Ariston Pro1 Eco S 100L 3kW Electric Storage Water Heater with Unvented Kit

Ariston Pro1 Eco S 100L 3kW. The largest model in the range for installations where more stored hot water is a priority. This wall-mounted electric storage heater offers a practical alternative to a conventional hot water cylinder where the available space and demand suit a compact vertical unit.

A robust approach to everyday hot water

ECO EVO learns usage patterns to help plan heating around your routine. The electronic thermostat provides temperature control, while the enamelled tank and magnesium anode support corrosion protection. These features make the range worth considering for domestic and light commercial hot water projects.

• 100L model size with 95 litres stated tank capacity.
• 3kW electric heating and vertical wall mounting.
• ErP B energy rating.
• Unvented installation kit supplied.
• Tank warranty up to 5 years; electrical components up to 2 years, subject to terms.

Choosing the 100L model

Size the heater around peak demand and the time available for reheating, rather than capacity alone. A kitchen, washroom or small premises may have very different usage patterns from a home. The stored capacity should not be treated as a promise of unlimited hot water.

Before ordering, have your installer confirm wall strength for the filled unit, service access, the electrical circuit and the unvented discharge arrangement. The supplied kit forms part of the installation; additional pipework and site-specific fittings may still be required.
