Project Summary:
Crawford Company removed an existing cast iron sectional hot water boiler, primary piping, and hydronic accessories. Crawford installed (2) Weil McLain ECO-155 95.1% AFUE efficient wall hung boilers. The boilers were installed will new Grundfos multi-speed zone circulators, and primary circulators. This application called for CSD-1 compliant controls, ASME expansion tank, emergency boiler shutoff, and back flow prevention. This system serves the heating needs of nine units in the apartment building. 

The existing traditional 40 gallon water heater was also removed and a new Aqua Plus 55 indirect fired water heater was installed on the boiler system. This water heater is set up to take priority heating calls over the space heating to allow for the buildings domestic hot water needs to be met. The water heater is heated off the 95.1% efficient boilers and can produce hot water very quickly. 


I just wanted to extend a huge "thank you" to you and your team. Crawford does a fantastic job for us that sometimes goes unappreciated. I wanted to take this time to let you know that we are grateful to have such a strong contractor doing quality work in our plant. I personally work with your guys, Darrell mostly, but all do a great job. So again, THANKS!! for the work that your team does. Please pass this along to your crew so they know that we do see and appreciate their work ethic and fabrication skills they bring to our plant on a daily basis.
