An instantaneous water heater 2 comprises a heater tank for heating water flowing through the tank, and a diverter valve 8 downstream of the heater tank for selectively directing water from the heater tank to at least one outlet. In a further aspect, a control unit for an electric shower is disclosed, where the control unit has an inlet for connection to a water supply and at least two outlets for connection to respective spray fittings. The diverter valve may be configured to maintain water flow substantially constant when the diverter valve is operated to switch between the spray fittings, such that the outlet water temperature is unaffected. One of the outlets may be connected to a handset 4 via a flexible hose 24 and the other outlet may be connected to a showerhead 6 via a supply pipe 26. The handset may be magnetically located in a parked position on a casing 16 of the water heater. In a preferred embodiment, an electric shower has an instantaneous electric water heater with a diverter valve arranged to direct water from a heater tank to a selected one of two spray fittings.
