Abrégé

A fluid heater comprises an enclosed combustion chamber, at least one burner operatively coupled to the enclosed combustion chamber and a heat transfer section. The heat transfer section has a first end operatively coupled to the enclosed combustion chamber, a second end, an outer wall defining a closed chamber therein, a fluid inlet port coupled to the outer wall in fluid communication with the chamber and a fluid outlet port coupled to the outer wall in fluid communication with the chamber. A plurality of tubes have an opened first end, an opposite opened second end and a chamber extending therebetween, wherein the plurality of tubes are mounted within the heat transfer section so that an outside wall of each of the plurality of tubes and an inside wall of the heat transfer section define the closed chamber. Each of the tube chambers are in fluid communication with the enclosed combustion chamber. A negative pressure source is operatively coupled to the heat transfer section second end and is in fluid communication with each of the plurality of tube chambers, where a continuous flow of hot fluid is produced at the heat transfer section fluid outlet port.

Classes IPC  ?

• F24H 1/12 - Chauffe-eau instantanés, c.-à-d. dans lesquels il n'y a production de chaleur que lorsque l'eau s'écoule, p. ex. avec contact direct de l'eau avec l'agent chauffant dans lesquels l'eau est maintenue séparée de l'agent chauffant
