Performance and Efficiency Consideration of a Floor Heating System Working with the Heat Collected from the Sun at Different Climate Conditions

Present paper introduces a novel floor heating system which provides its heat by the Sun. This integrated system incorporates the advantages of both floor heating and free energy supply simultaneously. It is examined for a special building under different climate conditions. Based on the obtained results for very cold climate conditions the new system’s performance is significantly low. This is mainly due to the working fluid’s high temperature limit which causes the supporting solar system to be too much bigger than the normal one which is sufficient to heat up the building. The most significant advantages of the proposed design is for moderate climate conditions where the inlet temperature limit does not impose an extra area and, hence, cost for the solar system. For this condition the integrated system has superior advantages to the traditional ones.
