A summary of the boilers is provided in Table 5. The existing fire tube boiler was replaced in 2008 while the newer condensing boilers were installed in 2016 after the previous firetube boilers experienced a failure in 2016. The heating plant operates as a constant volume primary / secondary system. The primary heating water pumps distribute water to each building where secondary distribution pumps circulate water through the various campus buildings. During the winter season three (3) boilers are required to operate to meet the campus connected heating load. During the summer months one (1) boiler is required to maintain dehumidification loads throughout campus.
