Mineral Community Hospital

“Self-Contained Complete Boiler System of Modular Design”

Project Description

Mineral Community Hospital was using oil, propane and electricity to supply the heating and domestic hot water energy requirements of the hospital and the adjoining clinic. A pellet wood fired boiler system proposed by PES had been sized at a 1,000,000 BTU/hr. input with a useable output of 885,000 BTU/hr. The boiler was sized to produce 90% of the peak load conditions of the combined energy requirements of the hospital and clinic. The existing oil-fired boilers will be set to provide additional energy as necessary to meet the energy demand during severe low-temperature conditions.
