The six 1,400 MBH cast-iron oil-fired boilers needed to be replaced. With 36” doorways for access, the Laars boilers were a good fit. The 3,000 MBH gas fired boilers heat the entire building utilizing perimeter and fan coil units. There are also package units in the building that are fed with steam bringing in 100% outside air. The Laars MagnaTherm 3,000,000 Btu boilers run on their own reset curves and are supplied an on/off signal from the BMS system.

Denron Plumbing and Heating was the contractor. Joel Pickering Project Manager oversaw the project .
