Across Tacoma South and the 2259 area, 2,648 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 Tacoma South's climate delivering an average of 4.5 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 Tacoma South
Across Tacoma South and the wider 2259 area, more households are shifting from old gas and electric units to an energy efficient hot water system that actually suits modern bills and lifestyles. With an average household size of around 2.7 people and more than 21,000 separate houses in the postcode, hot water demand is steady, and so are power costs. For many families on a median household income of about $1,532 a week, trimming running costs without losing comfort just makes sense.
The local climate helps. Wyong River’s solar data shows mean daily solar exposure of about 16.3 MJ/m², or roughly 4.5 kWh per square metre per day over the year. That level of sunshine is ideal for a solar hot water system or heat pump hot water system, both of which use free energy in the air or sun to slash electricity use. Upgrading from an older gas or resistive electric hot water system to a modern, energy efficient hot water system can cut hot water energy use by well over half, delivering strong annual hot water energy savings for Tacoma South homeowners.
In 2259, most dwellings are stand‑alone homes with enough roof space for a solar hot water heating system or PV, and many are owned outright or with a mortgage, which makes long‑term upgrades more attractive. As energy prices rise, more locals are weighing up heat pump vs solar hot water, comparing the most efficient hot water system options, and looking closely at hot water system price and running cost, not just the upfront quote.
A typical family in Tacoma South might compare an electric hot water system, a solar hot water system with roof collectors, and a premium heat pump hot water system. Brands like Rheem heat pump hot water, Sanden heat pump and EvoHeat are popular for ultra‑efficient heat pumps, while Rheem solar hot water and Rinnai solar hot water are common choices for roof‑mounted solar hot water installation. For those wanting value and reliability, Thermann and Solahart also appear regularly in local quotes. Many households already running rooftop solar are using a modern electric hot water system on timers or diverters so excess solar goes into the tank, improving the solar hot water vs electric hot water equation.
Typical annual bill savings in Tacoma South look like this:
• Old electric to quality heat pump hot water installation: about $450–$900 a year. • Gas storage to heat pump hot water system: roughly $350–$700 a year. • Gas to solar hot water installation (with electric boost): around $300–$650 a year. • Old electric to new electric hot water installation controlled by rooftop solar: often $250–$600 a year.
With time, tanks age and solar hot water tank replacement or hot water repair becomes less appealing than a full hot water installation upgrade. That is reflected in the numbers: there have been 2,648 efficient hot water systems installed in the 2259 postcode, combining both heat pump and solar hot water systems. Installations jumped sharply in 2009 with 579 systems, stayed strong through 2010–2011, and have continued at a steady pace right through to 2024 and 2025. This long‑term trend shows growing interest in electrification, lower running costs and more sustainable hot water NSW‑wide.
When locals compare heat pump hot water price and solar hot water price, they are also looking at rebates. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump units, effectively lowering the hot water system cost at the point of sale. On top of that, state programs can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for replacing old, inefficient units. For many Tacoma South homes, these discounts can cut the installed heat pump hot water cost or solar hot water cost by a substantial percentage, and when combined with rooftop solar and smart timers, payback periods can fall to just a few years.
With rising gas prices, electric hot water vs gas hot water is tilting firmly towards efficient electric options. The best hot water system Australia‑wide for many households is now a high‑efficiency heat pump or well‑designed solar hot water heating system, matched carefully to household size and usage. Locals who want the best heat pump hot water system are often choosing premium brands such as Sanden heat pump or advanced Rheem heat pump hot water units, especially where overnight tariffs and solar work together.
If your current unit is leaking, needing regular hot water repair, or you are worried about bills, it is a good time to look at a hot water upgrade.
