A method for providing an electric instantaneous water heater with an earth bond comprises fitting a conductive device (20,40) to the water inlet pipe (3,30) of the heaters plastic bodied solenoid valve, causing the device (20,40) to make electrical contact with a copper water supply pipe (10) through the action of an olive (9) and nut (8) of a compression joint fitting and provide the device (20,40) with a conductive cable (23,43) for connection to a metallic element associated with the heating element of the heater.
