Determination of boiler capacity 46 (1) In this section, "extended surface" does not include the area of a superheater. (2) The heat receiving surface area of a boiler must be stated in square metres (m2), must include the extended surface and the heating surface must be computed as follows: (a) a heating surface, as part of a circulating

Boiler Surface Area: More is not Necessarily Bett

The conclusion is: Simply deciding on a particular boiler design or supplier simply because the design has more surface area can be wrong. Unless one can perform heat transfer calculations and check the surface area of each boiler, one should stay away from comparing surface areas.
