of household energy use, so choosing the most efficient hot water system for your situation really matters. Local installers are seeing more interest in brands like Rheem heat pump hot water and Rheem solar hot water, as well as premium systems such as Sanden heat pump units and Rinnai solar hot water, which are popular with households wanting the best heat pump hot water system or the most efficient hot water system available in Australia.
Typical annual bill savings in Westerway for an average family can look like:
• Old electric to heat pump hot water system: save around $400–$800 per year • Gas to heat pump hot water: save roughly $300–$700 per year • Gas to solar hot water system: save around $250–$600 per year • Old electric to modern electric hot water with solar PV: save roughly $250–$500 per year
Over time, these savings help offset the hot water system price, whether you are looking at a heat pump hot water price, a solar hot water price or a straightforward electric hot water system cost.
Recent data shows 123 efficient hot water systems, mainly heat pump and solar hot water installations, have already been installed across the 7140 postcode. Installations picked up strongly between 2008 and 2012, with peak years in 2009 and 2011, when locals really started to embrace electrification and lower running costs. Although recorded installations have been quieter since 2020, the interest in energy efficient hot water and hot water repair work remains strong, especially as more residents add solar and look at heat pump vs solar hot water and solar hot water vs electric hot water when replacing old systems.
Hot Water Rebates, Tariffs & Savings
For Westerway households, there is growing interest in replacing old gas or ageing electric units with efficient options such as heat pumps, modern electric hot water or a solar hot water system TAS‑wide. Australian Government incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount. On top of this, Tasmanian hot water rebate TAS programs and occasional electric hot water system rebate offers can further reduce the heat pump hot water price or solar hot water price, sometimes cutting the system cost by a substantial percentage. When you factor in bill savings of a few hundred dollars a year, the payback period on a quality Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or Chromagen solar hot water system can be shortened significantly, especially if you use timers or solar diversion to run the system when your PV is generating. These incentives make it easier to choose an all‑electric, energy efficient hot water system and move away from gas hot water for good.
