Generated explanation

A building cross section shows a boiler and hot-water distribution piping serving three upper-level radiators and one basement radiator. Red and blue pipe runs and directional arrows indicate circulation through the system. Dashed circles highlight connections between steel and copper piping, where the annotation warns that galvanic action can accelerate rusting. Lower distribution pipes run in contact with the concrete floor, illustrating another location prone to rusting when damp.
