In this research a floor heating solar system had been studied and installed in renewable energy lab in the Mechanical and Electrical Engineering Faculty-Damascus University. The ssystem was simulated by using Trnsys program, and experimental results were compared with theoretical results given by Trnsys. Results were so close considering thermal losses and measuring faults. Finally project's feasibility was calculated in order to get saving rate and payback period were calculated. © 2011 Published by Elsevier Ltd. Source

Light has been shed in this research upon the actuality of investing solar energy in Syria in concern with implemented projects, under constructions, and issued governmental legislations in order to encourage such tendency. In addition, to conduct feasibility study for providing all Syrian regions by house solar heating devices ( DHW), and to calculate savings, repayment period, and the percentage of CO2 that would be eliminated © 2012 Published by Elsevier Ltd.

By process of time, and increasing demand for fossil ,a tendency towards renewable energy started for different uses, the most important of which is : power generation, and water heating ,by using solar power .Since, mostly, the average temperature for heating water given by solar power is [50CD],and radiators heating need water of [70-90 C°], temperature, as such floor heating is suitable in thermal applications. Radiant-floor heat is commonly designed for residential applications, where ventilation requirements are often met by operable windows, and cooling is not mandatory. Other applications include large open buildings, such as airplane hangars, where providing heat at the floor is much more cost-effective than heating the entire volume of air in the space. Water in the radiant-floor loop is often around [45C°], depending on the floor finish. This is a lower temperature than forced hot-air systems, and reduces the energy required to heat the building. Buildings that have high ceilings, large windows, or high infiltration rates or that require high air change rates can save additional energy by using radiant-floor heat. This research deals with the problems arising from the floor heating solar systems execution in concern with (large size of the storage tank and high cost of Constituent .etc) The studied room exists in renewable energy lab in the Mechanical and Electrical Engineering Faculty-Damascus University. Heating load and the step between pipes were calculated, and a low flow was applied on both sides of the circuit which was connected to a stratification storage tank, finally the system was simulated by using Trnsys program. © 2012 Published by Elsevier Ltd.
