Ariston Velis Tech Wi-Fi 45L Slimline Electric Water Heater with Unvented Kit

Ariston Velis Tech Wi-Fi 45L brings a slimmer profile to stored hot water. The 45L model is worth considering where demand is modest and available wall space matters. Its twin-tank layout offers a considered option for projects where the heater will be visible as well as functional.

Comfort with a slimmer footprint

The brushed-metal finish and Ariston NET compatibility give Velis Tech Wi-Fi a distinctive place in the range. App control can help you manage hot water availability, while ECO EVO learns your usage pattern. Its heating system draws a maximum of 3kW at any given time.

• 45 litres actual storage capacity.
• Slimline twin-tank construction.
• ErP B energy rating.
• Vertical installation with the supplied unvented kit.
• Up to 5-year tank warranty, with separate electrical component cover.

Choose capacity and controls around your routine

A shower-ready indication means enough heated water is available for an initial shower under the manufacturer’s test conditions; it does not mean the entire tank has completed its heating cycle. Consider shower flow, back-to-back use and recovery time before choosing the size.

Your installer should check mounting support, service clearance, the circuit and the discharge route. For app features, check current Wi-Fi and phone compatibility and allow for account setup.

Product specifications

Manufacturer warranty

Up to 5 years on the tank and up to 2 years on electrical components, subject to Ariston’s applicable warranty terms, installation and maintenance requirements.
