The steam is supplied by two 100 horse power return tubular boilers, located at the southeastern corner of the building and provided with a 28-inch stack 60 feet high. The heat is distributed at 15 pounds pressure throughout the three bays by means of coil radiators, which are placed vertically against the side walls of the shop and storeroom.
