The heating system is designed according to the calculations based on the 10-year past climate data of the investment area and the climatic data intervals requested by the plant. Apart from the hot water heating system, air heating systems are also used depending on the area and the size of the investment. Installation is provided according to the installation design with pressure-tested hot water heating pipes. In very cold areas, the heating climate in the greenhouse is made effective by increasing the piping quantity in the tunnel area.
