Abstract
At present, there is a tendency to increase the need for efficient heaters that have high operational characteristics. The heater is an effective instrument for reducing heat losses in multi-layered enclosing structures, as well as reducing financial costs for heating the building. Most of the thermal losses are accounted for by the enclosing structures of the walls, so the comparative analysis of popular heaters in construction is a relevant topic. The purpose of the study is the selection of the most effective insulation for multi-layered enclosing structures in the climatic conditions of the city of Kyzylorda based on comparative analysis. In the process of research, it was established by calculation that out of all the majority selected for the calculation of insulation, mineral wool P-75 provides full economic expediency of application as insulation. With the help of the Elcut software complex, the heat losses occurring in the wall structures were calculated.
