2. Description of appliance
This instantaneous water heater is intended to provide the economical heating of water suffi-
cient for a single outlet, i.e. handwash basin, and must be connected to a special open-outlet
tap to avoid any overpressure. Appliances with a higher power rating can also be used to
supply a kitchen sink. They will also provide a basic shower when used with a special shower
fitting.
When the hot water tap is opened, the instantaneous water heater switches itself on auto-
matically and heats the water as it passes through the appliance. It is only then that the appli-
ance uses electricity. The temperature increase depends on the flow rate.
