Highlights of Job
At each school the domestic hot water was being heated by the main steam boilers year round. This meant that even when there was no need for heating in the buildings the boilers would continue to run to provide domestic hot water. Now when the outside temperature is warm enough that comfort heating is not required the school personnel can shut off the steam boiler and startup the condensing boilers. At two schools we also provided for a small amount of reheat from the new boilers through a heat exchanger to temper the discharge of the that take in a large amount of outside air.
