It depends on the type of boiler- the most common is a fire tube boiler- hot gases from fire inside the tube and water outside the tube. The tube material is assumed to be at the same temperature and the water is colder- so the heat transfer is calculated over the exterior of the tubes. The heat surface is calculated by multiplying outside Diameter x 3.14 (pi) x length x number of tubes

the calculation goes like this, diam x pi x length of tube in inches x number of tubes divided by 144
so question,, what is the heating surface area of a boiler with 21 tubes, 2.5" in diam, 16' long.
the calculation will look like this.
diam x pi x (16' x 12") x 21 divided by 144
2.5 x 3.1416 x 192 x 21 divided by 144
2.5 x 3.1416 x 192 x 21 = 31667.328
31667.328 divided by 144 = 219.91
