In this regard, it is appropriate to turn your eyes to those countries where the problem of loss of thermal energy is solved most successfully and the operation of the ITP is facilitated. Germany is the best example. This country takes the most stringent measures to maintain energy already at the stage of installation of pipelines. They are made using the most modern technologies that provide almost perfect thermal insulation, as well as guaranteeing the preservation of thermal energy by thermal insulation of the walls of residential and administrative buildings. The size of our country, sloppiness at all levels, greatly complicates the 100 % use of German experience in full. But the most important thing is that we have the process of preservation, the savings of heat, as they say, has gone. Today, the increasing amount of the built -up and overhaul housing provides for the laying of the thermal insulation layer. Such work on a Russian scale is really a very important, one might say, political task.
