In a postcode with around 2,470 occupied private dwellings and a solid base of homes owned outright or with a mortgage, many residents are in a good position to invest in long‑term savings. Families and older couples alike are starting to ask whether a heat pump vs solar hot water setup will suit them best, or whether a newer electric hot water system with smart controls is enough. Local installers are seeing more interest in brands such as Rheem heat pump hot water and Sanden heat pump units for cooler climates, along with quality solar options like Rinnai solar hot water and Chromagen solar hot water.
Efficient hot water is already on the move here. There have been 34 efficient hot water installations (heat pump and solar hot water systems) recorded in the 7330 postcode, with a noticeable peak around 2011 when 11 systems went in, and steady solar hot water installation and heat pump hot water installation numbers across 2007–2016. These hot water installation figures show a growing awareness of electrification, lower running costs and the benefits of moving away from gas hot water in Hunter Island TAS.
For a typical family, hot water can be one of the biggest chunks of household energy use. Swapping an old electric hot water system for a heat pump hot water system, or choosing a solar hot water heating system with a well‑sized solar hot water tank replacement, can make a real dent in bills. Average annual savings can look like:
• Old electric to heat pump: $350–$700 per year • Gas to heat pump: $250–$600 per year • Gas to solar hot water: $300–$650 per year • Old electric to modern electric with rooftop solar: $200–$500 per year
Many locals still rely on basic gas or electric units, but the most efficient hot water system options now include premium heat pumps such as Sanden, versatile Rheem solar hot water and Rinnai solar hot water, and robust Chromagen solar hot water packages. When sized correctly, these can be among the best hot water system Australia options for coastal Tasmanian conditions, often rated as the best heat pump hot water system or most efficient solar hot water vs electric hot water choice for long‑term savings.
Recent years have also brought a wave of incentives. Homeowners exploring hot water TAS upgrades can usually access Federal Small‑scale Technology Certificates (STCs) that act like an upfront discount on eligible solar hot water systems and heat pump units. On top of that, state programs can offer a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate for certain efficient models. Together, these hot water rebate TAS schemes can shave a substantial percentage off the hot water system price / cost or heat pump hot water price / cost, and shorten payback times to just a few years. Add smart tariff choices, timers, or solar diversion so your electric hot water installation heats mainly on solar, and the solar hot water price / cost can look even better over the life of the system.
