Hot Water System Costs in Tasmania 2026

Tasmania is unique in Australia's hot water market: there is no natural gas reticulation network in Tasmania. This means Tasmanians rely on electricity (from TasNetworks's hydro-powered grid, one of Australia's greenest electricity networks) or LP Gas for their hot water systems. Tasmania's cold winters, particularly in Hobart, highland areas, and the far south, are important considerations for heat pump hot water system selection. This guide covers hot water system costs in Tasmania in 2026.

No Natural Gas in Tasmania

• Tasmania has no natural gas reticulation network; hot water system fuel options are electricity or LPG (bottled or bulk LP Gas); this simplifies the decision: it's electric storage, heat pump, solar hot water with electric booster, or LPG
• Tasmania's electricity grid (TasNetworks distribution; Aurora Energy retailing) is primarily hydro-powered, one of Australia's lowest-emission electricity supplies; electric hot water in Tasmania is genuinely low-carbon

Cold Climate Heat Pump Hot Water in Tasmania

• Hobart and most of Tasmania experience cold winters (Hobart averages 3-4°C overnight in winter, with periods colder in highland areas and the south); standard heat pump hot water systems reduce in efficiency at low temperatures
• Specify a cold climate rated heat pump hot water model for Tasmanian installations; cold climate models maintain acceptable COP (coefficient of performance) down to -10°C or below; brands with cold climate models: Sanden, Reclaim Energy, iStore, Stiebel Eltron

Hot Water System Types and Costs in Tasmania

• Electric storage: Supply and install: $1,100-$2,300; TasNetworks/Aurora Energy off-peak tariff (check current Aurora Energy tariff structure) significantly reduces running costs for electric storage; reliable year-round performance
• LPG storage/continuous flow: Supply and install (including LPG setup): $1,800-$4,000; ongoing LPG supply costs; useful for remote areas without reliable electricity
• Heat pump hot water (cold climate model): Supply and install: $2,800-$6,000 before STC rebates; STC Zone 4 for Hobart; specify cold climate model; excellent long-term energy savings even in Tasmania's winter
• Solar hot water: Supply and install: $3,200-$7,500 before STCs; Tasmania has lower solar irradiance than mainland states; electric booster required for extended overcast periods and winter; STC Zone 4 values are lower than QLD/NSW; heat pump may offer better economics for most Tasmanians

TAS Plumber Licensing

• Consumer, Building and Occupational Services (CBOS) Tasmania licenses plumbers; Certificate of Compliance required for all plumbing work including hot water installation
