The summary. Nowadays, in parallel with the development of technology, there is a significant increase in energy consumption. Addiction to fossil fuels is increasing in order to meet the generated consumption. The emission of these resources causes global warming by creating a greenhouse effect. When literature is studied, studies on the use of renewable energy sources, such as wind and solar energy, are often on the forefront. In addition, achieving the maximum output of the energy produced also holds an important place in literature. To ensure the efficient use of energy, waste heat or solar energy, which is a renewable energy source, must only be stored for a certain period of time. Water with high heat capacity for this is widely used as a storage mass. The intensity of the water varies depending on the temperature. So during heating and cooling, the water that changes the temperature is exposed to the transfer flows within the warehouse. Although this situation is seen as beneficial for the heat transition at first glance, the heat recovery from the warehouse occurs at a lower temperature because the temperature gradient is reduced due to the heat transition. This study is aimed at blocking connective flows and absorbing the drawn heat at higher temperatures. For this purpose, water-smoked glass wheat is used as a warehouse equipment. According to the results obtained, the water absorbed glass wheat mass was observed as solid. This has made it possible for the internal energy to be recovered at a higher temperature in the glass wave warehouse equipment compared to the non-glassed warehouse. On the other hand, there was a decrease in the amount of energy stored and the heat transition was slowed. Keywords: Heat transfer, Thermal energy storage, Convection, Thermal layer Abstract. Today, there is a significant increase in energy consumption in parallel with the development of technology. To supply the consumption, dependency on fossil fuels have increased and emissions, which occur with used fossil fuels, crate greenhouse effect and cause global warming. When literatures are exanimated, generally, it is emphasized using renewable energy sources such as wind and solar energy. Besides, maximum efficiency obtained from produced energy, plays a significant role in literature. In order to use energy efficiently, waste heat and solar energy, renewable energy sources which exist only for a certain period of time, should be stored. For this, water, which has a high thermal capacity, is commonly used as storage mass. The density of the water varies depending on temperature. Therefore, the water of which temperature vary in the course of heating and cooling, is exposed to convections currents in the storage and accelerates its heat transfer. Even though this may seem advantageous at first, as the temperature gradient is decreased due to heat exchange, the heat recovery from the storage occurs at lower temperatures. This study aims to prevent convections currents and to obtain covered heat at higher temperatures. Therefore, fibreglass impregnated with water is used as tank equipment. According to the results, fibreglass impregnated with water acts like a solid body. This situation provided that heat retrieves from the thermal tank with fibreglass at higher temperatures than the thermal tank without fibreglass. However, it was observed that there is a decrease in the amount of stored energy, and the heat transfer rate decelerates.
