Quick Specifications

Natural Gas Storage Hot Water

The Vulcan 170L Natural Gas model is designed for homes connected to mains natural gas.

This may suit:

• properties already using natural gas for hot water

• homes replacing older gas storage systems

• locations preferring a traditional external storage unit

Because this is the natural gas model, it must be matched to a suitable natural gas supply.

Natural gas and LPG appliances are not interchangeable and the gas type should be confirmed before installation.

170L Storage Capacity

The Vulcan 170L Natural Gas stores 170L of hot water.

This provides a larger stored volume than the 135L model, with gas recovery reheating the cylinder after hot water is drawn.

Vulcan lists the 170L gas storage model as suitable for up to 6 people based on stated usage assumptions.

Actual suitability depends on:

• shower duration

• water temperature

• climate conditions

• outlet flow rates

• bath usage

• laundry demand

• household routines

4 Star Gas Energy Rating

The Vulcan 170L Natural Gas has a 4 Star gas energy rating.

Gas storage water heaters are commonly selected where a home already has a gas storage system installed and the customer wants a practical replacement.

Running costs depend on:

• natural gas pricing

• household hot water demand

• thermostat settings

• recovery demand

• installation quality

• climate conditions

Vitreous Enamel Lined Cylinder

The Vulcan 170L Natural Gas uses a vitreous enamel lined cylinder designed to help protect the inside of the tank.

Correct installation, pressure control, valve selection and ongoing maintenance all contribute to long-term gas storage hot water performance.

Water quality and installation conditions can also affect service life.

Outdoor Installation Only

The Vulcan 170L Natural Gas storage water heater is suitable for outdoor installation only.

It should not be installed indoors.

Outdoor gas storage systems require:

• suitable clearances

• ventilation

• flue terminal positioning

• base support

• access

• compliant gas and plumbing connections

Installation suitability should be checked before installation.

Natural Gas Supply Requirements

The Vulcan 170L Natural Gas lists:

• hourly natural gas consumption of 27 MJ

A licensed gas fitter should confirm:

• gas meter suitability

• gas pipe sizing

• appliance location

• regulator setup

• compliance requirements

before installation.

Gas supply issues can affect:

• performance

• safety

• installation complexity

• final installation cost

Water Pressure Requirements

The Vulcan 170L Natural Gas lists:

• relief valve setting of 1400 kPa

• ECV setting of 1200 kPa

• maximum supply pressure of 960 kPa with ECV

• maximum supply pressure of 1120 kPa without ECV

If incoming water pressure is too high, pressure control may be required.

Valve requirements should be checked before installation, especially when replacing older units where existing valves may be worn, missing or non-compliant.

Left Handed Water Connections

The Vulcan 170L gas storage model uses Rp 3/4 left hand water connections.

Connection position matters for replacement installations because existing pipework can affect:

• installation time

• required fittings

• pipework alterations

• installation complexity

The supplied model and existing pipework should be checked before installation.

Trim Kit Option

Vulcan lists the FK170 trim kit for the 170L gas storage model.

A trim kit may be useful in some installations depending on:

• the existing setup

• wall finish requirements

• replacement presentation

• installation access

Vulcan 170L Natural Gas vs Vulcan 135L Natural Gas

The Vulcan 170L Natural Gas provides more stored hot water capacity than the Vulcan 135L Natural Gas model.

The 135L model may suit:

• smaller households

• lower hot water demand

• tighter installation spaces

The 170L model may better suit:

• medium to large families

• stronger shower usage

• homes replacing an existing 170L gas storage unit

The correct size depends on:

• outlet flow rates

• climate conditions

• hot water habits

Vulcan 170L Natural Gas vs LPG Model

The current Vulcan 170L gas storage model is listed as natural gas only.

Natural gas and LPG appliances are not interchangeable.

Even where older LPG variants may have existed historically, a current replacement should always be checked against:

• gas type

• model plate

• supplier availability

• compliance requirements

before ordering.

Vulcan 170L Natural Gas vs Continuous Flow Natural Gas

The Vulcan 170L Natural Gas stores hot water in a tank, while a natural gas continuous flow system heats water as it passes through the unit.

A gas storage system may suit homeowners replacing an existing gas storage unit and wanting a familiar storage-style setup.

A continuous flow system may suit homeowners wanting:

• a compact wall-mounted unit

• on-demand heating

• continuous operation without stored tank water

The best option depends on:

• existing system setup

• household usage

• natural gas supply

• available space

• hot water demand

• installation requirements

Vulcan 170L Natural Gas vs Electric Storage

The Vulcan 170L Natural Gas uses natural gas for heating, while an electric storage system uses an electric element.

Natural gas storage may suit:

• properties already connected to mains gas

• homes replacing existing gas storage systems

• households preferring gas hot water recovery

Electric storage may suit:

• homes without gas supply

• straightforward electric replacements

• properties with simpler electrical upgrade pathways
