Product information

Description

The Ariston VELIS TECH WIFI 100 EU is a high-performance electric water heater designed to provide reliable hot water for modern households. With a generous 100-liter capacity and a slim, space-saving design, this unit offers flexible installation options, allowing it to be mounted either horizontally or vertically to suit your specific interior layout. Equipped with smart Wi-Fi connectivity, it allows for convenient remote management, ensuring that hot water is available exactly when you need it while optimizing energy usage.

Advantages

This water heater stands out due to its advanced energy efficiency, holding a class B rating which helps in reducing annual electricity consumption. The inclusion of an intuitive LCD display provides clear feedback on the current status and temperature settings, making it easy to monitor performance. Its dual-tank architecture ensures faster heating times compared to traditional models, while the robust construction supports a maximum operating pressure of 8 bar, guaranteeing safety and durability for long-term domestic use.

Suitable for

Residential apartments and houses requiring efficient hot water solutions
Spaces where flexible horizontal or vertical wall mounting is necessary
Users who prefer remote control via Wi-Fi for energy management
Modern households looking for a compact, slim-profile water heating appliance

When it may not be suitable

This unit may not be ideal for large commercial facilities or industrial applications that require a significantly higher volume of hot water than a 100-liter tank can provide. Additionally, if your household electrical system cannot support a 1500W load or if the installation area lacks sufficient wall strength to support the weight of a full 100-liter tank, alternative solutions should be considered.
