Improvements in the central heating installations, especially characterized by the use of a single line of pipe for the conduction of the water at the boiler outlet and for the return of the same to the original heater, comprising intercalated in the conduit some sleeves of special joints in T, endowed with a remarkable diametral contraction in its interior that causes overpressures and/or depressions respectively before and after the aforementioned diametral decrease in pitch, which contribute to the effectiveness of the circulatory movements pertinent and inherent to the good running of the heating cycle.
