Frequently Asked Questions about Hot Water Systems

The lifespan of your hot water system will depend on how well it’s looked after, and the type of unit it is. For example, continuous flow systems typically last longer than a storage tank as the tank can corrode quickly.

As a rough guide, wall mounted natural gas instantaneous systems can last up to 15-20 years. Storage tanks last around 10-12 years. However, regular maintenance will ensure both last far longer. Just be aware that after a decade, your water heater might not be the most efficient option available. There comes a time when replacement is better than repairs.

If your system is older than 10 years it’s worth considering replacement. Modern systems are more energy efficient, while you could also upgrade to a heat pump or solar system. Decreased running costs could save you a considerable amount of money each year.

Additionally, a hot water service might be all you need if the system continues to deliver quality hot water. It will ultimately depend on your individual circumstances, so be sure to speak to a licensed plumber about the best option.

This will change depending on what is recommended by the manufacturer, although a 12-month service is often the best. You can keep a close eye on any issues, big or small, and catch anything that might otherwise damage your home.
