  • the hot water of the circuit closed 36 which leaves the heat exchange device 37 is sent to the spray nozzle 12 and is typically found at a temperature about 15.5 ° C. This cooled water is sufficient to cool the gases hot which rise through the lining 13, this allowing the water heater 10 double section to obtain an efficiency of about 95% using a single burner or multiple burners 17.
