Gas Storage Hot Water Systems – Perth Resource Guide 2025

Gas storage systems are one of the most common hot water setups in Perth homes. They’re familiar, affordable, and often the simplest choice for homeowners looking to replace an older system.

At Banrock Plumbing, we regularly supply and install gas storage units for households across Perth — especially in properties already connected to mains gas. If you’re replacing an existing gas storage system, a like-for-like swap is usually cost-effective, quick to install, and gets your hot water running again quickly.

Why Choose a Gas Storage Hot Water System?

Gas storage systems heat water using a burner underneath a tank. Hot water is kept in reserve and replenished as it’s used, so there’s always some ready to go.

Some key benefits include:

Works during blackouts — no electricity required, so your hot water won’t cut out if the power does
Faster recovery times than electric systems
Affordable upfront cost, especially for replacements
Simple, reliable technology that’s easy to maintain
Built-in storage means you still have hot water during peak use or brief outages

Standard sizes are 135L or 170L, which suits most small to medium households.

Recommended Brands for Gas Storage Hot Water Systems in Perth

At Banrock Plumbing, we stick to reliable, proven brands that perform well in Perth conditions. For gas storage systems, we typically recommend:

Rheem – a long-standing Australian favourite known for durability and easy servicing
Dux – efficient and affordable, with strong local support
Vulcan – a budget-friendly option backed by Rheem’s service network

We supply models that balance performance, longevity, and value — and we’re happy to advise on the best fit for your home.

Maintenance and Lifespan of Gas Storage Hot Water Systems

Gas storage systems are relatively low maintenance. Homeowners are encouraged to:

Do a quick visual check every few months, and activate the pressure relief valves briefly to ensure they’re functioning and to help prevent buildup
Book a major service every 5 years to keep things running smoothly

With proper care, these systems typically last 10 to 15 years. They’ll often still function beyond that, but timely servicing extends their lifespan and helps maintain efficiency.

Is It Time to Upgrade Your Hot Water?

If your current gas storage unit is getting old or no longer meeting your needs, it might be the perfect time to explore more energy-efficient options — especially heat pump hot water systems.

Heat pumps are:

Cheaper to run long-term
All-electric, helping you move away from gas
Quiet and space-efficient

We often recommend them when a gas storage system is due for replacement, with comparable installation costs and real potential for long-term savings.

That said, if a straightforward replacement is all you need, Banrock Plumbing can supply and install a new gas storage unit quickly and professionally.
