Its compact dimensions make it suitable for kitchens, bathrooms, offices, utility rooms and other applications where a small local supply of hot water is required. For this specific model ARISTON specifies 220–240 V supply, maximum working pressure of 8 bar and energy efficiency class A.

The ANDRIS RS range has a straightforward and reliable design. Water temperature is regulated through a mechanical thermostat, while the immersed thermostat provides accurate control of the stored water temperature. The external adjustment control allows the user to select the temperature best suited to the application.

The model uses a copper heating element with good corrosion resistance. ARISTON also states that the copper heating element helps maintain the hygiene and purity of the heated water. The housing is designed for resistance to water splashes, while the electrical protection rating is IPX1.
