Across Osterley and the 7140 area, 123 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 Osterley's climate delivering an average of 4.0 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 Osterley
Across Osterley and the wider 7140 area, more homeowners are rethinking their hot water system and shifting away from old, hungry gas and electric units. With average household sizes around 2.4 people and a strong mix of family homes and retirees, reliable and affordable hot water is essential. Power prices keep rising, so moving to an energy efficient hot water system – whether that is a heat pump hot water system, solar hot water system or a modern electric hot water system – is becoming the logical next step.
Osterley’s climate actually helps. The local weather station records mean daily solar exposure of about 14.4 MJ/m², which is roughly 4 kWh/m² per day over the year, with even higher levels in summer. That is plenty of sunshine to support a solar hot water heating system or boost the efficiency of a heat pump hot water system using rooftop solar. With most dwellings being separate houses (over 4,300 in the postcode) and many owned outright or with a mortgage, a large share of households are well placed to invest in long‑term savings from a more efficient hot water installation.
In the 7140 area, hot water demand is typical of regional Tasmania – steady year‑round, with long, hot showers prized in winter. For a two to four‑person home, the most efficient hot water system is usually either a quality heat pump hot water installation or a roof‑mounted solar hot water installation backed by an electric booster. Brands like Sanden heat pump systems, Rheem heat pump hot water, Rheem solar hot water and Rinnai solar hot water are popular options, along with Chromagen solar hot water in some setups. For homes without good roof space, a compact heat pump can still deliver big savings compared with an older electric hot water system.
To give you a feel for potential savings from a hot water upgrade in Osterley, here are some typical annual bill reductions:
• Old electric to heat pump: around $350–$700 per year • Gas to heat pump: around $300–$600 per year • Gas to solar hot water: around $250–$550 per year • Old electric to modern electric with solar: around $200–$450 per year
Over time, these savings add up, especially for families or multi‑bathroom homes. When people compare heat pump vs solar hot water, the choice often comes down to roof space, budget, and how much daytime solar power they have. Either way, both options are usually far cheaper to run than gas or an old electric storage unit, and are often considered among the best hot water system Australia options for cutting bills.
In Osterley and the broader 7140 postcode, there have already been 123 efficient hot water systems installed, combining both heat pump and solar hot water. Installations picked up strongly between 2008 and 2013, with peak years in 2009 and 2011 seeing 17 and 20 systems installed respectively. While the last few years show fewer recorded installs, that earlier wave of activity shows clear local interest in electrification and lower running costs. Many of those systems are now coming up for hot water repair, servicing, or even solar hot water tank replacement, which creates another opportunity to step into the latest technology.
Hot Water Rebates, Tariffs & Savings
Across Tasmania, including Osterley, more households are now looking to replace old gas or electric hot water with efficient options like a heat pump hot water system, newer electric hot water system or solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount off the hot water system price or cost. On top of that, state‑based heat pump hot water rebate programs and electric hot water system rebate offers may be available from time to time, especially when switching away from gas.
When you combine these hot water rebate TAS incentives with a good deal on installation, it is common to see the effective heat pump hot water price or cost, or solar hot water price or cost, drop by a substantial percentage. That means payback periods can shrink to just a few years, particularly if you run the system on a daytime solar tariff or use timers and solar‑diversion to soak up excess rooftop generation. Many households see hundreds of dollars per year off their bills, especially when moving from electric hot water vs gas hot water to something far more efficient.
If your existing unit is due for hot water repair more often, or you are worried about the hot water system price of another like‑for‑like replacement, it is worth comparing solar hot water vs electric hot water and heat pump options side by side. A modern energy efficient hot water system – whether a Rheem solar hot water system, Rinnai solar hot water, Sanden heat pump or similar – can dramatically cut running costs and emissions while still giving you strong, reliable pressure.
