Abstract

A hot water supply system operated by linking plural water heaters. A system controller is provided in every specific number of water heaters for centralizing controls thereof. A host system controller is further provided in every specific number of the system controllers for centralizing controls thereof, and finally the controls are centralized in one highest system controller. In this configuration, therefore, the highest system controller controls the operation of individual water heaters by way of the lower system controllers.
