What Is a Gas Storage Hot Water System? (And Why Perth Homes Still Use Them)

A gas storage system is different from instantaneous hot water or from something running on electricity and heat pumps. A gas water heater stores and heats a full tank of hot water, keeping it ready for use whenever you need it during the day. Instead of turning on only when the tap runs (like instantaneous units), the storage model maintains a ready supply always preheated.
Busier households with frequent hot water use find greater reliability with these units because the gas hot water system offers stronger recovery and steadier performance. The primary reasons to select gas storage hot water systems in Perth include:

Fast and consistent heating all day long

Easy to integrate with Natural Gas and LPG

Can handle high-demand households

Can be more cost-effective

Easy to maintain and repair

Hot water systems Perth homeowners use gas-powered units for both warmer summers and cool winter nights, making them practical in the city or more rural areas.

How to Choose the Right Gas Storage Hot Water System in Perth

Our team at Sarros Hot Water offers a large variety of gas storage hot water systems for Perth residents. 
You can find everything from the Rinnai 170L Gas Storage Water Heater to the more traditional Rheem Stellar 330 Gas Hot Water System. The trick is finding what works best for your unique needs.
Choose your tank based on:

How many people will be using hot water in the home

Morning and evening shower schedules

Use of common appliances like dishwashers and washing machines

Whether or not you host a lot of guests or extended family

Easy to maintain and repair

A good rule of thumb to help you get started is to shoot for 135L for 2-3 people, 170L to 200L for 3-5 people, and over 360L for five or more people. 
The goal is to have your new hot water system perform without strain, reducing re-heating cycles. That will lower your overall energy costs.

The next thing to consider is what type of fuel you’ll use. Your location affects hot water installation, so always check if your neighbourhood has access to natural gas or LPG. Natural gas tends to be slightly less expensive, but LPG is preferred by those off-grid enthusiasts who want more reliability.

Recovery rate and efficiency are other considerations. Higher recovery rates mean less downtime in hot water availability between showers and better performance, so you get fewer cold-water surprises. Many of our clients look at recovery rates first when considering the best hot water system.

Finally, consider the brand. In Perth, access to parts and service matters. Brands like Rinnai gas storage hot water systems, Vulcan, and Rheem tend to be easier to find parts for, reducing the time of a service appointment or the cost of repairs.

Tips to Extend the Lifespan of Your Gas Storage System

Repairing or replacing your gas storage hot water system Perth can be expensive. You want to look for early signs to plan a hot water replacement before the tanks give out. That might include: 

  • Water takes way too long to heat
  • Rusty coloured water in the tap
  • Dealing with pilot light issues
  • A metallic taste or odour to the water
  • The tank is leaking or sweating
  • Reduced water pressure

If your system is 8 to 12 years old, you need to consider gas hot water repairs or installing a new, more efficient system. However, you can extend the usable lifespan of your device.
Start by scheduling annual service and be sure to flush the tank at least once per year. You should check the anode rod every 3 to 5 years to prevent corrosion and ensure the area around your system is clear for proper ventilation. Try to fix any issues as early as possible by having a hot water repair person ready to call.
