Storage Hot Water Systems

Storage hot water systems supply heated water to Australian homes through an insulated tank that holds water at temperature and ready on demand. The range covers gas storage and electric storage options across a variety of tank capacities, suited to households with consistent daily usage across multiple taps and bathrooms.

How to choose

Gas and Electric Storage Hot Water Systems

Both types store water at mains pressure, so flow stays consistent at the tap even when multiple outlets are in use at once. Gas systems generally recover faster after peak demand, while electric models suit properties without natural gas or those on off-peak electricity tariffs.

Gas storage hot water systems

Heat water using a burner at the base of the tank. Hot exhaust gases travel up the sides of the tank, bringing the water to the set temperature. A thermostat monitors water temperature and turns the burner on or off as needed to keep it consistent.

Electric storage systems

Use a heating element inside the tank, similar in principle to a kettle. Cold water enters at the bottom, heats progressively, and the hottest water exits from the top when a tap is turned on. A thermostat keeps the water at the right temperature by adjusting the power to the element.

Why a Storage Hot Water System is a Right Choice

Storage hot water is a practical choice for households with predictable daily usage patterns and a need for dependable supply during busy periods. A storage hot water system keeps a ready supply of heated water available whenever you need it. Key advantages of storage hot water over other system types:

  • Reliable supply during peak demand: the tank holds enough heated water for back-to-back showers, dishwashers, and laundry running simultaneously
  • Consistent mains pressure: hot water is delivered at full pressure to every tap, regardless of how many are open
  • Simple, proven technology: fewer components than continuous flow or heat pump systems, which keeps servicing straightforward
  • Fuel flexibility: available in gas and electric configurations to suit your property's existing connections
  • Built for Australian conditions: tanks and components are designed to handle local water quality and climate demands

Frequently Asked Questions

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

Gas systems heat water using a burner under the tank and recover faster after peak demand. Electric systems use a heating element inside the tank and suit homes without a gas connection or those on off-peak electricity tariffs.

What size hot water storage tank do I need?

Tank size depends on the number of people in your home and how many bathrooms are in regular use. A household of four typically needs a 160 to 250 litre unit. We'll confirm correct sizing before recommending a system.

Can I replace my old gas hot water system with an electric storage unit?

Yes, though it requires running a suitable electrical circuit to the unit's location. It's worth getting a proper assessment first to compare running costs and confirm the installation requirements for your property.

How long do storage hot water systems typically last?

Most quality storage hot water tanks last between 8 and 12 years with regular maintenance. Flushing sediment from the tank annually and checking the anode rod every few years helps extend service life.

Do storage hot water systems work during a power or gas outage?

Electric systems won't heat water during a power outage, though insulated tanks hold temperature for several hours. Gas storage systems with a pilot light can continue operating during power outages since they don't rely on electricity to run the burner.
