The Alpine
Safe, reliable, and efficient that's the Alpine
boiler, NEW from Burnham! The Alpine is a
fully modulating condensing gas boiler with a
95% AFUE. At the heart of the Alpine is a
durable, high efficiency stainless steel heat
exchanger. Water flows through a series of
stainless steel coils that completely
surround and capture the heat from the
combustion chamber. This design ensures
maximum heat transfer at all times and the
ability to condense, which further enhances
efficiency. Complete modulation of firing
rates ensures that the boiler will only operate
as much as it needs to in order to answer the
call for heat. The new Alpine it's the peak of
efficiency, safety, and reliability... only from
Burnham Hydronics!
