Technical Examples
This invention relates to an electric water heater comprising one or more heating resistors and the means for supplying and controlling electric power supplied to the resistors. The heaters of the present invention are capable of heating incoming water to a desired temperature in the time period required for the input water to flow from the heater water inlet to the heater water outlet, thus requiring no storage capacity. Further, high electrical power consumption, normally associated with on demand or instantaneous electric water heaters is reduced by powering only such of the heating elements as may be required to meet demand. In addition, the heaters of the present invention utilize innovative cartridge heating elements which drastically reduce maintenance time and expense by allowing for the removal and replacement of the spent or defective heating elements from the air side of the flange, as opposed to the wet side, thereby eliminating the need for draining or disassembling of the unit during servicing.
