It how-ever can be connected with equallysatisfactory results at the top con-nection of the boiler, as shown bythe dotted line. At the highestpoint an air cock is fitted to relievethe loop of air collecting there. Ifthe system is supplied from anoverhead tank this air cock canbe replaced by a pipe whicliis taken to a point higher than the tank and then returned to apoint over it so that any water expanded back through it will bedelivered into the tank. No air cock is required on the coil asthe cock or air pipe on the high point relieves the coil of airalso. The return pipe is connected to the return connection ofthe water front as shown and a stop cock on this pipe also ef-fectively prevents water backing up into the coil at such timesas its use is not Fig. 108. Coil on Floor Above Boiler Heated from Water Back. Connecting Coils on Floor Above Range. The circulation of water to a coil or radiator on the floorabove the boiler is a simple matter. Two methods of connectingthem are here shown. In Fig. 108 the circulation between the UTILIZING EXCESS HEAT. 145 back and boiler is fully maintained and is direct, while the cir-culation between the boiler and heating coil or radiator is alsosecured, the descending or cooler column—that is, the returnwater from the heating coil—being arranged to flow in the samedirection as the same column from the boiler to the back. InFig. 109 the flowpipe, or ascend-ing column, istaken directlyfrom the waterback to the heat-ing coil, on thehorizontal partof which pipeis a circulatingpipe, to thebo
