Rheem Stellar 330 Natural Gas Hot Water System
The Rheem Stellar 330 Natural Gas Hot Water System is a premium Australian-made gas storage water heater designed for family homes wanting strong recovery, mains-pressure hot water and high-efficiency natural gas storage performance.
Installed Today offers the Rheem Stellar 330 as a supply-only natural gas storage hot water system, with supply and installation options available across eligible Brisbane and Gold Coast service areas.
Key features include 130L storage capacity, 330L first hour capacity, 200L/hour hot water recovery, a 5 Star gas energy efficiency rating, patented Rheem Superflue® technology, mains-pressure delivery and a 10-year cylinder warranty subject to Rheem warranty terms.
What Does the Rheem Stellar 330 Do?
The Rheem Stellar 330 stores hot water in its cylinder and uses natural gas to recover the stored supply as hot water is used.
Unlike a continuous flow system, the Stellar 330 maintains a stored volume of hot water ready for household use while its gas burner provides rapid recovery during periods of demand.
This combination of storage and recovery gives the system its listed 330L first hour capacity.
Who Is the Rheem Stellar 330 Best For?
Family Homes
The Stellar 330 is designed for homes wanting strong gas storage recovery where several people may use hot water within a relatively short period.
Natural Gas Storage Replacement
It can suit homes replacing an existing outdoor natural gas storage water heater where the gas supply, plumbing, water pressure, location and clearances are suitable.
Customers Wanting Premium Gas Storage
The 5 Star rating, Superflue® technology and 200L/hour recovery position the Stellar 330 as a higher-performance gas storage option.
What Problems Can the Rheem Stellar 330 Help Solve?
Slow Recovery From an Older System
The listed 200L/hour recovery is designed to replenish hot water quickly as the stored supply is used.
Older Lower-Efficiency Gas Storage
The Stellar 330 carries a 5 Star gas energy efficiency rating and may be considered when replacing selected older 3 Star or 4 Star gas storage systems.
High Short-Term Hot Water Demand
The combination of stored water and rapid recovery provides a listed 330L first hour capacity for periods of concentrated household use.
Rheem Stellar 330 Key Details
Is the Rheem Stellar 330 Right for My Home?
A Good Choice If...
Your property uses natural gas, you want an outdoor storage system, need strong recovery and want mains-pressure hot water with high first hour capacity.
Consider Another Option If...
Your property uses LPG rather than natural gas, the system must be installed indoors, or you want to move away from gas storage to another hot water technology.
Check Before Ordering
Confirm gas type, natural gas supply, water pressure, gas connection, plumbing, valves, access, base condition, outdoor clearances and compliance requirements.
This Product Is for Natural Gas
This page is for the natural gas version of the Rheem Stellar 330.
The appliance must match the property's gas type. Natural gas and LPG systems are not interchangeable without selecting the correct product and completing appropriate licensed gas work.
If your existing water heater is connected to natural gas, this model follows the natural gas replacement pathway.
How Does the Rheem Stellar 330 Work?
1. Hot Water Is Stored
The system stores up to 130L of hot water inside its cylinder ready for household use.
2. Natural Gas Recovers the Supply
As hot water is drawn and cold water enters the cylinder, the natural gas burner rapidly reheats the incoming water.
3. Mains-Pressure Delivery
The system supplies mains-pressure hot water to connected household fixtures where the property's plumbing and pressure conditions are suitable.
Key Features of the Rheem Stellar 330
330L First Hour Capacity
The combination of stored hot water and fast gas recovery provides a listed 330L of first hour capacity.
200L/hour Recovery
The high recovery rate helps replenish hot water quickly during periods of stronger household demand.
5 Star Gas Efficiency
The Stellar 330 carries a listed 5 Star gas energy efficiency rating.
Rheem Superflue® Technology
Patented Rheem Superflue® technology forms part of the Stellar design and supports its gas storage performance and efficiency.
Mains-Pressure Hot Water
The system is designed to provide mains-pressure hot water to multiple taps where the home's plumbing and pressure conditions are suitable.
Australian Made
The supplied product information identifies the Rheem Stellar 330 gas water heater as Australian made.

Why Is It Called the Rheem Stellar 330 if the Tank Is 130L?
The 330 in Rheem Stellar 330 refers to the system's listed 330L first hour capacity, not the physical storage capacity of the cylinder.
The cylinder stores 130L, while the gas burner continues reheating incoming water as hot water is used. Combining the stored volume with recovery performance results in the larger first hour figure.
This is particularly relevant where several showers or other hot water uses occur close together.
What Does 200L/hour Recovery Mean?
The Rheem Stellar 330 is listed with 200L/hour hot water recovery.
Recovery describes how quickly the system can replace hot water after it has been drawn from the cylinder. Faster recovery can help support family routines where multiple people use hot water within a short period.
Actual household performance can vary with incoming water temperature, usage, plumbing and operating conditions.
How Efficient Is the Rheem Stellar 330?
The Rheem Stellar 330 has a listed 5 Star gas energy efficiency rating.
This positions it above many older 3 Star and 4 Star gas storage systems on rated gas efficiency.
Actual running costs depend on natural gas pricing, household hot water consumption, climate, thermostat operation, installation condition and usage patterns.
What Is Rheem Superflue® Technology?
The Rheem Stellar 330 includes patented Rheem Superflue® technology.
This technology forms part of the Stellar gas storage design and supports the system's high gas efficiency and recovery performance.
It is one of the features that distinguishes the Stellar range from more basic gas storage replacement models.
Does the Rheem Stellar 330 Provide Mains-Pressure Hot Water?
Yes. The Rheem Stellar 330 is designed to provide mains-pressure hot water.
This helps support strong hot water delivery to multiple outlets where the property's incoming pressure, pipework and fixtures are suitable.
Can the Rheem Stellar 330 Be Installed Indoors?
No. The supplied product information identifies the Rheem Stellar 330 as designed for outdoor installation.
The installation position must comply with Rheem requirements, applicable gas fitting rules, ventilation and clearance requirements and other relevant installation standards.
Rheem Stellar 330 Water Pressure Requirements
The supplied specifications list a 1400 kPa relief valve pressure and a 1200 kPa expansion control valve setting.
The listed maximum water supply pressure is 960 kPa with an ECV fitted and 1120 kPa without an ECV.
Incoming water pressure and the existing valve arrangement should be checked before installation. Additional valves or pressure control may be required depending on the site.
Rheem Stellar 330 Natural Gas Supply Requirements
The supplied specifications list a gas consumption of 42 MJ/hr and an Rp 1/2 gas connection.
The natural gas supply and existing gas pipework must be suitable for the appliance demand and installation position.
Any required gas fitting work should be completed by an appropriately licensed gas fitter.
How Is the Rheem Stellar 330 Cylinder Protected?
The supplied product information lists two anodes in the Rheem Stellar 330.
The anodes form part of the cylinder protection system and should be maintained in accordance with Rheem's servicing and warranty requirements.
What Is Required to Install the Rheem Stellar 330?
- Confirmed natural gas supply
- Suitable outdoor installation position
- Natural gas connection suitable for the appliance
- Compatible hot and cold water pipework
- Suitable water pressure
- Correct valve arrangement
- Compliant pressure-relief discharge
- Suitable level and structurally adequate base
- Required gas appliance clearances
- Adequate ventilation and surrounding conditions
- Adequate service access
- Any required gas or plumbing compliance work
- Old-system removal where selected
- Installation by appropriately licensed trades
Can the Rheem Stellar 330 Replace My Existing Gas Hot Water System?
The Rheem Stellar 330 can be a strong replacement option where the existing water heater is natural gas, the installation position is outdoors and the gas supply, water pressure, plumbing, base, clearances and access are suitable.
Replacement should not automatically be assumed to be like-for-like. Valve condition, gas fitting requirements, pipework and compliance should still be assessed.
Replacing an Older 3 Star or 4 Star Gas Storage System
The Stellar 330 may suit customers wanting to retain gas storage hot water while moving to a 5 Star model with strong recovery performance.
Replacing an LPG System
This natural gas model should not be selected simply because the existing appliance is gas. The property's gas type must be confirmed before ordering.
Relocating the System
Moving the water heater to another position can require additional gas pipework, plumbing, base preparation, drainage and compliance work.
Rheem Stellar 330 vs Rheem 4 Star 170L Gas Storage
| Feature | Rheem Stellar 330 | Rheem 4 Star 170L |
|---|---|---|
| Gas Efficiency | 5 Star | 4 Star |
| Storage Capacity | 130L | Larger storage capacity |
| First Hour Capacity | 330L | Lower than the Stellar 330 |
| Hourly Recovery | 200L/hour | Lower than the Stellar 330 |
| Positioning | Premium high-recovery gas storage | Standard 4 Star gas storage |
The Stellar 330 prioritises rapid recovery, strong first hour performance and 5 Star gas efficiency, while the Rheem 4 Star 170L provides a larger physical storage cylinder. Suitability depends on household demand, existing gas setup, installation requirements and preferred storage-versus-recovery balance.

Why Buy the Rheem Stellar 330 From Installed Today?

Is the Rheem Stellar 330 Right for You?

Before ordering, confirm that the property uses natural gas, the intended installation position is outdoors and the gas supply, water pressure, plumbing, valves, base, clearances and access are suitable. Choose supply only if appropriately licensed trades are already arranged, or select an eligible Brisbane or Gold Coast supply and installation option where available.
Tempering valve information:
Where a hot water system is capable of delivering water above 50°C, a compliant tempering valve must be installed to control the temperature delivered to personal hygiene fixtures such as showers, baths, basins, and bathroom outlets. This helps reduce the risk of scalding and assists with meeting plumbing compliance requirements.
A tempering valve blends hot and cold water to deliver a safer controlled outlet temperature to required fixtures. The hot water unit itself may store water at a higher temperature, but the water delivered to personal hygiene outlets must be controlled where required by plumbing regulations.
If your property already has a suitable, compliant tempering valve installed, your licensed plumber can assess whether it is appropriate for use with the new hot water system. Existing valves may not always be suitable due to age, condition, compliance requirements, valve type, location, or system compatibility.
If a compliant tempering valve is not already installed, or if the existing valve is unsuitable, one must be supplied and installed by a licensed plumber as part of the hot water installation.
Tempering valves are not automatically included with every supply-only hot water unit unless specifically selected, listed as included, or purchased as part of a suitable valve kit. If a tempering valve is required, please purchase the appropriate valve kit with your order or arrange for your licensed installer to supply and install the correct tempering valve on site.
It is the customer’s responsibility to ensure the installation is completed by appropriately licensed trades and that all required valves, fittings, electrical work, plumbing work, and compliance requirements are allowed for as part of the installation.
