Indirect radiation embraces all heating snrfaces placed outside the rooms to be heated, and can only be used in connectionwith some system of ventilation. For warming by direct radiation, the radiators usually consist of coils, composed of f-inch and 1-inch steam pipes, whichare arranged in parallel lines and are coupled to branch tees orheads. In a few exceptional cases, radiators of peculiar shapesare specially constructed. In all cases the coils must haveeither vertical or horizontal elbows of moderate length, forallowing each pipe to expand separately and freely. Sometimesshort lengths of pipe are coupled by return-bends, doublingbackwards and forwards in Be\eral replications one aboveanother, and forming what are
