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
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
- Everhot – similarly priced to Vulcan and also backed by strong service support, ideal for straightforward replacements
- Thermann – growing in popularity for its solid performance and value
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
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?
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.
