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. 


Jeff just left and I thank you for sending him over. He is very friendly and helpful. He even went the extra mile and looked at two other vents and put a bead of caulk on them (going the extra mile). Again, I really do appreciate the friendly and helpful employees at Crawford. I thank you (Brian Bausch) again for getting back to me whenever I had a question on something. No matter if it was during your work day or in the evening after cutting your lawn, you made yourself available. Please let each of your employees that have done work at our home know that we appreciate them and keep doing what they are doing.
