Unlike electric storage, gas storage should not be sized from tank litres alone. Gas systems can reheat water quickly while the household is using it, which means recovery rate and first-hour hot water delivery are often just as important as the physical storage capacity.
Gas Storage Hot Water Systems at a Glance
A gas storage hot water system heats water with a gas burner and stores the heated water inside an insulated cylinder ready for use. As hot water is drawn from the tank, the burner can recover additional hot water relatively quickly.
| Feature | Gas Storage | Why It Matters |
|---|---|---|
| Stored Hot Water | Yes | Hot water is already stored and ready for household demand |
| Heating Fuel | Natural gas or LPG on compatible models | The correct model must suit the property's gas type |
| Recovery | Generally strong | The burner can replace hot water while the system is being used |
| Sizing | Storage + recovery | Tank litres alone do not describe total hot water performance |
| Energy Rating | Commonly 4-Star or 5-Star in current ranges | Helps compare gas efficiency between suitable systems |
| Best Suited To | Homes with suitable gas supply wanting stored hot water | Particularly useful for straightforward gas-storage replacements |
Gas Storage Sizing: Tank Capacity vs Recovery Rate
This is one of the biggest differences between gas storage and electric storage hot water. The litre capacity printed on the tank does not tell the full story because a gas burner can replace hot water quickly while the household is using it.
A useful way to compare gas storage systems is by looking at first-hour hot water delivery. This considers both the hot water stored in the cylinder and the amount the burner can recover during the following hour.
| Example System | Storage Capacity | Recovery Rate | First-Hour Delivery |
|---|---|---|---|
| Rheem Stellar 330 | 130L | 200L/hour | Approximately 330L |
| Rheem Stellar 360 | 160L | 200L/hour | Approximately 360L |
| Everhot 5-Star 130L | 130L | Approximately 142L/hour | Approximately 272L |
| Everhot 5-Star 160L | 160L | Approximately 142L/hour | Approximately 302L |
What Size Gas Storage Hot Water System Do I Need?
Household size is only the starting point. When we size gas storage, we also consider bathrooms, simultaneous showers, bath use, peak morning and evening demand, storage capacity and the system's recovery rate.
130L–135L Gas Storage
A common gas-storage size for small to medium households. The actual household capacity depends heavily on the burner's recovery rate, so two tanks with similar storage litres can perform very differently.
160L Gas Storage
Additional storage for larger families or homes with stronger peak demand. High-recovery 160L systems can provide a substantial first hour of usable hot water.
High-Recovery Gas Storage
Premium high-recovery systems are particularly useful where several people use hot water close together or multiple outlets may operate during busy household periods.
Natural Gas vs LPG Gas Storage Hot Water Systems
Gas storage water heaters are manufactured for a specific gas type. Depending on the model, versions may be available for natural gas, propane/LPG or both as separate model variants. The correct version needs to be selected for the property's gas supply.
| Comparison | Natural Gas | LPG / Propane |
|---|---|---|
| Supply | Usually connected to a reticulated natural gas network | Normally supplied from LPG cylinders or another suitable LPG supply |
| System Model | Must be approved for natural gas | Must be approved for LPG / propane |
| Fuel Availability | Dependent on gas network availability | Can suit properties without reticulated natural gas |
| Fuel Cost | Depends on current gas plan and usage | Depends on LPG pricing, cylinder arrangement and usage |
| Replacement | Usually simplest where natural gas already serves the old system | Usually simplest where a compliant LPG setup already exists |
4-Star vs 5-Star Gas Storage Hot Water
Gas energy ratings help compare the efficiency of gas water heaters. Current residential gas storage ranges include both 4-Star and 5-Star options, with premium 5-Star systems generally designed to make better use of the gas consumed.
| Comparison | 4-Star Gas Storage | 5-Star Gas Storage |
|---|---|---|
| Upfront Position | Generally value focused | Generally more premium |
| Gas Efficiency | Good standard gas-storage efficiency | Higher gas energy efficiency |
| Product Examples | Vulcan 4-Star 135L | Rheem Stellar and Everhot 5-Star ranges |
| Best For | Practical replacement and lower upfront spend | Homes prioritising stronger efficiency or premium recovery |
How Much Does a Gas Storage Hot Water System Cost?
Calculated from currently available products in this collection using each product's lowest available advertised starting price. Your final supplied-and-installed price depends on the system, gas type, installation pathway and site requirements.
Gas storage hot water system cost depends on the model, storage capacity, gas energy rating, gas type and installation requirements. A straightforward like-for-like replacement generally costs less than a relocation, fuel conversion or installation requiring substantial gas pipework changes.
JR Gas & Water displays current gas storage systems and installed prices in the product range above so customers can compare actual available options rather than relying on a broad price estimate.
What Can Change the Gas Storage Installation Price?
- Brand and gas storage model.
- Natural gas or LPG configuration.
- 4-Star versus 5-Star system choice.
- Existing gas pipe size and gas supply suitability.
- Like-for-like replacement versus relocation.
- Condition of existing hot and cold water pipework.
- Valves and isolation requirements.
- Drainage and relief valve discharge requirements.
- System base and support requirements.
- Access to the existing hot water system.
- Clearance or installation-location changes.
- Removal and disposal requirements for the old system.
Gas Storage Replacement Cost: What Are You Paying For?
The product price is only the starting point. The final replacement price depends on whether the job is a straightforward like-for-like swap or needs gas pipe changes, valve work, drainage, a new support base, relocation, LPG changes or other site work.
Like-for-Like Replacement
Usually the simplest cost pathway where the existing gas type, pipe capacity, water connections, drainage, position and base remain suitable for the new cylinder.
Higher-Recovery Upgrade
Moving to a higher-output or premium 5-Star system can change appliance cost and may require the available gas supply to be checked for the new burner input.
Natural Gas or LPG
The appliance must match the property's fuel type. LPG-specific equipment, cylinder arrangements, regulators or gas-supply changes can affect the installed scope.
Relocation or Technology Change
Moving the cylinder or converting from another hot water type can add gas, water, drainage, base and compliance work compared with a direct replacement.
Advertised Gas Storage Price vs Supplied-and-Installed Price
The advertised starting price helps compare models, capacities, recovery and efficiency. The installed total also needs to account for the selected installation package and the property's existing services. Use the selector and installation options already on this page for the actual pathway rather than relying on a generic one-price-fits-all estimate.
What Is Usually the Lowest-Cost Gas Storage Replacement?
A correctly sized like-for-like replacement is usually the lowest-complexity option when the existing gas type, pipework, water connections, drainage, location and base remain suitable. The cheapest cylinder is not always the cheapest installed result if it requires additional gas or site work.
Does 4-Star vs 5-Star Change the Price?
Higher-efficiency or high-recovery systems can have a higher purchase price, but the right comparison is the complete installed cost, first-hour delivery, household demand and expected gas use. A lower-cost 4-Star system can be a sensible like-for-like replacement where value is the priority, while premium 5-Star systems may suit households prioritising stronger efficiency or recovery.

View Rinnai hot water systems →Gas Storage Hot Water Installation Brisbane & Gold Coast
JR Gas & Water provides licensed gas storage hot water installation and replacement throughout Brisbane and the Gold Coast. A compliant gas hot water installation involves considerably more than placing a new cylinder where the old one was.
Gas Supply
The existing gas type, supply and pipework need to be suitable for the selected water heater and the other gas appliances connected to the property.
System Location
The position needs to satisfy the requirements of the specific gas water heater, including access, support, clearances and safe installation around the building.
Plumbing & Valves
Hot and cold water pipework, isolation, control valves, relief drainage and pressure requirements all form part of the installation.
Gasfitting & Commissioning
Gas connections and required gasfitting work must be completed by a suitably licensed gasfitter, with the system tested and commissioned before use.
Replacing an Existing Gas Storage Hot Water System
Gas storage is often one of the most straightforward replacement options when a property already has a suitable gas storage installation. Existing water, gas and drainage services may already be positioned around a storage water heater, reducing the amount of change required compared with converting to a completely different technology.
Before Replacing Gas Storage, We Consider:
- Whether the old cylinder has failed or the fault is repairable.
- The household's current hot water demand.
- The first-hour delivery of the existing system.
- Whether the home needs stronger or lower recovery than before.
- Natural gas or LPG compatibility.
- The existing gas pipework and supply.
- Whether the existing system position remains suitable.
- Whether storage gas is still the best technology for the property.
Gas Storage vs Instant Gas Hot Water
Both technologies use gas, but they deliver hot water very differently. Gas storage heats and stores a reserve of hot water in a cylinder. Instant or continuous-flow gas heats water as it passes through the unit when a tap is opened.
| Comparison | Gas Storage | Instant / Continuous Flow Gas |
|---|---|---|
| Hot Water | Stored in a tank | Heated on demand |
| Physical Size | Requires storage-cylinder space | Compact wall-mounted unit |
| Peak Demand | Uses stored volume plus burner recovery | Performance is governed by flow rate and available gas supply |
| Running Behaviour | Maintains stored hot water | Burner operates when hot water flows |
| Replacement Appeal | Very strong where gas storage already exists | Strong where the property suits continuous flow |
| Best For | Homes wanting familiar stored hot water and strong recovery | Homes wanting compact on-demand hot water without a tank |
Gas Storage vs Electric Hot Water
Both systems store hot water in a tank, but the way they reheat that water is very different. Gas storage uses a gas burner, while standard electric storage uses an electric resistance element.
| Comparison | Gas Storage | Electric Storage |
|---|---|---|
| Heating Fuel | Natural gas or LPG | Electricity |
| Recovery | Can be very fast on high-recovery models | Dependent on element power and heating arrangement |
| Gas Supply Required | Yes | No |
| Off-Peak Electricity | Not applicable | Can be useful on suitable installations |
| Best Replacement | Often strongest where suitable gas storage already exists | Often strongest where electric storage already exists |
If the property is considering moving away from gas altogether, the conversion cost and future fuel strategy should be considered rather than comparing the purchase price of the tanks alone.
Gas Storage vs Heat Pump Hot Water
Gas storage and heat pumps represent two very different hot water strategies. Gas storage uses a gas burner and provides strong recovery, while a heat pump uses electricity to transfer heat from the surrounding air into stored water.
| Comparison | Gas Storage | Heat Pump |
|---|---|---|
| Energy Source | Natural gas or LPG | Electricity + heat from ambient air |
| Recovery | Strong on high-recovery models | Varies considerably by heat-pump model |
| Operating Noise | Burner operation | Fan and compressor operation |
| Gas Connection | Required | Not required |
| Solar PV Integration | Not directly | Can be scheduled around household solar generation |
| Best For | Homes already set up for gas wanting strong storage recovery | Homes prioritising reduced water-heating energy consumption |

What We Have Learned Installing Gas Storage Hot Water Systems
Gas storage is a relatively simple category until systems are compared purely by tank size. In practice, recovery, first-hour delivery and the existing gas installation have a major effect on how well a replacement performs.
Tank Litres Do Not Tell the Whole Story
A 130L high-recovery gas system can provide significantly more usable hot water through a busy hour than the storage figure alone suggests.
Size for the Busiest Hour
Morning showers and evening family use often matter more than total daily water consumption when selecting gas storage.
Check the Gas Supply Before Upgrading
Choosing a higher-output gas appliance does not automatically mean the existing gas installation is suitable for it.
Natural Gas and LPG Are Not the Same Model
Always confirm the exact gas type and product variant rather than assuming the same water heater can simply be connected to either fuel.
Continuous Flow Is Not Automatically Better
High-recovery gas storage remains an excellent option for busy households and can be the simplest replacement for an existing storage installation.
Replacement Is the Time to Reassess Gas
If the property is already considering electrification or has strong rooftop solar, a failed gas system is a sensible time to compare electric or heat-pump alternatives before automatically staying on gas.
Gas Storage Hot Water System FAQs
How does a gas storage hot water system work?
A gas storage system heats water with a gas burner and stores the heated water inside an insulated tank. When hot water is used, cold water enters the cylinder and the burner reheats the replacement water. This recovery allows a gas storage system to deliver more usable hot water than the tank capacity alone may suggest.
How much does a gas storage hot water system cost installed?
Installed cost depends on the brand, model, gas type and work required at the property. A straightforward like-for-like replacement generally costs less than relocation or work requiring substantial changes to gas pipework, drainage or the installation area. JR's current installed prices are shown in the product range above.
What is the current gas storage hot water price range?
Current available systems in this collection have advertised starting prices from to . Your exact supplied-and-installed price depends on the system, gas type and site requirements shown through the live installation options above.
Why can the installed price be higher than the advertised gas storage price?
Gas pipe changes, valves, drainage, support base work, relocation, LPG requirements, access and other site work can change the final total. A from price is the starting point for the relevant product or installation pathway.
Can I compare gas storage prices without requesting a quote?
Yes. JR publishes gas storage products and installation options online so you can compare brands, capacities, recovery and starting prices before booking. A written or onsite quote remains available where the job falls outside the standard online pathways.
What size gas storage hot water system do I need?
Gas storage should be sized using both storage capacity and recovery rate. Household size, bathrooms, simultaneous use and peak demand also matter. A high-recovery 130L system may suit a household that would require a much larger tank with a slower-heating technology.
What does first-hour delivery mean for gas hot water?
First-hour delivery combines the hot water initially stored in the tank with the additional hot water the burner can recover during approximately the first hour of use. It is a useful way to compare gas storage systems because it reflects both tank capacity and recovery performance.
Why is the Rheem Stellar 330 only a 130L tank?
The "330" refers to approximately 330 litres of first-hour hot water delivery rather than physical tank capacity. The Stellar 330 stores approximately 130L and can recover around 200L per hour under the specified test conditions, giving approximately 330L of first-hour capacity.
What is the difference between Rheem Stellar 330 and 360?
The Stellar 330 stores approximately 130L while the Stellar 360 stores approximately 160L. Both have high recovery, with the larger 360 providing additional stored capacity and approximately 360L of first-hour hot water delivery.
Can gas storage hot water run on LPG?
Some gas storage systems are available in LPG or propane-specific variants, while others are natural-gas only. The correct model must be chosen for the property's gas type. Do not assume every natural gas storage water heater is also suitable for LPG.
Is 5-Star gas storage better than 4-Star?
A higher gas energy rating indicates better gas efficiency under the applicable rating method, but star rating is not the only consideration. Recovery, tank capacity, gas type, household demand, warranty and installed cost should also be compared.
Is gas storage better than instant gas hot water?
Neither is automatically better. Gas storage provides a stored reserve combined with burner recovery, while continuous-flow gas heats water as it is used and avoids a storage tank. The best option depends on household demand, gas supply, available space and the existing installation.
Should I replace gas storage with a heat pump?
It is worth comparing if the goal is to move away from gas or reduce water-heating energy consumption. Staying with gas storage can provide the simplest replacement where the existing gas installation remains suitable, while a heat pump can be attractive for homes prioritising electrification and lower energy use.
Can a gas storage hot water system be repaired?
Some gas storage faults can be repaired depending on the component, system age and availability of parts. A leaking or structurally failed storage cylinder will generally require replacement rather than repair.
Do I need a licensed gasfitter to install gas hot water?
Yes. Gasfitting work must be completed by an appropriately licensed gasfitter. Gas storage installation also involves plumbing, drainage, testing and commissioning requirements that need to be completed correctly.
Do you install gas storage hot water in Brisbane and the Gold Coast?
Yes. JR Gas & Water supplies and installs gas storage hot water systems throughout Greater Brisbane, the Gold Coast, Logan, Ipswich, Redlands, Moreton Bay and surrounding South East Queensland service areas.
