ARISTON ANDRIS RS 15/3 EU 15 l 1.2 kW electric water heater, over-sink installation, 3100334

ARISTON ANDRIS RS 15/3 EU, product code 3100334, is a compact electric storage water heater with a 15 L capacity and 1.2 kW rated power, designed for installation above a sink. It is suitable for kitchens, bathrooms, offices and other locations where a compact local hot-water supply is required. For this specific model, ARISTON specifies 220–240 V supply, energy efficiency class A and XXS load profile.
The ANDRIS RS range incorporates TitanShield technology, with a titanium-enamelled inner tank designed to provide durable protection against corrosion. The unit also uses a copper heating element, selected for durability and long service life. ARISTON highlights the careful selection of materials as one of the key factors behind the durability of the ANDRIS range.
Water temperature is controlled by an external mechanical regulator, allowing straightforward adjustment to the required setting. An immersed thermostat provides accurate water-temperature control. A large inspection flange gives easier access to internal components during servicing and maintenance.
A thick layer of high-density polyurethane thermal insulation between the inner tank and outer casing helps retain stored water temperature and reduce heat losses. The model is fully manufactured in Italy and features ARISTON's compact Italian design.
The specific ANDRIS RS 15/3 EU 3100334 has a 15 L capacity, 1.2 kW rated power, 220–240 V supply, maximum operating temperature of 78 °C and maximum working pressure of 8 bar. Heating time at ΔT = 45 °C is 45 minutes, heat loss at 65 °C is 0.61 kWh/24 h, protection rating is IPX1, and weight is 7.4 kg. Overall dimensions A × B × C × D are 360 × 324 × 144 × 78 mm.
The official EU product fiche specifies energy efficiency class A, XXS load profile, water-heating energy efficiency of 35%, annual electricity consumption of 522 kWh, reference thermostat setting of 55 °C and indoor sound power level of 15 dB. EPREL registration number is 108809.
