Hot Water in Tasmania

Hot water plays a significant role in energy use across Tasmania, where the cool climate and low winter temperatures create one of the highest hot water demand levels in the country. With an average winter temperature of just 6°C and relatively low solar exposure of 4 kWh/m²/day, many traditional solar hot water systems struggle to operate efficiently year-round. As a result, heat pump hot water systems have become the preferred efficient option for Tasmanian households. Modern heat pumps are designed to perform reliably even in sub-zero conditions, making them far more economical than older electric resistance units. Combined with Tasmania's predominantly renewable electricity supply, heat pump systems offer an environmentally friendly and cost-effective way to meet daily hot water needs

When selecting a hot water system in Tasmania, households should consider factors such as system efficiency in cold weather, available rebates, installation conditions, and the long-term energy savings available through modern technologies. Heat pumps provide strong year-round performance and can reduce energy use by two-thirds compared with electric storage systems. While electric resistance units remain common in older homes, many households are upgrading to heat pumps to reduce costs and improve sustainability. Solar hot water can still be viable in regions with good north-facing exposure, but overall adoption remains lower due to the state's cooler climate and shorter winter daylight hours. With more than 255,000 dwellings across Tasmania, choosing an efficient system can make a meaningful difference to comfort, household budgets, and environmental impact
