IEA has done an organization with the attendance of USA, Germany, Italy, Norway etc. to innovate the solar space heating systems. These countries lay the foundations of "Solar Combisystems" by presenting the extent of TASK 26. In this paper, an experimental study has done to improve the existing solar space heating systems in Turkey. Experimental system has built up by devising thermal stratified boiler and internal working parameters, external system parameters have been measured between December 2010 and May 2011. The system includes two closed flow cycle. There are three control units to control flow cycles which are placed into the system. Also system presents new approach on floor heating method by using copper finned-copper flow tubes for space heating. The new approach in design and application state has a positive impact on the energy flow of the system. The results show that energy saving ratio is performed between 59% and 89% monthly. The system, supplies the energy demand of the space that is needed to provide comfort conditions. Also fractional solar consumption (FSC) change is investigated daily, monthly and annually. Annual FSC value of the established system is approximately 83%. (C) 2012 Elsevier Ltd. All rights reserved.
