ARISTON ANDRIS RS 10U/3 EU, product code 3100330, is a compact electric storage water heater with a 10 L capacity and 1.2 kW rated power, designed specifically for installation under a sink. This configuration makes it suitable for installation inside a cabinet beneath a kitchen sink or bathroom basin, providing a local supply of hot water close to the point of use. For this specific model ARISTON specifies a 10 L capacity, 1.2 kW power rating, 220–240 V supply and under-sink installation.

The ANDRIS RS range has a simple and reliable design with mechanical temperature regulation. The unit uses a copper heating element, which provides corrosion resistance and contributes to maintaining good hygiene of the heated water. ARISTON states that products in the ANDRIS range have passed the required safety tests for compliance with CE requirements.

For the ANDRIS RS 10U/3 EU, maximum operating pressure is 8 bar, maximum operating temperature is 78 °C, and electrical protection rating is IPX1. Heating time at ΔT = 45 °C is approximately 30 minutes, while heat loss at 65 °C is 0.71 kWh/24 h. Net weight is 6.6 kg.

The compact housing measures only 360 mm in height and 276 mm in width. ARISTON additionally specifies dimensions c = 144 mm and d = 92 mm, allowing accurate assessment of the space required beneath the sink.

In terms of energy performance, the ANDRIS RS 10U/3 EU has energy efficiency class B with XXS load profile. The official EU product fiche specifies water-heating energy efficiency of 33%, annual electricity consumption of 561 kWh, reference thermostat setting of 45 °C and indoor sound power level of 15 dB.
