hi all hoping to have some questions addressed I have steam boiler with about 321sq ft of connected load, its ibr net rating is 358 sq ft. I would like to pull a FHW loop of about 26' of slant-fin 30 which i believe would equal about 13,650 btu in 2 separate zones ie 1st and 2nd floor. Also whats best way to have multiple zone FHW loop off the staem boiler use zone valves? with a main bronze pump almost like a manifold, or a separate pump for each zone. any help would be appreciated highly Thks
