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

Last week we had a plumbing issue that needed to be addressed asap. Unfortunately, it was a leaking pipe and fitting from the community college side of a city owned building. Their preferred plumbing contractor (Crawford Company) was contacted and the service guy (Brock) was there immediately to inspect and evaluate the repair. The job was done quickly, neatly, and was not any inconvenience to the public (no water was required to be shut off). I wanted to send a thank you and compliment the Crawford service guy (Brock), excellent job
