Supply Only 160/170L 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 160L or 170L 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 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, changing brands, switching between natural gas and LPG, or comparing a larger storage system against instant gas hot water.
Supplied and Installed 160/170L Gas Hot Water Systems in Brisbane and Gold Coast
Supplied and installed options are available on selected 160L and 170L 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 the property already has a similar gas storage unit and the customer wants to stay with a familiar storage-style setup.
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 160/170L Gas Hot Water System?
A 160L or 170L gas hot water system is a gas storage hot water unit that heats and stores water inside a tank. Unlike instant gas systems, which heat water as it flows through the unit, a gas storage system keeps a set volume of hot water ready for use.
These systems are commonly used as practical replacements for older external gas storage units. They can suit homes where the existing gas storage setup has worked well and the customer wants to stay with a tank-style gas hot water system.
A 160L or 170L gas storage unit generally provides more stored hot water than smaller 130L or 135L gas systems, making it better suited to family homes, larger rentals and households with higher daily hot water use.
Who Should Choose a 160L or 170L Gas Hot Water System?
A 160L or 170L gas hot water system may suit family homes, small to medium families, rental properties, homes with one or two bathrooms, households with regular shower use and properties where a smaller gas storage system may not provide enough stored hot water.
It can also suit customers replacing an existing 160L, 170L or similar gas storage system that has reached the end of its service life. If the old unit supplied enough hot water and suited the installation location, another similar-sized gas storage system may be a practical replacement.
For smaller homes, couples, townhouses or lower-use properties, a 130L or 135L gas storage system may be enough. For homes with heavier demand, multiple bathrooms or frequent back-to-back showers, instant gas hot water or a larger-capacity solution may be worth comparing.
Natural Gas and LPG 160/170L Gas Hot Water Systems
160L and 170L gas 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. They are common in many metro areas where mains gas is available.
LPG models are designed for properties using bottled LPG. They 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 the same. 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.
160/170L Gas Storage Size Guide
A 160L or 170L gas storage system provides a larger stored volume than compact gas storage units and can suit homes with regular daily hot water demand. It can be a practical choice where the household wants gas storage rather than instant gas hot water.
A 160L or 170L gas hot water system may be suitable for:
Family homes
Small to medium families
Rental properties
Homes with one or two bathrooms
Properties replacing an existing 160L or 170L gas storage tank
Households with regular shower use
Homes needing more capacity than 130L or 135L
Properties where gas storage has worked well
Customers wanting a tank-style gas hot water replacement
A 160L or 170L gas hot water system may not be suitable for:
Very large families
Homes with several bathrooms
Heavy back-to-back shower use
High bath use
Shared homes with several occupants
Properties needing continuous high-volume hot water
Homes where an instant gas system may be more suitable
If the current system has regularly run out of hot water, replacing it with the same size may not solve the issue. In that case, instant gas hot water or a different system type may be worth comparing.
160L vs 170L Gas Hot Water Systems
160L and 170L gas hot water systems sit in a similar larger gas storage size range. The exact size available usually depends on the brand, product series, gas type and current stock.
A 160L gas hot water system may suit customers replacing an existing similar-sized unit or wanting a larger gas storage option for everyday family use.
A 170L gas hot water system may also suit family homes and rental properties where a higher stored volume is preferred compared with smaller gas storage tanks.
When comparing 160L and 170L systems, focus on the gas type, dimensions, warranty, connection positions, recovery performance, installation location and whether the new unit is a practical match for the existing site.
160/170L vs 130/135L Gas Hot Water Systems
A 130L or 135L gas hot water system can suit smaller homes, townhouses, couples, compact families and moderate-use properties. It may be enough where daily demand is lower and the home has one bathroom.
A 160L or 170L gas hot water system provides more stored hot water and may be better suited to family homes, higher-use rentals and households that need a stronger storage buffer for daily use.
The right choice depends on the number of people in the home, shower habits, bath use, laundry demand, number of bathrooms and whether the existing system has been keeping up.
160/170L Gas Storage vs Instant Gas Hot Water
A 160L or 170L gas storage hot water system stores heated water in 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 system style.
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 when the current storage setup has worked well and the customer wants a straightforward replacement. Instant gas may be worth comparing where the customer wants a compact wall-mounted unit, stronger continuous flow performance, or an upgrade from a storage tank.
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.
160/170L Gas Storage vs Electric Hot Water
A gas storage hot water system uses natural gas or LPG to heat stored water in a tank. An electric storage system uses electricity to heat stored water.
A 160L or 170L gas storage system may suit homes already set up for gas hot water, especially where the existing gas storage unit has worked well. 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 160/170L Gas Hot Water Systems
Most residential gas storage hot water systems sold for standard replacement 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 160/170L Gas Hot Water System
If your existing 160L or 170L gas hot water system has worked well, replacing it with another similar-sized gas storage unit can often be a practical option. This can help keep the replacement close to the existing setup, especially when the old unit suited the property’s hot water demand.
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 different option. A smaller household may not need the same stored volume. A rental property may prioritise practical replacement, brand reliability and simple ongoing use.
160/170L Gas Hot Water Brands Available
Installed Today stocks selected 160L and 170L 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 160L and 170L gas hot water systems, look beyond the brand name. 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 budget-friendly replacement. Others want a known brand, a tough storage unit, a natural gas model, an LPG model, or a product that closely matches the old system. The best choice depends on the property, budget and reason for replacement.
160/170L Gas Hot Water System Buying Guide
Is a 160L or 170L gas hot water system enough for a family?
A 160L or 170L gas hot water system can suit many small to medium families, especially where the home has one or two bathrooms and regular daily hot water use.
For larger families, multiple bathrooms, long back-to-back showers or regular bath use, an instant gas system or another hot water option may be worth comparing.
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 170L gas system with the same size?
Replacing an old 170L gas hot water system with another similar-sized model can be practical if the old unit supplied enough hot water for the property. It may also help simplify the replacement when the new system has similar dimensions and connection positions.
However, the replacement still needs to suit the current site. Gas type, clearances, valve condition, drainage, access, connection positions and compliance requirements should all be checked before installation.
Is 160L or 170L gas storage better than 130L or 135L?
A 160L or 170L gas storage system provides more stored hot water than a 130L or 135L model. It may be better for family homes, higher-use rentals or properties where a smaller gas storage tank may run short during peak use.
A 130L or 135L system may still be suitable for smaller homes, lower-use households and properties where the current smaller tank has performed well.
Is gas storage better than instant gas hot water?
Gas storage may be better if the property already has a gas storage unit and the customer wants a familiar like-for-like replacement. It stores hot water in a tank and can be a straightforward option when the existing setup has worked well.
Instant gas may be better where the customer wants a wall-mounted continuous flow system and the property has suitable gas supply, water pressure and installation conditions. The best option depends on the home, budget, gas setup and hot water demand.
Can I change from gas storage to instant gas?
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 160L and 170L gas hot water systems suitable for rentals?
160L and 170L gas hot water systems can suit many rental properties, especially family homes and properties with moderate occupant numbers.
For smaller rentals, a 130L or 135L gas storage system may be enough. For larger rentals or shared homes, instant gas or another larger-capacity solution may be more suitable. The best option should match tenant demand, property layout, gas type, installation location and long-term practicality.
What should I check before buying a 160L or 170L gas hot water system online?
Before buying a 160L or 170L 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 gas storage hot water 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.
