The Sabalan geothermal area in northwest of Iran is potentially an important place for tourism in Iran. After realizing the plans for building the first geothermal electric power plant in this region and developing swimming pools, using the geothermal water available in this area, hopefully it will be more attractive for tourists and also provide good sanitation facilities for the local people. According to calculations described in the paper, Gheynarjeh hot spring has been found to be suitable as a heat source for a swimming pool, both with regard to the required temperature and flow rate. The paper also describes the design of a district heating system for Moeil village. The heat load for one sample building was calculated. Comparison of mass flow for a geothermal and fuel-fired system was done, and the influence of radiator size on indoor temperature was analyzed based on a steady-state model. In addition to this, a district heating network was designed and calculations done for it. The simulation results are reasonable and provide a good starting point for a real project.
