The compact stainless-steel tank is not under mains pressure, so the system is unvented and therefore no excess water is discharged to drain. The inner tank has several electrical safety features. A temperature sensor to give an accurate digital external reading of the current water temperature. A float sensor detecting the water level in the tank, this avoids dry start that would damage the boiler. An overheat stat to ensure the unit never overcooks.
