Gas Storage Hot Water Systems – Mandurah to Rockingham

Storage systems have long been the most popular type of hot water systems installed in Australian homes. Because storage technology has been around for a long time, it offers proven reliability. Plus, there are many capacity options available to suit different usage needs.

Both electric and gas storage systems have similar advantages and disadvantages. Storage systems have the lowest upfront cost of all hot water system types. Doing a ‘like for like’ replacement of an existing storage unit will generally keep the installation cost low. Hiring a skilled hot water system installer ensures the best performance and longevity of your system.

Frequently Asked Questions

What is a storage hot water system?

A storage hot water system heats and holds a volume of water in an insulated tank, keeping it ready for use at any time. The tank is refilled with cold water as hot water is drawn off, and the heating element (electric) or burner (gas) maintains the stored water at a set temperature. Storage systems are the most common type of hot water system installed in Australian homes and are available in a range of capacities from around 80 litres for a single person up to 400 litres or more for large households.

What size storage hot water system do I need for my home?

As a general guide, allow approximately 50 litres of tank capacity per person for electric systems, or 30–35 litres per person for gas systems (which heat water more quickly). A family of four would typically suit a 160–200 litre electric system or a 130–160 litre gas system. Off-peak electric systems may require a larger tank — typically 250–315 litres — as they heat water only during designated overnight periods. AJW Plumbing Gas & Air can confirm the right size for your household during a consultation.

How long does a storage hot water system last?

Most storage hot water systems have a service life of eight to twelve years for electric units and ten to fifteen years for quality gas units, provided they receive regular maintenance — particularly annual anode rod inspection and replacement when needed. The anode rod is a sacrificial metal rod inside the tank that prevents internal corrosion; replacing it every three to five years can significantly extend tank life. AJW Plumbing Gas & Air offers hot water maintenance services across Mandurah and Rockingham.

What is the difference between gas and electric storage hot water systems?

Gas storage systems heat water faster and typically have lower running costs than electric storage units, particularly if natural gas is available at your property. Electric storage systems have a lower upfront purchase cost and are simpler to install where no gas connection exists. Electric systems can also be set to heat on off-peak tariffs overnight, which reduces running costs. Gas systems require a gas connection and appropriate flue or ventilation, which may add to installation complexity in some homes.

How do I maintain my storage hot water system to extend its life?

The most important maintenance task is annual inspection and periodic replacement of the sacrificial anode rod — typically every three to five years depending on your water quality. You should also check the pressure relief valve annually to ensure it operates correctly, and flush the tank periodically to remove sediment build-up, which can reduce efficiency and cause the rumbling or popping noises common in older systems. AJW Plumbing Gas & Air provides hot water system maintenance across the Rockingham to Mandurah corridor.

 Trustindex verifies that the original source of the review is Google. I highly recommend Adam. He was able to come out on the same day I contacted him to diagnose an issue with our hot water system. He explained the problem clearly and provided me with different options and information regarding replacement.

Once I decided on the replacement, he had the new system installed within just three days of my initial request. The whole process was quick, professional and straightforward. Very happy with the service!
