FUEL EFFICIENT RAPID RESPONSE WATER HEATING MODULE A water heating module. The module is adapted for heating water for general residential and commercial use and as a supply for a hydronic heating system. The module is capable of supplying a large volume of hot water near instantaneously on demand without exhaustion. There is a small hot water tank in the module, to supply small demands and to reduce ambient losses while module is in standby. Condensing combustion gases are used to preheat incoming cold water; both features combining to produce high fuel efficiency in the module. A radiant infrared burner may be used in the module to eliminate combustion roar and also to substantially reduce NOx emissions, thus enabling sale of the module in jurisdictions having strict NOx emission standards.
