Abstract

This research obtained results of the evaluation of the thermal performance of three reservoirs used for heating of water with solar energy. Being a cylindrical metal one, a spherical in thermofix compound with fiberglass and a cylindrical in compound fixed term with fiberglass. Nowadays the job of cylindrical reservoirs is the constant one due to the easiness of execution, however this cylinder isn’t the most efficient anymore, which is shown in this study. Once defined that the most appropriate shape was the spherical one, were started series of tests aiming at the practical proof in service and the viability of his use in low costs residences. The work done permitted to identify and to affirm that spherical reservoirs are most indicated one for this aim, presenting less loss of heat and consequently reduction in the operational and manufacturing costs allied to less quantity of raw material.
