Early designers of buildings left us, generations later, with few choices for upgrading and/or replacing existing internal heating plants. Little thought was put into the challenges designers and installers would face when the original plant became obsolete. Some buildings have their boiler plants buried so deep in the bowels of a sub-basement, one may need to have physical training just to get there!
So what do we do? Being intuitive, problem solvers (and creators) by nature, we figure out a way to conquer this problem. The pencil hits the pad, and a component boiler is born. “Out-shop” or “field-assembled” boilers allow replacement without requiring the often prohibitive expense of structural modification, excavating, extensive rigging and associated state and local permits. With a field-erect boiler, the integrity of the building is not disturbed at all. The field-erect boiler is a positive alternative.
