Quick Specifications

Vitreous Enamel Lined Cylinder

The Vulcan 315L uses a vitreous enamel lined cylinder designed to help protect the internal tank surface.

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

Water quality and installation conditions can also affect service life.

Large 315L Storage Capacity

The 315L capacity may suit medium to large family homes with stronger daily hot water demand.

This size may suit:

• larger households

• homes with multiple occupants

• family homes

• rental properties

• investment homes

• households using significant daily hot water

The correct system size still depends on:

• shower usage

• occupant numbers

• laundry demand

• climate conditions

• outlet flow rates

• daily usage patterns

Single Element Electric Heating

The Vulcan 315L is a single element electric storage water heater available in:

• 3.6 kW variants

• 4.8 kW variants

Electrical suitability should be checked before installation.

Electrical work, circuit upgrades, isolator changes and compliance upgrades are not included unless separately arranged.

Off-Peak Tariff Suitability

The Vulcan 315L is listed as suitable for connection to off-peak tariff.

This may suit larger households wanting to heat stored water during off-peak electricity periods for later household use.

Tariff suitability, recovery time and household demand should still be checked before installation.

Indoor or Outdoor Installation

The Vulcan 315L may be installed indoors or outdoors where suitable.

Indoor installations may require:

• safe trays

• compliant drainage

• leak protection

• service access

Outdoor installations require:

• suitable weather exposure conditions

• plumbing access

• base support

• compliant electrical connections

Installation suitability should be checked before installation.

Left Handed Connections

Vulcan lists the standard 315L electric water heater with left handed connections.

This can be important for like-for-like replacement installations because existing pipework location may affect:

• installation time

• required parts

• pipework alterations

• installation complexity

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

Water Pressure Requirements

The Vulcan 315L lists:

• ECV setting of 850 kPa

• maximum water supply pressure of 680 kPa with ECV

• maximum water supply pressure of 800 kPa without ECV

• relief valve setting of 1000 kPa

Pressure control valves may be required depending on incoming water pressure and plumbing conditions.

Valve suitability should be checked before installation.

Large System Replacement Considerations

The Vulcan 315L is a large electric storage unit. Its size and weight mean access should be checked carefully before ordering or installation.

This may include:

• stairs

• narrow side access

• steep blocks

• raised platforms

• cupboard locations

• tight laundry spaces

• difficult delivery paths

Additional labour or equipment may be required depending on access conditions.

Vulcan 315L vs Duomax 315L

This page is for the standard Vulcan 315L electric water heater range, not the Duomax listing.

While both systems may appear similar in capacity and application, product codes, availability and installation configurations should be checked carefully before ordering.

Vulcan 315L vs 250L Electric Storage

The Vulcan 315L offers more stored hot water capacity than a 250L electric storage system.

A 250L system may suit:

• smaller families

• moderate hot water demand

• smaller installation spaces

The 315L model may better suit:

• larger households

• higher shower usage

• multiple occupants

• homes regularly exhausting stored hot water

Vulcan 315L vs 400L Electric Storage

The Vulcan 315L is smaller than a 400L electric storage system but still provides strong stored hot water capacity for many larger homes.

A 400L system may better suit:

• very high-demand households

• large homes

• multiple bathrooms

• properties with heavy bath usage

• homes needing maximum stored electric hot water capacity

The 315L model may suit homes wanting large capacity without the additional size and weight of a 400L system.

Vulcan 315L vs Heat Pump Hot Water

The Vulcan 315L uses an electric element to heat stored water directly.

A heat pump hot water system instead uses heat from surrounding air to generate hot water more efficiently under suitable conditions.

The Vulcan 315L may suit customers wanting:

• a straightforward large electric storage replacement

• off-peak electric hot water compatibility

• lower upfront system complexity

A heat pump may suit customers wanting:

• lower electricity consumption potential

• solar PV integration

• energy-efficient hot water upgrades

Vulcan 315L vs Instant Electric Hot Water

The Vulcan 315L stores a large volume of hot water, while an instant electric system heats water as it flows through the unit.

A 315L storage system may suit whole-home family hot water demand more effectively than many instant electric systems.

Instant electric systems may suit specific point-of-use applications but often require significantly higher electrical capacity.

• Investment properties
