A flow-through liquid heating apparatus comprising:
a. a heated flow path (28) arranged to heat liquid flowing therethrough
b. and depressurising means (22) downstream of the heated flow path (28) for causing a pressure difference between liquid flowing through the heated flow path (28) and liquid leaving the depressurising means (22), such that the liquid leaves the depressurising means (22) at or above boiling point, but is substantially prevented from boiling within the heated flow path (28).
