Who Is the Vulcan 170L Natural Gas Best For?
Medium to Large Families
Vulcan lists the 170L gas storage model for up to 6 people under stated usage conditions. Actual suitability depends on climate, showers, fixture flow rates and household routines.
Homes Connected to Natural Gas
This model is specifically for mains natural gas and should be matched to a suitable gas supply, meter capacity and pipe sizing.
Gas Storage Replacement
The 170L model can suit selected replacements of older outdoor natural gas storage systems where the gas supply, plumbing, base, access and clearances are suitable.
What Problems Can the Vulcan 170L Natural Gas Help Solve?
135L Capacity Too Small
The 170L model provides more stored hot water than the Vulcan 135L and may better suit households with stronger daily hot water demand.
Replacing an Older Gas Storage Unit

Is the Vulcan 170L Natural Gas Right for My Home?
A Good Choice If...
Your property is connected to mains natural gas, you want an outdoor 170L gas storage system and your household has medium to large hot water demand.
Consider Another Option If...
Your property uses LPG, you need an indoor installation, or your household would be better suited to a smaller storage system, larger-capacity option or continuous flow system.
Check Before Ordering
Confirm gas type, gas meter suitability, gas pipe sizing, water pressure, valve requirements, base condition, outdoor clearances, plumbing and access.
This Product Is for Natural Gas
The current Vulcan 170L gas storage model is listed as natural gas only.

How Does the Vulcan 170L Natural Gas Work?
1. Hot Water Is Stored
The system stores 170L of heated water inside its vitreous enamel lined cylinder ready for household use.
2. Hot Water Is Drawn
When a hot tap is opened, stored hot water leaves the cylinder and incoming cold water replaces it.

How Much Hot Water Does the Vulcan 170L Natural Gas Store?
The Vulcan 170L Natural Gas stores 170 litres of hot water.
This provides more stored volume than the 135L model, with natural gas recovery to reheat the cylinder after hot water is drawn.

How Many People Does the Vulcan 170L Natural Gas Suit?
Vulcan lists the 170L gas storage model as suitable for up to 6 people under its stated conditions.
The supplied guidance is based on 7-minute showers at 42°C mixed water temperature in a moderate climate with the thermostat at maximum setting.
Actual household suitability can vary considerably depending on shower duration, bath use, fixture flow rates, climate and total daily hot water consumption.
How Efficient Is the Vulcan 170L Natural Gas?
The Vulcan 170L Natural Gas has a listed 4 Star gas energy rating.
Gas storage water heaters can be a practical replacement where a home already has a natural gas storage system installed and the customer wants to stay with the same general hot water technology.
Actual running costs depend on natural gas pricing, household hot water use, thermostat settings, recovery demand, climate and installation condition.
How Is the Vulcan 170L Cylinder Protected?
The Vulcan 170L Natural Gas uses a vitreous enamel lined cylinder.
The lining is designed to help protect the inside of the storage tank during normal hot water service.
Water quality, pressure control, valve selection, correct installation and ongoing maintenance all play a role in the service life of a storage water heater.
Can the Vulcan 170L Natural Gas Be Installed Indoors?
No. The Vulcan 170L Natural Gas storage water heater is listed for outdoor installation only.
The installation must meet applicable outdoor clearance, ventilation, flue terminal, base, access, gas, plumbing and compliance requirements.
Vulcan 170L Natural Gas Supply Requirements
The supplied specifications list natural gas consumption at 27 MJ/hour.
A licensed gas fitter should confirm gas meter suitability, gas pipe sizing, appliance location and compliance requirements before installation.

Vulcan 170L Natural Gas Water and Gas Connections
The Vulcan 170L uses Rp 3/4 left-hand water connections and a listed 1/2 RP gas connection.
Connection position matters in replacement work because existing pipework can affect labour, parts required and whether plumbing or gas alterations are necessary.
Is a Trim Kit Available for the Vulcan 170L?
Yes. Vulcan lists the FK170 trim kit for the 170L gas storage model.
A trim kit may be useful in selected installations depending on the existing setup and desired finish. It is not included unless selected separately.
How Big Is the Vulcan 170L Natural Gas?
The supplied dimensions are approximately 1868 mm high × 422 mm wide × 502 mm deep.

Replacing an Existing 170L Unit
The Vulcan 170L may suit selected same-capacity replacement applications where the existing position, connections, gas supply and installation conditions are compatible.
Relocating the System
Moving the system from its current position can require additional gas pipework, plumbing, base preparation, clearance assessment and compliance work.
Vulcan 170L Natural Gas vs Vulcan 135L Natural Gas
| Feature | Vulcan 135L Natural Gas | Vulcan 170L Natural Gas |
|---|---|---|
| Storage Capacity | 135L | 170L |
| Relative Household Demand | Small to medium | Medium to large |
| Vulcan Household Guide | Up to 5 under stated conditions | Up to 6 under stated conditions |
| Main Reason to Consider | Smaller storage footprint | Greater stored hot water capacity |
The 170L model provides more stored hot water than the 135L version and may better suit larger households, stronger shower demand or homes replacing an existing 170L-class gas storage system.
Vulcan 170L Natural Gas vs LPG
Current 170L Natural Gas Model
The supplied product information lists the current Vulcan 170L gas storage model as natural gas only.
Older LPG Variants
Older LPG variants may have existed historically, but they should be treated as separate gas-specific products and not as interchangeable with the current natural gas model.
Always confirm the property's actual gas supply and the appliance data plate before ordering.
Vulcan 170L Natural Gas Storage vs Natural Gas Continuous Flow
170L Gas Storage
Stores 170L of hot water ready for use and reheats the cylinder with natural gas after hot water is drawn.
Natural Gas Continuous Flow
Heats water on demand without a storage cylinder and must be correctly sized for flow rate, gas supply and simultaneous fixture use.
Storage may suit customers wanting a familiar replacement for an existing gas storage system, while continuous flow may suit customers wanting compact wall-mounted on-demand heating.
Vulcan 170L Natural Gas vs Electric Storage
Natural Gas Storage
Uses mains natural gas to heat stored water and may suit properties already connected to gas and replacing an existing gas storage water heater.
Electric Storage
Uses an electric element and may suit properties without gas supply or where an electrical replacement better matches the existing installation.
Existing infrastructure, energy source, household demand, installation cost, running costs and compliance requirements should all be considered before changing hot water system type.

Why Buy the Vulcan 170L Natural Gas From Installed Today?
Installed Today gives customers a straightforward way to purchase the Vulcan 170L Natural Gas as a supply-only gas storage water heater or select an eligible supplied-and-installed package in Brisbane or the Gold Coast where available.
Is the Vulcan 170L Natural Gas Right for You?
The Vulcan 170L Natural Gas Storage Hot Water System is primarily suited to medium to large households connected to mains natural gas that want an outdoor storage water heater with 170L stored capacity, gas recovery, a 4 Star rating and vitreous enamel cylinder construction.
Before ordering, confirm that the property uses natural gas rather than LPG, the intended installation position is outdoors and the gas meter, gas pipe sizing, water pressure, valves, base, connections, 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.
