• additional features - the presence of water purification functions, additional filters, protective valves, etc.;
• modern features - the number of modes, the ease of setting them up, the presence of intelligent modes or, at least, the "ECO" and "Night" modes, clear indication, the possibility of remote control, connection to common smart home systems, etc.
