“…In the experiment, which is carried out with only water without mixing, the temperature of the water increased from 29.3 o C to 41.8 o C within 90 minutes, resulting in a temperature increase of 12.5 o C. According to the results obtained, it is determined that the pure water + aluminum oxide mixture heated 59.52% more than the normal unmixed water. In another study, it is observed that the pure water + aluminum oxide mixture is 61.1% more efficient than the normal unmixed water in the yield value calculated according to the ASHRAE 93-2003 standard [24].…”

The inclusion of solar energy, which is a renewable energy source, in heating systems in buildings provides significant advantages. To make heating with solar energy sufficient and efficient, nanofluids are used in solar collectors. In this study, a hybrid heating prototype is produced, a control mechanism controlling the operation of the hybrid system is established and tests are carried out by including monoethylene glycol, propylene glycol, aluminum oxide, copper oxide, titanium dioxide, especially triethylene glycol-based nanofluids in the system. Finally, a new nanofluid is obtained by mixing triethylene glycol with aluminum oxide and is tested on the prototype. With the tests carried out under the same conditions, the temperature differences of the nanofluids in a certain time period are observed and recorded. It is observed that the mixture of water and triethylene glycol provided the lowest temperature increase by providing a temperature increase of 8.6 °C in the range of 0-90 minutes. It also is observed that the highest temperature increase is achieved with the 21 °C temperature increase of the pure water and aluminum oxide mixture. Although the water and triethylene glycol mixture performs more inefficiently than other mixtures, it is thought that it can be used for heat storage since it heats up for a long time and cools down for a long time.
