The Alpine is a Burnham-brand condensing gas boiler, manufactured by the U.S. Boiler Company. This high-efficiency boiler line offers adjustable firing rates and a stainless steel heat exchanger. The Alpine is available in six different models, including both floor and wall-mount versions.
The Burnham Alpine boiler is up to 95 percent energy efficient, with models ranging from 80,000 BTU to 399,000 BTU input capacities. Equipped with the Sage 2.1 boiler control system, the Alpine saves energy by circulating residual warm water before firing the boiler. The system allows up to eight Alpine units to be staged together. The Alpine and other U.S. Boiler Company products are manufactured and assembled in Lancaster, Pennsylvania.
