In the modern world, traditional energy sources are being actively replaced by renewable ones. The most popular is solar radiation, which is increasingly used for heating buildings (heating and hot water supply) [1].

Based on the assessment of the available amount of insolation for the Ivanovo region, a thermal calculation of solar heating systems was performed. To cover the heating load calculated by the balance method, it turned out that the use of solar energy for heating a standard private residential building is technically unfeasible, because the required collector area exceeds the roof area [2].

Figure 1 - Dependence of the collector area on the total solar radiation flux density at 57 вN. to meet the needs of hot water supply.

Analysis of the graph (Fig. 1) shows that in the winter months, solar energy cannot provide the required number of seasonal water heating installations, operating from March to September. thermal power for the needs of hot water supply. However, for these purposes you can use

In the climatic conditions of the Ivanovo region, solar heat supply installations do not fully satisfy the demand for heat energy of individual residential buildings of a standard layout.
