Find the Right Ariston Electric Water Heater

Choosing a water heater starts with how and where you need hot water. A compact unit serving a kitchen sink has different requirements from a larger storage heater supplying a bathroom. Compare the heater type, capacity, electrical rating and installation requirements before ordering.

Andris: Compact Point-of-Use Water Heaters

Ariston Andris water heaters provide stored hot water close to the point of use. They are worth considering where a sink or basin is some distance from the main hot water supply, or where a local electric water heater is needed.

Check the individual model’s capacity and mounting arrangement carefully. Oversink and undersink versions must be selected for the intended installation. Selected models, including Andris Elite Wi-Fi, also offer connected controls.

Velis: Slimline Electric Storage Water Heaters

For installations needing more stored hot water, explore the Ariston Velis models listed in this collection. Velis Tech Wi-Fi combines a slimline design with twin-tank technology and connected control through the Ariston NET app.

When comparing models, check the stated storage capacity, dimensions, mounting options and hot water performance. Check the product listing to see whether an installation kit is included or needs to be ordered separately.

Aures: Instantaneous Electric Water Heating

Ariston Aures instantaneous water heaters heat water as it passes through the appliance, rather than keeping a tank of hot water in storage. Aures Multi provides an alternative to a storage heater where the available electrical supply and required hot water flow suit the installation.

Before choosing an instantaneous heater, ask your installer to check the electrical requirements, incoming water conditions and expected outlet temperature and flow.

Looking for Ariston Water Heater Spares?

The correct replacement part depends on the exact appliance, not simply the Ariston brand name or the appearance of the component. Model variations and production changes can affect compatibility.

  • Installation accessories: check which valves, controls and other components your installation requires.
  • Product details: check the individual listing for included accessories, warranty information and availability.

Ariston Water Heaters & Spares: Frequently Asked Questions

What is the difference between an Ariston storage and instantaneous water heater?

A storage water heater heats water and holds it in a tank for use later. An instantaneous water heater heats water as it flows through the appliance. The right choice depends on hot water demand, available space, electrical supply and the required flow and temperature.

Do all Ariston water heaters have Wi-Fi?

No. Wi-Fi is available on selected models, including Andris Elite Wi-Fi and Velis Tech Wi-Fi. Check the exact product name and specification before ordering.

How do I identify the correct Ariston water heater spare?

Start with the full model name and product code on the appliance rating label. A clear photograph of the label, the existing component and any part number will help us check compatibility and whether we can source a replacement.

Is an installation kit included with every Ariston water heater?

No. Supplied accessories vary between products and packages. Check the individual listing for what is included and ask your installer to confirm any additional components required for your installation.
