In the article, the results of the temperature of the autonomous helio-greenhouse of the trench type in the abnormal cold climatic conditions of Uzbekistan are discussed. During the winter heating season at ambient temperatures from -40 °C to -21 °C, experiments were carried out, which showed that at an outdoor air temperature of less than -10 °C there was no need to use emergency heating sources, and the temperature in the autonomous greenhouse dropped to 5 °C. A two-circuit combined system based on an electric boiler and a solar water heating system has been proposed and applied as an emergency heating source. At an ambient temperature of more than -200 °C, the air temperature wizened at
