Its 15-litre storage capacity provides a dedicated supply of stored hot water without requiring a large central hot-water cylinder.

3kW Heating Element and 18-Minute Heating Time

The Andris Lux 15L 3kW uses a 3kW heating element and has a stated heating time of approximately 18 minutes under the manufacturer’s specified conditions.

The 3kW configuration is useful for applications where faster heating and recovery are important compared with lower-powered versions.

Actual heating performance can vary according to incoming water temperature, temperature setting and installation conditions.

Titanium-Enamelled Tank

The Andris Lux incorporates a titanium-enamelled storage tank designed for durability in domestic hot-water applications.

The product also uses a copper, nickel-free heating element and includes an anode for protection of the storage tank.

Adjustable Temperature Control

The Ariston Andris Lux uses a straightforward mechanical temperature-control dial.

An “E” setting is incorporated into the control to help optimise comfort and energy use according to Ariston’s product information.

A heating indicator lamp also shows when the heating cycle is operating.

Where Can the Ariston Andris Lux 15L Be Used?

The 15L oversink configuration can be considered for suitable point-of-use hot-water applications such as:

• Kitchen sinks
• Utility rooms
• Bathrooms
• Washbasins
• Offices
• Small commercial areas
• Workshops
• Guest accommodation
• Remote hot-water points
• Other suitable installations requiring compact stored hot water

The appropriate capacity depends on the expected hot-water demand and the installation requirements.

Ariston Andris Lux 15L 3kW Specifications

The dimensions, weight, heating time, energy class and product code are based on Ariston’s current technical information for the 15 OR 3kW configuration.

Oversink vs Undersink

The Ariston Andris Lux 15L 3kW is available in both oversink and undersink configurations.

The oversink model is designed for installation above the sink, while the corresponding undersink configuration is designed for installation below the sink.

Choose the installation orientation based on available space, plumbing arrangement and the requirements of the installation.

Ariston’s current UK documentation lists the 15L 3kW oversink model as 3100308 and the 15L 3kW undersink model as 3100309.

Andris Lux 15L 3kW vs 15L 2kW

Both models have a 15-litre storage capacity, but the 3kW version has a higher-rated heating element.

Ariston’s technical table lists an 18-minute heating time for the 15L 3kW configuration and 26 minutes for the 15L 2kW configuration.

Is the Andris Lux 15L an Instantaneous Water Heater?

No.

The Ariston Andris Lux 15L is a storage water heater. It contains a 15-litre tank in which water is heated and stored for use.

This distinction is important when selecting a water heater because a storage heater operates differently from an instantaneous or continuous-flow water heater.

Installation Requirements

The Andris Lux 15L is an unvented water heater, so installation must comply with the applicable plumbing, electrical and safety requirements in the destination country.

Before installation, confirm:

• Available installation space
• Electrical supply requirements
• Cold-water pressure
• Hot and cold-water connections
• Required safety components
• Local plumbing regulations
• Local electrical regulations
• Whether additional installation accessories are required

Ariston’s documentation states a maximum designed cold-water inlet pressure of 3.5 bar for the Andris unit and provides installation-kit guidance for applicable configurations.

Installation should be performed by an appropriately qualified professional.
