Smarter Heating, More Hot Water, Less Waste

The Ariston Velis Pro 80L 1.5kW White Unvented Electric Water Heater is a premium, wall-mounted electric water heater designed for compact spaces and energy-efficient performance. The Ariston Velis Pro uses a clever double tank design that heats water faster and keeps it hotter for longer. It also stops cold water from mixing too much with the hot, so you get more usable hot water when you need it.

And with the ECO EVO smart function, the heater actually learns your daily routine in just 15 days. It remembers when you usually need hot water and heats just the right amount — saving energy and cutting down on waste. That means lower bills and hot water always ready when you need it.
