The scope of the project was to replace the existing cast iron boilers and water heater with three high efficiency modular gas fired boilers. Boiler #3 is equipped with an internal copper coil to produce domestic hot water as well as heat, eliminating the need for a separate gas-fired water heater and the 1000 gallon hot water storage tank.

Controls
The PLC-based control system is housed in a free standing control cabinet featuring a 15" color touch screen from which all operations and set points are viewable and adjustable. This system is Ethernet based to permit remote access from a PC or an iPhone. The control cabinet includes individual burner management controls. |
The plant master controller provides lead-lag control and staging of the boilers based on the load required. In addition, it provides setback operation of the boiler plant controlled by the internal clock and calendar. The plant master also controls the operation of the building's circulator pumps using lead-lag control and variable speed controls. |
