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. The sensing region is not directly connected to the diffuser portion and is at least partly surrounded by a wall. The sensing region may be provided with a second separate diffuser portion comprising a disc of aluminum brazed to the underside of the base plate.
F24C 1/00 - Stoves or ranges in which the fuel or energy supply is not restricted to solid fuel or to a type covered by a single one of groups Stoves or ranges in which the type of fuel or energy supply is not specified
A liquid heating vessel comprising heating means for heating liquid in the vessel, electronic control means, electromagnetic switching means for interrupting or reducing power to the heating means, and temperature sensing means for providing a signal dependent on the temperature of liquid in the vessel to the control means. The control means is arranged to operate the electromagnetic switching means to interrupt or reduce power to the heating means in response to the control means determining that a pre-determined temperature condition has been reached.
A water treatment cartridge (2) comprises an additive channel (60) arranged so that only some of the water passing through the cartridge (2) passes through it. The additive channel (60) comprises means (72) for automatically releasing an additive into the water in the channel. The additive channel is arranged to control the additive dose. The cartridge may also contain a water treatment or filter medium.
A water treatment cartridge has a major and a minor axis in a horizontal cross-section and mounting lugs provided at the upper end of the cartridge, generally aligned with the major axis of the cartridge.
