The objective of this study is to develop a winter heating system for the mechanical engineering faculty rooms at the Madhav Institute of Technology and Science in Gwalior, India. The solar energy systems are auxiliary power in addition to electric power because of the severe lack of electric power, particularly the energy used for heating and cooling during government and private sector offices’ official working hours. This is why our designed solar space heating system only uses solar power during those hours. The method used in this study is intended to heat faculty rooms for eight hours at a time. During the winter of November–December 2022.The design calculations for the necessary space heating load were the first step in the investigation, and this amount 1098 W/day has been determined. The energy supplied by solar collectors with evacuated tubes that are appropriate for the necessary heating demand and its value 23,166 kJ/day. A data logger, a measuring and recording device, and a solar metre to save data on solar radiation rate were used to take the readings every 60 min, respectively. The analysis demonstrated how the system compensates 6.4 kWh/day for the electricity used to heat the rooms 18 m2 size.
