Mount William enjoys good solar exposure for Tasmania, with mean daily solar energy of about 14.3 MJ/m² across the year – roughly 4 kWh/m² per day. That level of sunshine gives both heat pump hot water and a solar hot water heating system a solid base to perform well, especially when paired with rooftop solar. For many of the 137 households that own their home outright and the 53 still paying a mortgage, a well-sized hot water installation can deliver strong Annual Hot Water Energy Savings while adding value to the property.
Across postcode 7264 there are 674 dwellings but only 488 residents, meaning plenty of holiday homes and under‑used systems. That makes choosing the most efficient hot water system even more important – you do not want to pay for hot water you barely use. A heat pump hot water installation can be set up with timers to run during solar hours, while a modern electric hot water installation can still work well when matched with rooftop solar and off‑peak tariffs. Brands such as Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular choices for efficient upgrades, and many locals still trust Rheem solar hot water for long‑term reliability.
Typical annual bill savings for Mount William homes can look like this:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water: save roughly $250–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water system with rooftop solar: save around $200–$500 per year.
These ranges will vary with household size and tariffs, but they give a fair idea of what is possible in a small, mostly owner‑occupied community.
Efficient hot water is already arriving in Mount William. Hot water data shows 9 efficient hot water systems installed in the 7264 postcode so far, mostly heat pump and solar hot water installation jobs. There was a clear bump in interest around 2009, with 4 installations in that year alone, and another small wave of hot water installation activity in 2002, 2008, 2011, 2012 and again in 2024.

Hot Water Rebates, Tariffs & Savings
Right across TAS, there is rising interest in replacing old gas or resistive electric hot water with efficient options like a heat pump hot water system, a newer electric hot water system or a solar hot water system. For Mount William homeowners, federal incentives such as Small‑scale Technology Certificates (STCs) can cut the upfront solar hot water price / cost or heat pump hot water price / cost. On top of that, state‑based heat pump hot water rebate and solar hot water rebate programs, plus an electric hot water system rebate in some schemes, can effectively knock a substantial percentage off the installed hot water system price / cost. When you factor in typical savings of hundreds of dollars a year and the ability to run systems on timers or use solar‑diversion, the payback period can shrink dramatically. That is why more people are asking about heat pump vs solar hot water, solar hot water vs electric hot water and which option will be the most energy efficient hot water system for their situation. There are also options for solar hot water tank replacement and solar hot water repair or general hot water repair if you want to extend the life of an existing setup rather than replace it entirely.
If you are in Mount William and your old gas or electric unit is on its last legs, now is a smart time to see whether a heat pump, solar hot water heating system or efficient electric unit is the best heat pump hot water system or overall fit for your home. With strong solar exposure, growing interest in sustainability and generous hot water rebate tas support, switching to an energy efficient hot water system can trim bills, cut emissions and future‑proof your place. Talk with experienced hot water tas installers and local heat pump and solar hot water specialists to compare options like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or Chromagen solar hot water, and get personalised advice on hot water systems Mount William households can rely on for years to come.
