<p>A water heater vessel comprises an upper reservoir (14) for receiving water, a heating chamber (53) below the reservoir (14) and a dispense mechanism (48) arranged to dispense water automatically from the reservoir (14) into the heating chamber (53) until a predetermined level in the chamber is reached. The vessel may comprise a float valve (50,52) for determining when a predetermined level in the heating chamber (53) has been reached. The vessel can heat only as much water as is required at a time.
