The aim of this work is to develop dual purposes solar heating system using a heat pipe evacuated tube solar collector. The heat transfer fluid between the thermal loads and the solar collector loop was heating oil. The study provided two thermal loads; a solar water heating system and a solar baking/cooking system that had experimentally investigated under various weather conditions. The experimental pilot unit was installed in the Solar Energy Department, National Research Centre, Giza, Egypt. Several test runs were performed to measure all assigned parameters that affect the system performance. The system is designed to provide hot oil surrounding the inner vessel of the baker with a temperature up to 250o C while the raw food can be baked/cooked and the outlet thermal energy can be used for heating water via an immersed coil in the hot water storage tank; then the relatively cooled oil is returned to the solar collector via hot oil circulating pump. The tested system can be positively contributed to baking and cooking purposes and providing hot water as well. It is considered an environmentally friendly system and can significantly enhance sustainable communities. The system is capable to produce hot water temperature up to 85 oC and an average temperature of about 60 oC during the day which is suitable for residential purposes and industrial process as well The auxiliary heating system can be an electric source in case of using in urban areas and can be renewable energy source like biogas or hydrogen fuels in rural and isolated areas.
