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. 

WHAT ARE PEOPLE SAYING

I want to express my appreciation for the excellent work your guys did installing the HVAC system in our new office. Chris is very good at what he does and we are very happy with our new system. It is obvious they take pride in their work by looking at the way they laid out the ductwork and piping in the utility room and ran the lines to the a/c units. Whenever an issue arose, Chris did an excellent job of coming up with solutions. Our local HVAC guy was doing the plumbing on this job, and I heard that he commented, those Crawford guys really know what they are doing.
