Installed approximately 600 square feet of snow melt in a six-unit apartment complex's sidewalk area on either side of building. Used existing 500,000 BTU cast iron boiler (for six unit baseboard system) by adding additional pump, brazed plate heat exchanger, snow melt pump and Tekmar full automatic control system. Challenge: Design efficient and affordable system to replace 40 year old, single 400,000 BTU cast iron boiler serving two separate units, utilizing 9 cast iron radiators per apartment.
Solution: Removed existing unit and installed additional gas meter and piping. After heat loss calculations, installed two separate 140,000 BTU cast iron boilers. Removed all existing 2" and 3" horizontal piping in basement area and installed 5/8" P.A.P. Home Run system. Separate supply and return line to each individual radiators and installed one manifold for each floor.
Gave owner option for future to install thermostatic radiator valves on each radiator, smart pumps and 60 gal indirect boilers for additional savings.
