Instantaneous handwash taps can provide hot water on demand in virtually any location that has access to water and electricity. It is important to remember (as with all instantaneous electric water heaters) that the power (kW rating) and flow rate are the key parameters that determine outlet water temperature. Products in this category are of relatively low power a only suitable for light duty applications such as hand washing in cloakrooms. If the water is too cold decrease the flow, if it is too hot then increase the flow. Always choose the kW rating carefully and ensure that the temperature rise and flow rate are acceptable for your application.
