Nowadays, energy is the primary input for all economic activities. It plays a significant role in raising the standard of living, which has become the ultimate goal of most communities. This natural energy can be produced from the earth's heat, used for heating, and cooling buildings, generating electricity, and providing warm/cold water for agricultural items in greenhouses. Jordan's NE and SE deserts have geothermal resources. Based on that, the researcher developed a project that uses hot water from the Shaydia mine to heat the buildings. Talking about If geothermal power is used, then the cost of the heat exchanger should be saved. Thermal loads and mass flow rates were calculated manually to determine the size of the system. The cost of the project has been calculated by ordering all parts and pipelines from many companies, comparing their prices, and testing with their average prices. This paper shows how to control mass flow rate for all apartments by varying convection heat transfer coefficient with outdoor and indoor temperatures. The heat load is 3828 kW, so 82.08 m3/h of flow is needed to cover all residential structures and 0.33 L/h of chemical treatment before water enters the network. After calculating the costs of the current system and comparing them to the costs of the project to see if it is possible or not, it's found that it is possible and very available to the company, which will bring in about $300,000 per year.
