The Ariston Velis EVO 80 litre electric boiler has a very attractive and flat design of just 27,5cm in depth. This electric water heater is very energy-friendly and is classified with a B energy label. It has two, smaller titanium enameled steel tanks. The 80 litres heats up in about 55 minutes shower temperature thanks to two smaller tanks instead of one cylinder. To heat it up to 65 degrees celsius it takes just over 2 hours. The ECO function of this electric water heater makes it a very energy-efficient unit. 

The Ariston Velis EVO electric boiler has two elements. One heating element is 1000 watt and the other has a 1500 watt capacity. The maximum rated power is 1500 watt. So you could actually install it in your caravan without any problem. ABS 2.0 safety system protects the electric water heater from power cuts.

The completely new auto-learning ECO EVO software paired with the electronic, intelligent thermostat manages the water temperature independently. As it records the users habits with regards to timing and water usage. 

We can supply one of two pressure relief valves free of charge. Please indicate, which one you prefer by ticking the box at 'Available options' when ordering. The valve with the red lever has a small orifice. You can connect the supplied discharge pipe that orifice to drain of drops of expansion water. The other valve is a WRAS approved pressure relief valve. This WRAS approved valve can only be used together with a WRAS approved check valve and a WRAS approved expansion vessel.
