Hot water systems in Koonya
In Koonya, more homeowners are rethinking their old gas and electric hot water system and moving to energy‑efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With a small, mostly owner‑occupied community (around 65 occupied dwellings and 46 owned outright), many locals are planning long term, looking for the most efficient hot water system to suit an average household size of about 1.8 people and a median age of 61.
Koonya is surprisingly well set up for efficient hot water. The local weather station at Koonya Heights records an average annual solar exposure of about 13.4 MJ/m² per day, which works out to roughly 3.7 kWh of sun energy per square metre per day. That is solid solar exposure for a solar hot water heating system and gives a real boost to heat pump hot water performance too. When you combine that with rising energy costs and modest median household incomes of around $1,010 per week, upgrading from an older gas or resistive electric unit to an energy efficient hot water system can deliver meaningful bill savings every year.
Most homes here are separate houses, many with two or three bedrooms, so hot water demand is steady but not extreme. For many, the question is heat pump vs solar hot water, or even solar hot water vs electric hot water when you already have rooftop solar. Brands like Rheem and Rinnai are well known locally for both solar hot water installation and electric hot water installation, while Sanden and Stiebel Eltron style systems are popular choices when people are chasing the best heat pump hot water system and very low running costs. You will also see systems like Chromagen solar hot water and Rheem solar hot water on established homes where owners have already made the switch.
Across postcode 7187 there have been 3 efficient hot water installations recorded, combining heat pump hot water installation and solar hot water installation. The first systems started appearing around 2010 and 2011, with another in 2023, showing a slow but growing interest in electrification and efficient hot water in Koonya. As power prices climb and more people install solar, it is likely we will see more homes pairing PV with a modern solar hot water system or rheem heat pump hot water to cut bills and emissions.
Typical annual savings for Koonya households can be substantial when you upgrade your hot water installation:
• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water system: save around $300–$600 per year. • Gas to solar hot water system: save roughly $250–$550 per year. • Old electric to modern electric hot water system with rooftop solar: save about $200–$450 per year.
When it comes to hot water repair and replacement, many locals weigh up hot water system price / cost against long‑term savings. A heat pump hot water price / cost can look higher upfront, as can a solar hot water price / cost, but these systems usually pay back over a few years through lower power bills, especially when combined with solar. Solar hot water tank replacement is a common moment to reassess whether to stick with a like‑for‑like system or move to the most efficient hot water system available.
Hot Water Rebates, Tariffs & Savings
There is strong interest in Koonya in replacing old gas or electric units with efficient options, helped along by generous hot water rebate TAS programs. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront discount. On top of that, Tasmanian schemes and retailer offers can provide a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when you are moving away from gas hot water to an all‑electric home.
These hot water rebate TAS incentives can reduce the installed hot water system price / cost by a substantial percentage, cutting payback periods significantly. For many Koonya homes, combining a heat pump or solar hot water system with rooftop solar, smart timers or solar diversion means you can heat most of your water using cheap or free daytime energy. That is where solar hot water vs electric hot water on a standard tariff really starts to favour efficient systems.
