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.
