MULTI-CHAMBER WATER HEATER

摘要

A water heater which includes a tank (60) with a water inlet (64) and outlet (26). At least one divider (18) for dividing the tank into a plurality of chambers (12), (14) with adjacent chambers being arterial (28). A first chamber (14) is connected to the outlet and another one of the chambers (12) is connected to the inlet. Heating means (20) may be located in some or all of the chambers. The dividers may be oriented vertically or horizontally (18). They may be movable and of specific construction including apertures (28) therein for arterial connection to adjacent chambers which apertures may contain flow control thermostats. They may be insulated to reduce heat transfer between compartments. Where displacement is via density/temperature changes in a compartment, stops may be provided to limit the travel of the dividers/partitions. Sacrificial protection (74) may be provided for the tank.
