What a hot water system costs in Adelaide
Adelaide has both natural gas reticulated across much of the city and plenty of sun, so households genuinely choose between gas continuous-flow units, solar hot water and heat pumps, with all three practical here. The city's lower labour rates make the install among the more affordable of the mainland capitals.
Hard water in parts of the Adelaide supply can shorten the life of some systems through scale build-up, a local factor worth raising with the installer when choosing a unit. The warm, dry climate keeps demand moderate and makes solar efficient. Rebates for efficient systems can offset the upfront cost. For an Adelaide home, the combination of fuel choice, strong sun and low labour makes it one of the better-value capitals for hot water.
