An induction heating device for heating a liquid comprises a half ellipsoidal shaped induction coil 22 and matching susceptor 30. The coil and susceptor may be formed with the liquid heating vessel 24 and the susceptor may be spaced from the inside of the vessel to allow liquid circulation (fig 2 not shown). Alternatively as shown in fig 4 the coil 222 may be external to the vessel 220 with the susceptor 230 integral with the vessel. A load cell 250 with a vessel engaging projection 248 along with an infrared temperature sensor 256 and a calibrating button 252 are provided to send signals to the controller 258. The base 212 may be illuminated to indicate operation and may also function as a night light when the unit is not being used for heating a babyâ s milk/formula. The vessel is adapted to be attached to a feeding bottle. A light sensor/infrared transceiver 262 may detect markings applied to the vessel whereby rotation of the vessel sets target temperature, heating time etc. The arrangement may also be applied to induction hobs, fryers, urns, wax melt pots, freeze protection systems and immersion heaters
