摘要

A liquid heating appliance (2) for providing heated liquid on demand comprising: a flow heater (4) having an entrance (4a) and an exit (4b) a liquid reservoir (6) having a maximum liquid fill level (14); a pump (8) for conveying liquid from the reservoir (6) through the flow heater (4); and an outlet for dispensing heated liquid from the exit (4b) of the flow heater (4). The liquid heating appliance (2) further comprises a bi-directional flow path from the liquid reservoir (6) to the outlet, the bi-directional flow path passing through the pump (8) and the flow heater (4). At least the entrance (4a) of the flow heater (4) is higher than the maximum liquid fill (14) level of the reservoir (6).
