Most hot water systems last between 8 and 12 years, depending on the type and maintenance. Electric storage systems typically last 8–10 years, while heat pumps and solar systems can last 15+ years with proper care. SunCity Hot Water recommends annual servicing to extend the life of your system.

The right size depends on your household size. As a guide: 1–2 people need 80–125L, 3–4 people need 160–250L, and 5+ people need 315L or more. Heat pump and solar systems may need a larger tank due to off-peak heating cycles. Our team can assess your needs and recommend the best fit.

For Queensland’s sunny climate, heat pump hot water systems are the most efficient choice — they use up to 75% less electricity than standard electric systems. Solar hot water is also excellent if you have roof space. Gas systems are popular in areas with natural gas supply. Our team will help you choose the right system for your home and budget.

Storage hot water systems heat water and keep it in an insulated tank ready for use. Instantaneous (continuous flow) systems heat water on demand — no tank required. Heat pumps extract heat from the surrounding air to heat water, much like a reverse refrigerator. Solar systems use rooftop collectors to capture the sun’s energy and heat water directly.
