With Caloundra's sunny climate, solar hot water could save you thousands. We compare all options.
Solar Hot Water — Best for Caloundra's Climate
Given that Caloundra enjoys over 280 sunny days per year, solar hot water systems offer the best long-term savings. A quality solar system typically pays for itself in 4–6 years and can reduce water heating bills by 60–80%. Government rebates are also available.
Heat Pump Systems
Heat pumps are a great middle-ground option — they use electricity but are 3x more efficient than conventional electric systems. They work well even on cloudy days, making them a strong contender for Caloundra homes that can't accommodate rooftop solar panels.
Gas Hot Water
Continuous-flow gas systems are popular for larger families. They only heat water on demand, which eliminates standby heat loss. However, with natural gas prices rising in Queensland, running costs are increasing year on year.
Electric Storage Systems
The cheapest to purchase but most expensive to run. These are best as a replacement option when budget is tight, or when paired with a solar PV system to offset electricity costs. PumiFlow recommends electric systems on off-peak tariffs as a budget-friendly option.
