Compact high volume point of use instantaneous water heating system

摘要

A point of use, instantaneous, high-volume water heating system includes a compact accumulator tank fed by one or more instantaneous gas-fired auxiliary water heaters operating asynchronously to provide a supply of hot water on demand heated to a predetermined temperature. The accumulator tank includes a baffle which separates water in the tank into two temperature zones. A thermostat within the accumulator controls a pump which feeds water from a conventional water heater to the auxiliary water heaters, or alternatively recycles tank water to the auxiliary heaters, when the temperature in the accumulator tank drops below a predetermined minimum.
