<p>A device comprises a boiler for containing and heating a liquid; and a cool liquid system that is in liquid communication with the boiler, and that is intended to contain relatively cold liquid. During operation of the device, the boiler is activated such as to heat a quantity of liquid that is received from the cool liquid system. In order to avoid heating up of the liquid that is present inside the cool liquid system and cooling down of the liquid that is present inside the boiler, measures are taken in order to prevent a backflow of the liquid. These measures involve an application of some kind of component (9) to be positioned upstream of the boiler, and in order to avoid heat transfer through this component (9), additional measures are taken to realize a heat insulating effect at a position upstream of the boiler.</p> |
