The 7216 postcode is dominated by separate houses, with more than 1,500 occupied dwellings and a lot of older housing stock that still runs traditional electric hot water or gas storage. Hot water energy use can be one of the biggest chunks of a power bill for a two‑person home, particularly on standard tariffs. That is why more residents are comparing heat pump vs solar hot water and asking which is the most efficient hot water system for their situation. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, with options ranging from rheem solar hot water and rinnai solar hot water systems through to premium sanden heat pump units and high‑efficiency electric storage.
When you look at hot water system price / cost, it is worth weighing up the long‑term savings. Typical bill reductions in Lottah for a well‑sized upgrade can look like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas to heat pump hot water: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water system with solar: $200–$450 per year

Hot Water Rebates, Tariffs & Savings (H2)
For Lottah households still on old gas or an ageing electric hot water system, there has never been a better time to consider an upgrade. Federal incentives like Small‑scale Technology Certificates (STCs) help bring down solar hot water price / cost and heat pump hot water price / cost, while state‑based hot water rebate TAS programs can offer a heat pump hot water rebate, a solar hot water rebate, and sometimes even an electric hot water system rebate for high‑efficiency models. These hot water rebate TAS incentives can effectively cut the upfront cost of a new energy efficient hot water system by a substantial percentage, often trimming payback periods to just a few years, especially if you already have solar.
With a good quality rheem heat pump hot water, sanden heat pump or chromagen solar hot water setup, many Lottah homes can save hundreds of dollars a year. Add a timer or solar diversion so your electric hot water installation runs mainly on surplus solar, and those savings grow. For some, solar hot water vs electric hot water on grid tariffs is no contest once the numbers are crunched, particularly when you factor in solar hot water tank replacement and long warranties. Even where gas is still available, solar hot water vs electric hot water or gas usually comes out ahead over the life of the system.
