The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat loss in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney) at a lower temperature, allowing simplified design of the conveyance system and the flue gas stack.

Aug 13, 2018 · In these applications, condensing boilers do not use indoor air for combustion and require a means to vent the boiler directly to the outside (not chimney venting). In homes where it may be impractical to vent a boiler directly to outside air without using a chimney, a conventional cast iron gas boiler may be a more viable option.
