Renovation and Upgrade of Domestic Cold and Hot Water Pipelines in the Brothers’ Dormitory Blocks and Implementation of a Hot Water Recirculation System

The Director of Technical Affairs and Development Projects at the University of Kashan announced that, in line with the University’s water and energy management policies, the project to replace the domestic cold and hot water pipelines in Blocks 1, 2, and 3 of the Brothers’ Dormitory, along with the implementation of a domestic hot water recirculation system, has been completed and put into operation.

Dr. Zahra Jamshidzadeh stated that prior to the implementation of the project, the absence of a hot water recirculation system resulted in a considerable amount of water being wasted while waiting for hot water to reach consumption points. In addition, the deterioration of sections of the distribution network had led to increased thermal losses and, consequently, higher energy consumption in the boiler room. She added that the project was carried out to address these issues and to enhance the efficiency of the domestic hot water distribution system.

She further noted that the project included approximately 600 meters of piping operations, replacement and modification of transmission routes, full insulation of pipelines, and the development of necessary infrastructure, including the construction and installation of a collector and the installation of a domestic hot water circulation pump. The project was implemented by the University’s facilities personnel with appropriate planning during periods when students were not present.

Dr. Jamshidzadeh also stated that a domestic water recirculation system had previously been installed in Block 6 of the Sisters’ Dormitory during the summer of 2024. With the completion of the present project, four dormitory blocks at the University of Kashan are now equipped with a domestic hot water recirculation system, and the implementation of this system in other dormitory blocks is currently underway.

The Director of Technical Affairs and Development Projects identified the following as key outcomes of the project:

• An average reduction of 10 to 20 percent in domestic hot water consumption in the dormitory blocks

• An approximate 15 to 25 percent decrease in thermal energy consumption required for water heating

• Increased service life of mechanical equipment due to more stable system performance, reduced thermal shock, and decreased wear and tear on equipment, including boilers, pumps, and valves

• Reduced environmental pollutant emissions as a result of lower energy consumption
