A steam generating appliance such as an electric iron comprises a base unit (91) and a hand-held mobile unit (1) which can be releasably coupled to the base unit. The base unit comprises a reservoir for water and a pump for pumping water from the reservoir into the mobile unit when the mobile unit is coupled to the base unit. The mobile unit comprises a boiler (52) and an on-board reservoir for water (36), wherein the on-board reservoir (36) is adapted to store water received from the base unit (91) under pressure and to deliver the water to the boiler (52) under the control of a user-operable valve (46).

An apparatus for heating liquid comprises a heating chamber (704), a dispensing chamber (712) and a conduit (710). The conduit (710) conveys heated liquid from the heating chamber (704) to the dispensing chamber (712) for automatic dispensing. The dispensing chamber (712) has valve means (714) through which the heated liquid is dispensed, which are operable to interrupt the automatic dispensing. An apparatus for heating liquid comprises a heating chamber (804), a dispensing chamber (812) and a conduit (810). The conduit (810) conveys heated liquid from the heating chamber (804) to the dispensing chamber (812) for automatic dispensing. The apparatus comprises means (866) for determining a volume of heated liquid to be dispensed automatically.
An electric infusion beverage maker (2) comprises a liquid heating chamber (4) having electric heating means (12) associated therewith for heating liquid in the chamber (4), An infusion chamber (6) receives in use a beverage to be infused. A pump (30) transfers heated liquid from the liquid heating chamber (4) to the infusion chamber (6) at a transfer rate. The infusion chamber (6) has outlet means (38) arranged such that beverage-infused liquid drains out of the infusion chamber (6) and into the liquid heating chamber (4) at a drainage rate which is lower than the transfer rate. This means that liquid cannot pass straight through the infusion chamber (6).
A liquid heating apparatus has a first mode of operation in which a first volume of water can be heated and a second mode of operation in which a second, smaller volume of water can be heated and automatically dispensed. The first mode may be provided by a removable liquid heating vessel (40). The second mode may be provided by a second heating chamber (58) comprising a heater (76) arranged to heat liquid and dispense it through an outlet (45). The second heating chamber (58) is filled with water from the removable liquid heating vessel (40).
An apparatus for heating a measured amount of water comprises a heating (chamber 8), a dispensing chamber (10) and a conduit for conveying water from the heating chamber to an inlet of the dispensing chamber (14). The apparatus is arranged such that an increase in pressure associated with boiling forces heated water into the conduit 14 and then into the dispensing chamber (10).
An underfloor heater for a liquid heating vessel comprises a base plate, a heat diffuser portion in good thermal contact with the base plate, a heating element in good thermal contact with the diffuser portion and a sensing region for receiving a thermal sensor.
