LANCASTER, Pa. — U.S. Boiler Co. has significantly expanded its line of condensing, gas-adaptive boilers with a larger combi size and several heat-only models.
Introduced last spring, the high-efficiency Alta Combi boiler (136 MBH DHW/120 heating) grew rapidly in popularity, and the trade anticipated a wider size range and heat-only options. The stainless steel Alta Combi boiler is now available in 200-MBH DHW input (5.2-gpm/150-MBH heating input). In addition, Alta heat-only models are available in 120, 150, and 180 MBH.
