An important priority of Ukraine's economic policy is careful use of energy resources. The country has a broad-based energy efficiency policy, and energy efficiency is complex, covering both the legislative framework and technical innovations. One of the effective ways to reduce energy costs for the needs of the national economy is to carry out thermal modernization of the heating system. In this article economic indicators of thermal sanitary measures during reconstruction of the heating system of the object are given. In the reconstruction of the heating system, the following thermal renewal measures were adopted for comparison: the installation of the air solar collectors, the reconstruction of the heating system, and the installation of air solar heating system.
