17,237. J÷rgensen, H. V. Aug. 5. Heating buildings &c.-Relates to a method of increasing the circulation in hot-water plant by cooling the water in or near the top of the main rising tube. In the arrangement shown in Fig. 1, the cooled return water is conducted by the pipe 6 to the pipe 9, which is connected with the con- densing-device 10 surrounding the expansion chamber 3. The boiler 1 is connected with the device 10 by the pipe 11, and also with the pipe 6 through a reduction valve. In the system shown in Fig. 2, the cooling is direct, as the main tube 2 is provided with the branch pipe 12 leading to the expansion chamber 13 in the tube 9. The pipe 12 ends in a tapered mouthpiece. In a further modi- fication, the return water is conducted before passing to the boiler to a chamber through which part of the heated water passes in a spiral tube and is cooled. Steam bubbles pass from the boiler 1 with the hot water.
