What a hot water system costs in Perth
Perth gets among the most sunshine of any capital, which makes solar hot water a genuinely efficient and long-popular choice here, often the obvious option on a sunny roof. Heat pumps also run well in the mild climate. Natural gas is reticulated across much of the city too, so gas storage and continuous-flow units remain common, giving households a real choice of fuel.
Isolation adds a little lead time on some specific units, but hot-water systems are widely stocked. Perth labour sits just below the national average, so the install is competitive. The warm, sunny climate keeps demand moderate and makes the efficient solar and heat-pump options practical, so for many Perth homes the running-cost case for solar or a heat pump is strong, helped by available rebates.
