An exclusive 55-unit condominium in downtown Birmingham.  A failing boiler plant with lack of available replacement parts was source of pain for the facility staff to provide reliable heating for the resident owners.  The low water temperature loop was an ideal application for the Raypak XTherm heating boilers.  The owner was impressed with the excellent reliability of Raypak water heating system that was part of the original construction, so they insisted on changing to Raypak for the heating plant.
