Abstract
The invention relates to a liquid heating device, in particular for household application, mainly for preparing hot beverages comprising a body provided with a liquid flow channel which comprises a liquid inlet and outlet and is connected to at least one electrical heating body whose feeding is controlled by switching means connected to control means. The inventive device is characterized in that the channel consists of at least one first and second portions thereof which are connected to each other by a third channel portion forming a connection conduit, each first and second channel portion are associated with the heating body and the connection conduit is associated with an intermediate temperature sensor connected to said control means, wherein the temperature sensor is disposed in such a way that it is brought into contact with the liquid flowing in the channel and the control and switching means are configured in such a way that it is possible to control the heating body of said at least second channel portion according to the quantity of useful energy supplyable thereto in order to raise the intermediate temperature measured by the intermediate temperature sensor to a specif…
