A liquid heating appliance comprising: a liquid reservoir comprising at first chamber arranged below a second chamber and separated by a partition extending therebetween, a heating arrangement arranged to heat, in use, liquid contained within the first chamber; a liquid outlet in the first chamber in fluid communication with a dispense outlet provided on the appliance so as to allow liquid to be dispensed from the first chamber; and characterised in that the heating appliance further comprises: a first valve, a second valve and a float valve disposed in the partition to selectively allow liquid to flow between the first and second chambers, wherein said first and second valves are arranged such that respective lines (57a, 57c) joining the first and second valves to a centre of the partition have an obtuse angular separation and wherein the float valve comprises a floating valve member arranged to float and mate with a valve seat and thereby close the valve in order to prevent the flow of liquid through the valve; and at least one valve closure member arranged selectively to close said first and second valves; and wherein the liquid outlet is in fluid communication with the dispense outlet so as to allow liquid to be dispensed from the first chamber when the first and second valves are closed. a liquid reservoir comprising at first chamber arranged below a second chamber and separated by a partition extending therebetween, a heating arrangement arranged to heat, in use, liquid contained within the first chamber; a liquid outlet in the first chamber in fluid communication with a dispense outlet provided on the appliance so as to allow liquid to be dispensed from the first chamber; and characterised in that the heating appliance further comprises: a first valve, a second valve and a float valve disposed in the partition to selectively allow liquid to flow between the first and second chambers, wherein said first and second valves are arranged such that respective lines (57a, 57c) joining the first and second valves to a centre of the partition have an obtuse angular separation and wherein the float valve comprises a floating valve member arranged to float and mate with a valve seat and thereby close the valve in order to prevent the flow of liquid through the valve; and at least one valve closure member arranged selectively to close said first and second valves; and wherein the liquid outlet is in fluid communication with the dispense outlet so as to allow liquid to be dispensed from the first chamber when the first and second valves are closed. a first valve, a second valve and a float valve disposed in the partition to selectively allow liquid to flow between the first and second chambers, wherein said first and second valves are arranged such that respective lines (57a, 57c) joining the first and second valves to a centre of the partition have an obtuse angular separation and wherein the float valve comprises a floating valve member arranged to float and mate with a valve seat and thereby close the valve in order to prevent the flow of liquid through the valve; and at least one valve closure member arranged selectively to close said first and second valves; and wherein the liquid outlet is in fluid communication with the dispense outlet so as to allow liquid to be dispensed from the first chamber when the first and second valves are closed.
