Pennsylvania DCNR seeks renewable fuel to fire a district hydronic heating system, Part 1

The new facility includes a 10,000-sq.ft., 20-person office building and a 5,500-sq.ft. maintenance shop, where the department services heavy equipment. The buildings’ in-slab radiant floors are heated by two redundant Fröling P4 wood-pellet burning boilers, imported by Tarm USA, in New Hampshire. Of the boilers at Weiser, the larger unit is capable of modulating between 30-130 MBH while the smaller unit can provide heating outputs between 20-85 MBH. They run at about 86% efficiency. To improve efficiency and responsiveness of the system, Longenecker provided a heavily-insulated, 400-gal. buffer tank that provides long run times.
