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 am writing to acknowledge the quality serviceman employed by Crawford Co. I am a 65-year-old woman whose husband was out of town. I came home at eleven p.m. with the temperatures at minus nine degrees to a broken furnace. The house was at 59 degrees and I didn’t have a clue what to do. I called my husband who walked me through a couple of simple options to try to jump start the furnace. When that failed, he suggested I call Crawford. Thankfully, a serviceman called me back. I didn’t want him to come out again in the cold, so I asked him if he could talk me through a possible easy fix. He tried so patiently to help me and then decided it would be best for him to come to the house. As grateful as I was he was willing to drive from DeWitt, I was nervous about having a stranger come to the house in the middle of the night. (Old ladies worry about that.) First and foremost, when you call Crawford you can be sure of quality service, I know that. The young man, Drew, came promptly to the house and handled the situation as you would expect him to do. What was exemplary was his understanding of my upset and was pleasant, confident, capable and very reassuring. In the middle of the bitterly cold night, this man explained what he was doing in “my” terms, totally repaired and cleaned the furnace, checked flues outside and made me feel safe and warm. Those are things that company training cannot instill in a person. I thank Crawford for employing this man and I thank Drew for helping me when I was most upset. My hope is that he would be recognized and rewarded for his abilities to do his job, but also his kindness and understanding of people.
