Hot water systems in Oaks
Across Oaks and the wider 7303 area, more households are rethinking their old gas and electric hot water system and shifting to energy‑efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With around 1,199 occupied dwellings and an average household size of 2.3 people, most homes here have steady year‑round hot water demand, but median household incomes are modest, so running costs really matter. That is why upgrading an ageing unit can be one of the quickest ways to cut bills. Locally, the annual solar exposure averages about 15.1 MJ/m² per day – roughly 4.2 kWh/m²/day – which is solid for a solar hot water heating system and supports efficient performance from both heat pumps and solar. For many Oaks homeowners, moving from older gas or resistive electric to an energy efficient hot water system is a logical next step in reducing energy use and emissions.
Most homes in Oaks are separate houses, many owned outright or with a mortgage, which makes hot water installation and future upgrades relatively straightforward. Families and older couples alike are looking for the best hot water system Australia can offer for reliability in winter and lower running costs over the long term. A well‑sized solar hot water system or heat pump can supply the bulk of your hot water needs, especially if you already have rooftop solar. When you compare heat pump vs solar hot water, both can deliver big savings over gas, and modern systems are far more efficient than old storage units. Brands like Rheem, Rinnai and Chromagen are common choices for solar hot water installation and solar hot water tank replacement, while premium options such as Sanden heat pump units are popular with households chasing the most efficient hot water system and very low noise.
In the 7303 postcode there have been 43 efficient hot water installations recorded, including both solar and heat pump hot water installation. Install numbers grew steadily from the mid‑2000s, peaking around 2008–2013 with multiple systems going in each year, and there has been a steady trickle of new installs through to 2024. This shows a clear local interest in electrification, lower running costs and moving away from gas hot water. As more homes add solar PV, we are seeing stronger demand for solar hot water vs electric hot water comparisons, as well as questions about electric hot water vs gas hot water in an all‑electric home.
For a typical Oaks household, the right upgrade can trim a noticeable chunk off annual bills. As a rough guide, many homes see:
• Old electric to heat pump hot water system: $350–$700 per year off bills. • Gas storage to heat pump: $250–$600 per year. • Gas storage to solar hot water system: $250–$550 per year. • Old electric to modern electric hot water installation with rooftop solar: $200–$450 per year.
Of course, every home is different and hot water system price / cost will depend on size, brand and installation complexity. Heat pump hot water price / cost is often higher upfront than a basic electric, but much lower to run. Likewise, solar hot water price / cost can be offset by strong rebates and low operating costs. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that lowers the upfront cost at the point of sale. In Tasmania, additional hot water rebate TAS programs and electric hot water system rebate offers may be available from state schemes or retailers, further improving payback. With discounts that can knock a substantial percentage off the system cost, many Oaks homes can see payback periods drop to just a few years, especially when using timers or solar diversion to run an electric or rheem heat pump hot water unit during solar‑rich hours.
If your existing unit is leaking, unreliable or more than 10–12 years old, it is a good time to compare options like rheem solar hot water, rinnai solar hot water, chromagen solar hot water or a premium sanden heat pump against a simple solar hot water vs electric hot water replacement. Local hot water repair and solar hot water repair specialists can assess whether a fix is worthwhile or if a new hot water installation will save more in the long run. Choosing the best heat pump hot water system or solar hot water heating system for your household means balancing upfront hot water system price / cost, rebates, roof space, noise, and how you use hot water day to day.
Thinking about a hot water upgrade in Oaks? It is worth checking whether your home is ready to shift from gas or an old electric unit to a modern heat pump hot water system, solar hot water system or efficient electric hot water system. With solid solar exposure, a strong base of owner‑occupied homes and growing interest in sustainability, hot water TAS upgrades can cut your bills, reduce emissions and future‑proof your place.
