Supply Only 5-Star Gas Hot Water Systems Across Australian Metro Areas
Supply only is ideal if you already have a licensed gas fitter or plumber ready to install your new 5-star gas hot water system. This option suits homeowners managing their own trade, builders ordering for a project, property managers arranging a replacement, and trade customers who only need the unit supplied.
The product price is for the gas storage hot water system only. Installation, valves, old unit removal, disposal, gas work, electrical work, pipework changes, tempering valves, drainage work, access upgrades, compliance upgrades and gas compliance work are not included unless selected separately.
Before ordering supply only, check that the gas storage system suits the property, gas type, household demand, available space, installation location, access path, connection positions and compliance requirements. This is especially important when replacing an older gas storage tank, switching between natural gas and LPG, changing storage size, or comparing a 5-star storage unit against instant gas hot water.
Supplied and Installed 5-Star Gas Hot Water Systems in Brisbane and Gold Coast
Supplied and installed options are available on selected 5-star gas hot water systems in eligible Brisbane and Gold Coast service areas. This option is designed for customers who want the product and installation organised together instead of buying the unit separately.
Supplied and installed can be useful when an existing gas storage system has failed, when a family home needs a practical replacement, or when a customer wants to stay with a storage-style gas hot water system while choosing a higher-efficiency 5-star model.
Availability depends on your address, existing system, gas type, installation location, site access, plumbing setup, gas supply, drainage and current compliance needs. Some jobs may need additional valves, disposal, gas pipework, pipework changes, drainage changes, tempering valve upgrades or compliance work depending on the property.
What Is a 5-Star Gas Hot Water System?
A 5-star gas hot water system is a gas storage hot water unit designed to provide stored hot water with a higher energy efficiency rating than lower-rated gas storage models in the same general category.
Unlike instant gas hot water systems, which heat water as it flows through the unit, a 5-star gas storage system heats and stores water inside a tank. This gives the home a ready supply of hot water for showers, taps, baths, kitchens, laundries and everyday household use.
Storage-style gas hot water remains a practical option for many homes, especially where the existing setup is already gas storage and the customer wants a familiar like-for-like replacement without changing to continuous flow.
Storage Style Only: Not Instant Gas
This collection is for storage-style gas hot water systems only.
That means the systems in this range store heated water inside a tank. They are different from instant gas hot water systems, also known as continuous flow gas hot water systems.
A gas storage system may suit customers who want to replace an existing gas storage unit with another tank-style model.
An instant gas system may suit customers who want a compact wall-mounted unit that heats water on demand.
Both system types can be useful, but they are not the same. If your current hot water system is a gas storage tank and you want the simplest replacement path, a 5-star gas storage model may be worth comparing.
Who Should Choose a 5-Star Gas Storage Hot Water System?
A 5-star gas storage hot water system may suit family homes, townhouses, rental properties, small to medium households and customers replacing an existing external gas storage unit.
It can also suit customers who prefer a tank-style gas hot water system but want to compare higher-efficiency storage models rather than choosing a basic replacement.
A 5-star gas storage system may be suitable where:
The property already has gas storage hot water
The home uses natural gas or LPG
The existing tank-style setup has worked well
The customer wants a familiar replacement style
A storage system is preferred over continuous flow
The household has moderate daily hot water demand
The installation location suits an external gas storage unit
A 5-star gas storage system may not be the best option where:
The property has no suitable gas supply
The customer wants a wall-mounted instant gas unit
The home has very high peak hot water demand
The property needs continuous flow performance
The existing site does not suit a storage tank
A different energy type would better suit the home
The best system depends on the existing setup, gas type, household demand, installation location and overall replacement requirements.
Natural Gas and LPG 5-Star Gas Hot Water Systems
5-star gas storage hot water systems may be available in natural gas and LPG versions, depending on the brand and model. The correct gas type must be selected before ordering.
Natural gas models are designed for properties connected to a natural gas supply. These are common in many metro areas where mains gas is available.
LPG models are designed for properties using bottled LPG. These may suit homes without natural gas access, acreage properties, rural homes, granny flats, secondary dwellings and selected outdoor installations where LPG is already available.
Natural gas and LPG models are not interchangeable. Ordering the wrong gas type can delay installation and may require product exchange or additional work. If you are unsure, check the label on the existing unit or confirm the gas type with your licensed gas fitter before ordering.
5-Star Gas Storage Size Guide
5-star gas storage systems are generally compared by tank capacity, gas type, recovery performance, dimensions and installation suitability.
Smaller gas storage systems may suit compact homes, couples, townhouses, units and lower-demand properties.
Medium gas storage systems may suit small to medium families, rental properties and everyday replacement jobs where the existing system has performed well.
Larger gas storage systems may suit family homes, higher-use households and properties where a smaller tank may not provide enough stored hot water.
The right size depends on the number of people in the home, number of bathrooms, shower habits, bath use, laundry demand, recovery rate, gas type and whether the current system has been keeping up with daily use.
If the existing gas storage system regularly runs out of hot water, replacing it with the same size may not solve the issue. A larger storage model or an instant gas system may be worth comparing depending on the property.
5-Star Gas Storage vs Standard Gas Storage
A 5-star gas storage hot water system is designed to offer a higher energy rating than lower-rated gas storage systems in the same general category.
A standard gas storage system may still suit some customers, especially where the priority is the lowest upfront replacement cost or a close match to the existing unit.
A 5-star gas storage system may be worth comparing where the customer wants to stay with tank-style gas hot water while choosing a more efficient model.
The better choice depends on the budget, existing system, gas type, household demand, installation location and long-term priorities. The energy rating is important, but it should be considered alongside size, recovery, dimensions, warranty, connection positions and installation suitability.
5-Star Gas Storage vs Instant Gas Hot Water
A 5-star gas storage hot water system stores heated water inside a tank, ready for use when needed. It can be a practical choice when replacing an existing gas storage unit and the customer wants to stay with a familiar tank-style system.
An instant gas hot water system heats water as it flows through the unit. It is usually wall-mounted outside and is compared by flow rate, such as 16L, 20L or 26L, rather than tank capacity.
Gas storage may be better where the existing tank setup has worked well and the customer wants a straightforward replacement.
Instant gas may be better where the customer wants a compact wall-mounted system, continuous flow performance, or a different style of gas hot water setup.
Changing from gas storage to instant gas may involve gas pipework, wall mounting, plumbing changes, electrical work, drainage changes, valve upgrades and compliance work. These extras are not included in the product price unless selected separately.
5-Star Gas Storage vs Electric Hot Water
A 5-star gas storage hot water system uses natural gas or LPG to heat stored water in a tank. An electric storage hot water system uses electricity to heat stored water.
A 5-star gas storage system may suit homes already set up for gas hot water, especially where the existing gas storage unit has worked well and the customer wants to stay with gas.
Electric storage may suit homes already set up for electric hot water or customers wanting a simpler electric replacement path.
Changing from gas to electric, or electric to gas, is not usually a simple product swap. The property may need gas work, electrical work, pipework changes, disconnection or capping of services, valve changes and compliance checks.
The best choice depends on the existing setup, energy source, household demand, installation location, budget and site requirements.
Outdoor Installation for 5-Star Gas Storage Systems
Most standard residential gas storage hot water systems are external outdoor models unless the product is specifically designed and approved as an internal or flued indoor appliance.
External gas storage systems are commonly installed beside the home, near an existing service area, in a side passage, near a laundry wall or in another compliant outdoor location.
Before ordering, check the system’s dimensions, location, clearances, gas pipework, water connections, drainage, access, ventilation and compliance requirements.
Do not assume an external gas storage unit can be installed indoors. Indoor gas installations require the correct appliance type, flueing, ventilation and compliance setup. The product specifications and licensed installer should confirm suitability before ordering.
Replacing an Existing Gas Storage System with a 5-Star Model
If your existing gas storage hot water system has worked well, replacing it with a similar storage-style system can often be a practical option.
A 5-star model may be worth comparing if you want to stay with gas storage while choosing a higher-efficiency option. This can be useful where the home is already set up for gas storage and the customer does not want to change to instant gas or another energy type.
Before choosing a replacement, check the old system’s gas type, tank size, brand, model, installation location, connection points, valve condition, drainage, access and gas supply.
A replacement is also a good time to consider whether the current size still suits the property. A growing family may need a larger system. A smaller household may not need the same stored volume. A rental property may prioritise practical replacement, brand reliability and simple ongoing use.
5-Star Gas Hot Water Brands Available
Installed Today stocks selected 5-star gas hot water systems from trusted brands, depending on product availability. Across the broader gas storage range, this may include brands such as Rheem, Rinnai, Vulcan, Dux and Aquamax.
When comparing 5-star gas hot water systems, look beyond the energy rating alone. Check the gas type, storage capacity, warranty, dimensions, connection positions, recovery performance, outdoor installation requirements, household suitability and whether the model is a practical replacement for your existing system.
Some customers want a higher-efficiency storage replacement. Others want a known brand, a natural gas model, an LPG model, a family-sized tank, or a product that closely matches the old system. The best choice depends on the property, budget and reason for replacement.
5-Star Gas Hot Water System Buying Guide
What does 5-star gas hot water mean?
A 5-star gas hot water system refers to a gas hot water unit with a 5-star energy rating in its product category. For this collection, it means storage-style gas hot water systems only, not instant gas continuous flow models.
The rating can help customers compare gas storage options, but it should be considered alongside tank size, gas type, household demand, installation location and replacement suitability.
Is a 5-star gas storage system better than standard gas storage?
A 5-star gas storage system may be better for customers who want to stay with tank-style gas hot water while choosing a higher-efficiency model.
A standard gas storage system may still be suitable where the customer wants the lowest upfront replacement cost or a closer match to an older unit.
The better choice depends on budget, gas type, household demand, product size, warranty and installation requirements.
Is this the same as instant gas hot water?
No. This collection is for storage-style gas hot water systems only. A gas storage system heats and stores hot water inside a tank.
Instant gas hot water systems heat water as it flows through the unit and are usually wall-mounted. They are compared by flow rate, not tank capacity.
Should I choose natural gas or LPG?
Choose natural gas if your property is connected to natural gas and the selected model is designed for natural gas. Choose LPG if your property uses bottled LPG and the selected model is designed for LPG.
Natural gas and LPG models are different, so the correct version must be ordered. If you are unsure, check the existing unit label or confirm the gas type with your licensed gas fitter.
Can I replace my old gas storage system with a 5-star model?
Replacing an old gas storage system with a 5-star model may be possible if the new system suits the gas type, size, installation location, connection positions and site requirements.
It can be a practical option where the customer wants to stay with gas storage but compare a higher-efficiency replacement. The replacement still needs to meet current clearances, valve, drainage and compliance requirements.
Can I change from gas storage to instant gas instead?
Changing from gas storage to instant gas may be possible, but it is not always a simple swap. Instant gas systems have different gas supply, water connection, wall mounting, electrical and drainage requirements.
The job may involve gas pipe upgrades, plumbing changes, valve upgrades, electrical work, disposal, wall mounting and compliance work. These extras are not included in the product price unless selected separately.
Are 5-star gas storage systems suitable for rental properties?
5-star gas storage systems can suit some rental properties, especially where the home already has a gas storage unit and the owner wants a practical higher-efficiency replacement.
For rentals, the best system should match tenant demand, property layout, gas type, installation location and long-term practicality. A smaller rental may suit a smaller storage unit, while a larger family rental may need a larger tank or another gas hot water option.
What should I check before buying a 5-star gas hot water system online?
Before buying a 5-star gas hot water system online, check the gas type, tank size, installation location, dimensions, connection positions, clearances, gas supply, access path, drainage, valve condition and whether the property may need extra gas work, pipework changes or compliance upgrades.
For supply only, your licensed gas fitter or plumber should confirm suitability before installation. For supplied and installed options in Brisbane and Gold Coast, the product page questions help identify common installation requirements before checkout.
Can a 5-star gas storage system be installed indoors?
Most standard residential gas storage hot water systems are external outdoor units unless the product is specifically designed and approved for indoor or flued installation.
Do not install an external gas unit indoors. Indoor gas installations require the correct appliance, flueing, ventilation and compliance setup.
