Quick Specifications

Vitreous Enamel Lined Cylinder

The Vulcan 50L uses a vitreous enamel lined cylinder designed to help protect the inside of the cylinder from water contact.

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.

Compact 50L Storage Capacity

The 50L capacity makes this Vulcan model suitable for limited hot water demand.

This may suit:

• apartments

• small kitchens

• office amenities

• studios

• granny flats with low demand

• low-use hot water points

It is generally not the best option for:

• larger households

• multiple bathrooms

• heavy laundry demand

• high-volume shower usage

The correct system size still depends on:

• daily usage

• shower duration

• outlet flow rates

• climate conditions

• occupancy

Single 3.6 kW Element

The Vulcan 50L uses a single 3.6 kW electric element designed for continuous tariff connection.

Electrical suitability should be checked before installation.

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

Internal or External Installation

The Vulcan 50L may be installed indoors or outdoors where suitable.

Indoor or cupboard installations may require:

• safe trays

• compliant drainage

• leak protection

• service access

Outdoor installations require:

• suitable weather exposure conditions

• plumbing access

• compliant electrical connections

Installation suitability should be checked before installation.

Dual Handed Connections

The Vulcan 50L includes dual handed connections.

This may make replacement installations easier because the system offers more flexibility than single-sided connection models.

This can be useful when replacing:

• older compact electric water heaters

• cupboard installations

• apartment systems

• kitchen hot water units

where pipework alignment matters.

Continuous Tariff Requirement

The Vulcan 50L electric water heater is listed as requiring connection to continuous tariff.

Small-capacity electric storage systems generally need reliable reheating availability due to the limited stored water volume.

Tariff suitability should be checked before installation, especially if replacing an older hot water unit connected to a different electrical arrangement.

Water Pressure Requirements

The Vulcan 50L 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

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

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

Small Space Replacement Considerations

The Vulcan 50L is designed for compact spaces and low-demand hot water use.

Its smaller dimensions may suit:

• cupboards

• compact laundries

• office kitchens

• apartments

• utility spaces

Before ordering, the installation location should still be checked for:

• height

• width

• depth

• drainage

• service access

• plumbing layout

• electrical access

Tempering Valve and Element Information

*Element size information:
All electric hot water units are supplied as standard with a 3.6kW element unless otherwise stated on the product page, invoice, or order confirmation.

If a different element configuration is requested, such as 1.8kW or 2.4kW, the hot water unit may still arrive with the standard 3.6kW element fitted from the manufacturer. The requested 1.8kW or 2.4kW element will be supplied separately with the order for installation by a suitably licensed electrical contractor or licensed electrical licence holder.

Any element changeover, electrical connection, disconnection, wiring, testing, or modification must be carried out by a licensed electrical contractor or licensed electrical licence holder. Elements must not be changed, connected, modified, or tested by an unlicensed person.

Alternative elements supplied for non-standard configurations may be generic replacement elements and may not be the same brand as the hot water unit unless specifically stated. Generic elements are supplied to suit the requested element size and electrical configuration, but final suitability must be checked by the licensed installer before installation.

1.8kW and 2.4kW elements supplied separately with a hot water unit include a 12-month supply-only parts warranty from the date of purchase, provided the element has been correctly installed by a licensed electrical contractor or licensed electrical licence holder and used under normal operating conditions.

This element warranty covers the replacement supply of the element only. It does not include labour, call-out fees, electrical work, plumbing work, fault finding, removal, reinstallation, testing, travel, downtime, damage caused by incorrect installation, or any other associated costs. Warranty may be declined where the element has been incorrectly installed, dry-fired, modified, damaged, connected to incorrect voltage or wiring, affected by power issues, used in unsuitable water conditions, or installed by an unlicensed person.

Proof of purchase, installer details, electrical licence details, photos, and/or return of the faulty element may be required before a warranty claim is approved.

**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.
