160L & 170L Gas Hot Water Systems for Brisbane, Gold Coast & Major Australian Metros
160L and 170L gas hot water systems are larger gas-storage water heaters designed for family homes, rental properties and households wanting more stored hot water than smaller 130L or 135L gas systems.
The current Installed Today range includes Natural Gas and LPG storage options from Rheem, Vulcan and Rinnai, with 170L systems forming the core of the collection.
Installed Today supplies 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.
Current 160L & 170L Gas Storage Range
What Is a 160L or 170L Gas Hot Water System?
A gas-storage hot-water system heats water using gas and keeps that heated water inside a storage cylinder ready for use.
When hot water leaves the tank, incoming cold water replaces it and the gas burner reheats the stored supply.
This is different from continuous-flow gas systems, which heat water as it passes through the appliance and do not maintain a full storage tank.
Who Should Consider 160L or 170L Gas Storage?
Family Homes
Larger storage and gas recovery can suit families with regular morning and evening hot-water demand.
Rental Properties
160L and 170L systems can provide a practical replacement for family-sized rental properties already using outdoor gas storage.
One to Two Bathrooms
These systems can suit homes with regular bathroom demand where a smaller 130L/135L tank may provide less stored-water buffer.
Existing Gas Storage
They are particularly relevant when replacing an existing 160L, 170L or similar gas-storage system.
Higher Daily Demand
More stored capacity can help households with concentrated periods of showers, kitchen use and other hot-water demand.
Customers Staying with Gas
A storage replacement can avoid changing hot-water technology when the existing gas arrangement already suits the property.
Is There Much Difference Between 160L and 170L Gas Storage?
The nominal storage difference between 160L and 170L is relatively small.
In practice, burner input, recovery rate, first-hour capacity, efficiency rating and existing installation compatibility can matter more than the extra 10 litres of stored water.
That means a well-matched 160L system with strong recovery can compete effectively with a conventional 170L storage system during peak household demand.
Gas Storage Is About More Than Tank Capacity
A gas-storage system can continue heating water while the household is using it.
This makes recovery rate particularly important when comparing gas storage.
Two systems with similar physical storage capacity can provide different real-world performance if one replenishes the hot-water supply faster.
Why First-Hour Capacity Matters
First-hour capacity combines the hot water initially stored in the tank with the additional hot water produced as the gas burner recovers the cylinder.
This can provide a more useful comparison of high-demand performance than tank volume alone.
Premium gas-storage systems such as Rheem Stellar are especially relevant here because their model names reflect first-hour delivery rather than physical tank capacity.
Rheem, Vulcan & Rinnai Gas Storage Systems
The live collection currently includes 7 gas-storage products across Rheem, Vulcan and Rinnai.
Current options include Rheem Stellar 330, Rheem Stellar 360, Rheem 4-Star 170L, Vulcan 4-Star 170L and Rinnai 4-Star 170L variants, with both Natural Gas and LPG represented across the collection.
Availability can vary by exact fuel type and model, so confirm the live product status before ordering.
Rheem Stellar 360 as the Premium 160L Option
Rheem Stellar 360 provides approximately 160L of physical storage with substantially higher first-hour delivery because of its strong gas recovery.
It is therefore a premium alternative to conventional 170L gas-storage systems rather than simply being judged by its slightly smaller tank.
It can suit larger households wanting high gas-storage performance without changing to continuous flow.
Why Is Rheem Stellar 330 in This Collection?
Rheem Stellar 330 is included as a premium gas-storage comparison even though its physical cylinder stores approximately 130L.
Its model number refers to its first-hour hot-water delivery rather than tank volume.
Its strong recovery allows it to compete with physically larger conventional storage systems for family hot-water demand.
Rheem 4-Star 170L Gas Storage
Rheem's conventional 170L gas-storage range provides a direct family-sized alternative for customers wanting a traditional outdoor storage replacement.
The current Rheem 170L Natural Gas model has 170L physical storage and approximately 283L first-hour capacity.
Natural Gas and LPG variants are represented in the current collection, subject to live availability.
Vulcan 4-Star 170L Gas Storage
Vulcan 170L provides another conventional 4-Star gas-storage choice for medium-to-large households.
The live Natural Gas model uses a 170L vitreous-enamel-lined storage cylinder and is designed for outdoor installation.
It is particularly relevant as a straightforward replacement where the property already has a similar external gas-storage system.
Natural Gas and LPG 160L / 170L Systems
Natural Gas
Designed for properties connected to an appropriate mains Natural Gas supply.
LPG
Designed for properties using LPG and can suit homes without a mains Natural Gas connection.
Confirm Before Ordering
Natural Gas and LPG models are different fuel configurations and should not be treated as interchangeable products.
130L / 135L vs 160L / 170L Gas Storage
| Storage Class | Typical Starting Point | Why Choose It | Main Question |
|---|---|---|---|
| 130L / 135L | Lower-to-moderate family demand | Smaller physical storage and footprint | Will recovery comfortably cover peak use? |
| 160L / 170L | Family and higher-demand homes | Greater stored-water buffer | Does the household need the additional capacity? |
160L / 170L Gas Storage vs Instant Gas Hot Water
Gas Storage
Keeps a tank of hot water ready and uses gas recovery to replace the heated water as it is consumed.
Instant Gas
Heats water as it flows through the appliance and does not maintain a full storage cylinder.
Replacement Decision
Staying with gas storage can be the simpler pathway where the existing outdoor tank arrangement already works well.
Check the Existing Gas Supply Before Replacement
The existing gas supply needs to provide adequate capacity for the new hot-water system and any other gas appliances that may operate at the same time.
Gas pipe sizing should not be assumed correct simply because another gas hot-water system is already installed.
Changing brands, burner capacity or system type can alter the gas requirements.
160L and 170L Gas Storage Is Typically an Outdoor Installation
Current conventional systems in this category are designed around external gas-storage installation.
The replacement location needs suitable access, clearances, stable support, drainage and compliant gas and water connections.
Do not assume an outdoor gas-storage appliance can simply be installed within an enclosed internal area.
Measure the Existing Gas Storage System Before Ordering
The current collection is concentrated around relatively narrow external cylinders, but heights differ between systems.
The live collection spans approximately 1600mm through 2000mm height classes while all seven current products sit within the site's 400–500mm width category.
Check height, width, connection positions and service access rather than assuming every 170L model is physically interchangeable.
Replacing an Existing 160L or 170L Gas Hot Water System
If the existing system has reliably supplied enough hot water, another correctly selected 160L or 170L gas-storage system is the most logical replacement starting point.
- Existing brand and model
- Natural Gas or LPG
- Existing tank capacity
- Current household demand
- Gas pipe sizing
- Regulator or supply suitability
- Water pressure
- Existing valves
- Tank dimensions
- Connection positions
- Base condition
- Drainage and access
Moving from 135L to 170L Gas Storage
Increasing from a conventional 130L or 135L gas tank to 160L or 170L can provide a larger stored-water buffer where household demand has increased.
This can be useful after occupancy increases, more bathrooms are used or back-to-back showers become more common.
Before upsizing, confirm the installation position, gas supply, connections and household need rather than choosing the larger system automatically.
160L and 170L Gas Storage for Families and Rentals
This size class is well suited to family homes and larger rental properties because it combines a substantial stored-water reserve with gas recovery.
Rental owners should size around realistic tenant occupancy rather than simply choosing the lowest-cost replacement.
Homes with much heavier multi-bathroom demand should also compare premium high-recovery storage or appropriately sized continuous-flow gas options.

160L / 170L Gas Hot Water System FAQs
Common questions about choosing, ordering and installing 160L and 170L gas storage hot water systems for homes using natural gas or LPG.
What is a 160L or 170L gas hot water system best suited for?
A 160L or 170L gas storage hot water system is best suited to homes wanting larger stored hot water capacity with gas heating. These systems are commonly used for family households, higher-demand replacements and properties where natural gas or LPG is already available.
How many people does a 160L or 170L gas storage system suit?
A 160L or 170L gas storage hot water system commonly suits medium to larger households, depending on shower length, daily hot water use, recovery rate, bathroom count and household habits. Heavy hot water users may still 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 160L or 170L 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 160L or 170L gas hot water system supplied and installed?
Yes. Supplied and installed options are available for selected 160L and 170L 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 170L gas hot water system with another 170L unit?
In many cases, a like-for-like 170L 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 160L or 170L gas hot water system be installed?
A 160L or 170L 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 160L or 170L gas storage system instant?
No. A 160L or 170L 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 160L and 170L 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.
