This paper presents the design of air-heaters made of bimetallic thermosyphons to recover the energy contained in the flue gases of industrial boilers. A computer program written in Visual Basic that performs the thermal calculation of different compact air-heaters was used. With the program it was possible to obtain several configurations of air-heaters that satisfy the operating conditions of a Cleaver-Brooks CB 250 boiler. A compact air-heater was designed with dimensions of only the fifth part of the boiler dimension. With this design efficiency increase of 5% was obtained.
