All You Need To Know

How long should a hot water system last?
Most hot water systems last between 8 and 12 years, depending on the type, brand, usage and how well they’ve been maintained. Gas systems tend to last slightly shorter than electric ones, while solar and heat pump systems may last longer with proper servicing. Regular maintenance—like flushing the tank and checking the anode rod—can help extend the life of the unit. If your system is older than 10 years and starting to have issues, it might be more cost-effective to replace it.
What’s the most energy-efficient hot water system?
Heat pump and solar hot water systems are generally the most energy-efficient, using renewable energy or ambient heat to warm your water. These systems often come with higher upfront costs but can significantly reduce long-term energy bills, especially when paired with timers or solar PV systems. Gas continuous flow systems are also efficient, as they only heat water as needed. The best choice depends on your budget, energy source availability and household water usage patterns.
Why is my hot water suddenly cold or inconsistent?
A sudden drop in water temperature could be caused by several issues—like a faulty thermostat, failed heating element, sediment build-up inside the tank or a gas ignition problem. If your hot water runs out quickly, it may be due to a damaged dip tube or a system that’s no longer keeping up with demand. Inconsistent temperatures are also common in ageing systems. A licensed plumber can diagnose the issue and let you know whether a repair or replacement is the better option.
