130L & 135L Gas Hot Water Systems for Brisbane, Gold Coast & Major Australian Metros
130L and 135L gas hot water systems provide compact residential gas storage for small-to-medium households wanting a ready supply of stored hot water with fast gas recovery.
This size class is commonly considered for townhouses, rentals, smaller family homes, one-to-two bathroom properties and like-for-like replacement of existing outdoor gas storage systems.
Installed Today supplies 130L and 135L gas-storage systems across supported mainland Australian markets, with supplied and installed options available on selected systems in eligible Brisbane and Gold Coast service areas.
What Is a 130L or 135L Gas Hot Water System?
Who Should Consider 130L or 135L Gas Storage?
Small Families
135L gas storage can suit smaller family households where strong gas recovery supplements the stored-water volume.
Townhouses
Compact outdoor gas storage can be a practical fit where a larger 160L or 170L tank is unnecessary.
Rental Properties
This size class is commonly used where an existing external gas storage system needs a straightforward same-technology replacement.
One to Two Bathrooms
Moderate bathroom demand can fit this storage class where several high-volume outlets are not regularly used together.
Existing 135L Replacement
If the old 135L system has historically provided enough hot water, the same capacity class is the logical replacement starting point.
Customers Staying with Gas
Gas storage can avoid changing technology where the property's current outdoor gas arrangement already works well.
Is There Much Difference Between 130L and 135L?
With conventional storage alone, five litres is a very small difference.
The important distinction in this category is that the main 130L option, Rheem Stellar 330, is a high-recovery premium storage system rather than simply a slightly smaller conventional tank.
That means recovery and first-hour capacity can matter considerably more than the nominal difference between 130L and 135L.
Gas Storage Performance Is Not Just the Tank Size
A gas-storage system continues reheating incoming water as hot water is drawn from the cylinder.
This makes recovery rate an important part of household performance.
A strong-recovery system can provide substantially more usable hot water during a busy period than its physical storage volume alone suggests.
Why First-Hour Capacity Matters
First-hour capacity combines the hot water already stored in the tank with the water the burner can reheat while the household continues using hot water.
This is useful when comparing conventional 135L systems with a high-recovery system such as Rheem Stellar.
For example, the current Rheem 4-Star 135L lists 248L first-hour capacity, even though the physical tank stores 135L.
Rheem, Vulcan & Rinnai 135L Gas Storage
Installed Today's core 135L gas-storage range includes Rheem, Vulcan and Rinnai.
Natural Gas and LPG variants are represented across these brands, providing options for properties connected to mains gas and properties using LPG.
Current 135L systems are predominantly conventional 4-Star gas-storage water heaters.
Rheem 4-Star 135L Gas Storage
Rheem's current 135L gas-storage system provides 135L storage and approximately 248L first-hour capacity.
It is available in both Natural Gas and LPG versions and is made in Australia.
It is a strong like-for-like replacement option for homes already using outdoor Rheem or similar 135L gas storage.
Vulcan 4-Star 135L Gas Storage
Vulcan provides a conventional 135L gas-storage option in both Natural Gas and LPG configurations.
The current Natural Gas model uses a 135L vitreous-enamel-lined cylinder and is listed for approximately 4–5 occupants as a general sizing starting point.
It is made in Australia and designed for outdoor gas-storage installation.
Rinnai Hotflo 135L Gas Storage
Rinnai Hotflo provides another 135L 4-Star gas-storage choice within the current Installed Today range.
Natural Gas and LPG models are represented, with the current Rinnai sizing data positioning the 135L class around 4–5 occupants.
As with any replacement, check exact dimensions, gas type, warranty and connection positions rather than assuming every 135L cylinder is physically identical.
Rheem Stellar 330 as the Premium 130L Option
Rheem Stellar 330 sits differently from conventional 135L systems.
Its physical tank stores approximately 130L, while the model name reflects approximately 330L first-hour hot-water capacity.
This makes it relevant to households wanting compact gas storage with stronger recovery and premium 5-Star efficiency.
135L Natural Gas vs LPG Hot Water Systems
Natural Gas
Designed for homes connected to an appropriate mains Natural Gas supply.
LPG
Designed for properties supplied by LPG and can suit locations without mains Natural Gas.
Confirm the Fuel
Natural Gas and LPG versions are different appliances and should not be treated as interchangeable.
135L vs 160L / 170L Gas Hot Water
| Storage Class | Typical Starting Point | Main Advantage | Main Question |
|---|---|---|---|
| 130L / 135L | Small-to-medium household demand | More compact storage and replacement footprint | Is recovery enough for peak household use? |
| 160L / 170L | Family and stronger stored demand | Greater stored-water reserve | Does the household genuinely need the larger tank? |
When Is 135L Too Small?
A larger 160L or 170L system is worth comparing when the existing 135L tank regularly struggles despite operating correctly.
Common reasons include increased household occupancy, more bathrooms, longer showers, regular baths or several hot-water uses occurring close together.
Strong recovery can reduce the need for additional storage, so compare the full performance of the candidate systems rather than tank litres alone.
135L Gas Storage vs Instant Gas Hot Water
135L Gas Storage
Stores hot water ready for use and reheats the tank as the stored supply is consumed.
Instant Gas
Heats water as it flows through the appliance rather than storing a full tank of hot water.
Replacement Path
Staying with storage can be simpler where a compliant outdoor gas tank is already installed and performs well.
Conventional 4-Star 135L vs Rheem Stellar 5-Star
Most conventional systems in this size class carry a 4-Star gas-energy rating.
Rheem Stellar 330 provides the premium alternative with a 5-Star efficiency rating and significantly higher first-hour performance.
Compare upfront cost, recovery, household demand and expected gas use rather than selecting from the star rating alone.
Check Gas Pipe and Supply Capacity
A replacement gas-storage system needs an adequately sized gas supply.
Existing pipework should not automatically be assumed suitable simply because another gas-storage unit is already installed.
Gas type, burner input, pipe length, other gas appliances and regulator capacity can all affect suitability.
130L and 135L Gas Storage Is Designed Around Outdoor Installation
Current systems in this class are designed for external gas-storage applications.
The location needs suitable outdoor clearances, access, drainage, a stable base and compliant gas and water connections.
Do not assume an outdoor gas-storage unit can be installed internally or inside an enclosed cupboard.
135L Gas Storage Is Narrower Than Many Large Storage Tanks
The current Vulcan 135L is approximately 422mm wide × 1558mm high, while the current Rinnai 135L is approximately 450mm wide × 1579mm high.
This relatively narrow external format can make 135L storage practical where side access or available footprint is limited.
Exact dimensions still vary between brands, so always measure the installation location before ordering.
Replacing an Existing 130L or 135L Gas Hot Water System
A same-size gas-storage replacement is usually the logical starting point where the old system supplied enough hot water and the household has not materially changed.
- Existing brand and model
- Natural Gas or LPG
- Existing storage capacity
- Current household demand
- Gas pipe sizing
- Regulator capacity
- Water pressure
- Valve condition
- Tank dimensions
- Connection positions
- Base condition
- Drainage and access
135L Gas Hot Water for Families and Rental Properties
Conventional 135L gas storage can provide a practical middle ground for small-to-medium family demand.
Current Vulcan and Rinnai sizing information places this capacity around 4–5 occupants as a broad starting point.
Actual suitability depends on showers, climate, bathroom use, outlet flow rates and recovery, so occupant count should not be treated as an absolute limit.

130L / 135L Gas Hot Water System FAQs
Common questions about choosing, ordering and installing 130L and 135L gas storage hot water systems for homes using natural gas or LPG.
What is a 130L or 135L gas hot water system best suited for?
A 130L or 135L gas storage hot water system is best suited to homes wanting reliable stored hot water with gas heating. These systems are commonly used for household replacements where the existing property has natural gas or LPG available and a similar-sized outdoor gas storage unit already installed.
How many people does a 130L or 135L gas storage system suit?
A 130L or 135L gas storage hot water system commonly suits smaller to medium households, depending on shower length, daily hot water use, recovery rate, bathroom count and household habits. Heavy hot water users or larger families may need to compare larger gas storage or continuous flow options.
What is the difference between LPG and natural gas models?
LPG and natural gas models are made for different gas supplies. A natural gas unit is for homes connected to mains gas, while an LPG unit is for homes using bottled gas. The correct gas type must be selected before ordering because LPG and natural gas units are not interchangeable without the correct manufacturer-approved setup.
Can I buy a 130L or 135L gas hot water system supply only?
Yes. Choose supply only if you already have a licensed plumber or gas fitter arranged. Supply-only pricing is for the hot water system only and does not include installation, valves, old unit removal, disposal, gas work, pipework changes, flue work or compliance upgrades unless selected separately.
Can I order a 130L or 135L gas hot water system supplied and installed?
Yes. Supplied and installed options are available for selected 130L and 135L gas storage hot water systems in eligible Brisbane and Gold Coast service areas. Availability depends on your location, access, gas type, existing setup, gas compliance requirements and site conditions.
Can I replace my old 135L gas hot water system with another 135L unit?
In many cases, a like-for-like 135L gas storage replacement can be a practical option, but the new system still needs to suit the existing location, gas supply, plumbing connections, clearances, ventilation, drainage and current compliance requirements.
Are gas storage hot water systems installed indoors?
Standard external gas storage hot water systems are designed for outdoor installation. Do not assume a gas unit can be installed internally unless it is a manufacturer-approved internal or flued model and the installation meets all required ventilation, flueing and compliance requirements.
Where can a 130L or 135L gas hot water system be installed?
A 130L or 135L gas storage system needs a suitable outdoor location with safe access, compliant plumbing, drainage, gas connection, clearances and ventilation. The exact location depends on the model, property setup, gas type and manufacturer installation requirements.
Does installation include gas work?
Gas work is not automatically included unless shown in the selected installation option or chosen as an add-on. Some replacements may require gas compliance checks, regulator work, pipework changes, isolation valves or other work by a licensed gas fitter.
Does installation include old system removal and disposal?
Old system removal and disposal are not automatically included unless shown in the selected installation option or chosen as an add-on. Access, location, tank size, stairs, mounting and site conditions can affect what is required.
Is a 130L or 135L gas storage system instant?
No. A 130L or 135L gas storage hot water system heats and stores hot water inside a tank. It is different from an instant gas continuous flow system, which heats water as it passes through the unit. Gas storage systems can still recover quickly, but they are not instant systems.
Do you install 130L and 135L gas hot water systems in Brisbane and the Gold Coast?
Supplied and installed options are available in eligible Brisbane and Gold Coast service areas. Availability depends on the selected product, your address, gas type, access, existing system and installation requirements.
