This is a solar radiant heating job for a very well known builder/architect in the city of chicago.  Paragon Mechanical was brought into this project to design and build Chicago's most efficient heating system available today.  This is exactly what we did!  Through the power of the sun and lower temp radiant design we built a solar radiant heating system that is truly a one of a kind.  This system provides all the domestic hot water and all the heating for the building.
